• Excessive torque can be cause of gas leakage. In case brazing the pipe, the nitrogen gas must be blown into the

pipe (50 Pa). The joint must be accessible and serviceable.

7. For further details on how to connect to the outdoor unit and purge the air, refer to page 38~40.

• 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.

Installing and connecting the drain hose of the indoor unit

When installing the drain hose for the indoor unit, check if condensation draining is adequate. When passing the drain hose through the 65-mm hole drilled in the wall, check the followings:

Wall

Indoor unit

Drain hose

The drain hose must not be bent.

The drain hose must NOT slant upwards.

5cm less

Keep a clearance of at least 5cm between the end of the drain hose and the ground.

The end of the drain hose must NOT be placed under water.
