3.3.4. Forming the drain hose and pipe
CAUTION
In order to align the drain hose and drain cap, be sure to insert securely and vertically.
Incline insertion will cause water leakage.
When inserting, be sure not to attach any material besides water. If any other material
is attached, it will cause deterioration and water leakage.
After removing drain hose, be sure not to forget mounting drain cap.
Be sure to
fi
x the drain hose with tape to the bottom of piping.
[Rear piping, Right piping, Bottom piping]
(1) Install the indoor unit piping in the direction of the wall hole and bind the drain hose
and pipe together with vinyl tape.

(2) Install the piping so that the drain hose is at the bottom.
(3) Wrap the pipes of the indoor unit that are visible from the outside with decorative
tape.
[For Left rear piping, Left piping]
(1) Interchange the drain cap, insulation and the drain hose.

Align the marks.
(3) Bend the connection piping at the bend radius of 70 mm or more and install no more
than 35 mm from the wall.
3.3. Installing the unit
WARNING
Install the air conditioner in a location which can withstand a load of at least 5 times the
weight of the main unit and which will not amplify sound or vibration. If the installation
location is not strong enough, the indoor unit may fall and cause injuries.
If the job is done with the panel frame only, there is a risk that the unit will come loose.
Please take care.
3.3.1. Determining the piping direction
The piping can be connected in the 5 directions indicated by
1
,
2
,
3
,
4
, and
5
in (Fig. A).
When the piping is connected in direction
2
or
5
, cut along the piping groove in the
side of the front cover with a hacksaw.
When connecting the piping in direction
3
, cut a notch in the thin wall at the front bot-
tom of the front cover.

3.3.2. Installing the wall hook bracket
CAUTION
Install the wall hook bracket level, both horizontally and vertically.
(1) Install the wall hook bracket so that it is correctly positioned horizontally and
vertically. If the wall hook bracket is tiled, water will drip to the
fl
oor.
(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.

3.3.3. Cutting the hole in the wall for the connecting piping
WARNING
If the wall pipe is not used, the cable interconnecting the indoor and outdoor units may
touch metal and cause electric leakage.
(1) Cut a 80 mm diameter hole in the wall at the position shown in Fig. B.
(2) When cutting the wall hole at the inside of the wall hook bracket, cut the hole within
the range of the left and right center marks 40 mm below the wall hook bracket.
When cutting the wall hole at the outside of the wall hook bracket, cut the hole at
least 10 mm below over.
(3) Cut the hole so that the outside end is lower (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. B)
(6) For left piping and right piping, cut the hole a little lower so that drain water will
fl
ow
freely. (Fig. B)
