Installing and Connecting the Assembly Pipe of the Indoor Unit

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 must 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

1 Cut out the appropriate knock-out piece on the rear of the indoor unit unless you con-

nect 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.

Outer Diameter Torque

inch(6.35 mm) 10.1~12.3ft•lb(140~170kgf•cm)

inch(12.70 mm) 27.5~30.4ft•lb(380~420kgf•cm)

inch(15.88 mm) 31.8~34.7ft•lb(440~480kgf•cm)

➢

If you want to shorten or extend pipes, refer to page 11.

4 Cut off any excess foam insulation.

5 If necessary, bend the pipe round, along the bottom of the indoor unit and out through

the appropriate hole, taking care to ensure that:

◆ The piping does not jut out from the rear of the indoor unit

◆ The bending radius is 4inch(100mm) or more

7 For further details on how to connect to the outdoor unit and purge the air,

refer to page 12.

➢ The pipe will be insulated and fixed permanently into position after

finishing the installation and the gas leak test; refer to page 13 for

further details.

6 Pass the piping through the hole in the wall.
