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.
The piping can be connected in the 7 directions indicated by
2 Right
piping
1 Rear piping
3 Bottom piping
3.3.1. Installing the wall hook bracket
If the wall pipe is not used, the cable interconnecting the indoor and outdoor units may
touch metal and cause electric leakage.
[Installation directly to a wall]
Refer to Fig. A for the installation hole dimensions 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.
(1) Fasten the wall hook bracket to the wall with 6 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 (10 mm dia.) into the wall at the wall hook
bracket holes.
(Allow the anchor bolts to stick out at least 18 mm from the wall. Use 2 bolts for fl at
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 confi rming, using the level indicator,
that the clamp is horizontal.
Install the wall hook bracket level, both horizontally and vertically. If the wall hook
bracket is tilted, wa ter will drip to the fl oor.
As the weight of the indoor unit is 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 suffi ciently strong so that
the wall can support the weight.

3.3.2. Cutting the hole in the wall for the connecting piping
If the wall pipe is not used, the cable 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) For
1
Rear piping and
center marks (Fig. B).
For
Right piping and
2
for the rear piping and left rear piping for the drain water to fl ow freely (Fig. B).
For
6
Center piping, cut a hole in the lower, center section of the wall hook bracket.
(Refer to Fig. A. Do not cut a hole outside of the indoor unit outline.)
(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 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 and center piping, cut the hole a little lower so that
drain water will fl ow freely.

3.3.3. Attach the drain hose
hole
Insert the drain hose and drain cap into the drain port, making 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.
• Wrap the insulation around the drain hose, making sure that there are no gaps.
• Attach the Insulation (Drain hose) to the drain hose.
