3. INSTALLATION WORK
Correct initial installation location is important because it is difficult to move unit after it is
installed.
3.1. Selecting an installation location
Decide the mounting position together with the customer as follows.
Select installation locations that can properly support the weight of the indoor unit.
Install the units securely so that they do not topple or fall.
Do not install the indoor unit in the following areas:
• Area with high salt content, such as at the seaside. It will deteriorate metal parts, caus-
ing 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 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 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, 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 flammable gas.
Install the unit where drainage does not cause any trouble.
Install the indoor unit, power supply cable, transmission cable, and remote controller
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.
Take precautions to prevent the unit from falling.
(1) Install the indoor unit on a place having a sufficient 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 (or RB 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 amplified.
(8) Take servicing, etc., into consideration and leave the spaces. Also install the unit
where the filter can be removed.
(9) Do not install the unit where it will be exposed to direct sunlight.
Application

Supply power to the indoor unit PCB when
the indoor unit is turned off to prevent er-
rors.
For closing the refrigerant system.
Maximum capacity of connectable indoor
units ≤ 8.0 kW.
For refrigerant leak detection.
For connecting the shut off valve kit and
Gas sensor kit to the indoor unit.
For connecting Gas sensor kit
WARNING
CAUTION
Detection range of the occupancy sensor
Do not hit or push the occupancy sensor. This may lead to damage or malfunction.
Do not touch the occupancy sensor. Any scratches or dirt may lead to incorrect detec-
tion.
Do not place large objects near the occupancy sensor. Also keep heating units outside
the sensor's detection area.

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.
Take care.
3.3.1 Determining the piping direction
The piping can be connect-
ed according to the figure
and table. When the piping
is connected in direction

3.3.2 Installing the wall hook bracket
Install the wall hook bracket level, both horizontally and vertically. If the wall hook
bracket is tilted, wa ter will drip to the floor.
As the weight of the indoor unit is 15 to 18 kg, it should be installed after properly exam-
ining 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 sufficiently strong so that the wall can
support the weight.
• Remove the wall hook bracket
from the indoor unit. (Remove
2 screws).
• Refer to figure below for the
installation hole positions 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.
