SELECTION OF INSTALLATION PLACE
• Install the air conditioner at enough strong place to withstand the weight of the unit.
If the strength is not enough, the unit may fall down resulting in injury.
• Install the air conditioner at a height 8' (2.4 m) or more from the floor.
If you insert your hands or others directly into the unit while the air conditioner operates, it is dangerous because you
may contact with revolving fan or active electricity.
• Do not install the air conditioner in a location subject to a risk of exposure to a combustible gas.
If a combustible gas leaks and stays around the unit, a fire may occur.
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 (turbo fan) in the indoor unit may reduce the performance, generate mist or dew drop,
or deform or damage resin parts.)
• 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 neighbor house. (Outdoor unit)
• Place where noise of the outdoor unit is easily transmitted.
(When install the outdoor unit on the boundary with the neighbor, pay due attention to the level of noise.)
• Place with poor ventilation. (Before air ducting work, check whether value of fan speed, 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 control is used in a room equipped with an inverter-type fluorescent light or at a place
exposed to direct sunlight, signals from the remote control may not be received correctly.
• Place near a door or window exposed to humid outside air (Dew droping may form.).
• Place where special spray is used frequently.
