NOTE: • Thoroughly study the following installation locations: 1. In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the turbo fan, the fin of the heat exchanger and the drain pump, resulting in heat exchange reduction, spraying, dispersing of water drops, drain pump malfunction, etc. In these cases, take the following actions: • Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient capacity so that it draws oily steam which should not flow into the suction of the air conditioner.

• Make enough distance from a cooking room to install the air conditioner in such a place where it may not suck in oily steam. Air conditioner

ELECTRICAL WIRING 1. All wiring must comply with LOCAL REGULAT REGULATIONS. IONS. 2. Select a power source that is capable of supplying the current required by the air conditioner. 3. Feed the power source to the unit via a distribution switch board designed for this purpose. 4. The terminal screws inside the control box may be loose due to vibration during transport. Check the screws for loose connection. (Running the air conditioner with loose connection can overload and damage electrical components.) 5. Always ground the air conditioner with a grounding wire and connector co nnector to meet the th e LOCAL REGULA REGULATION. TION.

Piping Connection 1. Form the piping according to its routing. Avoid bending and bending back the same piping point more than three times. (This will result in hardening the pipe.) 2. After deforming the piping, align centers of the union fitting of the indoor unit and the piping, and tighten them firmly with wrenches. 3. Connect pipe to the service valve or ball valve which is located below the outdoor unit. 4. After completing the piping connection, be sure to check if there is gas leakage in indoor and outdoor connection.

Unit Drain Piping

Pipe clamp Indoor unit

• Drain piping must have down-slope (1/50 to 1/100): be sure not to provide up-and-down slope to prevent reversal flow. • During drain piping connection, be careful not to exert extra force on the drain port on the indoor unit. • The outside diameter of the drain connection on the indoor unit is 32mm.

Upward routing not allowed

Maintenance drain port

1/50~1/100

Piping material: Polyvinyl chloride pipe VP-25 and pipe fittings

MAX 700mm

• Be sure to execute heat insulation on the drain piping.

Heat insulation material: Polyethylene foam with thickness more than 8 mm.

Drain test

Feed water

The air conditioner uses a drain pump to drain water. Use the following procedure to test the drain pump operation:

Flexible drain hose (accessory) Main drain pipe

Drain Pump

Drain port

Glue the joint

Drain hose connection Use the clip (accessory)

Drain pan

Refrigerant piping time in high humid atmosphere (dew point temperature: more than 23°C), water drops Indoor unit are liable to fall. In this case, add heat insulation material according to the following Thermal insulator (accessory) procedure: • Heat insulation material to be prepared... Adiabatic glass wool with thickness 10 to 20mm. • Stick glass wool on all air conditioners that are located in ceiling atmosphere. • In addition to the normal heat insulation (thickness: more than 8mm) for refrigerant piping (gas piping: thick piping) and drain piping, add further 10mm to 30mm thickness material.

FORM THE PIPINGS 1. Wrap the connecting portion of indoor unit with the Insulation material and secure it with two Plastic Bands. (for the right pipings) •   If you want to connect an additional drain hose, the end of the drain-outlet should keep distance from the ground. (Do not dip it into water, and fix it on the th e wall to avoid swinging in the wind.)

Seal a small opening around the pipings with gum type sealer.

3. Test running 1) •PRECAUTIONS IN TEST RUN   The initial power supply must provide at least 90% of the rated voltage. Otherwise, the air conditioner should not be operated. For test run, carry out the cooling operation firstly even during heating season. If heating operation is carried out firstly, it leads to the trouble of compressor. Then attention must be paid. Caution Carry out the test run more than 5 minutes without fail. (Test run will be cancelled 18 minutes later automatically) • The test run is started by pressing the room temperature checking button and down timer button for 3 seconds at the same time. • To  To cancel the test run, press any button.

CHECK CHE CK THE FOL FOLLO LOWIN WING G ITE ITEMS MS WHE WHEN N INST INSTALLA ALLATIO TION N IS COM COMPLE PLETE TE • After completing work, be sure to measure and record trial run properties, and store measured data, etc. • Measuring items are room temperature, outside temperature, suction temperature, blow out temperature, wind velocity,, wind volume, voltage, current, presence of abnormal vibration and noise, operating pressure, piping velocity temperature, compressive pressure. • As to the structure and appearance, check following items. Is the remote controller switch operated? Is there any faulty wiring? Are not terminal screws loosened?

Is the circulation of air adequate? Is the draining smooth? Is the heat insulation complete (refrigerant and drain piping)? Is there any leakage of refrigerant?

As for the method of wiring, be guided by the circuit diagram pasted on the inside of control box cover. 2) Provide a circuit breaker switch between power source and the unit. 3) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation. Check them and make sure that they are all tightly fastened. (If they are loose, it could give rise to burn-out of the wires.) 4) Specification of power source 5) Confirm that electrical capacity is sufficient. 6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate. 7) Confirm that the cable thickness is as specified in the power sources specification. (Particularly note the relation between cable length and thickness.) 8) Never fail to equip a leakage breaker where it is wet or moist. 9) The following troubles would be caused by voltage drop-down.

4. Optional Operation 1) Two Thermistor System (1) Open the rear cover of the wired remote-controller to set the mode. (2) Select one of three selectable modes as follows. • Position 1: The room temperature is controlled by the thermistor of the main body. • Position 2: The room themperature is controlled by the thermistor of the wired remote-controller, control the temperature according to the position of wired remote-controller. • Position 3: The room temperature is controlled by lower temperature between the temperature of main body and of remotecontroller sensor.
