enclosures and grills in front
of or surrounding the air
conditioner in a way that may
block air flow.
AVOID:

direct sunlight.
●
nearby heat sources that may affect performance of
the unit.

areas where leakage of flammable gas may be
expected.
●
places where large amounts of oil mist exist.
DO:
●
select an appropriate position from which every
corner of the room can be uniformly air-conditioned.
(High on a wall is best)
●
select a location that will hold the weight of the unit.
●
select a location where tubing and drain pipe have the
shortest run to the outside.
