15 Function and Control
1.3 Airflow Direction Control
Power-Airflow
Dual Flaps 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:
3-D Airflow Alternative repetition of vertical and horizontal swing motions enables uniform air-conditioning of
the entire room.
When the horizontal swing and vertical swing are both set to automatic operation, the airflow
becomes 3-D airflow. The horizontal and vertical swing motions are alternated and the airflow
direction changes in the order shown in the following diagram.
(1) The louvers move from the right to the left.
(2) The flaps move downward.
(3) The louvers move from the left to the right.
(4) The flaps move upward.
