Auto-Swing
Power-airflow
Dual Flaps
The large flaps send a large volume of air downwards to the floor. The flap provides an optimum
control area in cooling, heating and dry mode.
Heating Mode
During heating mode, the large flap enables direct warm air straight downwards. The flap
presses the warm air above the floor to reach the entire room.
Cooling Mode
During cooling mode, the flap retracts into the indoor unit. Then, cool air can be blown far and
pervaded all over the room.
Wide-Angle
Louvers The louvres, made of elastic synthetic resin, provide a wide range of airflow that guarantees a
comfortable air distribution.

swing motion is such that it turns counterclockwise, starting from the right upper point as
viewed to the front side of the indoor unit.
