Optimum performance will be achieved within these operating temperatures.
When the unit operates above or below these conditions for a long time, system
diagnostics may detect a malfunction and the unit will not operate properly.
Room relative humidity - less than 80%. If the air conditioner operates outside this range,
the surface of the air conditioner may attract condensation.

2. OPEATION
2.2 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.
Auto Leak Detection*
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.
[*] Model dependent
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.
Press “SWING” to engage continous louver motion.
Horizontal and Vertical louver can be set respectively.
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 louver by hand.
Horizontal Louver Swing
Vertical 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

GB-6
DISCONNECT from power source BEFORE attempting to clean or service!
Use a soft damp cloth when cleaning the grille, casing and remote control.
Always contact a qualified service personnel to carry out repair or any
non-user serviceable maintenance, such as deep-cleaning, lubricate and
function check of critical component.
CAUTION
3. CARE AND MAINTENANCE
Cleaning the air filter
To maintain the good performance, regularly inspect air filters and clean them if required.
- Remove the screws to open the grille. - Take out the filter.
NOTE:
The air-in side should face up when using vacuum
cleaner.
The air-in side should face down when using water.
- Clean the air filter
Vacuum cleaner or pure water may be used to clean the air filter. If the dust accumulation is too heavy ,
please use soft brush and mild detergent to clean it and dry out in cool place. Re-install the air filter and air
inlet grille in reverse order described above.
Storage Preparation [long idle periods]
1. Clean the air filters
2. In humid or damp climates, operate in Fan only
mode until the unit has dried out.
3. Turn the air conditioner off with the remote and
remove the batteries.
4. Disconnect from the power source.
Re-useAfter Storge
1. Check if anything block the air inlet and outlet.
2. Clean the air filters
3. Check the wires if any damaged or proper
grounded.
4. Reconnect to the power source
5. Wait 24 hours when the ambient temperature is
low.
6. Reinstall the batteries into the remote controller
and turn the unit on.
General Cleaning
Use a soft damp cloth when cleaning the grille, casing and remote controller.
- No chemicals e.g. detergents, solvents, abrasive polish, etc.
- No heat (over 40
°C)
