3-34. Shaping the Tubing

Right-rear tubing

(1)Shape the refrigerant tubing so that it can easily go into the hole. (Fig. 3-126)

(2)After performing a leak test, wrap both the refrigerant tubing and drain hose together with insulating tape.

The drain hose should be positioned below the refrigerant tubes, and should be given sufficient space so that no strong tension is applied to it.
