3-24. Installing the Drain Hose

a) The drain hose should be slanted downward to the

outside. (Fig. 3-79)

b) Never form a trap in the course of the hose.

c) If the drain hose will run in the room, insulate the

hose* so that chilled condensation will not damage

furniture or floors.

* Foamed polyethylene or its equivalent is recom-

mended.

WARNING

Do not supply power to the

unit or operate it until all

tubing and wiring to the

outdoor unit are completed.

Left or left-rear tubing

(1) Pass the tubing and drain hose into the rear of the

indoor unit. Provide sufficient length for the con-

nections to be made.

Next, bend the tubing with a pipe bender, and con-

nect them.

(2) After performing a leak test, wrap the refrigerant

tubing and drain hose together with insulating

tape, as shown in the figure at right.

Then fit the tubing into the tubing storage space in

the rear of the indoor unit and clamp in place.

(3) Adjust the indoor unit so that it is securely installed

onto the rear panel.
