CHAPTER 1 - TECHNICAL DATA & COMPRESSOR DESCRIPTION 1.2.3 Compressor Operation
The compressor operates by drawing air from atmosphere via an efficient air filter and silencer system into the 1st stage cylinder where it is compressed to approximately 3 Bar G. The heat generated by compressing the air is dissipated in the water-cooled intercooler, positioned after the 1st stage cylinder. The cooled air then flows through the 2nd stage suction separator, which removes any moisture condensed during cooling. The air then passes to the 2nd stage cylinder where the air is further compressed to approximately 11 Bar G. The heat generated by compressing the air is dissipated in a water-cooled intercooler, positioned after the 2nd stage cylinder. The cooled air then flows through the 3rd stage suction separator, which removes any moisture condensed during cooling. The air then passes to the 3rd stage cylinder where the air is further compressed to its final delivery pressure of 45 Bar G (max). The heat from compression is dissipated in the water-cooled aftercooler positioned after the 3rd stage cylinder. The cooled air then flows through the final delivery separator, which removes any moisture condensed during cooling. The compressed cool dry air is then discharged into the delivery pipework. 1.2.4 Crankcase and Lower Motion Work Crankcase The crankcase is a heavily-ribbed iron casting with integral mounting feet and cylinder mounting flanges. Also integral within the crankcase are housings for the two crankshaft drive-end bearings. There are machined faces for the flange mounted motor, bearing end cover, crankcase and main guide doors. The bolt-on bearing end cover incorporates the housing for the third crankshaft bearing. The crankcase forms the lubricating oil sump, and is complete with tapped holes for the oil level window nut, the oil pump suction feed pipe, the crankcase drain plug and the oil cooler. Oil retention in the crankcase is made possible by a lip seal fitted at the drive-end of the crankshaft and by scraper rings fitted around the piston rods. Immediately beneath the drive-end crankshaft seal housing is an integral oil return passage. The single throw, cast high-tensile iron, crankshaft has integral design counterbalanced weights. The standard throw is 82.55 mm, giving a piston stroke of 165.10 mm. The crankshaft is supported by three self-aligning, double-race spherical roller bearings, two at the driving end and one at the oil-pump end. Endwise location is by clamping the outer drive-end main bearing (in the oil seal holding cover) against a machined shoulder in the crankcase. The driving end has a tapered shaft which is keyed to accommodate the rotor of a direct mounted motor. The oil pump end of the crankshaft has internal oil passages to the crankpin. Oil Pump The gear type oil pump is mounted on the crankshaft bearing end cover and is driven via a coupling off the non-drive end of the crankshaft. Oil is drawn by the pump from the crankcase sump through a wire mesh strainer and external pipe. The oil is delivered through a full-flow fine-mesh cartridge filter to the oil ways in the crankshaft. Any excess oil output is by-passed back to the sump by a spring-loaded pressure relief valve mounted on the crankcase main bearing housing. All the bearing surfaces in the crankcase are lubricated by the oil passing through the bore of the crankshaft and connecting rods. The main roller bearings are splash lubed by the oil from the crosshead, and also by the general oil mist in the crankcase.

CHAPTER 1 - TECHNICAL DATA & COMPRESSOR DESCRIPTION Connecting Rods
The connecting rods have detachable bottom end caps to facilitate removal of the rods and rods have split-shell bottom end bearings and bush type top end bearings. The bottom end bearing shells are steel backed copper-lead, lead-tin plated. The pressedin top end bushes are lead bronze. An oil passage connects the top and bottom bearings allowing oil under pressure (from the oil pump via passages in the crankshaft) to lubricate both. Oil is sprayed, from an annular groove around the top end bush and through two small holes, onto both slides of the crosshead guide. Crossheads The crossheads run in the main guides which are bolted to the cylinder mounting flanges of the crankcase. The crossheads are attached to the top of the connecting rods by gudgeon pins (which are retained themselves by circlips). The top face of the crosshead is drilled and tapped for reception of the piston rod. The piston rod is retained by a securing pin which passes through the side of the crosshead into the slot in the end of the piston rod. The piston rod is then clamped by a nut, which is tightened down against the top of the crosshead. The securing pin is prevented from coming loose by a retaining plate.

CHAPTER 1 - TECHNICAL DATA & COMPRESSOR DESCRIPTION 1.2.5 Cylinders, Pistons and Piston Rod Packings Cylinders
The double-jacketed cylinders are cast complete with mounting base, lower valve chambers and housing for piston rod packing assembly. They have machined faces for the top cover; lower mating flange, valve covers, distance rings and valves, and air and water inlets and outlets. The inner jacket of the cylinder is for the cooling water, the outer jacket is divided into suction and delivery air chambers. The cylinder top covers are cast with integral valve chambers, cooling water passages and suction and delivery air chambers. They have machined faces for the cylinder joint, valve covers, distance rings and valves. The cylinders are non-lubricated, the piston rings being made of low friction material, and are spaced off the crankcase by distance pieces containing oil scraper packings. These prevent oil from the crankcase sump getting into the cylinders. Cooling is provided by passing water first through the compressor intercoolers, and then, via a series of pipes, around the compressor cylinder water jackets and cylinder top covers. Pistons and Rings The 1st & 2nd stage pistons are of a two-piece hollow construction with the 3rd stage piston being of solid construction. Each piston is machined with piston-ring grooves with the centre body of each piston drilled and recessed to take the piston rod. Piston Rods and Packings The piston rods are threaded at both ends. The piston rod bottom end has a cruciform slot to accommodate a securing pin (to prevent rotation of the rod in the crosshead) and is held in the crosshead by a locknut. The top end of the rod is shouldered and waisted inside the piston. A self-locking nut secures the piston to the rod. The piston/cylinder end clearances at the top and bottom are governed by the distance the piston rod is screwed into the crosshead. The oil-free cylinder compressor has separate packing gland assemblies. The packing comprises multiple pairs of PTFE rings, each pair of rings being housed in a container and held against the piston rod by a garter spring. The containers are assembled to a base by long studs and nuts, and the assembly held in its housing in the base of the cylinder by studs and nuts. A soft iron ring is recessed into the top surface of the upper container to prevent air leakage around the packing. The separate scraper assembly is housed in the crosshead-guide loose plate and comprises a number of segmented rings in a split casing, each ring is held in contact with the piston rod by a garter spring. An oil shedder is also fitted to the piston rod between the packing and the scraper assemblies to prevent any oil-creep along the rod.

CHAPTER 1 - TECHNICAL DATA & COMPRESSOR DESCRIPTION 1.2.6 Valves
Suction and delivery valves are similar in construction but differ in detail. Care must always be taken when servicing the compressor to ensure that the correct valve is fitted into the correct valve chamber. All suction valves are controlled by plate depressors (or unloaders), their location being identified by the presence of actuators on the valve covers. The actuators have small bore instrument air pipes connected to them. To unload a working compressor. the suction valves are rendered inoperative by the valve plates being pressed off their seats. This is accomplished by plate depressors (unloaders) being operated by load control actuators. A plate depressor is basically an inverted cup-shaped body with fingers protruding from its rim, assembled with a spring-loaded central guide surmounted by a cylindrical cap. The fingers operate through slots in the suction valve seat directly onto the valve plate. In action the plate is depressed, against its spring, by the pneumatically operated actuator. Compressed air fed to the load control actuator, by the load control solenoid valve, acts on a multi-layer diaphragm, which is sandwiched between the two halves of the actuator body. The diaphragm is in contact with the head of the spring loaded plunger immediately under the disk. The plunger, guided in the lower half of the actuator body, has its stem end in contact with the cap of the plate depressors. When the control air is exhausted by the solenoid valve, springs return the plunger away from the valve plate. 1.2.7 Motor and Couplings The compressor can be supplied with a flange-mounted motor, or as a bare-shaft machine. The standard motor is a brush-less cage rotor type, with a power output suited to the delivery requirements of the compressor. The motor's rotor is keyed directly onto the crankshaft and the stator casing is bolted to the crankcase. 1.2.8 Control Panel and Controls The compressor can be supplied with or without a starter system. The standard starter system is housed in a two-compartment dust and damp proof wall or floor mounted sheet steel cubicle. The control panel is an integral part of the front of the cubicle and the controls and gauges are divided between the upper and lower compartments. (For full details of the controls their operation and functions refer to the supplementary information provided with your compressor).

