10. Installation
Preparing work for installation
■ Preparing the indoor unit's piping and drain hose for
installation through the wall.
■ Remove the plastic tubing retainer(see illustration
below) and pull the tubing and drain hose away from
chassis.
■ Replace the plastic tubing holder in the original position.
To remove the holder,
press the bottom of
chassis near the holder
upward and pull the tab
out of its hole.
CAUTION
While installing, make sure that the
remaining parts must be removed
clearly so as not to damage the piping
and drain hose, especially power cord
and connecting cable.
For left rear piping
1. Route the indoor tubing and the drain hose in
the direction of rear left.

flow 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.

■ 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(clicking sound).
5. Connecting the pipings to the indoor unit and
