– 84 –– 4 –EN4 Selection of installation placeAvoid 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.• Locations where inside the ceiling is used as route for outside air.• Saline area (coastal area)• Locations with acidic or alkaline atmospheres (such as areas with hot springs, factories where chemicals orpharmaceuticals are made and places where the exhaust air from combustion appliances will be sucked into theunit).Doing so may cause the heat exchanger (its aluminum fins and copper pipes) and other parts to becomecorroded.• 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 heatexchanger to be generated, the plastic parts to be damaged, the heat insulators to peel off, and other suchproblems to result.• Places where iron or other metal dust is present. If iron or other metal dust adheres to or collects on the interiorof 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 partsto 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 willbe disrupted (a disruption of the air flow may cause the air conditioner’s performance to deteriorate or the unit toshut 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, precisioninstruments 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, medicalequipment 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.)• 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 spaceKeep the space necessary for installation and service.REQUIREMENTThe check port should be 23.6" × 23.6" (600 × 600 mm).Unit: in (mm) Installation under atmosphere of the high humidityAlthough it has been confirmed that no trouble occurs on the unit, there is a fear of drip of the water if operationunder high humidity condition continues.In some cases including the rainy season, especially inside of the ceiling may become high-humidity atmosphere(dew-point temperature: 86 °F (30 °C) (humidity: 80%) 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 inside of the ceiling with kitchen.• In the above cases, additionally attach the heat insulator (Glass wool, etc.) to all positions of the airconditioner, which come to contact with the high-humidity atmosphere.In this case, arrange the side plate (Service panel) so that it is easily removed.• Apply also heat insulating a sufficient thickness 0.39" (10 mm) or more to the duct and connecting part ofthe duct.7.9" (200) or moreElectrical control boxCheck portCheck port39.4" (1000) or more23.6"(600)7.9" (200)23.6" (600)2.0" (50)or more3.9" (100) or moreService panelDuct7-EN 8-EN