CHAPTER 2 - SAFETY INFORMATION 2.1.3 Organisational Measures
It is the customer’s responsibility to ensure that the operating manual is adequately supplemented with internal regulations regarding supervision and notification duties, work organisation, and personnel qualification etc. No modifications may be carried out on the compressor or its peripheral devices without the written consent of Gardner Denver Belliss & Morcom. Unauthorised Modification of the equipment will invalidate the WARRANTY. When renewing compressor components use only original spare parts and accessories supplied by Gardner Denver Belliss & Morcom. 2.1.4 General Safety Precautions for Compressors Electrical System - Before performing work on the electrical system the compressor and the peripheral devices must be isolated form the mains and secured against switching on accidentally. Work on the electrical system must only be carried out by qualified staff who are aware of the risk involved with the task. Pressure Relief Valves - These MUST be Full Compressor Capacity relief valves connected directly to the flow pipework to relieve any excess pressure that may buildup between the cylinder discharge flange and in line equipment (e.g., stop valve, nonreturn valve, cooler, etc).
WARNING! It is forbidden to operate the compressor unless all relief valves are correctly fitted, in fully operational condition and are set at the correct relief pressure for the compressor duty. There must be no restriction of any kind between the relief valve position and the preceding cylinder. Relief valves must be directly mounted with no isolating valves interposed between the relief valve and the pressure sensing point. The exhaust from the relief valves must only discharge into designated safe areas. The setting of relief valves must be checked regularly as required by statutory codes and regulations. Pressure vessels must be fitted with a full capacity pressure relief valve. Vessels must not be operated above their stated operation rating and must be checked regularly as required by codes and regulations. Protection Equipment - All protection, control switches and circuits must be regularly checked for correct operation. Switches can be tested by checking in calibration rigs, or by carefully controlled simulation of fault conditions at the actual machine. Circuits can be checked by mechanically operating the switches. Frost Protection - Where, due to its location, the compressor could be exposed to frost, then adequate precautions must be taken to prevent freezing of the water system. Guards - All guards and covers must be in position and secure before start-up.

CHAPTER 2 - SAFETY INFORMATION
Operating Records - It is IMPORTANT that a regular log sheet be kept for the compressor recording operating pressures, temperatures and oil pressure (a copy of a Log Sheet is provided within the Appendices located at the end of this manual). Variances from normal running performance should be brought to the immediate attention of the Supervisor responsible for consideration and action. Lifting Equipment - Before using any lifting equipment, it is IMPORTANT that the crane, gantry, hoist or chain block and any slings employed must be certified capable of lifting the weight of the compressor (or motor/compressor assembly). Any such lifting equipment MUST have a current CITB Test Certificate (or an equivalent certificate applicable to the country of installation). 2.1.5 Installation, Commissioning and Operation In all matters of safety regarding the Installation, Commissioning and Operation of the compressor or package, the reader's attention is directed to the full implementation of the requirements of the Health & Safety at Work Act (and any such regulation applicable in the country of installation). Gardner Denver Belliss & Morcom may be consulted should any doubt exist regarding matters of safety related to their product. 2.1.6 Maintenance In addition to the General Safety Precautions, the following safety precautions MUST be observed when maintaining your machine. 1)
Before commencing any maintenance work on the compressor or its driving unit or any ancillary, the driving unit must be rendered incapable of being started whilst maintenance and adjustment work is in progress. In the case of an electric motor for example, the machine must be isolated from the main electricity supply, the isolator locked off and/or the fuses withdrawn. This is particularly important with auto start/stop machines where the machine could be started automatically.
2) 3) 4) 5) 6) 7) 8) 9) 10)
Affix "NOT TO BE USED" boards to the compressor and control cabinet. Isolate the compressor from the discharge main and the instrument air. Before opening up the machine, all pressurised compartments MUST be depressurised down to atmospheric pressure in a safe and controlled manner. Isolate the compressor from the cooling water supply and drain all relevant water containing compartments. If the compressor motion work or rotational parts are to be worked on then piston rod clamps MUST be fitted to prevent accidental movement. Also chocking the crankshaft should be considered where necessary. ALL lifting equipment MUST be correctly rated for the loads being applied and MUST be certified as being in good working condition. Always ensure that when lifting equipment is used, only specified lifting or slinging points are used. Always refer to the applicable procedure when undertaking maintenance and overhaul procedures. Bolts and nuts must not be under or over tightened, see appropriate torque values in Chapter 1 Section 1.1.3. Ensure that ALL tools and spare parts are accounted for after reassembly, since any items left on or within the compressor may cause serious damage upon restarting.

INSTALLATION & COMMISSIONING
3.1 Safety Precautions Before carrying out any work related to this Section, it is a requirement that you read and work in accordance with, the Safety Precautions given in Chapter 2 of this manual. For your own protection, be sure to read and obey the WARNING and CAUTION notices you find in this Section and any associated literature.
WARNING! 1) If the compressor is to be supported on anti-vibration mountings, air, water and electrical services are to be made with non-rigid (flexible) connections. 2) Due to possible electrical insulation effects of pipe gasket
material and anti-vibration mountings, the machine must be provided with a permanent earth continuity connection of a nonrigid (flexible) type, which should comply with local regulations and safety requirements.
3.2 Installation Requirements The installation of the compressor, and its associated pipework, should be the subject of careful consideration before undertaking the actual task. This section of the manual provides the necessary information for the installation engineer to locate and to install the compressor to the best advantage. 3.2.1 Location The compressor should be located in a clean, well-lit, well-ventilated area with ample space all around it to facilitate inspection and maintenance. Sufficient room must be allowed for the removal of pistons and cylinders, crankshaft and motor, and as the compressor and many of its components are heavy, there must be headroom sufficient to permit the operation of a crane or hoist, which must be certified capable of lifting safely the weight. Statutory regulations and local by-laws governing the operation of heavy machinery must be complied with, this may have some influence on the choice of location. 3.2.2 Ventilation Approximately 10% of the energy consumed by a compressor is lost as heat. This is the heat generated by the motor, the mechanical losses of the compressor and straight-forward heat radiation from the air manifolds. For example, a 365kW water-cooled compressor would require some 486 m3/min of ambient air circulation to limit the compressor room temperature rise to 6ºC. Natural convection is normally adequate with the outlet vents at a high level to prevent the temperature building down from the roof.

