Power-Airflow
Flap
The large flap sends a large volume of air downward to the floor and provides an optimum control in
cooling, dry, and heating operation.
<Cooling / Dry>
During cooling or dry operation, the flap retracts into the indoor unit. Then, cool air can be blown far
and distributed all over the room.
<Heating>
During heating operation, the large flap directs airflow downward to spread the warm air to the
entire room.
Wide-Angle
Louvers
The louvers, made of elastic synthetic resin, provide a wide range of airflow that guarantees
comfortable air distribution.
Auto-Swing The following table explains the auto-swing process for cooling, dry, heating, and fan:
