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.This may cause “condensation” on the air discharge ports,causing them to spray or drip water.● 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.● locations on the outside or in humid areas like swimmingpools.● locations in areas with danger of explosion, with aggressiveair or with extreme high dust exposure.DO:● select a location in frost-free indoor areas only.● select a location where the ceiling is strong enough tosupport the weight of the unit.● select a location where the unit can be installed as close aspossible to the wall and as flush as possible to the top of thedoor.● 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 installationmanual 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 or in the flowof cool air from the indoor unit.Fig. 2-1 shows the unit in freely suspended installation.Fig. 2-1Ceiling mounting kitInlet grilleInspection coverDoorframeWall Electrical connections