CHAPTER 3 - INSTALLATION & COMMISSIONING 3.2.3 Foundations
For vibration isolator mounted compressors, all that is required is a floor of sufficient strength to carry the weight of the compressor, motor and ancillaries. For solidly mounted compressors the foundation dimensions must be determined for each installation, consideration being given to the nature of the subsoil and local surroundings.
WARNING! The floor must be level and flat.
Foundation depth must be such that the subsoil reached is, in the opinion of an expert, capable of taking the load of the working compressor and preventing the transmission of vibration. Unless the foundation rests on bed-rock or hard-pan, a sub-footing should be made of such a size and design as to provide a solid bottom. In extreme cases of poor subsoil, piling may be required, and in such circumstances a competent foundation engineer should be consulted. If the compressor is to be mounted on a metal floor, it can be either bolted direct to the floor, or beam or skid mounted. The beams or skids may be bolted or welded to the floor, with due consideration being given to structural vibrations and floor strength. A foundation plan (for good subsoil conditions) is furnished in advance of the shipment of the compressor, and the foundation used must not be less than given in the plan. When installing a solidly mounted compressor, it must be ensured that the crankcase feet are ALL flat down and fully supported BEFORE tightening the "Holding Down" fasteners. A detailed foundation drawing is available (on request) from Gardner Denver Belliss & Morcom. 3.2.4 Pipework Installation These paragraphs give recommendations with regard to both suction and delivery pipework and will help the plant engineer plan the best possible installation. Pipes must not be fixed inflexibly such that heavy thrust can act back onto the compressor otherwise serious damage could result, examine carefully the anchoring point locations and pipework support arrangements.
WARNING! All inlet and outlet connections to compressors mounted on vibration isolators MUST use suitable flexible pipes. All flexible pipes MUST be installed in accordance with the manufacturer's instructions. Inlet System An efficient air intake filtration system is essential to ensure that debris is removed from the air flow to the compressor thereby prolonging the life of the machine. Standard Gardner Denver Belliss & Morcom practice is to fit a machine mounted, combined filter/silencer, however, in hot or dirty locations, or in the presence of difficult combinations (e.g. fumes, alumina or cement dust), filtration may be improved by mounted the intake remotely and ducting the air to the compressor. Special filter/silencer arrangements are available for this type of installation. Only dry type filters must be used with oil-free compressors. Noise regulations should be taken into account when deciding silencer requirements and locations.

CHAPTER 3 - INSTALLATION & COMMISSIONING Delivery System
The flexible delivery pipe connects the aftercooler to the receiver (where fitted). It must be of the correct specification for the pressure and temperature and nature of the medium being compressed, and not smaller than the size specified below.
'X' and 'Y' dimensions for standard units are usually identical but these can be unequal to suit specific installations. Whatever dimensions apply at x and y, this instruction remains totally applicable. For new pipes, x and y are maintained by the presence of "Tie-Bars" to ensure correct installation. Once installed, the Tie-Bars must be removed before the machine is operated. Hose must be mounted in the position shown above, where one leg is completely horizontal and the other completely vertical and fully supported at its connection: no other position is allowable. When fitted statically, hose must be free of all imposed stresses such as 'torsional', 'distortional', 'compressive', 'tensional' etc. MOVEMENT DURING RUNNING (A)
During start-up only:
Frequency up to 12.5 Hz. 20 mm movement in any plane 0.5º about any axis
(B)
During normal running
Frequency up to 25 Hz. < 3 mm movement in any plane < 0.25º about any axis
The pipe must be well supported to avoid strain on the compressor cylinders, and it's configuration be such that any expansion effect, due to the air/gas temperature rise for whatever reason, can adequately be dissipated within the natural elasticity of the pipework leading from the compressor and cannot act back on the cylinder.

CHAPTER 3 - INSTALLATION & COMMISSIONING
At the junction with the receiver, or pipe main, a shut-off valve should be fitted to isolate the compressor as required. On automatic and multi-machine installations, non-return valves should also be fitted to isolate standby units from system pressure. A safety valve must be fitted, close to the compressor, in the delivery pipe. The valve must be fitted before any shut-off valve, non-return valve or aftercooler to prevent damage in the event of the compressor being run with the shut-off valve closed. The valve should be a spring-loaded type and of sufficient size to pass safely the maximum compressor output. A small blow-down valve should be fitted between the compressor and shut-off valve to relieve residual pressure when required for maintenance purposes. Air Receiver An air receiver of ample capacity is required for use with this equipment. The receiver should have a capacity equal to a one minute supply of compressed air (neglecting temperature rise). The air receivers should, ideally, be located in the coldest place possible, to ensure that as much condensate as possible is precipitated from the air in the receiver. This means that the receiver must be drained frequently, either by fitting an adequate drain or an automatic drain trap. To facilitate servicing of the drain trap whilst the receiver is in commission, a by-pass should also be incorporated. Distribution Piping (air systems) Water collectors of an automatic discharge type should be fitted at suitable points in the pipe system. They should be fitted with three-way cocks (either in connection with the traps or separately) so that pipes may be blown through to disperse condensation. Delivery pipework must be arranged to prevent condensation running back from the aftercooler or receiver into the compressor cylinders. The pipe system for air distribution should be carefully considered if optimum results are to be obtained. Moisture-laden air can cause rusting in low-lying parts of the pipe system so, ideally, all distribution pipework should be internally galvanized and angled slightly towards the drain points. An effective way of eliminating possible water damage is to install a refrigerative air dryer or, for dryer air, an adsorption dryer.

CHAPTER 3 - INSTALLATION & COMMISSIONING Load Control Piping
Connect (with similar size piping) the load control system on the compressor to the control air take-off points on the compressor panel, the connections on the compressor will indicate the size. Connect (with similar size piping) the compressor panel control air inlet point to the compressed air/instrument air main - any isolating valve fitted here must be of the lockable-open type. Drain Valves & Drain Valve Piping It is important that the drain pipes from the water separator drain traps are run individually to open ends (e.g., over OPEN drains). They must NOT be piped together as there would then be a risk of "blow-back" along adjacent pipes in the event of a trap malfunctioning. Drain valves are fitted to the separators of each compression stage. These valves exhaust the collected moisture at high pressure and must be piped away to a safe area using solid pipework. MOST IMPORTANT - if the exhausts of any vent valves are piped away, it is essential that these have direct outlets to atmosphere, they must NOT be connected into any other pipe. It is also recommended that a silencer is fitted to the exhaust in order to reduce noise levels. 3.2.5 Cooling Water An adequate source of clean, cool water for the compressor cylinders, intercoolers and aftercooler should be provided. Cooling water must be as free as possible from scale forming salts, with (if the water is not clean) an efficient filter(s) placed in the intake pipeline. A Duplex type arrangement is recommended as this will allow one filter to be cleaned whilst the other is in service. The temperature of the cooling water supply to the compressor (NOT aftercooler) should not be less than the ambient temperature. The methods of achieving this depend on the cooling system employed: The temperature of the cooling water supply should be in the range 20ºC to 35ºC In situations where the ambient temperature is in excess of 35ºC., advice should be sought from Gardner Denver Belliss & Morcom. The pressure in the cooling water pipeline at the compressor must be sufficient to promote the flow required by the size and duty of the machine. This should take into consideration all the friction losses in the overall pipework and valves and across the heat exchanger units (as may be installed) as well as across the compressor. Except for compressors made to special customer requirements, water pressure in the jackets should not exceed 7 Bar g.

