9 Operation Details
9.1. Fan Mode Operation
• Fan operation only. Fan in operation according to Remote Control or Main Unit (Touch Control Panel) setting.
9.1.1. Manual Setting of Fan Speed
• Basic Fan Speed can be manually adjusted (Lo or Hi) by using the Fan Speed Selection Button/Pad at Remote Control or Main
Unit (Touch Control Panel).
9.2. Cooling Mode Operation
• Cooling in operation according to Remote Control or Main Unit (Touch Control Panel) setting.
9.2.1. Time Delay Safety Control (3 minute)
• When the compressor is stopped by Operation Switch at the Remote Control or Main Unit (Touch Control Panel), it restart after
3 minutes when the Operation Switch at the Remote Control or Main Unit (Touch Control Panel) is turned ON.
• When the setting temperature is reached during cooling operation, the compressor stops and it will not start for 3 minutes.
• Protection of compressor to balance the pressure in the refrigeration cycle for 3 minutes.
9.2.2. 7 minutes Time Saved Control
• 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.
9.2.3. Starting Current Control
• When the compressor and fan motor are simultaneously started, the fan motor will operate 1.6 seconds later.
9.2.4. Freeze Prevention Control
If the temperature of the indoor heat exchanger falls
continuously below 10°C for 3 minutes or more, the
compressor turns off to protect the heat exchanger from
freezing. The fan speed setting remains the same.
Compressor restarts when the heat exchanger temperature
rises to 12°C (Recovery).
*3 minutes waiting of Time Delay Safety Control is valid for
Cooling Operation.
9.2.5. Compressor Reverse Rotation Protection Control
• If the compressor is operating continuously for 5 minutes or longer and the temperature difference between intake air and heat
exchanger is 2.5°C or less for 2 minutes, compressor will stop and restart automatically (Time Delay Safety Control is valid).

9.2.6. Cooling Operation Time Diagram
9.3. Jet mode Operation
• Purpose of this operation is to obtain the setting temperature quickly.
• When the Jet mode is set during Cooling Operation, the set temperature will be automatically decreased 3°C against the
present setting temperature (Lowest limit temperature: 16°C).
• This operation automatically will be running under Super High Fan Speed.
• Sound emitted by the unit will be increased during Jet mode operation due to increased of air volume.
• Jet mode will operate for 15 minutes only, after that it will shift back to previous operation mode.
• Jet mode will stop if:-
− Jet mode button/Pad is pressed again.
− Jet mode operation has run for 15 minutes.
− Stopped by ON/OFF switch.
− Timer OFF activates.
9.4. Random Auto Restart Control
• If there is a power failure, operation will be automatically restarted after 3 to 4 minutes when the power is resumed.
It will start with previous operation mode and airflow direction (Time Delay Safety Control is valid) as the operation was not
stopped by Remote Control or Main Unit (Touch Control Panel).
• Restart time is decided randomly with 5 parameters:-
− Intake air temperature.
− Setting temperature.
− Fan speed.
− Air Swing blade position.
− Indoor heat exchanger temperature.
• Auto Restart Control is not available when Timer is set.
• If Jet mode operation is set during power failure, Jet mode operation will not start automatically along with previous operation
mode after power resume.
• This control can be omitted by open the circuit JX1.

11.4. Window requirements
• Hot sun rays hitting the outside surface of the cabinet will
create considerable heat load. If the outside of the cabinet
is exposed to direct sunlight, consider building an awning to
shade the cabinet while providing ample area for the heated
air to be exhausted from the condenser (both sides) and the
top.
This unit is designed for installation in standard double hung
windows.
NOTE
The unit may also be installed “through the wall“. You should,
however, observe standard carpentry practices and frame the
opening without violating local ordinances.
11.5. Installation procedures
1. Remove the rear cabinet screws and save for later use.
2. Slide the chassis out from the cabinet.
