Operation

The appliance does not work normally.

Cause

Burning smell and strange sounds are coming from the appliance.

Solution

  • Turn off the appliance, switch off or disconnect the power supply, and contact a service centre.

Cause

Water leaks from the indoor unit even when the humidity level is low.

Solution

  • Turn off the appliance, switch off or disconnect the power supply, and contact a service centre.

Cause

The power cable is damaged or it is generating excessive heat.

Solution

  • Turn off the appliance, switch off or disconnect the power supply, and contact a service centre.

Cause

A switch, a circuit breaker (safety, ground) or a fuse is not operating properly.

Has the fuse blown or has the circuit breaker been tripped?

Solution

  • Turn off the appliance, switch off or disconnect the power supply, and contact a service centre.

Cause

The appliance generates an error code from its self-diagnosis.

Solution

  • Turn off the appliance, switch off or disconnect the power supply, and contact a service centre.

The fan speed cannot be adjusted.

Cause

The Jet mode or Auto Operation mode is selected.

Solution

  • In some operating modes, you cannot adjust the fan speed. Select an operating mode in which you can adjust the fan speed.

Cause

The airflow generated by the air conditioner may be automatically adjusted during operation.

Solution

  • When the air conditioner reaches the set temperature, it reduces the airflow rate to avoid generating cool airflow when heating, or to minimize energy consumption and indoor humidity change when cooling.

The temperature cannot be adjusted.

Cause

The Fan mode or Jet mode is selected.

Solution

  • In some operating modes, you cannot adjust the temperature. Select an operating mode in which you can adjust the temperature.

The appliance stops during operation.

Cause

The appliance is suddenly turned off.

Solution

  • The Off Timer function may have timed out, which turns the appliance off. Check the timer settings.

Cause

Have you made a mistake in timer operation?

Solution

  • Set the timer correctly.

Cause

A power failure has occurred during operation.

Solution

  • Wait for the power to come back on. If you have the Auto Restart function enabled, your appliance will resume its last operation several minutes after power is restored.

The appliance does not work.

Cause

A fuse blew or the power supply is blocked.

Solution

  • Replace the fuse or check if the circuit breaker has tripped.

Cause

The appliance is unplugged.

Solution

  • Check whether the power cord is plugged into the outlet or the power isolators are switched on.

Cause

A power failure has occurred.

Solution

  • Turn off the appliance when a power failure occurs.

  • When the power is restored, wait 3 minutes, and then turn on the appliance.

Cause

The voltage is too high or too low.

Solution

  • Check if the circuit breaker has tripped.

Cause

The appliance was turned off automatically at a preset time.

Solution

  • Turn the appliance on.

Cause

The battery orientation in the wireless remote control is incorrect.

Solution

  • Make sure that the batteries are inserted correctly in your wireless remote control.

  • If the batteries are placed correctly, but the appliance still does not operate, replace the batteries and try again.

Cause

Are the indoor unit's air inlet or outlet vents obstructed?

Solution

  • Remove the obstacles.

The appliance does not emit cool air.

Cause

Air is not circulating properly.

Solution

  • Make sure that there are no curtains, blinds, or pieces of furniture blocking the front of the appliance.

Cause

The air filter is dirty.

Solution

  • Clean the air filter once every 2 weeks.

  • See “Cleaning the Air Filter” for more information.

Cause

The room temperature is too high.

Solution

  • In summer, cooling the indoor air fully may take some time. In this case, select the Jet mode to cool the indoor air quickly.

Cause

The room may have been very hot when the room air conditioner was first turned on.

Solution

  • Allow time for it to cool down.

Cause

Cold air is escaping from the room.

Solution

  • Make sure that no cold air is escaping through the ventilation points in the room.

Cause

The desired temperature is higher than the current temperature.

Solution

  • Set the desired temperature to a level lower than the current temperature.

Cause

There is a heating source nearby.

Solution

  • Avoid using heat generators like electric ovens or gas burners while the air conditioner is in operation.

Cause

Fan mode is selected.

Solution

  • During Fan mode, air blows from the appliance without cooling or heating the indoor air.

  • Switch the operating mode to a cooling operation.

Cause

Outside temperature is too high.

Solution

  • The cooling effect may not be sufficient.

The appliance does not emit warm air.

Cause

When the Heating mode starts, the vane is almost closed, and no air comes out, even though the outdoor unit is operating.

Solution

  • This is normal. Please wait until the appliance has generated enough warm air to blow through the indoor unit.

Cause

The outdoor unit is in Defrosting mode.

Solution

  • In Heating mode, ice and frost is built up on the coils when the outside temperature falls. The Defrosting mode reduces a layer of frost on the coil, and it should finish in approximately 15 minutes.

Cause

Outside temperature is too low.

Solution

  • The heating effect may not be sufficient.

The air conditioner changes generated airflow during operation.

Cause

When the appliance reaches the desired temperature, the airflow rate reduces in order to avoid generating cool airflow during heating, or to minimize energy consumption and indoor humidity change during cooling.

Solution

  • This symptom is normal.

It seems that condensation is leaking from the air conditioner.

Cause

Condensation occurs when the airflow from the air conditioner cools the warm room air.

Solution

  • This symptom is normal.
