2. When the swinging operation of the louver is not required, press the SWING
LOUVER switch again. The louver stops at the angle indicated by the

direction of the "
3. The discharge air angle is fixed at 20° for the RCI series and 40° for RCD
series during the start-up of the heating and defrosting operation when the
thermostat is on. When the outlet air temperature exceeds approximately 30
°C, the louvers start to swing.
1. For COOL and DRY modes, the discharge air angle can be changed to
5 different positions. For the heating operation, it can be changed to 7
positions.
2. To fix the louver position, first press the SWING LOUVER switch to start the
louver swinging, and then press again when the louver reaches the required
position.
3. The discharge air angle is fixed at 20° for the RCI series and 40° for the RCD
series during the start-up of the heating and defrosting operation when the
thermostat is on.When the outlet air temperature exceeds approximately 30
°C, the louvers start to swing.
When the louvers are fixed at an angle of 55° for RCI, 65° for RCD or 70° for
both during the heating operation, and the operation mode is changed to cooling,
the louvers will be automatically fixed at an angle of 45° for RCI or 60° for RCD.

NOTE:
There is a time lag between the actual angle of the louver and the indication
on the liquid crystal display. When the SWING LOUVER switch is pressed,
the louver will not stop immediately. The louver will move one extra swing.
If the louvers are moved when cleaning or for any other reason, select the
auto setting mode to move the four louvers to the same position.
Do not turn the air louver by hand. The louver mechanism may be damaged if moved
(in all units).

”
Adjust the vertical louvers by hand to discharge air in the required direction.
Do not swing blade 1 to the left and blade 2 to the right of the vertical louvering.
Automatic setting of the louver:
”
When the unit is not in operation, two air louvers stop automatically in the closed
position.
Ceiling-mounted type (RPC):
”
