<In cooling operation>
(This operation controls the fan speed at indoor unit side.)
The indoor fan (cross flow fan) is operated by the phase-
control induction motor. The fan rotates in 5 stages in
MANUAL mode, and in 5 stages in AUTO mode, respec-
tively. (Table 1)

when the louver is inclined downward.
Fan speed and air flow volume broadly
vary with position of louver.
