SAFETY PRECAUTIONS 1.

REGULATIONS

CompAir UK Ltd compressor safety relates to the document BS EN1012-1 Compressors and Vacuum Pumps - Safety requirements and the UK Pressure Systems and Transportable Gas Containers Regulations 1989.

RISK OF DANGER

• Most accidents which occur during the operation and maintenance of machinery result of failure to observe basic safety rules or precautions. Recognising a situation that is potentially hazardous can often prevent an accident.

RISK OF ELECTRIC SHOCK

• When handling, operating or carrying out maintenance on the unit, personnel must observe safe engineering practices and all relevant local regulations. The attention of users is drawn to the Health and Safety at Work Act 1974, and the regulations of the Institution of Electrical Engineers.

RISK OF HIGH PRESSURE

• CompAir UK Ltd cannot anticipate every possible circumstance, which might represent a potential hazard. The WARNINGS in this manual are therefore not all inclusive. If the user employs an operating procedure, an item of equipment or a method of working which is not specifically recommended by CompAir UK Ltd then they must ensure that the unit will not be damaged or made unsafe and that there is no risk to persons or property.

RISK OF HOT SURFACE

RISK OF GAS EXHAUST

• Failure to observe these precautions given under "Safety Precautions" may be considered dangerous practice or misuse of the compressor • Read and understand all WARNINGS, CAUTION AND MANDATORY LABELS on the unit before operating or carrying out maintenance or servicing. 2.

WARNINGS, CAUTIONS & NOTES

• The following details for this Safety Section relate to the ESSENTIAL SAFETY REQUIREMENTS referred to in Directive 89/392/EEC, Amended 91/286/EEC.

• Warnings call for attention to operation procedures involving specific hazards which could cause injury or death and are identified by the following:-

CONSULT MANUAL 3.

GENERAL SAFETY PRECAUTIONS

• When using cleaning solvents, local Health and Safety Regulations must be complied with. Provide good ventilation and use suitable protection such as a breathing filter mask, safety glass, protective apron and gloves. • Safety footwear should be compulsory in all workshops. Safety helmets must be worn if there is any risk of falling objects. • If using compressed air for cleaning purposes, ensure safety regulations are complied with and appropriate clothing worn. 3.

GENERAL SAFETY PRECAUTIONS (Cont.)

gassafety.doc

04/09/02

Page 7

CompAir UK Ltd PUBLICATION GAS SAFETY Page 8

• Never direct compressed air onto your skin or at other people. Never use compressed air to clean loose dirt from clothing. • Before releasing compressed air through a hose make sure the free end is held securely so that it cannot whip and cause injury.

• Pipework or other parts with a surface temperature above 70°C, which may be accidentally touched in normal operation, must be guarded or insulated. Other high temperature pipework should be clearly marked and all pipework should be clearly marked.

• Avoid injury by using a hoist to lift heavy loads. Check that all chains, hooks, shackles and slings are in good condition and are of the correct capacity. They must be tested and approved according to local safety regulations.

5. OPERATIONAL PRECAUTIONS • Competent personnel under a qualified supervisor must only operate the compressor.

• Cables, chains or ropes should never be applied to lifting eyes. Always use an appropriate shackle or hook, properly positioned. Arrange lifting cables so that there are no sharp bends. Use a spreader bar to avoid side loads on hooks, eyes and shackles and never leave a heavy load unattended. • When a load is on a hoist stay clear of the danger area beneath and around it. Keep lifting acceleration and speed within safe limits. 4. INSTALLATION PRECAUTIONS • Competent personnel under a qualified supervisor must only carry out installation work. • A fused isolator switch must be fitted between the main power supply and the compressor. • Precautions must be taken to ensure that no injury is caused to passers-by through loose clothing being sucked into compressor intake. • Ensure that the discharge pipe from the compressor to the user pipework, receiver or storage is free to expand and that no flammable material is within the vicinity. If any such material is close-by take steps to preclude ignition. • A manual shut-off valve should be fitted in the discharge line to allow the compressor to be isolated. Non return valves cannot be relied upon for isolating parts from a pressure system. A safety valve must be installed between any compressor unit and the isolating valve. • A pressure-reliving device must be fitted to every pressure vessel, or equipment containing gas or gas above atmospheric pressure. Never remove or tamper with safety devices, guards or insulation fitted. In order to limit the risk of Legionnaires Disease, CompAir UK LTD advise caution with the use of cooling towers for water cooling the compressor. Closed circuit or direct mains cooling is preferred.

• Do not operate compressor with any removable inspection cover removed e.g. crankcase doors, valve covers etc. • Never remove or tamper with safety devices, guards or insulation materials. • The compressor must only be operated at the supply voltage and frequency for which it is designed. Always isolate power before maintenance or servicing. • When mains power is ON, lethal voltages are present in the electrical circuits and extreme caution is need when essential work is carried out on the electrical system. ALWAYS CONSULT A QUALIFIED ELECTRICIAN BEFORE ANY SUCH ESSENTIAL WORK. • Do not open starter compartment to touch electrical components while voltage is applied unless it is necessary for measurement, test or adjustment. Such work should always be carried out by a qualified. Electrician with appropriates tools and protection against an electrical hazard. • If the unit is equipped with a Remote Control device, attach warning notices stating "THIS UNIT CAN BE STARTED REMOTELY" in prominent locations, one on the outside of the unit, the other inside the control compartment. • As a further safeguard, take adequate precautions that no one is working or checking the unit before attempting to switch on remotely controlled equipment. Attach a "CHECK THAT ALL PERSONNEL ARE CLEAR OF UNIT BEFORE STARTING" or similar notice. • Compressed gas and gas piping, together with cooling water piping and other parts, with surface temperature greater than 70°C and may be accidentally touched, should be guarded or insulated.

CompAir UK Ltd PUBLICATION GAS SAFETY Page 9

5. OPERATION PRECAUTIONS (Cont.) • If there is any indication that the compressor is overheating it must be shutdown. (A high air or gas temperature switch is fitted as standard to guard against operating with excessive temperature). Beware of burns from hot oil and water when working on a unit recently shutdown.

occurs washes with limewater and seeks medical advice. Pre-Maintenance Operation • 1. Isolate the compressor from the main electrical supply. Lock the isolator in the OFF position and remove fuses.

• Do not operate the unit when guards provided for protection for all rotating and reciprocating parts have been removed for essential maintenance. Secure guards following any servicing or repair.

• 2. Attach a label " WORK IN PROGRESS - DO NOT APPLY VOLTAGE".

• Local noise regulations must be observed. Ear defenders are suggested by Noise at Work Regulations 1989 when the level is greater than 85 dB A at one meter. Be aware high noise levels can interfere with communication.

• 3. Close the isolating valve between the compression unit and user's pipework. Close the isolating valve in the cooling water inlet pipe. Attach a label "WORK IN PROGRESS - DO NOT OPEN".

6. MAINTENANCE & REPAIR PRECAUTIONS • Competent persons under qualified supervisor must carry out maintenance repair and modifications.

• 4. Check that all pressurised gas trapped in the system is released to atmosphere or safely to gas storage. Check that all pressure gauges register zero.

• The compressor will have a preserving oil applied to interior surfaces (Oil lubricated models). Oil free models will have desiccant bags in valve covers and distance pieces.

• 5. Ensure that the cooling water system has been drained.

• Handling components such as seals, gaskets and diaphragms should not present a personnel hazard. Preservation oils again should not present a personnel hazard if handled under normal handling practices. • Whilst compressors are asbestos free, treat all damaged gaskets as asbestos - when the Asbestos at work regulations apply. • Viton 'O' seals under normal operating conditions are safe. • However, should there be a fire within the compressor or these seals are likely to exceed a temperature of 300°C the material will decompose. • Degraded Viton gives off Hydrogen Fluoride fumes and if in contact with the skin an acid formed causes severe burns. • If Viton seals appear charred or gummy do not touch with unprotected hands: use neoprene or PVC gloves.

