15 Functions 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.
COMFORT
AIRFLOW
Operation
The airflow direction is upward while in cooling and dry operation, and downward while in heating
operation. This function prevents cold or warm air from blowing directly on the occupants in the
room.
When COMFORT AIRFLOW operation is set, or the combination use of COMFORT AIRFLOW
operation and INTELLIGENT EYE operation is set, the airflow rate will be set to AUTO.
If the up and down airflow direction is selected, COMFORT AIRFLOW operation will be canceled.
Priority is given to the function of whichever button is pressed last.
