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 illustra-
tion 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 con-
nection later.
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).
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.
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.
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.
To remove the holder,
press the bottom of
chassis near the holder
upward and pull the tab
out of its hole.