• 6. Check that the drain valve on the delivery manifold is clear and gas pressure has been released. • 7. Check that all interstage drains are open to ensure any gas trapped between stages has been released. • Stand clear of all valve covers when removing the securing screws. • When removing valve covers for valve replacement, ensure a minimum of two threads is left engaged on the valve cover securing screws. Lever the valve cover until the 'O' seal is disengaged from the port in the cylinder head. Remove the securing screws and take out valve cover. • Use only lubricating oils and greases approved by CompAir UK LTD to avoid potential hazards especially the risk of explosion or fire and the possibility of decomposition or generation of hazardous gases. • Always clean oil spills from the surrounding floor before and after maintenance work.

• Wash the area with limewater and avoid breathing any fumes. If contamination of the skin

MAINTENANCE & REPAIR (Cont.)

• Make sure all instructions concerning operation and maintenance are strictly followed and that the complete unit, with all accessories and safety devices, is kept in good order. • The accuracy of pressure gauges and temperature switches should be regularly checked at least 13 month intervals and thoroughly examined at least every 48 months. They must be renewed or service exchanged when acceptable tolerances are exceeded.

• Keep the compressor clean at all times. • Protect components and exposed openings by covering with a clean cloth or tape during repair or maintenance work. • Protect the motor, intake, electrical and regulation components against the entry of moisture e.g. steam cleaning. • Precautions must be taken when carrying out welding or any repair operation which generates flames or sparks. The adjacent components must be screened with non-flammable material and if oil present, the system must first be cleansed thoroughly by steam cleaning.

• Protection devices should be tested at each regular service interval and replaced or service exchanged if not functioning correctly. The maximum pressure for safety valves under fault conditions is 1.10 times the set pressure, the set pressure being a minimum of 1.05 times the maximum operating pressure to ensure seat tightness.

• Condensate (oil and water mixture from compression process) must be regarded as trade effluent and is therefore not suitable for discharge into a surface water sewer, soakaway or watercourse.

• Never use a light source with an open flame for inspection.

PROTECT THE ENVIRONMENT USE APPROVED METHODS OF DISPOSAL.

• Before dismantling any part of the compressor be sure that all heavy movable parts are secure. • After completion of any maintenance or repair ensure that no tools, loose items or rags are left on or inside the compressor. • Do not use any flammable liquid to clean valves, filter elements, cooler passages, pipe bores or any component carrying a flow of air or gas during normal operation. If chlorinated hydrocarbon substances are used for cleaning, safety precautions must be taken against toxic vapours, which may be released. DO NOT USE CARBON TETRACHLORIDE. • Precautions must be taken against using acids, alkalis and chemical detergents for cleaning machined parts. These materials cause irritation and are corrosive to the skin, eyes, nose and throat. Avoid splashes and wear suitable protective clothing and safety glasses. Do not breathe mists. Ensure water and soap is readily available. • When disposing of condensate, old oil, used filter elements and other parts and waste material of any kind make sure that there is no pollution to any drain or natural water course and that no burning of waste takes place which could cause pollution of the atmosphere.

7. PRECAUTIONS IN THE EVENT OF FIRE • Use extreme caution when handling components that have been subjected to fire or very high temperature. Some components may contain fluoroelastomer materials, which decompose under these conditions to form highly corrosive residues. Skin contact can cause painful and penetrating burns resulting in permanent skin and tissue damage.

DRY GASES

Lubrication is the introduction and maintenance of a continuous film of oil between two moving surfaces. When this breaks down, wear occurs. In an gas compressor the agitation, caused by the oil distribution and recovery system, results in the lubricant absorbing some gas whilst it is in the crankcase and cylinders. The oxygen in the entrained gas gradually forms and maintains oxide skins on the moving surfaces. These improve the adhesive strength of the oil film, preventing its breakdown. When gas is being compressed and there is no oxygen present, even in small amounts, the help from these skins is not normally available. However, it has been established that if moisture is present, film breakdown is prevented. The reason is that gas entrained in the water at source, provides the oxygen for oxide skin formation. If the gas is dry (we define this as less than 50 ppm by weight) and if no oxygen is present (less than 10 ppm by volume) it is necessary to use a special lubricant capable of maintaining a high film strength to prevent its breakdown. The properties needed are a stronger than normal adhesion to the metal surfaces and additives which will help oxide film formation. These are provided by an oil which has a HIGH viscosity, a HIGH level of anti-wear additives and a LIMITED amount of anti-oxidant additives. The lubricant we recommend for this duty is Anderol 1200. When commissioning or re-commissioning the compressor, it is recommended that the machine is run on air for 10 hours using the recommended oil as this will speed up the formation of oxide skins before changing to gas and Anderol 1200.

TYPICAL GAS PURGING INSTRUCTIONS Before allowing any Natural Gas to enter the compressor or ancillary piping the whole system must be purged free of air in accordance with the following procedure. If in any doubt as to the efficiency of the purging, ALWAYS REPEAT THE PROCEDURE. Feeding the purge gas at a pressure equal to the inlet pressure to the compressor, will speed the process. After any maintenance or repairs have been carried out which involves dismantling and opening up gas containing parts, the system must always be re-purged. PURGING PRIOR TO INITIAL START-UP Purging with Nitrogen Connect nitrogen to the inlet purge valve PGE01. Close inlet valve ISOL01, ISOL02, DDV valve ISOL09, filtration isolation valve ISOL68 and purge valve PGE061. Open recovery vessel valve ISOL08 and compressor inlet purge valve PGE02. Purge nitrogen through until air is displaced. This can be checked with an oxygen meter at the vent stack. Close recovery vessel valve ISOL 08 and open DDV valve ISOL 09 select manual operation on Control Panel and open Solenoid valve SOL01. Purge nitrogen through until air is displaced. Close compressor inlet purge valve PGE 02 and open delivery purge valve PGE 61. Purge nitrogen through until air is displaced by checking with an oxygen meter at the delivery purge valve. Most of the compressor system should now be filled with nitrogen. If the downstream equipment needs to be purged with nitrogen then the compressor can be run by feeding nitrogen into the inlet vessel and maintaining the required inlet pressure. The filtration will be pressurised before the pressure-maintaining valve PCV 61 opens. Shut off nitrogen supply when complete. Purging with Gas Vent nitrogen from vent system by opening the filtration isolation valve ISOL 62 and venting nitrogen from the recovery vessel ISOL 07 ensuring a small positive pressure is kept in the system. The filtration isolation valve ISOL 62 should then be closed. If the downstream equipment has been purged with nitrogen then it should be vented to a small positive pressure. Open inlet gas isolating valve ISOL 01 and open inlet gas solenoid valve SOL 01 by switching vent valve inlet switch on starter to Hand. This will allow gas to enter the system. Open recovery vessel drain ISOL 07 until gas is sensed and then vent from delivery purge valve PGE 61. The compressor system should now be filled with gas.

COMPRESSOR MAINTENANCE Releasing gas To isolate compressor close DDV and recovery vessel valves ISOL 09 and ISOL 08. Vent gas from compressor purge valve PGE 02. Repurging with gas Open compressor purge valve PGE 02 and DDV valve ISOL 09 until gas is present. Close DDV valve ISOL 09 and open recovery vessel valve ISOL 08 and purge gas to PGE 02. Close PGE 02 and open DDV valve ISOL 09. FINAL COALESCER Releasing gas Close filtration isolation valve ISOL 62 & ISOL61, expel gas into the recovery vessel via ISOL63. Close Open compressor purge valve PGE 02 to expel the gas and then open delivery purge valve PGE 61 to vent remaining gas.

