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.
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 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.

Installation space
Reserve sufficient space required for installation or service work.
250 or more

If height of ceiling exceeds 3.5 m, hot air becomes difficult to reach the floor surface, and then the change of setup
of high ceiling is necessary.
For the change method of high ceiling, refer to the application control, "Installing indoor unit on high ceiling" in this
Manual.

The lighting time of the filter sign (notification of filter cleaning) on the remote controller can be changed according
to installation conditions.
When it is difficult to obtain satisfactory heating due to location place of the indoor unit or the structure of the room,
the detection temperature of heating can be raised.
For change the setup time, refer to the application control, "Filter sign setting" and "To secure better effect of
heating" in this Manual.
■
In case of wireless type
Decide the position which remote controller is operated and the installation place.
And then refer to the Installation Manual of the wireless remote controller kit sold separately.
(The signal of the wireless type remote controller can be received within approx. 8 m. This distance is a criterion
and varies a little according to capacity of the battery)
• To prevent malfunction, select a place where is not affected by a fluorescent lamp or direct sunlight.
• Two wireless-type indoor units can be set in a room.
