1Cut 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.

2Smooth the cut edges.

3Remove 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:

NOTE

If you want to shorten or extend the pipes, see Step 2.9 Shortening or extending the refrigerant pipes (assembly pipe) on page 43.

4Cut off the remaining foam insulation.

5If 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.

6Pass the pipe through the hole in the wall.

NOTE

The pipe will be insulated and fixed permanently into position after finishing the installation and the gas leak test. For further details. see Step 4.1 Performing the gas leak tests on page 49.

CAUTION

Tighten the flare nut with a torque wrench according to specified method. If the flare nut is over-tightened, the flare may break and cause refrigerant gas leakage.

Do not box in or cover the pipe connection. All refrigerant pipe connection must be easily accessible and serviceable.
