•Once the compressor is activated, it
does not stop within the first 60 secs.
However, it stops immediately with
remote control stop signal.
Overload Protector
•2-Stage OLP to protect the compressor.

Cooling in operation according to Remote Control setting.
Time Delay Safety Control (3 minutes)
7 minutes Time Save Control
Starting Current Control
Anti-Freezing Control
• If the temperature of the indoor heat exchanger falls
continuously below 2°C for 4 minutes or more, the
compressor turns off to protect the indoor heat exchanger
from freezing. The fan speed setting remains the same.
• Compressor will restart again when the indoor heat
exchanger temperature rises to 10°C (Recovery).
3 minutes waiting of Time Delay Safety Control is valid for
Cooling Operation.
Compressor Reverse Rotation Protection Control
8 Operation Details
8.1. Cooling Mode Operation
• When the compressor is stopped by Remote Control, it restarts after 3 minutes when the Remote Control is turned ON.
• When the setting temperature is reached during cooling operation, the compressor stops and it will not start for 3 minutes.
• The compressor will start automatically if it has stopped for 7 minutes even if the room temperature is between the compressor
ON temperature and OFF temperature.
• When the compressor outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will operate 1.6
second later.
• If the compressor is operating continuously for 5 minutes or longer and the temperature difference between intake air and
indoor heat exchanger is 2.5°C or less for 2 minutes, compressor will stop and restart automatically.
(Time Delay Safety Control is valid)
▲T = Intake air temperature - Indoor heat exchanger temperature
This is to protect reverse rotation of the compressor when there is a instantaneous power failure.

Quiet Operation Control
(For Cooling Mode or cooling region of Soft Dry Mode)
• Purpose of this operation is to provide quite cooling operation compare to normal operation.
• When the Quiet Mode is set at the remote control, Quiet Mode LED illuminates, the sound level will be automatically decreased
2 dB (Lo), decreased 3 dB (Hi, Me), against the present sound level operation.
• Quiet setting of fan speed rpm refer to Indoor Fan Speed Control.
• Dew formation become severe at Quiet Lo cool, therefore Quiet Lo cool is operated only 1h 30 min (1h QLo, 30 min QLo + 50).
After that, it goes back to Lo cool (However Quiet LED remains on).
• Manual Airflow Direction:-
− RPM control during Lo cool
− RPM control during Hi & Me cool
• Auto Airflow Direction:-
• Quiet Mode Operation will stop if:-
− Quiet mode button is pressed again.
− Stopped by ON/OFF switch.
− Timer OFF activates.
− Powerful mode button is pressed.
− When change mode to Air Circulation mode.

8.2. Soft Dry Mode Operation
• The unit starts cooling operation until the room temperature reaches the setting temperature set on the Remote Control, and
then Soft Dry operation will start.
• During Soft Dry operation, the Indoor Fan will operate at Lo- speed.
• The operation will be switched on and off for up to 10 minutes “ON”and 6 minutes “OFF”. Once Soft Dry operation is turned
off, it stops for 6 minutes.
• Once the compressor stops, it will not start for 3 minutes during Cooling operation.
• Same as Starting Current Control for Cooling Mode operation.
• Same as Anti-Freezing Control for Cooling Mode operation. (For Soft Dry region, 6 minutes waiting is valid during compressor
stops.)
• Same as Compressor Reverse Rotation Protection Control for Cooling Mode Operation. (For Soft Dry region, 6 minutes waiting
is valid during compressor stops.)
When Automatic Fan Speed is selected at Remote Control during Soft Dry operation.
• Fan speed off and on at Lo- speed.
• Deodorizing Control.
