2.3 HOW IT WORKS
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.]
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 Mode
DRY Mode
Basic Operation Modes
：
AUTO / COOL / DRY / HEAT / FAN
At start-up, a time delay of 3 to 4 minutes protects the compressor.
Compressor Delay
To avoid uncomfortable drafts in heating mode, the indoor unit is preheated before the fan starts. This delay should only last a few
minutes.
Cold Draft Prevention
The unit will automatically restart after a power interruption. Previous user settings are all recovered.
Auto Restart*
When refrigerant leakage is detected, the unit will display “EC” code or flash LEDs.

Louver angle is memorised and will return to the position last selected by the user.
Louver Memory*
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.
Adjusting Air Flow Direction
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.
NOTE
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.
Upward (Cooling)
Horizontal Louver Swing
Ice develops on the outdoor unit in heating mode. To defrost this ice, the indoor fan stops for a few minutes before heating continues.
Auto Defrost
Press “SWING” to engage continous horizontal louver
motion.
Downwards (Heating)
For vertical louver, move the levers left or right to guide
the air in desired direction.
Adjust Vertical Louver

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.
