Unit specifications and features

Indoor unit display

MANUAL BUTTON: This button selects the mode in the following order: AUTO, FORCED COOL, OFF.
FORCED COOL MODE: In FORCED COOL mode, the Operation light flashes. The system will then turn to AUTO after it has cooled with a high fan speed for 30 minutes. The remote control will be disabled during this operation.
OFF MODE: When the panel is turned OFF, the unit turns off and the remote control is re-enabled.

Operating temperature
When your air conditioner is used outside of the following temperature ranges, certain safety protection features may activate and cause the unit to disable.
Inverter split type

| COOL mode| HEAT mode| DRY mode
---|---|---|---
Room temperature| 17°C – 32°C| 0°C – 30°C| 10°C – 32°C
Outdoor temperature| -15°C – 50°C| -15°C – 24°C| 0°C – 50°C

When outside temperature is below 0°C we strongly recommend keeping the unit plugged in at all time to ensure smooth ongoing performance.
NOTE: If the air conditioner operates in excess of room relative humidity less than 80%, the surface of the air conditioner may attract condensation. Please sets the vertical air flow louvre to its maximum angle (vertically to the floor), and set HIGH fan mode.
To further optimise the performance of your unit, do the following:

• Keep doors and windows closed.
• Limit energy usage by using TIMER ON and TIMER OFF functions.
• Do not block air inlets or outlets.
• Regularly inspect and clean air filters.

Other features
Default setting
When the air conditioner restarts after a power failure, it will default to the factory settings (AUTO mode, AUTO fan, 24°C (76°F)). This may cause inconsistencies on the remote control and unit panel. Use your remote control to update the status.
Auto-restart
In case of power failure, the system will immediately stop. When power returns, the Operation light on the indoor unit will flash. To restart the unit, press the ON/OFF button on the remote control. If the system has an auto restart function, the unit will restart using the same settings.
Three-minute protection feature
A protection feature prevents the air conditioner from being activated for approximately 3 minutes when it restarts immediately after operation.
Louvre angle memory function
Some models are designed with a louvre angle memory function. When the unit restarts after a power failure, the angle of the horizontal louvres will automatically return to the previous position. The angle of the horizontal louvre should not be set too small as condensation may form and drip into the machine. To reset the louvre, press the manual button, which will reset the horizontal louvre settings.
Refrigerant leak detection system
In the event of a refrigerant leak, the LCD screen will display “EC” and the LED indicator light will flash.

Troubleshooting

SAFETY PRECAUTIONS
If any of the following conditions occurs, turn off your unit immediately!

• The power cord is damaged or abnormally warm
• You smell a burning odour
• The unit emits loud or abnormal sounds
• A power fuse blows or the circuit breaker frequently trips
• Water or other objects fall into or out of the unit

Common issues
The following are not malfunctions and in most situations will not require repairs.

3-minute protection feature that prevents the unit from overloading. The unit cannot be restarted within three minutes of being turned off.
Cooling and heating models: If the Operation light and PRE-DEF (Pre-heating/ Defrost) indicators are lit up, the outdoor temperature is too cold and the unit’s anti-cold wind is activated in order to defrost the unit.
In Cooling-only models: If the “Fan Only” indicator is lit up, the outdoor temperature is too cold and the unit’s anti-freeze protection is activated in order to defrost the unit.
The unit changes from COOL/HEAT mode to FAN mode| The unit may change its setting to prevent frost from forming on the unit. Once the temperature increases, the unit will start operating in the previously selected mode again.
The set temperature has been reached, at which point the unit turns off the compressor. The unit will continue operating when the temperature fluctuates again.
The indoor unit emits white mist| In humid regions, a large temperature difference between the room’s air and the conditioned air can cause white mist.
Both the indoor and outdoor units emit white mist| When the unit restarts in HEAT mode after defrosting, white mist may be emitted due to moisture generated from the defrosting process.
The indoor unit makes noises| A rushing air sound may occur when the louvre resets its position.
A squeaking sound is heard when the system is OFF or in COOL mode. The noise is also heard when the drain pump (optional) is in operation.
A squeaking sound may occur after running the unit in HEAT mode due to expansion and contraction of the unit’s plastic parts.
Both the indoor unit and outdoor unit make noises| Low hissing sound during operation: This is normal and is caused by refrigerant gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is defrosting: This noise is normal and is caused by the refrigerant gas stopping or changing direction.
Squeaking sound: Normal expansion and contraction of plastic and metal parts caused by temperature changes during operation can cause squeaking noises.
The outdoor unit makes noises| The unit will make different sounds based on its current operating mode.
---|---
Dust is emitted from either the indoor or outdoor unit| The unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity.
The unit emits a bad odour| The unit may absorb odours from the environment (such as furniture, cooking, cigarettes, etc.) which will be emitted during operations.
The unit’s filters have become mouldy and should be cleaned.
The fan of the outdoor unit does not operate| During operation, the fan speed is controlled to optimise product operation.