CHAPTER 3 - INSTALLATION & COMMISSIONING
3.2.5 Cooling Water (Cont) It is recommended that thermometer pockets are fitted to the water inlet and outlet pipes to the compressor and, the aftercooler. Temperature differentials between these points will give a good indication of sufficient water flow, 10 to 12ºC being usual.
CAUTION! Failure of water flow is a cause of major damage and must be avoided. Ensure that cooling water pipes to and from the compressor are constructed to avoid the formation of air locks For compressors operating in cold environments, drain points are present on the cylinders to empty the water jackets of the machine (when out of service) to prevent damage in the case of frost. Open air vent cocks at the tops of the cylinders at the time of water drainage. Certain water pipe connections should afterwards be disconnected to completely drain the system.
CAUTION! Exposure to frost conditions will damage your machine unless the proper frost precautions are taken. If advice is required, please contact Gardner Denver Belliss & Morcom. 3.2.6 Electric Cabling The electric cabling to the motor must be run such that small amounts of movement at the motor terminals can be safely absorbed within inherent flexibility of the type of cabling used. Check that the motor nameplate details agree with those of the electricity supply on which the motor is to be used. Connect motor in accordance with the instruction supplied. Use cables of adequate size to carry the full load current and also large enough to carry the starting current without excessive voltage drop. Ensure that the motor frame is properly earthed.
3.3 Handling and Unpacking 3.3.1 Stability Due consideration must be given to maintaining the compressor's stability during all lifting procedures. The compressor is only in a stable condition when standing on a suitable, level floor surface with all four crankcase feet firmly down. It MUST be noted that the Centre of Gravity (C of G) for each machine will change depending on whether the compressor is 'bare-shaft' or fitted with a 'drive unit'.
WARNING! The crane, gantry, hoist or chain block or any slings employed must be certified capable of lifting the weight of the compressor (or Motor/Compressor assembly).

Compressor Slinging Diagram (Typical)
3.3.2 Slinging Instructions On all compressors two cradle slings are positioned, one under each of the two outer cylinder crankcase flanges. A third sling is used to balance the compressor. a. b. c.
In the case of a compressor fitted with a flange mounted motor, a cradle sling is passed under the motor, taking care to keep it clear of the fan housing. In the case of a bare shaft compressor, a sling is passed round the intercooler pipework. If the compressor is fitted with a flywheel, a balancing sling is passed around the shaft.
WARNING! Under no circumstances use the motor lifting hole for balancing the weight (this lifting point is for the motor only when detached or detaching from the compressor).
Care MUST be taken to ensure that no small bore pipes or other components being trapped by slings.

CHAPTER 3 - INSTALLATION & COMMISSIONING 3.3.3 Lifting Instructions
Because the type of lifting equipment for each installation will be different the following instructions have been written with the intent of being a general guide rather than specific instructions. For compressor maintenance purposes a one tonne block is usually suitable to give good control of the lifting of components. 1.
2. 3. 4. 5.
Whatever your equipment or conditions, good safety procedures must be practiced, i.e.: a) Establish the actual weight of the load. b) Check whether the lift will be a straight lift, or will an angle rig be needed. These factors will affect the lifting capacity required. c) The slings must be free of kinks, knots, broken strands or loose connections etc, and meet the regulation requirements. d) Check the clearance available to make sure the lift can be attempted safely. e) To prevent damage to the machine's finish or the edges of the machine from cutting into the slings, use proper blocking and padding. Know your equipment, and anticipate potential hazards. When involved in the lifting of heavy loads, we suggest you protect yourself by wearing approved protective gear such as: safety helmets, steel toe cap safety shoes, gloves, eye protection, etc. Prepare the installation area before moving the machine. Refer to the machine installation drawings and note the location of the machine support points. Review all machine installation requirements carefully before positioning the machine.
3.3.4 Unpacking No special unpacking instructions can be given here as the compressors may be transported fully boxed, crated, or on open bases, depending on destination and mode of transportation. Boxed compressors have directions for lifting and opening on or with the boxes. Some of the cylinder valves will have been replaced with silica-gel bags. The displaced valves and the accessories are packed in a separate container, which should be located and safeguarded until after the installation of the compressor.

CHAPTER 3 - INSTALLATION & COMMISSIONING
3.4 Installation Procedure 3.4.1 Safety Precautions The following additional safety precautions should be observed before installing the compressor onto its foundation. Personnel must be a safe distance from the compressor during positioning, guide ropes may be used to assist, but not 'hands-on'. The compressor must be lowered slowly, in small stages with no sudden jerks whilst observing for any indications of potential problems. Once in position the compressor must be properly secured with suitable foundation bolts or anti-vibration mounts (AVM's). If the floor is to be drilled for foundation bolts, the compressor must be moved away whilst work proceeds. Each time the compressor is moved check for stability and correct sling placement. DO NOT apply load tension to the slings if the compressor is held to the floor. 3.4.2 Mounting Arrangements - Anti-Vibration Mounts A flat and level floor of sufficient strength to support the combined weight of the motor, compressor and ancillaries should be prepared in advance of the compressor delivery. The procedure should then be as follows: 1. 2. 3. 4. 5.
Ensure that the underfaces of the compressor feet are clean. Bolt the anti-vibration mountings on to the compressor feet. Move the compressor into position and mark on the floor the position of the holding down bolt holes in the anti-vibration mounting plate. Remove the compressor and attached mounts and drill the floor for appropriate size holes for the Raw-bolt shells. Insert shells, reposition compressor and bolt onto floor by means of the mounting holding down bolts.
OR: The anti-vibration mountings may be held down by bolts or anchors of a similar diameter to the holes in the mounting plate. Use of these will eliminate the need to move the compressor to drill the floor holes. The appropriate instructions supplied with the bolts should be followed precisely. 6.
Finally, check the bolts holding the compressor onto the anti-vibration mountings and use these bolts to finish levelling the compressor (See Levelling and Alignment).

CHAPTER 3 - INSTALLATION & COMMISSIONING 3.4.3 Levelling and Alignment - Flange Mounted Motors
Compressors with flange mounted motors are completely assembled and lined-up before shipping, it is therefore only necessary to set the machine on the foundations and level it in both directions as follows: 1.
Adjust the pressure within the pneumatic AVM's around the machine until the desired level is achieved. Do not inflate AVM's unless the static weight of the compressor is placed on them.
2.
Ensure that the final levelled height of each mount is within the makers limits and that each mount is levelled until it carries its correct proportion of the overall machine weight. If any mount is compressed solid, levelling must be carried out on the free mounts to redistribute the load. Using a spirit level on any horizontal surface, check that the compressor is level in both planes (i.e. parallel to and at right angles to the crankshaft). If NOT, then adjust again until satisfied.
3. 4. 5.
3.5 Preparation for Commissioning 3.5.1 Cleaning the Compressor The compressor must be thoroughly cleaned before preparing for commissioning. Care should be taken when making connections to see that no grit or impurities of any kind are allowed to enter while the compressor is being piped up and prepared for work. 3.5.2 Preparing the Compressor After works testing, the compressor is prepared for shipment. Before use therefore, the compressor will require to be prepared for use as follows: 1. 2. 3. 4. 5. 6.
Remove the 'mouldable' wrapping from around the piston rods and clean the rod surfaces. Remove control piping from cylinder valve covers marked with adhesive labels and remove the covers. Extract the silica gel bags from the valve chambers; ensuring that where more than one bag is present, ALL bags are removed. Using a plastic or soft metal scraper, remove rust resistant paint from the seating in the valve chambers. Remove the valve assemblies from their wrappings. Fit components in their correct order, ensuring that suction and delivery valves are fitted in the correct valve chambers. Where plate lifters are fitted to suction valves, care must be taken to ensure correct assembly.

