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.

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 43.

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.