GENERAL DESCRIPTION TYPICAL ARRANGEMENT st

1 Stg Safety Valve nd

2 stage Safety valve. Pressure gauge panel.

st

1 Stage cylinder nd

2 Stage cylinder Surge vessel safety valve Diaphragm Drain valves The R-5437.1.NG compressor is a reciprocating 90° vee configuration, 4 stage, single acting, water cooled machine with the 1st and 3rd stage lines on one crank throw, and the 2nd and 4th stage lines on the opposite crank throw of a counterbalanced crankshaft. The running gear consists of the crankshaft, bearings, connecting rods, oil pump, cylinder lubricator and other accessories. rd

th

st

nd

The gas end consists of two cylinder blocks - combined 3 & 4 stage – combined 1 & 2 stage. Each block is complete with individual cylinder liners, pistons, valves, valve covers, inter-stage st nd rd th st nd rd coolers for the 1 , 2 , 3 and 4 stages and condensate separators for 1 , 2 and 3 stages. st

nd

The 1 & 2 stage cylinder blocks contains renewable wet cylinder liners and are jacketed for rd th water-cooling. The 3 and 4 stage cylinder blocks contains renewable dry cylinder liners again jacketed for water-cooling. Water flow is arranged within the cylinder jackets and coolers in series to provide even and effective cooling for either sea or fresh water. First and second stage pistons are conventional trunk type, whilst the third and fourth are an integral piston and crosshead assemblies. All are fitted with split piston rings. A single combined suction and discharge (concentric) valve is fitted at the head of each cylinder. Water-cooled inter-stage coolers are provided after each stage of compression, with condensate separators after each inter-stage cooler. The water flows over the tubes and the gas through for all stage coolers. All stage coolers are withdrawable to ease maintenance. The fourth or final stage cooler cools the hot gas delivered from the fourth stage cylinder to within 5°C of the cooling water inlet temperature. The oil pump is directly driven from the crankshaft to provide a forced-feed lubrication system via a suction strainer through a filter element to the running gear. The cylinders, pistons and valves are splash/spray lubricated. A low oil pressure switch is provided to protect the running gear against lubrication failure, an oil level sight gauge is provided in the crankcase for maintaining oil to the correct level. An automatic drainage system drains each stage condensate separator at approximately 10 to 20

minute intervals for a period of 5-10 seconds into a discharge surge vessel, in-built in crankcase. This interval and period is dependent upon the ambient temperature and humidity and for high ambient high humidity conditions the interval must be reduced and the period increased. The drainage system whilst removing oil/moisture also acts as an unloading device to prevent the compressor starting under load, by bleeding off automatically all the gas in the compressor through the condensate separators whenever the compressor stops. Pressure gauges to indicate all gas stage pressures and oil pressure are located in a gauge board mounted between each cylinder block. Gas relief valves for each stage are fitted to prevent over-pressure in cylinders and coolers, and bursting diaphragms are fitted to protect the water jackets from accidental application of gas pressure to the cooling system. A pneumatic water inlet valve (if fitted) will not allow the cooling water to flow when the compressor stops this helps to prevent over-cooling. High gas temperature switches are fitted to the 3rd stage cylinder discharge, inlet (or exit from the third stage cooler) and exit from the 4th stage delivery after cooling to stop the compressor on over-temperature in the gas stream. These switches combine both a visual dial display of the temperature and again an indication of the switch setting. The compressor gas intake should be fitted with a filter to prevent solid particles entering the compressor cylinders. A non-return valve is located at the final discharge connection to prevent system pressure returning to the cylinders when the compressor is shut down.

LUBRICATION 2.3.1 MAIN LUBRICATION SYSTEM A forced feed oil pump pressurises the lubrication system conveying oil from the crankcase to the main, big end and small end bearings via a replaceable filter element . Oil thrown off the moving parts ensures adequate lubrication to all stage pistons, crossheads and cylinders. Oil returns to the crankcase and is drawn up to the pump suction through a strainer.

An oil pressure gauge indicates if over-pressure and is relieved through a safety valve within the oil pump. A protective Low Oil Pressure Switch or LOP s installed to shut-down the compressor if the pressure falls below 1 bar ( 15 psig). On starting if the oil pressure has not built up within about 10 seconds the LOP, connected to a delay timer in the motor starter control, will shut down the compressor. THE GUARANTEE MAY BE INVALIDATED SHOULD A FAILURE BE ATTRIBUTED TO THE USE OF A LUBRICANT NOT RECOMMENDED BY COMPAIR IPSWICH

2.4

CONDENSATE REMOVAL

2.4.1 DIAPHRAGM DRAIN VALVES Diaphragm Drain Valves or DDV’s are installed after each compression stage to automatically drain oil/moisture collected in each inter-stage separator and to act as unloader valves to remove any gas load on starting. All these valves are similar in design and operation – only the valve orifice and seat vary to suit each stage. Each valve to operated from first stage pressure via a three-way solenoid valve. With no gas pressure st all valves are open to the blowdown vessel. In operation, gas pressure from the 1 stage acts on the diaphragm to close the valves. A timed signal every 10 - 20 minutes actuates the three-way solenoid valve for 5-10 seconds to release the gas pressure and allow the valves to open and drain the collected condensate in each separator to drain. The sudden release of gas and condensate is passed via an integral surge vessel, to attenuate the noise, for connection to drain trap to drainage vessel, ready for safe disposal.

COMPRESSOR PROTECTION 2.5.2.1 STAGE GAS RELIEF VALVES. Gas Safety valves are fitted to all four stages. 2.5.2.2 BURSTING DISC Thin plastic membrane and PTFE/metal discs protect the cooling water system against a possible cooler gas leak, ruptured cooler tube etc. It is not intended as a protection against water over-pressure and therefore the burst pressure (17 bar or 250 psig) has no particular relationship to the cooling water system operating pressure. 2.5.2.3 PRESSURE GAUGES Glycerine filled pressure gauges are supplied for each compression stage and for monitoring the main lubrication oil system pressures. 2.5.2.4 PNEUMATIC WATER VALVE ( IF FITTED ) This valve is a normally closed diaphragm operated shut off valve to prevent cooling water flow whenever the compressor is not operating. This function is automatic since the valve is actuated by the first stage gas pressure. 2.5.2.5 HIGH GAS TEMPERATURE SWITCHES rd rd Temperature sensors are fitted into the 3 stage delivery port, exit from 3 stage separator at th inlet to 4 stage inlet and at the final delivery after cooling. Each connected to a temperature switch.

2.5.3

DELIVERY 2.5.3.1 FINAL DISCHARGE NON-RETURN VALVE Fitted at the compressor exit to prevent gas under pressure in the downstream piping or reservoir from flowing back through the machine when the compressor is unloaded and stationary.

SECTION 3

INSTALLATION INFORMATION 3.1 UNPACKING AND HANDLING

•

The compressor unit is delivered in a packing case. All openings will have been sealed with plastic plugs or adhesive tape. The packing case should be carefully disassembled to avoid damage to gauges, pipework, and valves etc. and loose components packed separately. The unit should be lifted by the eyebolts on the motor and compressor.

3.2 LOCATION It is desirable that the compressor unit is installed in as clean, cool and dry environment within the parameters stated in the ‘Leading Particulars’ section. The surface, on which the unit is to stand, must be flat and capable of bearing the total weight of the unit without distortion. In selecting the location it is essential to consider accessibility. Allow sufficient space around the installation for safe maintenance work. Sufficient clearance must be allowed to ensure that the set will not touch any obstruction or any flexibly mounted equipment, with an added allowance for maximum movement from the mounting system.

3.3 MOUNTING The compressor unit is mounted on anti-vibration mounts. These mounts should be inspected for any tear of the rubber to metal plate bond or ageing before use. Ensure the mount is not impregnated with oil or grease, and that any protective lacquer is intact. Reject any mount that is not in good condition. Lower the compressor unit onto the mounts and screw on the mount holding down nuts. Rock unit to ensure mounts is free and not distorted, and that the set will not touch any obstructions or other flexibly mounted equipment.