Tighten the valve covers and refit the control air pipes Remove and store the adhesive labels and warning plates with the silica gel bags. Check that all gauges and small-bore pipework are undamaged, and are properly connected. Ensure that all external nuts and bolts on the compressor and its ancillary equipment are tight, including all holding down bolts and bolts of all pipework flanges and supports. Remove the crankcase access covers (and wooden blocks where fitted), and crosshead access aperture covers, and check to ensure that the interior of the crankcase is clean and free of foreign matter. Ensure free movement of compressor motion by turning the crankshaft round a number of times in the correct direction of rotation. Fill the oil sump (in the bottom of the crankcase) with the recommended grade of lubricant to level indicated by the window nut on the front of the crankcase. Initially fill to near the top of the window, the level will fall towards the bottom of the window when the compressor is started, rising to about half-way when the oil has reached its sustained running temperature. Wearing suitable (oil resistant) protective gloves, liberally coat clean oil onto all the main guide slides - turning the crank to different positions to achieve full face coverage (keep hands out of the crankcase when the shaft is being turned). As the compressor may have been in transit/storage for some time, prime the suction side of the lubricating oil pump by disconnecting the suction pipe top fitting. Then using the recommended grade of lubricant pump oil 'in' to 'wet' the gears and fill partially the suction side of the pump body. This promotes a quick pick up of oil pressure on start up of the compressor. Refit the crankcase and crosshead access covers. Ensure that the compressor pressure instrument isolating cocks are open. Ensure that the pipes of the rubber filling plugs are removed to vent the gauge cases and allow correct gauge indication. Ensure that the pressure signal pipelines of the load control system are open (i.e., make certain that any isolating valves are fixed open). Fill slowly and carefully (to avoid trapping air) in the cooling water spaces of the compressor - do not rush this operation. Open the air vent cocks, at the tops of the cylinder covers to rid the system of trapped air. The operation is carried out in association with any other water-cooled ancillary items in the overall cooling water system of the installation.

CHAPTER 3 - INSTALLATION & COMMISSIONING 3.5.3 Preparing the Motor
Check the driving motor insulation resistance (IR) using a 500 volt megohmeter taking note that the insulation resistance in mega-ohms, measured between any terminal and the frame with the machine cool, is infinity. If the windings have become damp and the insulation resistance is low, then the windings must be thoroughly dried out and re-tested for satisfactory condition before commissioning.
CAUTION! Before using the insulation tester disconnect the supply leads at the motor terminals so that only the motor windings are tested. This will avoid the possibility of the test instrument potential destroying any electronic equipment that may be in ancillary circuits. 3.5.4 Motor Rotation Check The compressor is designed to rotate in a clockwise direction when viewed from the drive end.
CAUTION! Running the compressor with incorrect rotation will result in serious damage. After checking it is safe to do so, switch on the electricity supply to the compressor control panel. Prepare the compressor for an 'unloaded' start and press the START button, as soon as the compressor starts press the STOP button. Check motor is rotating in the correct direction (indicated on motor end). In the event of wrong direction of rotation, isolate the machine immediately. A qualified electrician must rectify the problem before rechecking.
3.6 Commissioning the Compressor Before commissioning the compressor, read and fully understand Part 3 "Operation" and any associated literature regarding the control panel and any other ancillary equipment. 3.6.1 Trial Run When commissioning, the trial run must include certain vital checks, and these should be carried out as follows: 1. 2. 3. 4. 5.
Ensure that the factory delivery mains and air using equipment are safe to pressurise - and all delivery isolating valves in the system are open. Ensure that the load control sensing pipework is open to the compressed air main. Ensure that the isolating cocks of all pressure gauges are open. Ensure that the by-pass valves situated at the drain traps are closed. Start compressor in the unloaded condition and allow to run up to full speed, observe oil pressure is quickly established (this will be high with a cold machine) and observe compressor running generally.

CHAPTER 3 - INSTALLATION & COMMISSIONING 6.
After a 3 minute run, stop and electrically isolate the compressor. Remove the crankcase main doors and check the temperatures of the motion work bearings and guides. This should be done using a thermometer fitted with a suitable surface probe.
WARNING! Take care during examination, as some of the parts will have become heated. All should be cool except the bottom end bearings, which can be a little warmer than other bearings - also one side (the 'working face' side) of main guides may be slightly warmer than the opposite side. 7. 8. 9. 10.
Refit the crankcase main doors and reconnect the compressor. Run the compressor for a further 10 minutes and repeat checks as in step 6. When satisfied that all is in order, restart the compressor. When the compressor has settled on speed place the load control to the load condition whereupon the compressor will commence compressing. Observe compressor operation and the build up of pressure.
The load control must be set for no higher pressure than that for which the compressor is supplied. (See Section 1.1.1 Technical Data). During the first commissioning run on load, make careful observation of the general operation of the compressor. Observe the compressor gauges, until the desired unloading set-point (as set on the load control pressure switches) is reached, at this point the compressor will unload automatically as described in Load Control System. Check that the loading/unloading sequence is in accordance with requirements - adjust the control as necessary. 3.6.2 Completion of Commissioning 1.
2.
3.
Run the compressor until it attains operational temperature and check that the oil pressure settles at a satisfactory level, approx. 3.5 Bar or above; this will depend upon ambient temperature, oil viscosity at running temperature, and on-load/offload running pattern. After a settled period of running (approx. 24 hours) check the tightness of all external bolts and nuts - particularly cylinder and valve cover fasteners, also compressor and compressor driver fixings - to complete the commissioning of the machine. During this run (on water-cooled machines) adjust the cooling water flow control valve to achieve the required temperature rise. When on sustained full load, the optimum temperature rise is about 10o to 12o C.

OPERATING INSTRUCTIONS These instructions are designed to providing experienced operatives, who are fully conversant with compressor operating techniques, with operational information for the Gardner Denver Belliss & Morcom 'PET' range compressors. Note: The following operating information assumes that the compressor is fitted with a standard Gardner Denver Belliss & Morcom control system. However, if the control equipment is of different manufacture, the compressor MUST be operated in accordance with the supplementary Operating Information supplied with the control system. The compressor is designed and built for continuous running and will provide long term reliable operation if regular periodic checks and servicing are carried out in accordance with the information provided within Chapter 5 of this Instruction Manual.
CAUTION! Prolonged unloaded running of the machine should be avoided not only because of power wastage, but unnecessary component wear can result. It is the customer's responsibility to: 1) 2) 3)
Maintain the inlet filter system and air blast cooler in a clean condition as dictated by site conditions. Ensure that the specified, clean lubricant is added to ensure the correct crankcase oil level is maintained Report promptly to Gardner Denver Belliss & Morcom Service Department any operating abnormalities faults defects or malfunctions of the compressor and/or associated ancillary equipment. Such reports must be forwarded in writing by facsimile transmission. Oral reporting shall be deemed to be acceptable if confirmed in writing in the following 48 hours.
4.1 Controls and Indicators 4.1.1 Starter System If supplied with your compressor, the standard Gardner Denver Belliss & Morcom starter control equipment consists of a two compartment panel enclosed in a dust and damp proof wall or floor mounted sheet steel cubicle, and suitable for use on various electrical supplies. The panel incorporates the following features: 1) 2) 3) 4)

