3 Selection of installation place
Avoid installing in the following places
Select a location for the indoor unit where the cool or warm air will circulate evenly.
Avoid installation in the following kinds of locations.
• Saline area (coastal area)
• 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.
• Places where iron or other metal dust is present. If iron or other metal dust adheres to or collects on the interior
of the air conditioner, it may spontaneously combust and start a fire.
• 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.
Installation under high-humidity atmosphere
In some cases including the rainy season, especially inside of the ceiling may become high-humidity atmosphere
(dew-point temperature: 23 °C or higher).
1. Installation to inside of the ceiling with tiles on the roof
2. Installation to inside of the ceiling with slated roof
3. Installation to a place where inside of the ceiling is used for pathway to intake the fresh air
4. Installation to a kitchen
• In the above cases, additionally attach the heat insulator to all positions of the air conditioner, which come to
contact with the high-humidity atmosphere. In this case, arrange the side plate (Check port) so that it is easily
removed.
• Apply also a sufficient heat insulation to the duct and connecting part of the duct.
[Reference] Condensation test conditions
Indoor side:
27 °C dry bulb temperature
24 °C wet bulb temperature
Air volume: Low air volume, operation time 4 hours
