INSTALLATION WORK
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.
21 11
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, causing the parts to fall 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 fall 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 inflammables 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, 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.)
Install the unit where ambient temperature does not reach 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.
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 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.