High outlet air temperature - aftercooler Low cooling water flow 'Test' pushbutton to check panel lamps. 'Reset' pushbutton to clear the alarm annunciators and make the compressor available for restarting. This ensures the compressor cannot be restarted except as a deliberate operator action (with selector in Unload or Manual only). Pressure switches and solenoid valves to give 3 step load control with automatic unloaded starting and stopping. A panel mounted mains isolator, interlocked with the start circuit. Ammeter for motor drive current. 'Hours Run' meter. Automatic stop/start to give shutdown after 15 to 30 (adjustable) minutes unloaded running and restart on pressure demand.
Faults are indicated on annunciators with a single fault resulting in simultaneous alarm and shutdown. The fault protection equipment is interlocked with the starter to give automatic override of the oil pressure/low cooling water flow fault conditions during start sequence. The fault circuit is enabled after a short delay in the start cycle. For additional features, see the Operating Philosophy Document provided (where necessary). If a plc panel is supplied - please refer to separate instructions. 4.1.2 Load Control System Functions All of the suction valves in the compressor have actuators, which cause the valve plate to be held off its seat whenever a pneumatic signal is applied. When the plate is held open then the compression can take place. If all suction valves are held open then the compressor is 'OFF LOAD'. On removal of the pneumatic signal the plate returns to its seat and compression can then recommence. The unloader is pushed back by the valve plate springs and the unloader return spring. If only the upper set of suction valves are held open then the compressor is on 'HALF LOAD'. Three-Step Load Control means that the compressor is either on:FULL LOAD (compression taking place) - all suction valves being in service or HALF LOAD (compression taking place in bottom half of cylinder only) - lower set of suction valves only in service. or OFF LOAD (no compression taking place) - all suction valves being held open.

CHAPTER 4 - OPERATING INSTRUCTIONS
A complete 'Full Load' to 'Half Load' to 'Off Load' and return to 'Half Load' and 'Full Load' sequence occurs as follows:The Compressor is on FULL LOAD Assuming the compressor is running on Full Load and pressure in the delivery main is rising (too much air is being supplied by the compressor for the reducing requirements of the end using equipment). When the pressure rises to the upper limit of pressure switch (PS2), PS2 will de-energise solenoid valve (SV2). This will then allow pneumatic signal to pass into the small-bore pipework interconnecting the upper set of suction valve actuators. This causes the upper set of suction valves to be held open and the compressor therefore runs on Half Load. The Compressor is now on HALF LOAD Assuming that pressure in the delivery main is still rising - when the pressure rises to the upper limit of pressure switch (PS1), PS1 will de-energise solenoid valve (SV1). This will then allow pneumatic signal to pass into the small-bore pipework interconnecting the lower set of suction valve actuator. This causes the lower set of suction valves to be held open and the vent valves to vent to atmosphere (blow down), thereby reducing the pressure within the compressor to atmospheric levels. The Compressor is now OFF LOAD Assuming the pressure in the main now begins to fall (as insufficient air is being supplied to meet the demand), and the low air limit of PS1 is reached, then PS1 will energise SV1. This will then isolate the pneumatic signal to the lower set of suction valve actuators and the vent valves. The lower set of suction valves will re-seat, the vent valves close and the compressor returns to HALF LOAD operation. The Compressor is back on HALF LOAD Assuming the pressure in the main is still falling - when the pressure falls to the lower limit of PS2, then PS2 will energise SV2. This will then isolate the pneumatic signal to the upper set of suction valve actuators. The upper set of suction valves will re-seat and the compressor returns to FULL LOAD operation. The Compressor is back on FULL LOAD If at any point of the sequence the demand increases or decreases randomly, then the pressure switches react to maintain the compressor load function at the required level to meat the change demands. The set points of the pressure switches are given in Chapter 1 - Technical Data.
4.2 Preparation for Starting Note: The following operating information assumes that the compressor is fitted with a standard Gardner Denver Belliss & Morcom control system. However, if the control equipment is of different manufacture, the compressor MUST be operated in accordance with the supplementary Operating Information supplied with the control system.

CHAPTER 4 - OPERATING INSTRUCTIONS 4.2.1 Before Operating the Machine (Pre-Start Checks) 1) 2) 3)
4) 5) 6) 7) 8) 9)
Establish that it is safe to discharge high-pressure air into the delivery lines. Ensure that all machine guards are correctly fitted to the machine and auxiliary equipment. It is IMPORTANT that any loose, missing or damaged guards are correctly fitted before attempting to operating the compressor. Check that access ways around the machine are clear and free from tripping or slipping hazards. Remove any obstacles and neutralise any fluid spillage such as oils or greases, using an absorbent material. Allow spillage to be absorbed for a short time before thoroughly cleaning the spillage area. Ensure that all of the fault warning, annunciators are extinguished and that the compressor is safe to start. Check oil level in sump. Correct level is halfway up window nut in front face of crankcase. If the machine has been standing idle for some time it may be necessary to prime the oil pump. Ensure that the cooling water supply valve is open promoting water circulation through the compressor jackets, intercoolers, aftercooler and oil cooler. Ensure that the air pressure sensing pipeline from the air main to the pressure switches and solenoid valves in the control panel is locked open. Ensure that the main air-isolating valve is OPEN.
4.3 Starting the Compressor 4.3.1 Under Normal Conditions Step 1) Turn the main isolator to the 'ON' position 2) Press the 'CONTROLS ON/RESET' illuminated pushbutton to reset the Safety Relay 3) Press the 'RESET' pushbutton to energise the fault monitoring relays FR1 to FR4. (press the 'RESET' push-button only with the selector in UNLOAD or MANUAL)
Supplementary Information The 'SUPPLY ON' lamp will illuminate. The hazard lamps will illuminate to indicate they are all operational. This removes the supply from the hazard lights whilst retaining their respective relays
Ensure that the 'TRIPPED' indicator is extinguished, if illuminated reset thermal overload (OL1) and/or thermistor relay (THR1). 4) Select 'MANUAL' on the 'UNLOAD/ MANUAL/AUTO' selector switch 5) Press the 'START' pushbutton.
The Hours Run Meter will be energised as soon as the 'START' pushbutton is pressed.
When the 'START' pushbutton is pressed, the motor starter will energise by pulling in the Star (SC) contactor and the Main (MC) contactor. After a small delay, set by the timing relay (MCT1), (usually between 15 and 20 seconds) the Star contactor will deenergise and the Delta (DC) contactor will energise. When the delta contactor is energised the 'RUNNING' indicator lamp will be illuminated indicating that the motor is now running at full speed and the compressor is ready for use.

CHAPTER 4 - OPERATING INSTRUCTIONS
The commissioning timer (CTD) will be energised when the start relay (SR1) is energised. The commissioning timer (CTD) should be set for approximately 15 seconds. After this time period has elapsed the time contacts change state and allow the fault circuit to check for low cooling water flow (LCWF) and low lubrication oil pressure (LLOP). If either of these items have failed to reach their working levels during the start-up period, the compressor motor will trip and a fault will be indicated. 4.3.2 After An Emergency Stop Rectify fault condition and proceed from Step 2 of 4.3.1 Starting Compressor Under Normal Conditions.
4.4 Running 4.4.1 Running Checks 1. 2. 3.
4. 5. 6.
Allow the compressor to run up to full speed and then close the small drain cocks. Check the oil pressure. This will fall initially as the oil temperature rises, but should steady at between 1.8 to 4.0 Bar G even in a hot environment. Check the cooling water is flowing at the visible outlet or flow indicator. On multicompressor installations balance the flows in the parallel systems of the compressors (including intercooler) to give equal water temperature rise across both - ideally 11ºC. Check all automatic drain traps for unusual discharge. Check all temperatures and pressures periodically. Check for undue noise, vibration or heat. If present, report immediately.
It is good practice to carry out these checks regularly and log the results. 4.4.2 Automatic Operation Before Automatic Operation is selected, the compressor must be prepared for starting as described in 4.2.1 Pre-Start Checks. Once the compressor is running, 'AUTO' may be selected using the 'UNLOAD/MANUAL/AUTO' selector switch. This will allow the compressor to automatically stop and start on the dictates of the Light Run Timer (LRT) which is usually set at between 15 and 30 minutes. If the compressor has not been on load during the preset period, the compressor will automatically shutdown. During the shutdown period an indicating lamp is illuminated to show that the compressor is on 'AUTO STANDBY'. When air is again required, the compressor will automatically start. 4.4.3 Faults/Hazards Should a fault develop, this will be detected by the appropriate sensing switch and this in turn will de-energise the appropriate fault relay (FR1 to FR4) and illuminate the appropriate fault indicator. This will automatically stop the motor via the motor starter. The compressor will be automatically unloaded via the CTD timer, which will be deenergised by the motor starter.

