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.
1. Route the indoor tubing and the drain hose in
the direction of rear left.
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 connect-
ing cable. Be sure that the drain hose is locat-
ed at the lowest side of the bundle. Locating
at the upper side can cause drain pan to over-
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.
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
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
drain hose to drain pipe.
■
Align the center of the pipings and sufficiently tighten
the flare nut by hand.
For left rear piping
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.
To remove the holder,
press the bottom of
chassis near the holder
upward and pull the tab
out of its hole.
