5. SELECTING THE MOUNTING POSITION

Decide the mounting position with the customer as follows:
(1) Install the indoor unit level on a strong wall which is not subject to vibration.
(2) The inlet and outlet ports should not be obstructed : the air should be able to blow all
over the room.
(3) Install the unit a dedicated electrical branch circuit.
(4) Do not install the unit where it will be exposed to direct sunlight.
(5) Install the unit where connection to the outdoor unit or branch box is easy.
(6) Install the unit where the drain pipe can be easily installed.
(7) Take servicing, etc. into consideration and leave the spaces shown in [6.1. Installation
dimensions]. Also install the unit where the fi lter can be removed.
Correct initial installation location is important because it is diffi cult to move unit after it is installed.
Select installation locations that can properly support the weight of the indoor. Install
the units securely so that they do not topple or fall.
Do not install the unit in the following areas:
• Area with high salt content, such as at the seaside. It will deteriorate metal parts,
causing the parts to fail or the unit to leak water.
• Area fi lled with mineral oil or containing a large amount of splashed oil or steam,
such as a kitchen.
It will deteriorate plastic parts, causing the parts to fail or the unit to leak water.
• Area that generates substances that adversely affect the equipment, such as
sulfuric gas, chlorine gas, acid, or alkali.
It will cause the copper pipes and brazed joints to corrode, which can cause
refrigerant leakage.
• Area that can cause combustible gas to leak, contains suspended carbon fi bers or
fl ammable dust, or volatile infl ammables such as paint thinner or gasoline.
If gas leaks and settles around the unit, it can cause a fi re.
• Area where animals may urinate on the unit or ammonia may be generated.
Do not use the unit for special purposes, such as storing food, raising animals, growing
plants, or preserving precision devices or art objects.
It can degrade the quality of the preserved or stored objects.
Do not install where there is the danger of combustible gas leakage.
Do not install the unit near a source of heat, steam, or fl ammable gas.
Install the unit where drainage does not cause any trouble.
Install the indoor unit, outdoor unit, branch box , power supply cable, transmission
cable, and remote control cable at least 1 m away from a television or radio receivers.
The purpose of this is to prevent TV reception interference or radio noise. (Even if
they are installed more than 1 m apart, you could still receive noise under some signal
conditions.)
If children under 10 years old may approach the unit, take preventive measures so
that they cannot reach the unit.
Install the indoor unit on the wall where the height from the fl oors more than 1800 mm.

6.2. Indoor unit piping direction

The piping can be connected in the 7 directions in the fi gure. When the piping is con-
nected in direction 2, 3, 4 or 5, cut along the piping groove in the side of the front
panel with a hacksaw.

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

(1) Cut a 80 mm diameter hole in the wall at the position shown in the fi gure.
(2) When cutting the wall hole at the inside of the wall hook bracket, cut the hole to a point of
intersection of center marks.
When cutting the wall hole at the outside of the wall hook bracket, cut the hole at a
point of 10 mm below.
(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.
(6) For left piping and right piping, cut the hole a little lower so that drain water will fl ow
freely.

If the wall pipe is not used, the cable interconnecting the indoor unit(s) and outdoor unit
or branch box may touch metal and cause electric discharge.

6.4. Installing the wall hook bracket

(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 support the weight of the
unit.
● 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.
