•When installed in an insufficient strong place, the unit could fall causing injured.
Perform electrical work according to the installation manual and be sure to use an exclusive circuit.
•If the capacity of the power circuit is insufficient or there is incomplete electrical work, it could result in a fire or an electric shock.
Use the specified wires to connect the indoor and outdoor units securely and attach the wires firmly to the terminal board connecting sections so the stress of the wires is not applied to the sections.
• Incomplete connecting and fixing could cause fire.
Check that the refrigerant gas due not leak after installation is completed.
Attach the electrical part cover to the indoor unit and the service panel to the outdoor unit securely.
•If the electrical part cover if the indoor unit and/or the service panel if the outdoor unit are not attached securely, it could result in a fire or electric shock due to dust, water, etc.
Be sure to use the part provided or specified parts for the installation work.
•The use of defective parts could cause an injury or leakage of water due to a fire, electric shock, the unit falling, etc.
CAUTION
Perform grounding
•Do not connect the ground wire to a gas pipe, water pipe arrester or telephone ground wire. Defective grounding could cause an electric shock.
Do not install the unit in a place where an inflammable gas leaks.
•If gas leaks and accumulates in the area surrounding the unit, it could cause an explosion.
Perform the drainage/piping work securely according to the installation manual.
•If there is a defect in the drainage/piping work, water could drop from the unit and household goods could be wet and damaged.

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.

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.
