Airflow Direction Control

Power-Airflow
The large flap sends a large volume of air downward to the floor and provides an optimum control in
Dual Flaps 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
The louvers, made of elastic synthetic resin, provide a wide range of airflow that guarantees
Louvers comfortable air distribution.

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 vertical blades (louvers) move from the right to the left.
(2) The horizontal blades (flaps) move downward.
(3) The vertical blades (louvers) move from the left to the right.
(4) The horizontal blades (flaps) move upward.
COMFORT
The flaps are controlled not to blow the air directly at the people in the room.
AIRFLOW
Operation The airflow direction is upward while in cooling operation, and downward while in heating operation.
This function prevents cold or warm air from blowing directly on the occupants in the room.
