(1) Install the indoor unit on a place having a suf

cient strength so that it withstands

against the weight of the indoor unit.

(2) The inlet and outlet ports should not be obstructed; the air should be able to blow all

over the room.

(3)  Leave the space required to service the air conditioner.
(4)  Install the unit where connection to the outdoor unit is easy.
(5)  Install the unit where the connection pipe can be easily installed.
(6)  Install the unit where the drain pipe can be easily installed.
(7)  Install the unit where noise and vibrations are not ampli

ed.

(8) Take servicing, etc., into consideration and leave the spaces. Also install the unit

where the

lter can be removed.

(9) Do not install the unit where it will be exposed to direct sunlight.

3.3. Installation 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.

The piping can be connected in the 7 directions indicated by

3.3.1. Installing the wall hook bracket

WARNING

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 (13/32 in. (10 mm) dia.) into the wall at the

wall hook bracket holes.

(Allow the anchor bolts to stick out at least 23/32 in. (18 mm) from the wall. Use 2
bolts for

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 con

rming, using the level indicator,

that the clamp is horizontal.

WARNING

Install the wall hook bracket level, both horizontally and vertically. If the wall hook
bracket is tilted, wa ter will drip to the

oor.

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 suf

ciently

strong so that the wall can support the weight.

3.3.2. Cutting the hole in the wall for the connecting piping

WARNING

If the wall pipe is not used, the cable may touch metal and cause electric leakage.

(1) Cut a 3-5/32 in. (80 mm) diameter hole in the wall at the position shown in Fig. B.
(2) For

Rear piping and

Left rear piping, cut the hole to a point of intersection of

center marks (Fig. B).

For

Right piping and

Left piping, cut the hole at least 13/32 in. (10 mm) below

the holes for the rear piping and left rear piping for the drain water to

ow freely (Fig. B).

For

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 3/16 to 13/32 in. (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

ow freely.
