There are two refrigerant pipes of different diameters:

◆ A smaller one for the liquid refrigerant

◆ A larger one for the gas refrigerant

A short length of piping is already fitted to the air conditioner. You

must extend this piping using assembly piping (optionally supplied).

The connection procedure for the refrigerant piping varies according

to the exit position of the piping from the indoor unit, as seen when

facing the air conditioner in position on the wall:

◆ Right (A)

◆ Left (B)

◆ Rear

1 With a knife, cut out the appropriate knock-out piece on the rear of the

indoor unit (unless you are connecting directly from the rear).

2 Smooth the cut edges.

3 Remove the protection caps on the pipes and connect the assembly piping

to each pipe, tightening the nuts, first manually and then with a wrench,

applying the following torque.

Pipe Outer Diameter Torque (kg•cm)

Liquid refrigerant 6.35 mm 160

Gas refrigerant 9.52 mm 300

Gas refrigerant 12.70 mm 500

➢

If the piping must be shortened or extended, 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 100 mm or more

6 Pass the piping through the hole in the wall.

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

circuit, refer to page 16.

➢ The piping will be insulated and fixed permanently into

position once the whole installation has been tested for

gas leaks; refer to page 17 for further details.
