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 “sweating” on the air
discharge ports, causing them to spray or drip.
● Iocations where the remote controller will be splashed
with water or affected by dampness or humidity.
● installing the remote controller behind curtains or
furniture.
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 from the outdoor unit as detailed in Table
1-20.
● allow room for mounting the remote controller about
1m off the floor, in an area that is not in direct sunlight
nor in the flow of cool air from the indoor unit.
NOTE
Air delivery will be degraded if the distance from the floor
to the ceiling is greater than 3 m. (for SL type, greater
than 3.5 m)
