SELECTION OF INSTALLATION PLACE

Select a location for the indoor unit where the cool or warm air will circulate evenly.
Avoid installation in the following kinds of locations.
• Locations with acidic or alkaline atmospheres (such as areas with hot springs, factories where chemicals or
pharmaceuticals are made and places where the exhaust air from combustion appliances will be sucked into the
unit).
Doing so may cause the heat exchanger (its aluminum fins and copper pipes) and other parts to become corroded.
• Locations with atmospheres with mist of cutting oil or other types of machine oil.
Doing so may cause the heat exchanger to become corroded, mists caused by the blockage of the heat exchanger
to be generated, the plastic parts to be damaged, the heat insulators to peel off, and other such problems to result.
• Locations where vapors from food oils are formed (such as kitchens where food oils are used).
Blocked filters may cause the air conditioner's performance to deteriorate, condensation to form, the plastic parts to
be damaged, and other such problems to result.
• Locations near obstructions such as ventilation openings or lighting fixtures where the flow of the blown air will be
disrupted (a disruption of the air flow may cause the air conditioner's performance to deteriorate or the unit to shut
down).
• Locations where an in-house power generator is used for the power supply.
The power line frequency and voltage may fluctuate, and the air conditioner may not work properly as a result.
• On truck cranes, ships or other moving conveyances.
• The air conditioner must not be used for special applications (such as for storing food, plants, precision instruments
or art works).
(The quality of the items stored may be degraded.)
• Locations where high frequencies are generated (by inverter equipment, in-house power generators, medical
equipment or communication equipment).
(Malfunctioning or control trouble in the air conditioner or noise may adversely affect the equipment's operation.)
• Locations where there is anything under the unit installed that would be compromised by wetness.
(If the drain has become blocked or when the humidity is over 80%, condensation from the indoor unit will drip,
possibly causing damage to anything underneath.)
• In the case of the wireless type of system, rooms with the inverter type of fluorescent lighting or locations exposed
to direct sunlight.
(The signals from the wireless remote controller may not be sensed.)
• Locations where organic solvents are being used.
• The air conditioner cannot be used for liquefied carbonic acid cooling or in chemical plants.
• Location near doors or windows where the air conditioner may come into contact with high-temperature, high-
humidity outdoor air.
(Condensation may occur as a result.)
• Locations where special sprays are used frequently.
Ensure that the electrical insulation between the metal parts of structures and metal parts of the air conditioner
complies with the laws and regulations enforced in the country where the air conditioner is installed.
EN-11
CAUTION
When the air conditioner is installed in the following kinds of locations where the ceiling temperature may be 30°C and
the relative humidity may be over 80%, condensation may occur on the outer surfaces of the indoor unit and drip.
Therefore, adhere some heat insulators to the side panels (on four sides) of the indoor unit and surface of the ceiling.
• Kitchens and other locations where high levels of indoor heat are generated
• Locations where the fresh air is supplied through the open space in the ceiling
• Inside ceiling under slate roofs or tiled roofs
Shapes of additional heat insulators (use insulators which are at least 10 mm thick)