3.4 CONNECTIONS Note: As the compressor unit is flexibly mounted, all connections must also be flexible. Short flexible sections must be incorporated, should be suitable for the pressures and temperatures involved and capable of easy removal to facilitate maintenance. 3.4.1 GAS CONNECTIONS Suction The intake gas pressure can vary, typically between 0.02 and 1bar g from a local gas utility and must be as clean and dry as possible. Final Delivery The final delivery connection ½ ” BSPP is situated at the end of the non-return valve. The flexible connection must be suitable for the set working pressure. Unloading / Condensate Drain The unloading / condensate drain connection at the crankcase, for the surge vessel, is screwed 1½” BSPT female to accept the discharge pipe. This pipe must be led away with a minimum of bends, and must have a minimum internal diameter of 38mm (1½”). There must be no obstruction in the line as any restriction during operation may cause the safety valve at the crankcase for the surge vessel to open. Note: Condensate drainage is dirty and it is advisable to pipe direct to a suitable tundish.

3.4.2

WATER CONNECTIONS

Cooling Water The quality, quantity and temperature of the water used can materially affect maintenance. A positive circulation of cool but not cold, clean water, free from suspended particles is required for satisfactory continuous operation. Note: It is vital a suitable inhibitor is used especially in HARD WATER areas. Therefore it is recommended that a suitable water softener unit be fitted to the inlet water line. It is recommended that temperature indication or gauges are fitted to water inlet (1 ¼” BSPT) and outlet (1 ¼” BSPT) pipes to monitor water temperature rise across the compressor to approximately 10-12 °C. If this rise is too high the average water temperature is high and can cause overheating and accelerate formation of scale in the coolers and water passages. Too low a rise reduces the average temperature and may improve the cooler efficiency but can cause condensation in the cylinders. A lockable throttle valve is recommended at the inlet, installed before the pneumatic water inlet valve (if fitted), to allow adjustment the water flow to achieve the correct temperature rise then locked for security, The inlet connection is to the pneumatic water control valve (if fitted) inlet only. This valve is operated by the first stage compressor gas pressure to only allow water in when the compressor operates. Note: Continued water circulation when stationary can cause condensation within the cylinders and breakdown of oil lubrication creating premature wear. (I.e. over-cooling) Pneumatic Water Inlet Valve A compatible CompAir UK Ltd Ipswich automatic pneumatic water inlet valve can be fitted to control water supply and prevent overcooling. Water flow arrangements should be fail-safe to ensure that compressor can not run on full load without water flow. 3.4.3

ELECTRICAL CONNECTIONS

Electric Motor for Hazardous Area Zone 1 Main leads from the motor controller / starter should be brought through a suitable Zone 1 flexible armoured cable sheath to the terminal box on the side of the motor. The size of the cable shall be suitable for the supply voltage and current involved, and the terminal connections shall be as shown in the terminal box. A suitable overload device should always be fitted. An hours-run meter fitted to the motor starter is recommended for maintenance scheduling. A timer should be incorporated in the starter to de-energise the solenoid valve for between 5-10 seconds every 10 - 30 minutes to periodically, dependent upon ambient temperature and humidity. Contact CompAir UK Ltd Ipswich for more information on humidity if required. This will allow the diaphragm drain valves to operate and discharge any accumulated condensate. Adequate flexibility shall be ensured to allow for movement of the set on the anti-vibration mounts. Solenoid Valve for Hazardous Area Zone 1 The cable should be run through a suitable Zone 1 flexible armoured cable sheath from the motor controller. High Gas Temperature Switches for Hazardous Area Zone 1 The cable entry is through a conduit entry hole. Details of the terminal connections are on the switch. Cable should run through a suitable Zone 1 flexible armoured sheath. Low Oil Pressure Switch for Hazardous Area Zone 1 See High Gas Temperature Switches above. Note: When the compressor set is on flexible mounting it can become electrically insulated. A flexible braided earth strap of suitable length to ensure it will not fail under maximum movement of the set must be fitted between the set and the its seating.

4.1 SAFETY PRECAUTIONS When operating or working on the compressor unit at any time the following safety precautions must be observed. Read all starting and operating instructions before running compressor. Do not bar over or work on compressor without ensuring that all equipment is isolated from the electrical supply, and will remain isolated whilst work is in progress. Always open high pressure gas line valves SLOWLY. Never attempt to stop leakage or tighten joints or loose parts when compressor is running or parts are under pressure. The compressor must NEVER be operated with a malfunction in the oil or cooling water system. Should a fault develop in either of these, the compressor must be stopped immediately and the fault investigated and remedied.

4.2 COMMISSIONING ON AIR Remove all covers, plastic plugs and adhesive tape used to seal compressor openings during shipment. Check all electrical connections. Ensure water is available to the cooling circuit(s). Fill compressor with cool clean sea or fresh water, which must be free of suspended particles. The system is self-venting. Remove two crankcase doors and ensure that the crankcase interior is clean and free from foreign bodies and obstructions. Check that bolts on connecting rods are tight. Check for any water leaks inside crankcase. Fill crankcase with the correct grade of lubricant until oil level is up to the maximum level mark on the sight glass. IMPORTANT: Maintain oil level up to maximum mark. Replace crankcase doors. Remove all valve covers and valves. Check for signs of rust or water. Clean as necessary. Re-oil inside of the cylinders sparingly. Refit valves. Smear 'O' rings on valves and valve covers lightly with grease and replace covers. Tighten holding down nuts progressively in a "cross" sequence. Tighten to correct torque. Check all external nuts, bolts and other fastenings are tight and correctly torqued, that all external connections are made and pipework adequately supported.

Oil pump, priming plug. Oil pump. Oil Filter

Remove oil pump priming plug, using a pump type oil can, fill system with correct grade oil. Replace plug. Arrange for compressor to discharge temporarily to atmosphere (unloaded) by opening the manual

drain valve at the 4 stage separator drain and disconnect pipe, electrically disconnect solenoid valve by removing cable plug from socket connections. Remove cover in the bell housing or vee belt guard and bar over compressor several times to distribute oil and confirm free movement.

4.3 RUNNING COMPRESSOR ON AIR AFTER COMMISSIONING On completion of preliminary checks, the compressor should be run to prove operation. Ensure electrical supplies are available. Press "ON" button on motor controller and immediately press "OFF" button, checking rotation of compressor is correct. Rewire if rotation is incorrect. Rotation must be counter clockwise looking on the driving end. Restart compressor, check oil pressure is greater than 2 bar ( 30 psig), that air is being delivered from each stage, and listen for any uncharacteristic noises. Check for air leaks by using soapy water, oil and water leaks. If leaks are found, stop compressor isolate supplies and rectify. •

DO NOT TRY TO CORRECT LEAKS WHEN ITEMS ARE PRESSURISED. Stop compressor and isolate power supplies after running unloaded for 30 minutes and check that outer surfaces of crankcase and cylinders are cool. Replace solenoid valve plug. Close manual drain valve at 4th stage separator drain reconnect pipe. Open stop valve in delivery line to gas receiver. Restart compressor and continue with run, increasing pressure by 70 bar at 15 minute intervals up to working pressure. Compressor should now be running "on load" and delivering compressed air. Check the following: Oil Pressure - record at 15 minute intervals. Stage Pressures - record at 15 minute intervals. Stage Temperatures - record at 15 minute intervals. Safety valves are not leaking. Unloader valves are not leaking. Condensate drain valves operate for approximately 5-10 seconds after every 10 - 30 minutes dependent upon ambient temperature and humidity. This must to be carefully monitored, high temperature/humidity conditions will require the drain times to be more frequent, contact CompAir UK Ltd Ipswich for more details. Compare pressure and temperature readings with those figures given in Section 1.2 Check for air leaks by using soapy water, oil and water leaks. If leaks are found, stop compressor isolate supplies and rectify. On completion of test run, stop compressor.

4.4 PURGING THE COMPRESSOR READY FOR NATURAL GAS When gas is being compressed and its purity is important, it is usually a plant requirement to purge the compressor to remove any air before letting gas into the system. Where there is such a requirement, the installation will normally have purge valves fitted to allow purging gas (Nitrogen) to be discharged to atmosphere from the delivery line beyond CompAir UK Ltd supplied parts. After any maintenance or repairs have been carried out which involves dismantling and opening up the gas containing parts, the system should always be re-purged. Before allowing any process gas to enter the compressor or ancillary piping, the whole system must be purged free of air in accordance with the purging procedure which apply to the whole plant. 4.4.1 PURGING PROCEDURE If in any doubt as to the efficiency of the purging, ALWAYS REPEAT THE PROCEDURE. Feeding the purge gas at a pressure equal to the inlet pressure to the compressor, will speed the process.

