8. INSTALLATION INSTRUCTIONS
To prevent abnormal heat gen-
eration and the possibility of
fire, don’t place obstacles,
enclosures and grilles in front
of or surrounding the air condi-
tioner 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 expect-
ed.
●
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.
●
allow room for operation and maintenance as well as
unrestricted air flow around the unit. (Fig. 2a)
