3-17. Shaping the Tubing
(1) Shape the refrigerant tubing so that it can easily
go into the hole. (Fig. 3-47)
(2) Push the wiring, refrigerant tubing and drain hose
through the hole in the wall. Adjust the indoor unit
so it is securely seated on the wall fixture.
(3) Carefully bend the tubing (if necessary) to run
along the wall in the direction of the outdoor unit
and then insulate to the end of the fittings. The
drain hose should come straight down the wall to
a point where water runoff will not stain the wall.
(4) Connect the refrigerant tubing to the outdoor unit.
(After performing a leak test on the connection,
insulate it with insulating tape. (Fig. 3-48)) Also,
refer to Section 10-5. “Connecting Tubing be-
tween Indoor and Outdoor Units”.
(5) Assemble the refrigerant tubing, drain hose and
inter-unit wiring as shown in Fig. 3-49.
