• Be sure to run the power supply cable and the communication cable through electrical conduit as seen in the picture.

• Install the communication cable, indoor power cable and the main power cable in the cable tube.

• Secure the cable tube to the outdoor knockout using the CD connector and bushing.

• Arrange the cables as shown in the picture.

• The diameter of the 6 knock-out holes is Ø27.8 mm(Ø1-3/32 inch).

Installing and connecting the assembly pipe of the indoor unit

1. Cut out the appropriate knock-out piece (A, B, C) on the rear of the indoor

unit unless you connect the pipe directly from the rear.

2. Smooth the cut edges.

3. Remove the protection caps of the pipes and connect the assembly pipe

to each pipe. Tighten the nuts first with your hands, and then with a

torque wrench, applying the following torque:

4. Cut off the remaining foam insulation.

5. If necessary, bend the pipe to fit along the bottom of the indoor unit.

Then pull it out through the appropriate hole.



The pipe should not project from the rear of the indoor unit.



The bending radius should be 100 mm or more.

6. Pass the pipe through the hole in the wall.

7. For further details on how to connect to the outdoor unit and purge the air, refer to page 39~41.

Connect indoor and outdoor units with field-supplied copper pipes by means of flare connections. Use insulated seamless

refrigeration grade pipe only, (Cu DHP type according to ISO1337), degreased and deoxidized, suitable for operating pressures

of at least 4200 kPa and for burst pressure of at least 20700 kPa. Under no circumstances must sanitary type copper pipe be

used.
There are 2 refrigerant pipes of different diameters:

• The smaller one is for the liquid refrigerant

• The larger one is for the gas refrigerant

A short pipe is already fitted to the air conditioner. You may

need to extend the pipe using the assembly pipe (optional).
The connection procedure for the refrigerant pipe varies

according to the exit position of the pipe when facing the wall:

• Right(A)

• Left(B)

• Underside(C)

• Rear

• If you want to shorten or extend the pipes, refer to page 36~37.

• Tighten the flare nut with torque wrench according to specified method.

If the flare nut is over-tightened, the flare may break and cause refrigerant gas leakage.

• DO NOT WALL UP THE PIPE CONNECTION !

All refrigerant pipe connection must be easy accessible and serviceable.

• The pipe will be insulated and fixed permanently into position after finishing the installation and the gas leak test;

refer to page 43 for further details.