4.5 Stopping the Compressor 4.5.1 Normal Stopping Step 1) Select the 'UNLOAD' position on the 'UNLOAD/MANUAL/AUTO' selector switch. The 'NO LOAD' indicator lamp will illuminate. 2) Press the 'STOP' pushbutton.
Supplementary Information This ensures that the compressor is fully unloaded before stopping. This will allow moisture to be purged from the cylinders. The compressor will stop automatically in a controlled manner.
3) Close the main isolating shut-off valve. 4) Open vent valves. To fully de-pressurise system 5) Close the cooling water supply valve. To prevent unwanted circulation of water The compressor can also be stopped with the 'UNLOAD/MANUAL /AUTO' selector in the 'AUTO or MANUAL' position. However, this leaves the compressor in a pressurised state and is not recommended. DO NOT attempt to restart the compressor until it has automatically de-pressurised via the automatic blow-down valves. 4.5.2 Emergency Stopping Pressing the 'EMERGENCY STOP' mushroom button stops the machine instantly in whatever mode of operation it is operating.
CAUTION! This is not recommended for routine stopping and should only be used in the case of an emergency where normal stopping is not possible or is impractical.
4.6. Fault Indications The following is a list of indications of possible faults which could arise in service; periodic surveillance of pressures and temperatures, etc, will establish the normally experienced levels applicable to the site and load conditions. Variation from these due to a fault arising may be slow to impinge - the early effect of a fault (with the robust reciprocating type machine) being, usually very gradual. It is IMPORTANT therefore, to retain a simple daily record sheet of pressures and temperatures. Comparison with previous readings will then warn if there is an untoward trend arising - when reference to the following fault indication's list will indicate the probable cause and remedial action to take. A copy of a typical log sheet is provided in the Appendices located at the end of this manual. The running performance of the compressor can also indicate when it is necessary to renew a particular part: Generally, wear or malfunction of valves or piston rings will be indicated by variations (other than those due to suction or delivery conditions) in the interstage or final delivery pressure and temperature. Progressive crankcase bearing wear will slowly give rise to a gradual lowering of the lube oil pressure; if low oil pressure does occur and cannot be traced to any other cause listed, then connecting rod bottom end bearings should be inspected.

COMPRESSOR MAINTENANCE
WARNING! Before opening up the machine, all pressurised components MUST be depressurised down to atmospheric pressure in a safe and controlled manner.
5.1 Preventive Maintenance This schedule of maintenance, in general terms, is a preventive maintenance guide and running service necessary for our range of reciprocating compressors. However, it does not cover for any eventualities, which could occur from neglect or incorrect operation by the customer or adverse environmental conditions. Before carrying out any preventive maintenance work related to this equipment it is a requirement that you read and work in accordance with the Safety Precautions given in Chapter 2 of this Instruction Manual. Also, for your own protection, be sure to read and obey WARNING and CAUTION notices and observe any special notes you find in this Chapter and any associated literature. When working on the compressors rotational parts you MUST fit piston rod clamps to prevent possible uncontrolled movement of the crankshaft and motion work. Refer to Maintenance Procedure Job No. 002 Fitting Piston Rod Clamps. On plants with two or more compressors the opportunity should be taken during the early weeks of running, following commissioning, to vary the service hours of the compressors so that no two machines reach their maintenance interval at the same time. A gap of about 200 hours between machine running times is recommended. When 'running-in' a new compressor the crankcase oil MUST be renewed after the first 500 hours of operation and thereafter change in accordance with the intervals laid down in the following maintenance schedule. 5.1.1 Maintenance Schedule The following schedule, lists recommended maintenance tasks which are designed to both prevent unplanned machine breakdowns and to help the maintenance teams to plan maintenance activities. Where a maintenance activity requires greater explanation than that given in the schedule a reference to the relevant associated maintenance instruction is given. All materials used for scheduled maintenance and repair MUST COMPLY with Gardner Denver Belliss & Morcom standards and the standards laid down by associated equipment manufacturers. Only approved spares may be used. When a system component associated with a mechanical or electrical device is changed or renewed, the system must undergo a functional test before the equipment is returned to service. Gardner Denver Belliss & Morcom are not responsible for premature failures of parts which are caused by neglect, inappropriate servicing, use of none Gardner Denver Belliss & Morcom parts, or any other similar conditions over which we have no control.

To Remove There are two ways of removing the piston from the compressor: Method 1 is as a unit without the piston rod (this procedure) and Method 2 as an assembly with the piston rod attached. This method can be used if the maintenance procedure being performed does not call for the piston nut to be removed. If Method 2 is to be used the piston removal procedure is detailed as part of Job No.013 Piston Rod - Remove/Refit. The '1st stage piston' can only be removed using Method 2. 1) Remove the cylinder top cover as described in Job No.003. 2)
Remove the crosshead access cover and gasket from the crankcase.
3)

JOB No. 004 - PISTON RINGS - REMOVE & REFIT (Cont) Bend back the tab on the locking plate retaining the piston rod/crosshead securing pin and remove the pin. Ensure that the securing pin is removed before slackening the piston nut. Otherwise, if the piston rod turns in the crosshead while the securing pin is in position, the pin will distort making it extremely difficult to remove.
5)
Slacken the piston nut.
WARNING! It is possible that pressure can have accumulated within the interior of the piston. There is a pressure release hole drilled in the piston top half, which is (on assembly) covered by the underside of the piston nut/washer. It is essential, where the hole is covered by a washer, to ensure that the washer is not stuck in place before the nut is unscrewed by more than one turn. This is to make certain that the pressure relief hole is fully open to atmosphere. 6)
Remove the piston nut.
7)
Remove the piston and washer by lifting the piston (which is in halves) very carefully off the rod. If the piston is tight on the rod and cannot be easily lifted, proceed as follows:
8)
Manually 'bar-over' the compressor to turn the piston to TDC and insert diametrically opposite (IMPORTANT) two equal length pieces of hard wood via valve pockets to block the piston. Place the wood chocks about 25mm clear of the piston rod sides NOT at the piston periphery.
9)
Turn the crankshaft to BDC to withdraw the rod.
10)
Carefully turn the compressor back to TDC taking the piston upwards.
11)
Insert longer pieces of hard wood if the piston is still tight on the rod and repeat steps 9 and 10. An observer MUST be stationed to control the piston emerging from the cylinder. The two halves being lifted separately from the rod top with care being taken to remove the piston rings safely during the operation.
12)
Remove the wood blocks when the piston has been lifted out. If the piston halves are stuck together, lift the piston off as an assembly and part the halves carefully on a work-bench taking care not to damage the piston body.
Examination Piston Pressure Rings - For piston pressure ring dimensions refer to Chapter 1 Technical Data. The pressure rings MUST be replaced with new ones when the radial thickness at any point has worn to 65% or less of the original thickness. Piston Bearer Rings - For piston bearer ring dimensions refer to Chapter 1 Technical Data. The bearer rings MUST be replaced by new ones, when the standout at any point has worn to 0.5mm or less.

