select a location where tubing and drain hose have the
shortest run to the outside. (Fig 1a)
select a location that will hold the weight of the unit.
select an appropriate position from which every corner of
the room can be uniformly cooled. (High on a wall is best)
allow room for operation and maintenance as well as
unrestricted air flow around the unit. (Fig 1b)
AVOID:
places where large amounts of oil mist exist.
areas where leakage of flammable gas may be expected.
nearby heat sources that may affect performance of the
unit.
direct sunlight.

To prevent abnormal heat genera-
tion and the possibility of fire, do
not place obstacles, enclosures
and grilles in front of or sur-
rounding the air conditioner in a
way that may block air flow.

This outdoor unit requires no refrigerant
charge up to the maximum limit for the
maximum allowable tubing length of 7.5m
