Installing and connecting the assembly pipe of the indoor unit

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:

A

B

• Right(A)

 

 

• Left(B)

 

C

• Underside(C)

 

 

 

• Rear

 

 

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:

• If you want to shorten or extend the pipes, refer to page 35~36.

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 38~40.

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

refer to page 41~42 for further details.

• 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.
