2.3 HOW IT WORKS

Basic Operation Modes：AUTO / COOL / DRY / HEAT / FAN
AUTO Mode
In this setting the system will automatically change modes and fan speed to the set temperature.
[In spring and autumn, closer temperature control may require COOL/HEAT mode changes.]
DRY Mode
In this mode, priority is given to dehumidifying the air. Low fan speed and compressor cycling is used to
achieve this and regulate room temperature.
Auto Defrost
Ice develops on the outdoor unit in heating mode. To defrost this ice, the indoor fan stops for a few minutes
before heating continues.
Compressor Delay
At start-up, a time delay of 3 to 4 minutes protects the compressor.
Cold Draft Prevention
To avoid uncomfortable drafts in heating mode, the indoor unit is preheated before the fan starts. This delay
should only last a few minutes.
Auto Restart*
The unit will automatically restart after a power interruption. Previous user settings are all recovered.
Auto Leak Detection*
When refrigerant leakage is detected, the unit will display "EC" code or flash LEDs.
Louver Memory*
Louver angle is memorised and will return to the position last selected by the user.
Adjusting Air Flow Direction
Press "AIR DIRECTION" on remote controller to
adjust air flow direction. The louver position moves
slightly each time the button is pressed. Adjust the
louver upwards in cooling mode while downwards
in heating mode to achieve best comfort.
Upward (Cooling)
Air Flow Selection Switch
The draft can be selected to come out from both upper and
lower air outlet or from upper air outlet only.
Open the front panel to get to the Air Flow selection switch.

CAUTION
Do not attempt to adjust the horizontal louver by hand.
Be alert to the moving part when adjust vertical louver. Accidental contact with the fan may cause serious injury.
Disconnect from power source before opening the front panel.
GB-5 7 2
Downwards (Heating)
Selection Switch
Press "SWING" to engage continous horizontal
louver motion.
For vertical louver, move the levers left or right
to guide the air in desired direction.

NOTE
Please refer to the REMOTE CONTROLLER
MANUAL for details.
In cooling or dry mode, condensate may form
and drip from unit in high humidity condition if
louver position is in Maximum down.
Do not operater the unit with louver closed or
narrow opening. Restricted air flow reduced
performance and may cause condensate.
