SELECTING THE INSTALLATION SITE2-1. Indoor 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 theperformance of the unit.● locations where external air may enter the room directly. Thismay cause “sweating” on the air discharge ports, causingthem to spray or drip.● locations where the remote controller will be splashed withwater or affected by dampness or humidity.● installing the remote controller behind curtains or furniture.● locations where high-frequency emissions are generated.DO:● select an appropriate position from which every corner of theroom can be uniformly cooled.● select a location where the ceiling is strong enough tosupport the weight of the unit.● select a location where tubing and drain pipe have theshortest run to the outdoor unit.● allow room for operation and maintenance as well asunrestricted air flow around the unit.● install the unit within the maximum elevation differenceabove or below the outdoor unit and within a total tubinglength (L) from the outdoor unit as detailed in the installationinstructions packed with the outdoor unit.● allow room for mounting the remote controller about 1 m offthe floor, in an area that is not in direct sunlight nor in theflow of cool air from the indoor unit.NOTEAir delivery will be degraded if the distance from the floor to theceiling is greater than 3 m (for D1 type, greater than 3.5 m).* For 45, 56, 73, 106 types
