6-17. Shaping the Tubing
(1) Shape the refrigerant tubing so that it can easily go
into the hole. (Fig. 1-45)
(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. 1-46))
(5) Assemble the refrigerant tubing, drain hose and
inter-unit wiring as shown in Fig. 1-47.
6-18. Installing the Drain Hose
(1) The drain hose should be slanted downward on the
outdoor side. (Fig. 1-48)
(2) Never form a trap in the course of the hose.
(3) If the drain hose will run in the room, insulate* the
hose so that chilled condensation will not damage
furniture or floors. (Fig. 1-49)
* Foamed polyethylene or its equivalent is
recommended.
