For right rear piping
Route the indoor tubing and the drain hose in the direction of
rear right.
Insert the connecting cable into the indoor unit from the out-
door unit through the piping hole.
• Do not connect the cable to the indoor unit.
• Make a small loop with the cable for easy connection 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.
NOTE: If the drain hose is routed inside the room, insulate
the hose with an insulation material* so that dripping from
"sweating"(condensation) will not damage furniture or floors.
*Foamed polyethylene or equivalent is recommended.
Indoor unit installation
• Hook the indoor unit onto the upper portion of the installa-
tion 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 installa-
tion 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).
