Piping
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.
For left rear piping
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.
