7 Operation Details
7.1 Fan Mode Operation
•Fan operation only. Fan in operation according to Remote Control or main Unit ( Touch panel) Setting.
7.1.1 Manual Setting of Fan Speed
• Basic Fan Speed can be manually adjusted (Lo, Hi) by using the Fan Speed Selection Button/Pad at Remote Control or
Main Unit (Touch Control Panel).
7.2 Cooling Mode Operation
•Cooling in operation according to Remote Control or Main Unit ( Touch Control Panel) setting.
7.2.1 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 compresor stops and it will not startfor 3 minutes.
• Protection of compressor to balance the pressure in the refrigeration cycle for 3 minutes.
7.2.2 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.
7.2.3 Starting Current Control
• When the compressor and fan motor are simultaneously started, the fan motor will operate 1.6 second later.
7.2.4 Freeze Prevention Control
If the temperature of the indoor heat exchanger falls con-
tinuously below 1°C for 3 minute or more, the compres-
sor turns off to protect the heat exchanger from freezing.
The fan spee setting remains the same.
Compressor restarts when the heat exchanger tempera-
ture rises to 12°C (Recovery).
* 3 Minutes waiting of Time Delay Safety control is
valid for Cooling Operation.
7.2.5 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 - 15°C for 2 minutes, compressor will stop and restart automatically ( Time Delay Safety Control
is valid).

7.3 Jet Mode Operation
7.2.6 Cooling Operation Time Diagram
• This Operation automatically will be running under High Fan speed, even if the LED shown the Low Fan Speed.
• Purpose of this operation is to cool down room temperature at faster speed compare to normal operation.
• When Jet Mode button is pressed, target temperature is shifted -3oC from the previous setting, for remote control setting from 19oC to
16oC, setting temperature shifted only to 16oC, the minimum setting temperature.

• Jet Mode operation will stop with the following condition :
- Jet Mode button is pressed again.
- Jet Mode operation has run for 15 minutes
- Stopped by OFF/ON switch
- Timer OFF activates.
7.4 Random Auto Restart Control
• Restart time is decided randomly with 5 parameters :
- Intake air temperature.
- Setting temperature
- Fan speed
- Indoor heat exchanger temperature.
• 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 (Time Delay Safety Control is Valid). as the operation was not stopped by Remote Control or main Unit (Touch
Control Panel).
• Auto Restart Control is not available when Timer is set.
• If Jet Mode is set during power failure, then after power resume, Jet Mode will not start automatically with previous operation mode.
• The control can be omitted by opening jumper JX1 on Printed Circuit Main Board.

7.5 Fan Speed Control
• Manual Fan Speed Control
Basic fan speed adjusment (2 setting from Low to High) can be carried out by using the Fan Speed Selection button /
Pad at the remote control or Main Unit (Touch Control Panel).
• The side-to-side airflow direction vane can be adjusted manually by hand.
• To Switch off or on the beep sound.
Press the “Operation OFF/ON Pad” at the main unit continously for 10 second or more. repeat the above if you want to
switch ON the “beep” sound. Howevr, if the “Operation OFF/ON Pad” have been pressed, the previous operation mode
will be activated. If you do not require this operation, ou may change it by using the Main unit (Touch control Panel).

Caution : Please read the following before installing the air conditioner. Select the best location for the
most efficient cooling.
The air conditioner should be installed in a dry place where there are no draughts.
Condensation from the air conditioner must be drained to an appropriate location.
Do not install in a location where flammable gas leaks are possiblility.

There should not be any obstacles surrounding the unit.
Prepare the installation hole slightly bigger than cabinet size.
Using in location where the air is salty such as beside the sea or near hot spas, or where sulphurous gas is generated, may lead to a
malfunction. Please consult to your dealer.

Slide the chassis out from the cabinet.
1) PREPARE CHASSIS
2) Place cabinet into opening and secure it by wood screws or nails.
The cabinet should be installed titled slightly lower to the rear for necessary
condensate drainage.(Max. 10mm)
5) Place FRONT GRILLE onto cabinet by a screw.
