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 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

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

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)

3.3.4. Forming the drain hose and pipe

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.