CompAir UK Ltd PUBLICATION 98407/1293 Section 4 Page 28

After any maintenance or repairs have been carried out which involves dismantling and opening up gas containing parts, the system must always be re-purged. PURGING PRIOR TO INITIAL START-UP Purging with Nitrogen Connect nitrogen to the inlet purge valve PGE01. Close inlet valve ISOL01, ISOL02, DDV valve ISOL09, filtration isolation valve ISOL68 and purge valve PGE061. Open recovery vessel valve ISOL08 and compressor inlet purge valve PGE02. Purge nitrogen through until air is displaced. This can be checked with an oxygen meter at the vent stack. Close recovery vessel valve ISOL 08 and open DDV valve ISOL 09 select manual operation on Control Panel and open Solenoid valve SOL01. Purge nitrogen through until air is displaced. Close compressor inlet purge valve PGE 02 and open delivery purge valve PGE 61. Purge nitrogen through until air is displaced by checking with an oxygen meter at the delivery purge valve. Most of the compressor system should now be filled with nitrogen. If the downstream equipment needs to be purged with nitrogen then the compressor can be run by feeding nitrogen into the inlet vessel and maintaining the required inlet pressure. The filtration will be pressurised before the pressure-maintaining valve PCV 61 opens. Shut off nitrogen supply when complete. Purging with Gas Vent nitrogen from vent system by opening the filtration isolation valve ISOL 62 and venting nitrogen from the recovery vessel ISOL 07 ensuring a small positive pressure is kept in the system. The filtration isolation valve ISOL 62 should then be closed. If the downstream equipment has been purged with nitrogen then it should be vented to a small positive pressure. Open inlet gas isolating valve ISOL 01 and open inlet gas solenoid valve SOL 01 by switching vent valve inlet switch on starter to Hand. This will allow gas to enter the system. Open recovery vessel drain ISOL 07 until gas is sensed and then vent from delivery purge valve PGE 61. The compressor system should now be filled with gas.

COMPRESSOR MAINTENANCE Releasing gas To isolate compressor close DDV and recovery vessel valves ISOL 09 and ISOL 08. Vent gas from compressor purge valve PGE 02. Repurging with gas Open compressor purge valve PGE 02 and DDV valve ISOL 09 until gas is present. Close DDV valve ISOL 09 and open recovery vessel valve ISOL 08 and purge gas to PGE 02. Close PGE 02 and open DDV valve ISOL 09.

FINAL COALESCER Releasing gas Close filtration isolation valve ISOL 62 & ISOL61, expel gas into the recovery vessel via ISOL63. Close Open compressor purge valve PGE 02 to expel the gas and then open delivery purge valve PGE 61 to vent remaining gas.

4.5 ROUTINE ATTENTION WHILST RUNNING At two hourly intervals, check pressure on gas and oil pressure gauges. Abnormal readings must be reported and investigated. Check motor bearings are not overheating. Ensure drains operate at approximately pre-set time interval. Check that no gas relief valve is operating continuously. Note for rectification when compressor is stopped any slight gas, oil or water leaks.

CompAir UK Ltd PUBLICATION 98407/1293 Section 4 Page 29

4.6 STOPPING PROCEDURE When compressor has been stopped, by means of stop button on control panel, isolate from electrical supply and; Check for oil and water leaks and rectify. Rectify any gas leaks noted while compressor was running. After approximately two hours remove drain plug from sump and drain off any water which may have accumulated. Do not drain oil. An excess of water in crankcase should be investigated. Replenish oil where necessary. Close off stop valve on discharge line to relieve gas reservoir back pressure from compressor non-return valve.

4.7 PREPARATION FOR SPECIAL ENVIRONMENT No special preparations are required other than making sure that should the compressor operate in sub-zero temperatures, adequate precautions must be taken to ensure water is not allowed to freeze in the compressor water jackets, pipework (or sea water/fresh water heat exchanger when fitted).

4.8 STARTING AFTER LONG PERIOD OF IDLENESS Check that all-external nuts, bolts and other fastenings are tight. Check associated and external pipework is intact and adequately supported. Turn compressor over a few times by hand to ensure unrestricted rotation. Ensure cooling system water is available. Open 4th stage, manual drain valve. Start compressor. Listen for any unusual noises during first few minutes of run. Close 4th stage, manual drain valve. Check gas pressure gauges. Check that no gas safety valve opens continuously. Ensure separator drains operate at approximately 10-30 minute at pre-set intervals.

4.9 INHIBITION FOR STORAGE RUNNING ON AIR 4.9.1 INHIBITION FOR UP TO SIX MONTHS Disconnect compressor from the GAS system. Run on AIR with the recommended oil. Run the compressor for 30 minutes on light load with the final delivery pipe disconnected and with all separators open. Cut down the cooling water supply during this run so that the water outlet temperature is from 38°C to 49°C. After 30 minutes stop the compressor, turn off the cooling water, disconnect the water supply and drain off the water. EITHER: Dry out the water jackets with compressed air, if available. Insert air hose at water outlet connection and pass air through jackets until water ceases to flow from water inlet connection. IMPORTANT: Do not pressurise jacket with air during this procedure. OR: Alternatively, if air is not available, fill jacket with PX10 water-displacing fluid and allow standing for 15 minutes before draining off. Remove and clean compressor valves and wipe out any moisture in valve pockets and passages. Immerse valve units in PX4 fluid and allow surplus to drain off. Insert PX4 into each cylinder, allowing approximately 1/3 cc. of fluid to each square inch of cylinder surface area. Coat all surfaces and gas passages. Replace valves carefully and coat valve covers with PX4. Seal all screw openings with threaded plastic or metal caps and flanged openings with PX4 - coating shims clamped between the flanges, and attach a warning label to this effect.

4.9.2 LONG TERM STORAGE Check that the compressor has been run on AIR with the recommended oil. Drain oil from the sump, preferably while still warm, and till to normal level with PX4 fluid. Run the compressor for 30 minutes on light load with the final delivery pipe disconnected and with all separators open. Cut down the cooling water supply during this run so that the water outlet temperature is from 38°C to 49°C. After 30 minutes stop the compressor, turn off the cooling water, disconnect the water supply and drain off the water. EITHER: Dry out the water jackets with compressed air, if available. Insert air hose at water outlet connection and pass air through jackets until water ceases to flow from water inlet connection. IMPORTANT: Do not pressurise jacket with air during this procedure. OR: Alternatively, if air is not available, fill jacket with PX10 water, displacing fluid and allow standing for 15 minutes before draining off. If it is impossible to run the compressor, remove the crankcase doors and coat running gear and crankcase with PX4 using spray gun, rotating compressor slowly by hand. (When completed, pistons should be in mid-stroke position in readiness for inhibition of cylinders etc.) Replace crankcase doors. Remove and clean compressor valves and wipe out any moisture in valve pockets and passages. Immerse valves in PX4 fluid and allow surplus to drain off. Insert PX4 into each cylinder, allowing approximately 1/3 cc. of fluid to each square inch of cylinder surface area. Coat all surfaces and gas passages. Replace valves carefully and coat valve covers with PX4. Seal all screwed openings with threaded plastic or metal caps and tape afterwards. Seal flanged openings with PX4 - coating shims clamped between the flanges and attach a warning label to this effect. Attach instruction label "DO NOT ROTATE THIS MACHINE" For any compressor which is in storage for a long period, a six-monthly inspection is to be carried out as follows; Remove the valve covers, valves and crankcase doors. Inspect the machine for signs of corrosion and carefully remove any rust that has formed. Turn the compressor round by hand to ensure that the running gear is free. Coat the running gear and crankcase with PX4 using a spray gun, rotating the compressor lowly by hand. (When completed, pistons should be in mid-stroke position in readiness for inhibition of cylinders etc.) Replace the crankcase doors. Immerse valve units in PX4 fluid and allow surplus to drain off. Insert PX4 into each cylinder, allowing approximately 1/3 cc of fluid to each square inch of cylinder surface area. Coat all surfaces, including bottom surface, of the cylinder air passages. Coat the valve covers with PX4 and replace the valves and valve covers. Check that all openings are still sealed.

