2. SELECTING THE INSTALLATION SITE

2-1. Indoor Unit
AVOID:
● 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 discharge ports,
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.
● locations on the outside or in humid areas like swimming
pools.
● locations in areas with danger of explosion, with aggressive
air 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 to
support the weight of the unit.
● select a location where the unit can be installed as close as
possible to the wall and as flush as possible to the top of the
door.
● 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 air flow around the unit.
● install the unit within the maximum elevation difference
above or below the outdoor unit and within a total tubing
length (L) from the outdoor unit as detailed in the installation
manual packed with the outdoor unit.
● allow room for mounting the remote controller about 1 m off
the floor, in an area that is not in direct sunlight or in the flow
of cool air from the indoor unit.
