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.
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. De lo contrario, su
mecanismo puede sufrir daños (en todas las unidades).
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.
