3. INSTALLATION WORK
Correct initial installation location is important because it is dif
fi
cult to move unit after it is
installed.
]1
3.1. Selecting an installation location
Decide the mounting position together with the customer as follows.
WARNING
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.
CAUTION
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 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 in
fl
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, 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 suf
fi
cient 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 ampli
fi
ed.
(8) Take servicing, etc., into consideration and leave the spaces. Also install the unit
where the
fi
lter can be removed.
(9) Do not install the unit where it will be exposed to direct sunlight.
