5.1.5. OPERATION PROCEDURE FOR SWING LOUVER ADJUSTMENT
Setting 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 mark “ ” is moving, it indicates the
operation of the louver continuously.
2. When the swinging operation of the louver is not required,
press the SWING LOUVER switch again. The louver is
stopped at an angle indicated by the direction of the mark
“ ”.
3. Discharge air angle is fixed (at 20° for RCI series and 40°
for RCD series) during start-up of heating operation and
defrosting operation when thermostat is ON. When the
outlet air temperature exceeds approximately 30 °C, the
louvers start to swing.

Fixing the louver
1. In the case of cooling and dry operation, discharge air
angle can be changed at 5 positions. In the case of heating
operation, it can be changed at 7 positions
2. To fix the louver position, first press the SWING LOUVER
switch to start the louver swinging, and then press the
SWING LOUVER switch again when the louver reaches
the required position.
3. Discharge air angle is fixed (at 20° for RCI series and 40°
for RCD series) during start-up of heating operation and
defrosting operation when thermostat is ON. When the
outlet air temperature exceeds approxima-tely 30 °C, the
swing louvers activate.
4. When the louvers are fixed at an angle 55° RCI, 65° RCD
or 70° both during heating operation and the operation
mode is changed to cooling operation, louvers will be
automatically fixed at an angle 45° RCI, 60° RCD.

NOTE:
There exists a time lag between the actual angle of the
louver and the liquid crystal indication. When the SWING
LOUVER switch is pressed, the louver will not stop
immediately. The louver will move one extra swing.
If the louvers are moced due to cleaning or for any
reason, setAuto Seting mode to take the four louvers in
the same position.
Do not turn the air louver by hand. Otherwise the louver
mechanism would be damaged (in all units).

CAUTION
Wall Type (RPK):
Adjust the vertical louvers by hand to discharge air in the required
direction.
Do not swing 1 blade at left side and 2 blade at right side of the
vertical deflection.
Automatic Setting of louver
When the unit operation is stopped, two air louvers are stopped at
closing position automatically.
Ceiling Type (RPC):
The vertical deflector consists of four sets of deflectors. Adjust the
vertical louvers by hand to discharge air in the required direction.

NOTE:
For models without automatic swing louver the above
indications are not available through R.C.S.
The swing Louver should be adjusted by hand in this case.
