7. INSTALLATION INSTRUCTIONS
7-1. Installation Site Selection
To prevent abnormal heat
generation and the possibility
of fire, don’t place obstacles,
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.
●
allow room for operation and maintenance as well as
unrestricted air flow around the unit. (Fig. 1)
●
install the unit within the maximum elevation
difference (H) above or below the outdoor unit and
within a total tubing length (L) from the outdoor unit as
detailed Table 1 and Fig. 2a.
Indoor Unit
Table 1
* If total tubing length becomes 7.5 to 15 (max.) or 7.5 to 20 (max.), charge additional refrigerant (R22) by 15 g/m or 25 g/m.
No additional charge of compressor oil is necessary.
