3. 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.
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 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 dete-
riorate 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 ammo-
•
nia may be generated.
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 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.
2.3. Accessories
WARNING
For installation purposes, be sure to use the parts sup-
•
plied by the manufacturer or other prescribed parts.
The use of non-prescribed parts can cause serious ac-
cidents such as the unit falling, water leakage, electric
shock, or fire.
The following installation parts are furnished. Use them as
•
required.
Keep the Installation Manual in a safe place and do not
•
discard any other accessories until the installation work has
been completed.
