2.2 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.
Press "SWING" to engage continous louver motion.
Horizontal and Vertical louver can be set respectively.

2.3 HINTS FOR ECONOMICAL OPERATION

Adjust the temperature to achieve moderate comfort levels. Excessively low or high temperatures
waste energy.
Improve performance by keeping windows and doors closed.
Limit energy usage [run time] by using the TIMER function.
Do not block air inlets or outlets. Poor performance, increased running costs and reduced product life
will result.
Inspect the air filters periodically, and clean them when needed.
Disconnect the power source if unit will not be used for a long period.

NOTE
Horizontal Louver Swing
Vertical Louver Swing
Do not attempt to adjust the louver by hand.
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.
