Manual Fan Speed Control
x Manual fan speed adjustment can be carried out by using the Fan Speed selection button at the remote control.
x There are 3 types of fan speed settings: Lo, Me, Hi.
12.4.4
Indoor Fan Motor rpm Abnormal Control
x Immediate after the fan motor is started, rpm abnormal control is performed every second.
x During fan motor on, if fan motor feedback 2550 rpm or < 50 rpm continuously for 10 seconds, the fan motor
error counter increased; fan motor is then stopped and restarted. If the fan motor error counter increased to 7,
then air conditioner will stop operation.
then air conditioner will stop operation.
12.5 Outdoor Fan Speed Control
x There is only one speed for outdoor fan motor.
x When the air conditioner is turned on, the compressor and the outdoor fan will operate simultaneously.
x Likewise, both compressor and outdoor fan will stop at the same time if the unit is turned off.

12.6 Vertical Airflow Direction Control
12.6.1 Auto
Control
x When the vertical airflow direction is set to Auto using the remote control, the louver swings up and down as
shown in the diagram.
x When stops operation using the remote control, the discharge vent is reset and stops at the closing position.
x During Cooling operation or Soft Dry operation, indoor fan motor may stop to rotate at certain periods. At that
condition, the louver will stop swinging.
12.6.2 Manual
Control
x When the vertical airflow direction is set to Manual using the remote control, the automatic airflow is released and
the airflow direction louver move up and down in the range shown in the diagram.
x The louver can be adjusted by pressing the button to the desired louver position.
x When stop operation using the remote control, the discharge vent is reset, and stop at the closing position.
12.7 Horizontal Airflow Direction Control
The horizontal airflow direction louvers can be adjusted manually by hand.
12.8 Powerful Operation
x To achieve the setting temperature quickly.
x When powerful operation is set, the setting temperature will be automatically decreased 3°C internally against
the present setting temperature (Lower temperature limit: 16°C).
x This operation automatically running under Shi fan speed (Cooling), Lo- Fan Speed (Soft Dry).
x Vertical Airflow Direction:
o In “Manual” setting, the vane will automatically shift down 10° lower than previous setting.
o In “Auto” setting, the vane will automatically swing up and down. However the lower limit will be shifted 10°
downward.
x Powerful operation stops when:
o Quiet/Powerful button is pressed again
o Powerful operation has operate for 15 minutes
o Stopped by OFF/ON operation button.

12.9 Quiet Operation
(For Cooling Operation or cooling region of Soft Dry Operation)

x To provide quiet cooling operation condition.
x Once the Quiet Operation is set at the remote control, the Quiet LED illuminated. The sound level will reduce
around 2dB(A) for Lo fan speed or 3dB(A) for Hi/Me fan speed against the present operation sound level.
x Dew formation become severe at Quite Lo Cool, therefore Quiet Lo cool operated only for 2 hours (1 hour QLo, 1
hour QLo + 80 rpm). After that, it goes back to Lo cool (However Quiet LED remains illuminated).
