INDOOR UNIT
CUTTING THE HOLE IN THE WALL FOR THE CONNECTING PIPING
(1) Cut a 3-1/8”(80 mm) diameter hole in the wall at the position shown in
the figure.
(2) When cutting the wall hole at the inside of the wall hook bracket, cut
the hole to a point of intersection of center marks.
When cutting the wall hole at the outside of the wall hook bracket, cut
the hole at a point of 10mm below.
(3) Cut the hole so that the outside end is lower (3/16” to 3/8” (5 to 10
mm)) than the inside end.
(4) Always align the center of the wall hole. If misaligned, water leakage
will occur.
(5) Cut the wall pipe to match the wall thickness, stick it into the wall cap,
fasten the cap with vinyl tape, and stick the pipe through the hole. (The
connection pipe is supplied in the installation set.)
(6) For left piping and right piping, cut the hole a little lower so that drain
water will flow freely.

INSTALLING THE WALL HOOK BRACKET
(1) Install the wall hook bracket so that it is correctly positioned horizon-
tally and vertically. If the wall hook bracket is tiled, water will drip to the
floor.
(2) Install the wall hook bracket so that it is strong enough to withstand
the weight of an adult.
●
Fasten the wall hook bracket to the wall with 6 or more screws through
the holes near the outer edge of the bracket.
●
Check that there is no rattle at the wall hook bracket.
WARNING
If the wall pipe is not used, the cord interconnecting
the indoor and outdoor units may touch metal and
cause electric leakage.

FORMING THE DRAIN HOSE AND PIPE
[Rear piping, Right piping, Bottom piping]
●
Install the indoor unit piping in the direction of the wall hole and bind
the drain hose and pipe together with vinyl tape.
●
Install the piping so that the drain hose is at the bottom.
●
Wrap the pipes of the indoor unit that are visible from the outside with
decorative tape.
[For Left rear piping, Left piping]
Interchange the drain cap and the drain hose.

CAUTION
Insert the drain hose and drain cap into the drain port, mak-
ing sure that it comes in contact with the back of the drain
port, and then mount it. If the drain hose is not connected
properly, leaking will occur.
•
Attach the Insulation (Drain hose) to the drain hose.
CAUTION
CAUTION
(1)
In order to align the drain hose and drain cap, be
sure to insert securely and vertically. Incline inser-
tion will cause water leakage.
(2)
When inserting, be sure not to attach any material
besides water. If any other material is attached, it
will cause deterioration and water leakage.
(3)
After removing drain hose, be sure not to forget
mounting drain cap.
(4)
Be sure to fix the drain hose with tape to the bottom
of piping.
(5)
Prevent drain water frozen under low tempera-
ture environment.
When installing indoor unit's drain hose outdoors, necessary
measure for frost protection should be taken to prevent drain
water frozen.
• Under low temperature environment (when outdoor tem-
perature under 32 °F), after cooling operation is executed,
water in the drain hose could be frozen.
Once drain water is frozen, the drain hose will be blocked
and water leakage may be resulted for indoor unit.
