SELECTING THE INSTALLATION SITEIndoor UnitAVOID:Areas where leakage of flammable gas may be expected.Places where large amounts of oil mist exist.Direct sunlight.Locations near heat sources which may affect the performance of the unit.Locations where external air may enter the room directly. This may cause “condensation” on the air-dischargeports, causing them to spray or drip water.Locations where the remote controller will be splashed with water or affected by dampness or humidity.Installing the remote controller behind curtains or furniture.Locations where high-frequency emissions are generated.Places where blocks air passages.Places where the false ceiling is not noticeably on an incline.DO:Select an appropriate position from which every corner of the room can be uniformly cooled.Select a location where the ceiling is strong enough to support the weight of the unit.Select a location where tubing and drain pipe have the shortest run to the outdoor unit.Allow room for operation and maintenance as well as unrestricted airflow around the unit.Install the unit within the maximum elevation difference above or below the outdoor unit and within a total tubinglength (L) from the outdoor unit as detailed in Table 1-1.Allow room for mounting the remote controller about 1 m off the floor, in an area that is not in direct sunlight or inthe flow of cool air from the indoor unit.Places where optimum air distribution can be ensured.Places where sufficient clearance for maintenance and service can be ensured.When moving the unit during or after unpacking, make sure to lift it by holding its lifting lugs. Do notexert any pressure on other parts, especially the refrigerant piping, drain piping and flange parts.If you think the humidity inside the ceiling might exceed 30°C and RH 80%, reinforce the insulation onthe unit body. Use glass wool or polyethylene foam as insulation so that it is no thicker than 10 mm andfits inside the ceiling opening.CAUTIONIndoor Unit
