3.3. Installing the unit

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 connect-
ed according to the figure
and table. When the piping
is connected in direction Right
outlet
(B), (C), (D) or (E), cut
(B)
along the piping groove in
the side of the front panel
with a hacksaw.
3.3.2 Installing the wall hook bracket
Install the wall hook bracket level, both horizontally and vertically. If the wall hook
bracket is tilted, wa ter will drip to the floor.
As the weight of the indoor unit is 33 to 40 lbs (15 to 18 kg), it should be installed after
properly examining the place where it is in tended to be in stalled. If the place is not
strong enough, a plank or girder should be used to make the place sufficiently strong so
that the wall can support the weight.
• Remove the wall hook bracket
from the indoor unit. (Remove
2 screws).
• Refer to figure below for the
installation hole positions of
the wall hook bracket.
• Before fastening the wall hook bracket to the wall with the screws, level it by tapping the
hook at the center of bracket to the wall with the handle of a screwdriver.

WARNING
(1) Fasten the wall hook
bracket to the wall with
5 or more screws and
anchor bolts through
the holes near the outer
edge of the bracket.
(Do not install the wall
hook bracket at only 1
place or at an angle.)
(2) For a concrete wall, embed anchor bolts (3/8 in (10 mm) dia.) into the wall at the wall
22 ft
hook bracket holes.
(7 m)
(Allow the anchor bolts to stick out at least 11/16 in (18 mm) from the wall. Use 2
bolts for flat concrete wall and 4 bolts for blister concrete wall.)
(3) Install the nuts to the anchor bolts through the wall hook bracket.
(4) Finally tighten the bolts and wood screws after confirming, using the level indicator,
that the clamp is horizontal.
3.3.3 Cutting the hole in the wall for the connecting piping
(1) Cut a hole in the wall at the posi-
tion shown in the following.
(2) Cut the hole so that the outside
end is lower (3/16 to 3/8 in (5 to 10
mm)) than the inside end.
(3) Always align the center of the wall
hole. If misaligned, water leakage
will occur.
(4) Cut the wall pipe to match the wall
(5 (122)
thickness, stick it into the wall cap,
or more)
fasten the cap with vinyl tape, and
stick the pipe through the hole.

or more
(5) For left piping and right piping, cut the hole a little lower so that drain water will flow
freely.
Attach the wall pipe
WARNING
If the wall pipe is not used, the
cable interconnecting the indoor
and outdoor units may touch
metal and cause electric leakage.
3.3.4 Forming the drain hose and pipe
Insert drain hose and drain cap securely. Drain should slope down to avoid water leak-
age.
When inserting the drain hose, no other material than water should be applied. Applica-
tion of other material than water will cause deterioration of the hose, and may cause
water leakage.
After you remove a drain hose, be sure to attach the drain cap.
When you secure the piping and drain hose with tape, arrange the drain hose so that it
is at the bottom of the piping.

For drain hose piping in low temperature environment, you need to apply freeze protec-
(E)
tion to prevent a frozen drain hose.
After cooling operation is performed in low temperature environment, (when outdoor

[For (A) Rear piping, (B) Right piping and (C) 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 pipe of the indoor unit
that visible from the outside
with decorative tape.
(4) For right or bottom outlet
piping, cut off the piping outlet
cutting groove with a hacksaw.
