6-55. Selecting the Installation Site
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.
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 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
I
nstructions packed with the outdoor unit.
allow room for mounting the remote controller about 3.3ft. (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.
