.5.2 Connection of piping--Indoor

1) Preparing the indoor unit's piping and drain hose for

installation through the wall.

2) Remove the plastic tubing retainer(see illustration

below) and pull the tubing and drain hose away from

chassis.

3) Replace the plastic tubing holder in the original posi -

tion.

A. Route the indoor

tubing and the

drain hose in the

direction of rear

right.

B. Insert the connecting cable into the indoor unit from

the outdoor unit through the piping hole.

1) Do not connect the cable to the indoor unit.

2) Make a small loop with the cable for easy connection

later.

3) Connecting cable

D. Indoor unit installation

• Hook the indoor unit onto the upper portion of the

installation plate.(Engage the two hooks of the rear

top of the indoor unit with the upper edge of the

installation plate.) Ensure that the hooks are properly

seated on the installation plate by moving it left and

right.

Press the lower left and right sides of the unit against the

installation plate until the hooks engage into their slots(click -

ing sound).

C. Tape the tubing, drain hose and the connecting

cable. Be sure that the drain hose is located at the

lowest side of the bundle. Locating at the upper

side can cause drain pan to overflow inside the

unit.

E. Connecting the pipings to the indoor unit and

drain hose to drain pipe.

• Align the center of the pipings and sufficiently tighten

the flare nut by hand.

NOTE:

If the drain hose is routed inside the room, insulate the

hose with an insulation material

*

so that dripping from "sweat-

ing"(condensation) will not damage furniture or floors.

*

Foamed polyethylene or equivalent is recommended.
