5. SELECTING THE MOUNTING POSITION
Decide the mounting position with the customer as follows:
5.1. Indoor unit
(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 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, 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.

6.3. Cutting the hole in the wall for the connecting piping
(1) Cut a 65 mm diameter hole in the wall at the position shown in the following.
(2) Cut the hole so that the outside end is lower (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 thickness, stick it into the wall cap, fasten the cap with
vinyl tape, and stick the pipe through the hole.
(5) For left piping and right piping, cut the hole a little lower so that drain water will fl ow
freely.