4.10 FAULT GUIDE WARNING 1. BEFORE PROCEEDING WITH ANY MAINTENANCE ON THE COMPRESSOR IT MUST BE STOPPED ISOLATED ELECTRICALLY AND MECHANICALLY, COMPRESSOR GAS INLET AND OUTLET VALVES CLOSED AND VISIBLE WARNING NOTICES DISPLAYED. 2. IN ADDITION ALL INTERNAL PRESSURE MUST BE RELEASED WITH THE UNIT ISOLATED FROM THE STORAGE RESERVOIR AND THE WATER SUPPLY SHUT OFF. NOTE: A safety valve opening indicates excessive pressure and under NO CIRCUMSTANCES must a safety valve be screwed down to accommodate excessive pressure. THIS IS DANGEROUS. If safety valve opens or appears faulty shut down compressor immediately and investigate. If fault appears immediately or shortly after a service, first examine those parts disturbed during the service. Following is a list covering the probably causes of operational faults, together with the suggested remedies. Before investigating a potential fault, ensure however that: Cooling water temperature, temperature rise across the machine, and flow rate are correct. Direction of rotation is correct. Sump is correctly filled. Compressor servicing is up to date. Electrical supply is correct. If fault appears immediately or shortly after a service, first examine those parts disturbed during the service.

SECTION 5 MAINTENANCE AND REPAIR WARNING BEFORE PROCEEDING WITH MAINTENANCE ON THE COMPRESSOR IT MUST BE STOPPED ISOLATED ELECTRICALLY AND MECHANICALLY, COMPRESSOR GAS INLET AND OUTLET VALVES CLOSED AND VISIBLE WARNING NOTICES DISPLAYED. IN ADDITION ALL INTERNAL PRESSURE MUST BE RELEASED WITH THE UNIT ISOLATED FROM THE SUPPLY AND STORAGE RESERVOIR AND THE WATER SUPPLY SHUT OFF. Note: An O&M manual must cater for a wide variety of operating duties, ambient conditions and methods of control. The following maintenance schedules are only a recommended guide to maintenance periods. It may be found advantageous or desirable to vary the maintenance periods depending on operating conditions and experience.

5.1 5.1.1

MAINTENANCE GENERAL It is useful to record stage pressure, temperatures, oil used in a log against hour’s run, as this builds up a detailed record of machine condition. It can also provide a trend and indication of a possible problem. Do not re-use O rings, seals and joints – fit new! Grease O rings used for all ‘dry’ joints in contact gas. Use a liberal smear of silicone for all O rings st nd used in possible contact with the cooling water. I.e. cooler assemblies, 1 and 2 stage ‘wet’ cylinder liners. Flush out water passages either with high-pressure water or steam cleaning. Clean thoroughly all oil-ways and carefully blow clean using compressed air. Lightly grease or oil all surfaces of ferrous components after cleaning to prevent rusting. Where practical, remove carbon deposits by gently tapping and scraping, taking care not to remove metal.

5.1.2

DAILY Check oil level in crankcase and top up as necessary. Check stage pressures, oil pressure and temperatures.

5.1.3

WEEKLY Check bursting disc for signs of cracking. Check for oil, gas or water leaks; rectify as necessary. Examine oil in crankcase and ensure that it is not contaminated with condensate. Depending on the degree of contamination, the oil may appear emulsified (creamy in colour) especially if the recommended lubricant is not used. If emulsification takes place the oil must be changed and the crankcase cleaned. This condition is usually visible through the sight glass, oil level indicator and must be rectified immediately. Trace cause of contamination, rectify, and fit new oil filter and refill crankcase with recommended oil. If moisture forms without emulsification, as two separate liquids, condensate may be drained from below the oil by means on the drain plug. The oil level should be replenished accordingly with clean oil. Crankcase oil contamination is often accompanied by increase in sight glass oil level, due to oil being supported by condensate fluid. Check correct operation of all controls.

5.2.1 RUNNING IN FOR FIRST 100 HOURS - READ MAINTENANCE WARNING BEFORE COMMENCING Drain sump, replace oil filter, clean sump & refill with recommended synthetic oil * (see SECTION 1.2.4) Clean suction and delivery valves. All components on these compressors are compatible with the recommended synthetic oil but as problems may exist with downstream ancillary equipment, the equipment manufacturer should be consulted. METHOD Drain the oil completely from compressor whilst the oil remains warm. Remove crankcase doors and thoroughly clean interior of the crankcase. Clean oil suction strainer. Renew oil filter. Remove, thoroughly clean and refit all suction and delivery valves. When inspecting valves, also remove as far as is possible any carbon deposit in valve pockets, passageway pipes and separators. Replace crankcase doors and refill crankcase to correct levels with recommended synthetic oil.

SERVICING COMPRESSOR STAGE VALVES

SEE SECTION 6 FOR ILLUSTRATIONS- READ MAINTENANCE WARNING BEFORE COMMENCING 5.4.1 GENERAL Valve maintenance is a simple procedure but the following guidelines should be observed: Keep a spare oiled and maintained set of valve units in store for quick compressor servicing. Valves, when removed, may have only a thin carbon layer and be slightly moist with oil. Note: Unless replacement of the springs and plates is intended, the order in which these components are removed should be carefully noted so that the valves may be reassembled with the same seating faces in contact.

5.4.2

ROUTINE CLEANING AND INSPECTION - ALL STAGES May be removed scraping with a soft, blunt instrument, e.g. a piece of wood. WARNING: Great care should be taken when removing carbon deposits to ensure that the seating faces of the valve components are not damaged. These faces should be clean and bright over their whole area, with no evidence of uneven contact. Renew any plates which are indented, cracked, warped, or have wear grooves which exceed 10% of the plate thickness. Valve plates and springs must always be replaced at recommended life periods, regardless of appearance, to achieve maximum reliability. If the seats show severe wear or indentations, the complete valve assembly must be renewed. The remaining components should be checked for cracks, distortion or other damage liable to impair the valve operation.

5.4.3

ROUTINE VALVE REMOVAL AND SERVICING Valve removal is as follows for all stages: (Special tools that are available from CompAir UK Ltd Ipswich will assist in valve removal) Clean all grease and dirt from valve covers and surrounding areas. Rotate crankshaft by hand until relevant stage piston is at top dead centre. Remove valve covers nuts. Use forcing screws to remove valve covers. Using the special valve lifting tools, remove valve assemblies. A gentle rocking action pulling at the same time will free the valve from any carbon build up in the pocket. Carefully wipe any loose carbon from valve pocket ensuring that no carbon is left in valve pocket or on top of the piston. Move valve to a workbench and remove central nut from valve unit. Carefully separate upper and lower bodies and, with unit on a level surface, lift off upper body. Remove valve plates and springs, noting very carefully their relative positions to the body and each other if they are to be re-used.

Page 44

1293-5.doc 04/09/02

CompAir UK Ltd PUBLICATION 98407/1293 Section 5 Page 45

5.4.4

ROUTINE VALVE CLEANING Completely clean all components as detailed in "Cleaning and Inspection - All stages", Section 5.5.2 Always renew valve plates and springs in complete sets. The seating faces of each valve plate and body half should be clean and bright with all round, even contact and be free from indentations. Any item with indentations will require renewal. Reassemble valve plates and springs exactly as dismantled. NEVER reverse plates / springs as this will lead to rapid failure.

ROUTINE VALVE REPLACEMENT Recheck that valve / valve pocket, top of piston, and the surrounding area is clean before replacing valve assembly. Ensure valve seats properly as a slight misfit will entail loss of gas. Again check valve cover for cleanliness before assembly. Renew "O" rings, lightly greasing before fitting. There should be at least a 2mm (0.80”) gap between the top of cylinder and bottom of valve cover. Sequentially tighten cover fasteners evenly to 75% and then 100% the correct torque, except for fourth stage valve cover; tighten these nuts sequentially in 27Nm (37 lb.ft) steps to the correct torque.

