Dual Louvers
The large louver 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 louver retracts into the indoor unit. Then, cool air can be blown
far and distributed all over the room.
<Heating>
During heating operation, the large louver directs airflow downward to spread the warm air to the
entire room.
Wide-Angle Fins
The fins, made of elastic synthetic resin, provide a wide range of airflow that guarantees
comfortable air distribution.
