3. INSTALLATION WORK
WARNING
Do not move the appliance by holding the indoor unit pipes.
(The stress applied to the pipe joints may cause the flammable gas to leak during
operation.)
Especially, the installation place is very important for the split type air conditioner because
it is very difficult to move from place to place after the first installation.
3.1. Selecting an installation location
WARNING
• Select installation locations that can properly support the weight of the indoor 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.
• Install the units securely so that they do not topple or fall..
CAUTION
• 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 filled 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 where is close to heat sources.
- 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 fibers or
flammable dust, or volatile in flammables such as paint thinner or gasoline.
- If gas leaks and settles around the unit, it can cause a fire.
- 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, grow-
ing plants, or preserving precision devices or art objects. It can degrade the quality
of the preserved or stored objects.
• Install the unit where drainage does not cause any trouble.
• Do not install where there is the danger of combustible gas leakage.
• Do not install the unit near a source of heat, steam, or flammable gas.
• Install the indoor unit, outdoor unit, power supply cable, transmission cable, and
remote control cable at least 40 in (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 40 in (1 m) apart, you could still receive noise
under some signal conditions.)
• Install the unit where ambient temperature does not reach 140 °F (60 °C) or more.
Take a measure such as ventilation for an environment in which heat is retained.
• 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 place where the height from the floor is more than 71
in (1.8 m).
• Use the “Insulation kit for high humidity” (option), when the condition under the roof
is over 80% in humidity and over 86 °F (30 °C) in temperature. Otherwise, there is a
risk of condensation on the ceiling.
Decide the mounting position together with the customer as follows:
(1) Install the indoor unit in a location having sufficient strength to support 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) Locate where the air can be distributed evenly throughout the room by the unit.
(5) Install the unit where connection to the outdoor unit is easy.
(6) Install the unit where the connection pipe can be easily installed.
(7) Install the unit where the drain pipe can be easily installed.
(8) Install the unit where noise and vibration is not amplified.
(9) Take servicing, etc., into consideration and leave the spaces. Also install the unit
where the filter can be removed.

during installation.
• For a 3-way outlet, make sure to perform the Function Setting on the remote control.
Also, make sure to use the optional shutter plate to block the outlet.
• The ceiling height cannot be set in the 3-way outlet mode. Therefore, do not change the
setting in the setting the ceiling height. (Refer to “7. FUNCTION SETTING”)
• When the outlet is shut, be sure to install the optional Air outlet shutter plate kit.
For the details of installation, refer to Installation Manual of kit.
3.3. Installing 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.
• If the job is done with the panel frame only, there is a risk that the unit will come loose.
Take care.
