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.
● places where large amounts of oil mist exist.
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 unre-
stricted air flow around the unit. (Fig. 2)
● install the unit within the maximum elevation difference (H)
above or below the outdoor unit and within the maximum tub-
ing length (L) from the outdoor unit as detailed in Table 3 and
Fig. 3a.
● install the indoor unit more than 3.3' (1 m) away from any
antenna or power lines or connecting wires used for television,
radio, telephone, security system, or intercom. Electrical noise
from any of these sources may affect operation.
