6013.8 Powerful Operation• To achieve the setting temperature quickly.• When powerful operation is set, the setting temperature will be automatically decreased 3°C internally againstthe present setting temperature (Lower temperature limit: 16°C).• This operation automatically running under Shi fan speed (Cooling), Lo- Fan Speed (Soft Dry) is applicable forC9PK and C12PK only.• 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.• Powerful operation stops when:o Powerful/Quiet button is pressed againo Powerful operation has operate for 15 minutes.o Stopped by OFF/ON operation button.o Timer OFF activateso Operation mode is changed13.9 Quiet Operation(For Cooling Operation or cooling region of Soft Dry Operation)• To provide quiet cooling operation condition.• Once the Quiet Operation is set at the remote control, the Quiet LED brightness will be dimmed. The sound levelwill reduce around 2dB(A) for Lo fan speed or 3dB(A) for Hi/Me fan speed against the present operation soundlevel.• Dew formation become severe at Quite Lo Cool, therefore Quiet Lo cool operated only for 1 hour 30 minutes(1 hour QLo, 30 minutes QLo + 80rpm)(for C9PK and C12PK) and Quiet Lo cool operated only 1 hour30 minutes (1 hour QLo, 30 minutes QLo + 50 rpm) (for C18PK, C24PK and C28PK).• Manual Airflow Direction:o RPM control during Lo cool(For C9PK and C12PK)(For C18PK, C24PK and C28PK)
