CAUTION
Arrange the drain pipe for proper drainage from
the unit.
Improper drainage can result in dew-dropping.
This air conditioner has the structure designed to
drain water collected from dew,
which forms on the back of the
indoor unit, to the drain pan.
Therefore, do not store the
power cord and other parts
at a height above the drain
guide.
• For detaching the
indoor unit from the
installation plate pull
the indoor unit toward
you while pushing its
bottom up at the
specified parts.
Fig. 9-2-14
NOTE
If the pipe is bent incorrectly, the indoor unit may
unstably be set on the wall.
After passing the connecting pipe through the pipe
hole, connect the connecting pipe to the auxiliary
pipes and wrap the facing tape around them.
CAUTION
• Bind the auxiliary pipes (two) and connecting
cable with facing tape
tightly. In case of
leftward piping and
rear-leftward piping,
bind the auxiliary
pipes (two) only with
facing tape.
• Carefully arrange pipes so that any pipe does
not stick out of the rear plate of the indoor unit.
• Carefully connect the auxiliary pipes and
connecting pipes to each other and cut off the
insulating tape wound on the connecting pipe
to avoid double-taping at the joint, moreover,
seal the joint with the vinyl tape, etc.
• Since dewing results in a machine trouble,
make sure to insulate both the connecting pipes.
(Use polyethylene foam as insulating material.)
• When bending a pipe, carefully do it not to
crush it.
9-2-5. Piping and Drain Hose Installation
In case of rightward piping
• After scribing slits of the
front cabinet and the rear
panel by a knife or a
marking-off pin, cut them by
a pair of nippers or the like.
Fig. 9-2-12
In case of downward piping
• After scribing the slit of the front
cabinet and slit in the lower part
of the rear panel by a knife or a
marking-off pin, cut them by a
pair of nippers or the like.
Fig. 9-2-13
Left-hand connection with piping
Bend the connecting pipe so that it is laid within
43 mm above the wall surface. If the connecting
pipe is laid exceeding 43 mm above the wall
surface, the indoor unit may unstably be set on the
wall. When bending the connecting pipe, make sure
to use spring bender so as not to crush the pipe.
Bend the connection pipe within a radius of 30 mm.

How to install the front cabinet on the indoor unit
• Install the front cabinet through the opposite
order of “How to remove the front cabinet”.
When the panel is removed and mounted again,
take the following actions:
After fastening the two screws, one each at the left
and right of the air outlet be sure to push the upper
center
Q, right end R, left end S and the lower
center
T of the air outlet, and confirm that no gap
is left between the front cabinet and the rear plate.
• If cooling (dry) operation is made without pushing
the air outlet, dew can be
deposited on the front
cabinet surface. In addition
a gap between the front
cabinet and the rear plate
will become wilder,
spoiling the apperance.