FIRST STAGE VALVE REASSEMBLY - SECTION 6 PAGE 68 Place delivery valve seat (10) face downwards on suitable metal ring, or protected open vice jaws with locating pegs uppermost, position spring plates (3) to located over pegs (9) with bridging strip resting between pegs and springs facing upwards. Place valve plate (2) onto spring plate, located as above, ensuring concentricity on centre hole. Place middle lift washer (7) over hole. Place valve plate (6) onto locating pegs (8). Put lower lift washer (7) onto locating pegs. Place valve spring plates (4) onto locating pegs (8) with springs pointing downwards. Place suction valve seat (1) onto assembly, ensuring inner (8) and outer pegs (9) engage correctly. If assembly has been carried out correctly, upper and lower body faces will contact. Screw nut (12) on stud and hand tighten only at this stage. Test for correct operation by ensuring free movement of suction and delivery valve plates. This is facilitated by gently pushing a small diameter plastic or nylon rod through the ports in the valve to check plates for freedom. If satisfactory tighten to the correct torque. If plates are not free, dismantle, relocate misplaced part and assemble, check again for free movement of plates before tightening to the correct torque. Ensure "O" ring (11) is secure in slot in upper valve body.

5.4.7

SECOND STAGE VALVE REASSEMBLY- SECTION 6 PAGE 69 Place delivery valve seat (8) face downwards on suitable metal ring or protected open vice jaws with locating peg (7) uppermost and position valve plate (6) to locate over peg (7). Fit spring plates (5) onto valve plate, locating them on peg (7), springs facing downwards. Follow this with valve backing plate (4). Place delivery valve springs (3) onto valve / backing plate having first positioned them as follows: Assemble the delivery plate springs (3) in pairs, rotating one spring in each pair until the inner and outer circumferences are matched perfectly. Hold the two springs together with the concave faces facing each other and then rotate one pair until edges touch all round the circumference and there is a constant gap around the inner edge. Place valve plate (2) on spring plates and then after ensuring concentricity place suction valve seat (1) onto assembly. If all components are located correctly upper and lower bodies will contact. Screw nut (10) on stud and hand tighten only at this stage. Test for correct operation by ensuring free movement of suction and delivery valve plates. This is facilitated by gently pushing a small diameter plastic or nylon rod through the ports in the valve to check plates for freedom. If satisfactory tighten to the correct torque. If plates are not free, dismantle; relocate misplaced part and reassemble, checking again for free movement of plates before tightening to the correct torque. Ensure "O" ring (9) is secure in slot in upper valve body.

MAIN-END BEARINGS Use a hydraulic press to remove old bearings from bearing housings.

5.6.8

BIG-END BEARINGS - MEASURING BEARING CLEARANCES Remove crankcase doors and remove all big end caps. Measure crankshaft journals in two positions at 90° for each big end. If any one dimension is below the minimum given in Section 1.4 it is recommended the compressor be overhauled. Do NOT merely fit new bearing shells. If satisfactory refit big end bearings, ensuring identity numbers are adjacent and facing upwards. Note: The big end bearings fitted to the connecting rods are of the aluminium / tin line overlay, steel backed shell type, on an underlying copper based bearing material. It is important to note that due to the bedding process, which occurs during running-in, that the aluminium / tin overlay will be removed in the areas of highest load exposing the underlying copper based bearing material. This is quite normal and does not indicate a fault in the bearing or the need for shell replacement. After initial bedding in to this level the bearing will show no significant further change for several thousand hours. When aluminium / tin lining overlay has been removed from an area greater than 90% of the bearing surface of either top or bottom half bearing shell, the complete bearing must be replaced.

5.6.9

SMALL-END BEARINGS st Note: The 1 stage bearing is a plain bush, NOT a rolling contact needle roller bearing. If there is detectable movement of the piston or crosshead at 90° to its normal plane of movement of the conn-rod, remove and discard the gudgeon pin and needle roller bearing. Note the needle rollers may dislodge from their holder when dismantling, care must be taken when refitting gudgeon pin.

ADJUSTMENT METHOD If the belt tension is incorrect, correct it by using the adjusting screw provided, using a suitable straight edge (long enough to span both pulleys),.established the correct deflection and pulley alignment.

Belt Section Belt Section SPB SPB SPC SPC

TABLE Force required to deflect belt 16 mm per metre of span Small Pulley Ø mm 160 to 224 224 to 315 224 to 355 375 to 560

Newton (N) 35 to 50 50 to 65 60 to 90 90 to 120

Kilogram force (kgf) 3.5 to 5.1 5.1 to 6.6 6.1 to 9.2 9.2 to 12.2

Method of Belt Tensioning. Using a Belt Tension Indicator. 1.

Measure small pulley diameter (motor/engine)

2.

Calculate the deflection distance in mm on a basis of 16 mm per metre of span. Centre distance (metres) X 16 = Deflection (mm). If distance & deflection is known, go to 3.

3.

Set the lower marker ring at the deflection distance required in mm on the lower scale.

4.

Set the upper marker ring against the bottom edge of the top tube.

5.

Place the belt tension indicator on top of the belt at the centre of span and apply a force at right angles to the belt deflecting it to the point where the lower marker ring is level with the adjacent belt, on single belt drives place a straight edge across the two pulleys to act as a datum.

6.

Read off the force value indicated by the top edge of the upper marker ring.

7.

Compare this force to kgf value shown in the table above.

8.

Tighten or loosen belt tensioner to achieve the correct value.

9.

If the measured force falls within the values given, the drive should be satisfactory.

Note:- If a belt tension indicator is not available, a suitably scaled spring balance and rule will suffice. BELT TENSION INDICATOR

-

0.5 bar

Ensure fan/vee belt guards are always fitted before operating compressor. 1.

2.

FILLING COOLING SYSTEM 1.

Remove radiator filler cap and fill the system with clean water. TOTAL CAPACITY OF SYSTEM IS APPROXIMATELY 22 GALLONS (100 LITRES).

2.

Replace filler cap.

3.

Start compressor run for a few minutes to pump water through the system.

4.

Shut down compressor.

5.

Remove radiator filler cap and top up system if necessary.

6.

Once the compressor is filled it is only necessary to periodically top up the radiator.

COLD WEATHER PRECAUTIONS 1.

3.

4.

Page 4

In freezing conditions ant-freeze (recommended type:- Ethlene glycol (ethanediol) should be added to the cooling system. Use quantities recommended by the anti-freeze manufacturer.

MAINTENANCE 1.

Very little maintenance is required as the strong airflow and flat fins minimize any fouling tendencies.

2.

DO NOT remove grease and dirt with the use of TRICHLORETHYLENE.

3.

Check periodically for leaks from pipe connections, which could result from excessive mechanical or hydraulic vibration. Tighten or renew joints as necessary.

4.

Drain and flush through and replenish cooling system every 2 years. More often in a high contaminating hard water area.

RADIATOR FAN MAINTENANCE 1.

Periodically check security of fan hub attachment to shaft.

2.

Check security-fixing screws of blades to hub.

3.

Ensure blades are clean and there is no build-up of dirt and grime, as this will cause out of balance loading and subsequent vibration on the motor shaft.

