Left-side tubing

(1)Lead the tubing and drain hose through the wall, allowing sufficient length for connection. Then bend the tubing using a tube bender to make the attach- ment. (Fig. 38)

(2)Switch the drain hose and drain cap.

Switching drain hose and drain cap

(a)Locate the drain hose and the drain cap. (Fig. 39)

(b)Remove the screw fastening the drain hose on the right side, and pull out the drain hose to remove it. (Fig. 39)

(c)Apply moderate force to pull off the drain cap on the left side. (If you cannot pull it off by hand, use a long-nose pliers.)

(d)Reattach the drain hose to the left side and the drain cap to the right side. (Fig. 40a)

Drain hose

Slide the drain hose fully onto the drain pan outlet until the drain hose edge is pushed into the insula- tion. Check that the screw holes in the drain bracket and the drain pan outlet are aligned and securely in contact, then fasten them with the screw. (After attaching the drain hose, check that it is attached securely.) (Fig. 40c)

Drain cap

Use a Phillips screwdriver to push the drain cap in firmly. (If it is difficult to push in, wet the cap with water first.)

(3)Install the indoor unit on the rear panel.

(4)Connect the tubing and wiring led inside from out- doors.

(5)After completing a leak test, bundle the tubing together with armoring tape and store it inside the tubing storage area at the back of the indoor unit and hold it with clamps. (Figs. 40a and 41)
