Service Manual 21
Indoor
1. Prepare the indoor unit's piping and drain hose for installation through the wall.
2. Remove the plastic tubing retainer(see the illus-
tration by) and pull the tubing and drain hose
away from chassis.
3. Replace only the plastic tubing holder 1, not the
holder 2 in the original position.
Route the indoor tubing and the drain
hose in the direction of rear left.
Insert the connecting cable into the indoor unit
from the outdoor unit through the piping hole.
• Do not connect the cable to the indoor unit.
• Make a small loop with the cable for easy con-
nection later.
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.
If the drain hose is routed inside the room, insu-
late the hose with an insulation material* so that
dripping from "sweating"(condensation) will not
damage furniture or floors.
*Foamed polyethylene or equivalent is recom-
mended.
Indoor unit installation
• Hook the indoor unit onto the upper portion of
the installation plate.(Engage the three hooks of
the rear top and rear lower of the indoor unit with
the upper edge and lower edge of the installation
plate.) Ensure that the hooks are properly seated
on the installation plate by moving it left and
right.
