3-17. Shaping the Tubing (1) Shape the refrigerant tubing so that it can easily go into the hole. (Fig. 3-34) (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. 3-35)) (5) Assemble the refrigerant tubing, drain hose and inter-unit wiring as shown in Fig. 3-36. 3-18. Installing the Drain Hose (1) The drain hose should be slanted downward on the outdoor side. (Fig. 3-37) (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. 3-38) * Foamed polyethylene or its equivalent is recommended. WARNING Do not supply power to the unit or operate it until all tubing and wiring to the outdoor unit are completed.
