Troubleshooting

If the air conditioner operates abnormally, refer to the following chart to save time and unnecessary expenses.

Problem Solution
The air conditioner does not work at all.	Check the power status, then operate the air conditioner again.Switch on the circuit breaker, plug in the power cord, then operate the air conditioner again.Make sure that the isolator is turned on.Check whether the Timed off function is running. Operate the air conditioner again by pressing the Power button.
I cannot change the temperature.	Check whether the Fan or Fast mode is running. In these modes, the air conditioner controls the set temperature automatically, and you cannot change the set temperature.
Cool air does not come out of the air conditioner.	Check whether the set temperature is higher in the Cool mode than the current temperature. Press the Temperature button on the remote control to change the set temperature.Check whether the air filter is blocked with dirt. If the air filter is blocked, the cooling performance may decrease. Remove dirt regularly.Check whether the outdoor unit is covered or installed near obstacles. Remove the coverings and obstacles.Check whether doors or windows are open. This may cause poor cooling performance. Close the doors and windows.Check whether the air conditioner is turned on immediately after the cooling operation stops. In this case, only the fan runs to protect the outdoor unit compressor.Check whether the pipe length is too long. When the pipe length exceeds the maximum pipe length, the cooling performance may decrease.
I cannot change the air flow direction.	Check whether the good'sleep function is running. While this function is running, you cannot control the air flow direction.
I cannot change the fan speed.	When the Auto, Dry, or Fast mode is running or the good'sleep function is running in the Cool mode, the air conditioner controls the fan speed automatically and you cannot change the fan speed.

22 English

Problem Solution
The remote control does not work.	Replace the batteries in the remote control with new ones.Make sure that nothing is blocking the remote control sensor.Check whether there are strong lighting apparatus near the air conditioner. Strong light which comes from fluorescent bulbs or neon signs may interrupt the electric waves.
The Timed on/off function does not work.	Check whether you pressed the SET button on the remote control after setting the time.
The indicator blinks continuously.	Press the Power button to turn off the air conditioner or disconnect the power plug. If the indicator is still blinking, contact the service centre.
Odours permeate in the room during operation.	Check whether the air conditioner is running in a smoky area. Ventilate the room or operate the air conditioner in the Fan mode for 3 to 4 hours.(There are no components used in the air conditioner that emit a strong odour.)Check whether the drains are clean. Clean them regularly.
An error is indicated.	If the indoor unit indicator blinks, contact the nearest service centre. Be sure to pass the error code to the service centre.
Noise is generated.	When refrigerant flow changes, noise may be generated, depending on the status of the air conditioner. This is a normal operation.
Water drops from the pipe connections of the outdoor unit.	Condensation may develop when the ambient temperature changes excessively. This is a normal operation.
