2. Installation Site Selection

2-1. Indoor Unit

AVOID:

●

direct sunlight.

●

nearby heat sources that may affect performance of the

unit.

●

areas where leakage of flammable gas may be expected.

●

placing or allowing any obstructions near the A/C inlet or

outlet.

●

installing in rooms that contain instant-on (rapid-start)

fluorescent lamps. (These may prevent the A/C from

receiving signals.)

●

places where large amounts of oil mist exist.

●

installing in locations where there are devices that

generate high-frequency emissions.

DO:

●

select an appropriate position from which every corner 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. (Fig. 1)

●

allow room for operation and maintenance as well as

unrestricted air flow around the unit. (Fig. 2)

●

install the unit within the maximum elevation difference

(H1, H2, H3, H4) above or below the outdoor unit and

within a total tubing length (L1+L2+L3, L1+L2+L3+L4)

from the outdoor unit as detailed in Table 3 and Fig. 3a.
