2) Connection of piping Indoor
• 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 posi-
tion.
1. Route the indoor tubing and the drain hose in the
direction of rear right.
2. 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
connection later.
3. 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.
4. 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 instal-
lation plate.) Ensure that the hooks are properly seat-
ed 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).
4. Connecting the pipings to the indoor unit and drain
hose to drain pipe.
• Align the center of the pipes and sufficiently tighten
the flare nut by hand.
For right rear piping
CAUTION
When install, 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.
