Selection of installation place

Upon approval of the customer, install the air conditioner in a place that satisfies the
following conditions
• Place where the unit can be installed horizontally.
• Place where a sufficient servicing space can be ensured for safety maintenance and check.
• Place where drained water will not cause any problem.
Avoid installing in the following places
• Place exposed to air with high salt content (seaside area), or place exposed to large quantities of sulfide gas (hot
spring).
(Should the unit be used in these places, special protective measures are needed.)
• A restaurant kitchen where a lot of oil is used or place near machines in a factory (Oil adhering to the heat
exchanger and resin part (fan) in the indoor unit may reduce the performance, generate mist or dew drop, or
deform or damage resin parts.)
• 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.
• Place where organic solvent is used nearby.
• Place close to a machine generating high frequency.
• Place where the discharged air blows directly into the window of the neighbour house. (Outdoor unit)
• Place where noise of the outdoor unit is easily transmitted.
(When install the outdoor unit on the boundary with the neighbour, pay due attention to the level of noise.)
• Place with poor ventilation. (Before air duct installation, check whether value of air volume, static pressure and
duct resistance are correct.)
• Do not use the air conditioner for special purposes such as preserving food, precision instruments, or art objects,
or where breeding animals or growing plants are kept. (This may degrade the quality of preserved materials.)
• Place where any of high-frequency appliances (including inverter devices, private power generators, medical
equipment, and communication equipment) and inverter-type fluorescent light is installed.
(A malfunction of the air conditioner, abnormal control, or problems due to noise to such appliances / equipment
may occur.)
• When the wireless remote controller is used in a room equipped with an inverter-type fluorescent light or at a
place exposed to direct sunlight, signals from the remote controller may not be received correctly.
• Place where organic solvent is used.
• Place where special spray is 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
• 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.
