FORMING THE DRAIN HOSE AND PIPE
(1) Install the wall hook bracket so that it is correctly positioned hori-
zontally and vertically. If the wall hook bracket is titled, water will
drip to the floor.
(2) Install the wall hook bracket so that it is strong enough to with-
stand 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.

[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. (Fig. 3)
●
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.

Removal method of drain
hose
●
Remove the screw at the left of
drain hose and pull out drain
hose.
Installation method of
drain hose
●
Vertically insert the drain hose
toward the inside, so that the
drain fixture (blue) can accu-
rately align with the screw hole
around the drain cock.
After inserting and before re-
placing, please reinstall and fix
the removed screws.
●
Be sure to install around the drain hose connector.
●
As the screw is inside, be sure to use screwdriver treated with magnet.

CAUTION
(1)
In order to align the drain hose and drain cap, be
sure to insert securely and vertically. Incline in-
sertion will cause water leakage.
(2)
When inserting, be sure not to attach any mate-
rial 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 bot-
tom 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
temperature 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.
(1) Cut a 2-9/16” (65 mm) diameter hole in the wall at the position shown
in (Fig. 1).
(2) When cutting the wall hole at the inside of the installation frame, cut
the hole within the range of the left and right center marks of the
installation frame.
When cutting the wall hole at the outside of the installation frame,
cut the hole at least 3/8” (10 mm) lower.
(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.) (Fig. 5)
(6) For left piping and right piping, cut the hole a little lower so that
drain water will flow freely. (Fig. 1)
