Installation
1. Split Type Indoor Unit
• 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 connec-
tion 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 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.
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.
For left rear piping
To remove the holder,
press the bottom of
chassis near the holder
upward and pull the tab
out of its hole.
