3. INSTALLATION WORK
3.1. Selecting an installation location
Especially, the installation place is very important for the split type air conditioner be-
cause it is very dif
fi
cult to move from place to place after the
fi
rst installation.
WARNING
Select installation locations that can properly support the weight of the indoor. 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
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, outdoor 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.)
Take precautions to prevent the unit from falling.
Decide the mounting position with the customer as follows:
(1) Install the indoor unit in a location having suf
fi
cient 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.