CHAPTER 5 - COMPRESSOR MAINTENANCE
JOB No.005 - PISTON/CYLINDER END CLEARANCES - INSPECTION (Cont) 2)
With the piston exactly at TDC or BDC, insert a feeler gauge through the valve pocket and measure the clearance. Record the end ("bumping") clearances with the piston at the top (Top-Dead-Centre) and bottom (Bottom-Dead-Centre) of its stroke. The clearances are detailed in Chapter 1 Technical Data. If the clearances are outside of the tolerance band the clearance MUST be adjusted (see later in this procedure).
CAUTION Feeler gauges MUST NOT be inserted into the valve pocket whilst turning the machine over because if trapped, the machine components could be strained or damaged. Piston/Cylinder End Clearances - Adjustment The end ("bumping") clearance is adjusted by screwing the piston rod into, or out of, the crosshead. To adjust the piston to cylinder end clearances proceed as follows: 1)
Remove the crosshead access cover and gasket from the crankcase.
2)
Bar over the crankshaft to reveal the crosshead locknut and the piston rod securing pin.
3)
Bend back the locking plate tab retaining the securing pin and remove the pin. Ensure that the securing pin is removed before slackening the crosshead nut. Otherwise, if the piston rod turns in the crosshead while the securing pin is in position, the pin will distort making it extremely difficult to remove
4)
Slacken the crosshead locknut. The piston rod has a slotted end at the crosshead (through which the securing pin fits) it can only be turned in 90o steps, one step represents a linear movement of 0.8mm, (the screwed end of the rod having 8 threads per inch).
5)
To adjust the top end clearance, screw the piston rod into or out of the crosshead. Ensure that the top and bottom clearances are as close to equal as is possible. If equal clearances are not obtainable then always, on final setting, make the TOP clearance the larger of the two (by an amount equal to no more than one quarter turn only of the piston rod in the crosshead i.e., by no more than 0.8mm).
6)
Fully tighten the crosshead locknut.
7)
Recheck that the piston rod slots are correctly aligned for clearance of the piston rod securing pin.
8)
Fit a new locking plate to the securing pin before fitting and fully tighten the pin.
9)
Bend over the locking plate tab to prevent the securing pin from rotating.
10)
Inspect the crosshead access cover gasket. Renew if necessary.
11)
Refit the access cover.

JOB No. 013 PISTON RODS - REMOVE & REFIT LIST OF CONSUMABLES Description Industrial cleaning fluid (White Spirit) & lint free cloth
Qty As required
To Remove 1) Remove the cylinder top cover as described in Job No.003. 2)
Remove the piston as described in Method 1, Job No.004 or if the piston rod is to be removed with the piston attached skip this step. Before slackening the crosshead locknut mark on the crosshead two fine centre-punch dots (about 70 to 75mm apart). One on the piston rods taper portion and the other on the crosshead. Then, set a pair of dividers to the length between the dots and record this figure.
3)
Remove the securing pin from the crosshead.
4)
Unscrew the piston rod from the crosshead - the loosened locknut should be held by a spanner to be unscrewed off the rod end simultaneously, and removed as the rod is withdrawn.
5)
Using suitable lifting equipment, carefully withdraw the piston and rod assembly from the cylinder
If the packing gland is to be reused, great care must be taken as the threaded portion of the rod is lifted through the gland rings to prevent damage. To Refit Prior to refitting the piston rod, examine the rod with a gauge and if found to be worn (evenly or tapered) or scored then renew as necessary. 1)
Fit the piston rod, using a piston rod thread guard cap, to pass through the packing gland and scraper gland until it just enters the guide top.
2)
Remove the cap and fit the crosshead locknut at the crosshead as the rod enters the guide. When refitting the rod, ensure that the centre-punch dots coincide at the correct distance apart and check the alignment of the cruciform slot at the bottom of the rod to the securing pin hole in the crosshead, before tightening the locknut on the crosshead.
3)
Ensure that the securing pin can pass through the piston rod foot (slot in line) and tighten the locknut to the crosshead.
4)
Refit the piston as described in Job No.004 (if necessary).
5)
Check the piston bumping clearances as described in Job No.005.
6)
Turn the compressor over a couple of times to ensure satisfactory operation.

CHAPTER 5 - COMPRESSOR MAINTENANCE
JOB No. 014 OIL FILTER - REMOVE & REFIT LIST OF CONSUMABLES Description Industrial cleaning fluid (White Spirit) & lint free cloth
Qty As required
To Remove 1) To open the filter body undo the bottom bolt (using a clean bucket to catch spilled oil), the filter body and element draw off vertically downwards. 2)
Discard the old element and clean out the body.
3)
When replacing the assembly (with a new filter pack) care should be taken that the seal ring gasket at the top and the washer at the bottom are in their correct positions. A new seal ring gasket is supplied as part of the filter element spare.
4)
There is a spring fitted internally onto the bolt - this is installed to hold the filter element up against the top cover and so form the seal; it also provides the automatic safety filter bypass (for use should the element become heavily fouled).
5)
Before assembly of the filter body to its cover, fill the body with clean compressor lubricating oil.
JOB No. 015 OIL PRESSURE RELIEF VALVE - ADJUSTMENT LIST OF CONSUMABLES Description Industrial cleaning fluid (White Spirit) & lint free cloth
Qty As required
To Adjust 1) Remove the valve cap. 2)
Slacken the locknut on the adjusting screw and adjust to obtain the required oil pressure (screw IN to raise the pressure, screw OUT to decrease the pressure).
3)
Tighten the locknut and refit the cap.
4)
Normally adjustment is not necessary after initial setting by the manufacturer. If a fault should occur and adjustment has no noticeable effect, the trouble could be a particle of foreign matter trapped under the valve. Dismantling, cleaning and re-assembly is then required (first noting the valve adjusting screw setting).

JOB No. 016 LUBRICATING OIL PUMP AND DRIVE - INSPECT & OVERHAUL LIST OF CONSUMABLES Description Industrial cleaning fluid (White Spirit) & lint free cloth
Qty As required
To Overhaul 1) Disconnect all pipes connected to the oil pump. 2)
Remove the cap screws securing the oil pump to bearing housing and carefully withdraw the pump, together with the filter body attached, its drive coupling can then be inspected.
3)
Wear on the coupling is expected to be negligible but if excessive wear is present investigate the cause, remove, and fit a new drive coupling.
4)
When refitting the oil pump renew the gasket if the old one has deteriorated.
5)
Prime the suction side of the pump with oil.
6)
Refit the pipework to the oil pump.
JOB No. 017 INTERCOOLER - INSPECT & OVERHAUL LIST OF CONSUMABLES Description Industrial cleaning fluid (White Spirit) & lint free cloth
Qty As required
To Inspect 1) The cooler MUST be removed completely in order for a complete examination to be performed. Internal and external inspection, to check for fouling or damage, is annual. This period will, however, vary depending on site conditions (being extended with good clean water circulating). To Overhaul 1) It is not expected that the inside (i.e., tube internals) will foul. Any untoward accumulation of soft deposits at the tube entrance may be removed by blowing backwards with compressed air, the cooler being off the compressor for this purpose. 2)
If hard carbonaceous deposits have accumulated, specialist attention may be required.
3)
Should the cooling water side become fouled then use a proprietary procedure as recommended by local water treatment specialists - this to be compatible with the materials of construction (see Chapter 1 - Technical Data).
4)
When refitting (after cleaning) all joints must be in good condition.
