3.Piping length and the elevation

• There should not be any heat source or

steam near the unit.

• There should not be any obstacles to prevent the air circulation.

• A place where air circulation in the room will be good.

• A place where drainage can be easily obtained.

• A place where noise prevention is taken into consideration.

• Do not install the unit near the door way.

• Ensure the spaces indicated by arrows from the wall, ceiling, fence, or other obstacles.

• If an awning is built over the unit to prevent direct sunlight or rain exposure, be careful that heat radiation from the condenser is not restricted.

• There should not be any animals or plants which could be affected by hot air discharged.

• Ensure the spaces indicated by arrows from the wall, ceiling, fence, or other obstacles.

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.