ELECTRIC MOTOR MAINTENANCE WARNING : Isolate power supply to motor before commencing any routine cleaning or maintenance work. Routine Cleaning : Remove the fan cover and ensure that all holes are completely open. Clear any dirt and fluff from behind the fan and along the ribs of the frame.. Periodic Maintenance : Remove the cover and the fan which is fitted on the shaft extension. Slacken and remove bearing cover screws and endshield bolts/studs. The endshields should then be eased off their spigots. The rotor can now be withdrawn carefully from the stator. Having dismantled the motor, maintenance can now be carried out to remove all dirt. Dry, compressed air under comparatively low pressure is best as a high velocity stream can force dirt into the spaces between windings, etc. Grease removing solvents should only be used very sparingly so as not to damage impregnating varnish or insulation. Bearings are charged with sufficient grease to last at least two years, provided there is little or no grease leakage. When replenishing, use only good quality lithium based grease and avoid overfilling the bearing housing. Motors should be reassembled in the reverse order from dismantling, taking care not to damage the windings on insertion of rotor, taking care not to damage the windings on insertion of rotor, remembering to ease endshields on bearings and spigots. DO NOT USE FORCE. Before starting, check that the rotor revolves freely. Ensure that the electrical connections are correct and terminal nuts tight. Refit any pulley, coupling, sprocket etc. which have been removed, being particularly careful to ensure correct alignment with the driven part, as misalignment may lead to ultimate bearing failure and shaft breakage.

CompAir UK Ltd PUBLICATION APP070 PRESSURE GAUGES GENERAL Page 1

PRESSURE GAUGES GENERAL The pressure gauge should be installed such as to avoid exposure to heat and vibration and to enable easy observation of the dial indication. IMPORTANT It is common practise to install the pressure gauge without an isolating device, so to facilitate calibration or replacement the system must be de pressurised before any work is carried out. The pressure gauge is liquid filled to provide better damping from pulsation’s. INSTALLATION & COMMISSIONING The tightening and loosening of torque applied to the connection should be by means of the spanner flats provided on the stem and should not be by means of grasping the case as this may damage the gauge. No pressure higher than indicated by the working pressure symbol ▼ must be applied to the gauge during hydrostatic pressure testing of the system. Otherwise the gauge must be isolated or removed during this operation. No attempt should be made to remove a pressurised gauge. The pressure system must be totally relieved if the gauge can not be isolated otherwise. The remainder of the pressure medium contained in the element may be hazardous or toxic. This should be considered when handling and storing the removed pressure gauge.

PRESSURE GAUGES IN SERVICE. Always open isolating devices always gently and never abruptly, as this may generate sudden pressure surges that may damage the gauge. The maximum working pressure for which the gauge is suitable, or also the minimum working pressure in cases of vacuum, is indicated on the dial by corresponding marks ▼. Fluctuating pressure always reduces the maximum working pressure of the gauge. Correct zeroing may be inspected by closing the isolating valve and relieving the gauge from pressure. The pointer must fall within the thickened portion of the zero mark. Unless the gauge temperature is considerably higher or lower than 20°C, a pointer not returning to zero may indicate serious damage to the gauge. On-site testing of the pressure gauge is feasible by means of special isolating devices enabling connection of a test gauge together with a suitable pressure source.

CompAir UK Ltd APP 081 PRESSURE SWITCH 98524.1004 Page 1

PRESSURE SWITCH 98524/1004 OPERATION Located as close as possible to the H.P. delivery line, the pressure switch stops the compressor when the upper pressure limit is attained and triggers off the start when the lower limit is reached. The switch transforms a change of pressure into an electrical 'On' or 'Off' signal. When a pre-set pressure is reached the snap action contact changes state.

INSTALLATION Pressure switches may be mounted in any convenient position close to the H.P. line, provided it is not subject to vibration and that the connecting pipe to the receiver does not exceed five metres. Mount the switch by the lugs provided on the casing. Where possible the pressure switch operating line should be taken from the receiver to avoid pressure oscillations. It is usual to connect 1 and 2 to the compressor electrical control circuit terminals marked pressure switch'.

Set pressures: 98524/1049 Setting Range 2 - 42 bar g rising Set Pressure HIGH 31 bar g rising Set Pressure LOW 28 bar g falling. 98524/1104 Setting Range 2 - 70 bar g rising Set Pressure HIGH 40 bar g rising Set Pressure LOW 36 bar g falling. 98524/1137 Setting Range 3 - 66.5 bar g rising Set Pressure HIGH 42 bar g rising Set Pressure LOW 39 bar g falling. The switch transforms a change of pressure into an electrical "On" or "Off" signal. When a pre-set high pressure is reached the snap action contact stops the compressor, after dropping to the lower setting, the compressor restarts. ADJUSTING NUT CONDUIT THREAD

INSTALLATION Mount the switch by the bracket provided. It is usual to connect 1 (C) and 2 (NC) to the compressor electrical control circuit terminals marked "Pressure Switch".

Installation and Operating Instructions SAFETY VALVES INTRODUCTION Due consideration should be taken of climatic. Process or other conditions which might adversely affect the performance of the safety valve. Installation must be undertaken by qualified technicians and to good engineering practice. In addition, user's attention is drawn to our joint responsibility to ensure that the Health and Safety at Work Act is not contravened by incorrect installation. Commissioning or servicing. It is important that the valve to be installed is correct in every aspect, i.e. set pressure, size, material and type etc. for the application.

STORAGE OF VALVE BEFORE INSTALLATION Valves should be stored preferably between-5°C and +25°C and a relative humidity of less that 75%. Very moist or dry conditions should be avoided. If a safety valve is installed after six months, or more, of storage, it must be subjected to functional test before commissioning. Thread protectors should not be removed until immediately, prior to testing or installation, as they also prevent the ingress of foreign matter, which could harm the valve.

INSTALLATION VALVE INLET: Under no circumstances should it be possible to isolate the safety valve from the protected system. Safety valves should be mounted as close as possible to the protected system. The connecting pipe should be straight and as short as possible. The inlet line to the safety valve should have an effective area of flow, at least equal to that of the safety valve inlet. CompAir Limited should be consulted if the safety valve is to be mounted in any position other than vertically. The maximum pressure drop through the inlet line to the safety valve should not exceed 3% of the set pressure when the valve is discharging at its rated capacity. VALVE OUTLET: No isolating devices shall be fitted to the outlet pipe. Discharge pipes should be as short as possible and of such a size that the pressure developed therein not reduce the relieving capacity. Ensure arrows indicating the direction of the flow are pointing in the correct direction. The cross-sectional area of the discharge pipe should not be less than the area of the safety valve outlet. Where safety valves are discharged into a manifold, the manifold must be capable of accommodating simultaneous discharge of all valves connected to the manifold. Atmospheric discharge or discharge pipes should terminate at a location which will not cause a hazard to personnel, particular attention being given to hazardous fluids or particles. GENERAL: Inlet and outlet piping should be capable of supporting the safety, valve so that no unacceptable mechanical load or vibration is transmitted to the valve, and be sufficiently strong to withstand 'the effects of the reaction forces when the valve is discharging. All pipework or pressure vessels to which the safety valve is connected should be thoroughly cleaned before fitting the safety valve, to ensure that foreign matter does not pass through the valve. Particular care should be taken with the use of scaling compounds and P.T.F.E. tape to ensure that they do not enter the valve. Atmospheric discharge valves should not be painted or coated with any substance, which could possibly obstruct or restrict free and full discharge through the valve. Suitable protection should be provided to prevent environmental build up or ingress of foreign matter. Any condition that could lead to blockage of discharge piping or discharge ports on safety valves must be avoided. Where appropriate, discharge pipes should be provided to a non-hazardous location. Where there is a possibility of a liquid head forming in a discharge pipe, a drain should be provided which leads to a safe discharge location. To prevent unnecessary lifting of the safety valve it is recommended that there is a margin of at least 10% between the maximum operating pressure and the set pressure of the safety valve. FUNCTIONAL TESTING Once installed in service. Valves should be tested at least once every six months to ensure free movement of parts. This should be carried out by operating the easing gear when the valve is under a pressure of not less than 75'% of the set pressure. Where valves are supplied without easing gear, the test should be in accordance with the full functional test described overleaf. Due regard must be paid to the safety personnel. Testing should not create a hazard, particular attention being given to foreign matter located in discharge outlets.

PRESSURE MAINTAINING VALVE U572/B This valve is fitted to maintain a back pressure through the separators, filters and the dryers (if fitted). This ensures that these items of equipment reach their optimum working pressure as soon as possible, to give long filter life, good oil separation and low oil consumption.
