8-1. Installation Site Selection
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 cor-
ner of the room can be uniformly cooled. (High on a
wall is best.)
●
select a location that will hold the weight of the unit.
●
select a location where tubing and drain hose have
the shortest run to the outside.
●
allow room for operation and maintenance as well as
unrestricted air flow around the unit. (Fig. 1)
●
install the unit within the maximum elevation differ-
ence (H1, H2, H3, H4) above or below the outdoor
unit and within a total tubing length (L1+L2+L3+L4)
from the outdoor unit as detailed in Table 1 and Fig. 2.

WARNING
To prevent abnormal heat
