2) Indoor Unit Installation

The mounting wall should be strong and solid enough to protect it from the vibration.

1. Mount the installation plate on the wall with four Type "A" screws.

(if mounting the unit on the concrete wall, consider using anchor bolts.)

• Always mount the Installation plate

horizontally by aligning the marking-off line by means of the thread and a level.

2. Drill the piping hole with 70mm dia. holecore drill.

• For right rear piping and left rear piping,

draw a line in the direction of the arrow marked "D". The meeting point of the two lines is the center of the hole.

• Drill the piping hole with a ø70mm hole

core drill. Drill the piping hole at either the right or the left with the hole slightly slanted to the outdoor side.

3. Piping and Drainage of Indoor Unit

1) Preperation of Pipings

1. Cut the pipes and the cable.

• Use the accessory piping kit or the pipes purchased locally.

• Measure the distance between the indoor and the outdoor unit.

• Cut the pipes a little longer than measured distance.

• Cut the cable 1.5m longer than the length of the pipe.

2. Remove burrs.

• Remove burrs from cut edges of pipes.

• Turn the pipe end toward down to avoid the

metal powder entering the pipe.

Caution:

If burrs are not removed, they may cause a gas leakage.

3. Flaring the pipes.

• Insert the flare nuts, mounted on the connection ports of both indoor and outdoor unit, onto the copper pipes. Some gas may leak, when the flare nuts are removed from the indoor unit, as some gas is charged to prevent the inside of the pipe from rusting.

• Fit the copper pipe end into the Bar of flare tool about 0.5~1.0mm higher. (See illustration)

• Flare the pipe ends.

4. Tape the flaring portion to protect it from the dust or damages.

When properly flared, the internal surface of the flare will evenly shine and be of even thickness. After the flare part comes into contact with the connectors, carefully check the flare finish.

2) Connection of Pipings

1. Remove the indoor tubing with Drain hose from the hole

• Remove tubing holder and pull the tubing out

of the chassis.

2. Replace the tubing holder into original position.

For right rear piping

3. Route the tubing and the drain hose straight backwards.

4. Insert the connecting cable into the indoor unit through the piping hole.

• Do not connect the cable to the indoor unit.

• Make a small loop with the cable for easy

connection later.

• Connecting cable

5. Tape the tubing, drain hose and the connecting cable. Be sure that drain hose locates at the lowest side of the bundle. Locating at the upper side can be a reason that drain water overflows drain pan inside the unit.

CAUTION

After the confirmation of the above conditions, prepare the wiring as follows:

1) Never fail to have an individual power specialized for the air conditioner. 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) See to 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.

• Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to the normal function of a overload protection device.

• Proper starting power is not given to the compressor.

7. Set the both liquid and gas side valves to open position with the Hexagonal wrench for the unit operation.

6. Air Purging

1) Air purging

The air which contains moisture remaining in the refrigeration cycle may cause a malfunction on the compressor.

1. Remove the caps from the 2-way and 3-way valves.

2. Remove the service-port cap from the 3-way valve.

3. Turn the valve stem of liquid side valve counter-clockwise approx. 90 and hold it there for ten seconds, then close it.

4. Check a gas-leakage of the connecting portion of the pipings.

CAUTION: Do not leak the gas in the air

during air purging. Use vacuum pump as far as possible.

Page 18

2) Checking a gas leakage

1. Connect the manifold gauge to the service port of 3-way valve. Measure the pressure.

2. Keep it for 5-10 minutes. Ensure if the pressure indicated on the gauge is as same as that of measured at first time.

NOTE:

The additional gas for air purping has been charged in the outdoor unit. However, if the flare connections have not been done correctly and there gas leaks, a gas cylinder

and the charge set will be needed.

CAUTION : Do not leak the gas in the air during air purging. Use vacuum pump as far as

possible.
