INSTALLATION OF
REMOTE CONTROLLER
5.1.5. PROCEDURE FOR SETTING THE SWING LOUVER
1. When the SWING LOUVER switch is pressed, the swing louver
starts its operation. The range of the angle of swing is approximately
70° from the horizontal to the vertical position. When the "
symbol is moving, this indicates the continuous operation of the
louver.
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).
• Wall-mounted type (RPK):
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):
The vertical louver consists of four sets of louvers. Adjust the vertical louvers by
hand to discharge air in the required direction.

NOTE:
The models which do not have a swing louver will not show the above
indications on the remote control. In this case, the louver must be
adjusted manually.
