If your air conditioner fails to function normally, please first check the following items before requesting maintenance:

Problem	Cause	Corrective measure
The air conditioner can’t run.	If you turn off the unit and then immediately turn it on, in order to protect the compressor and avoid system overload, the compressor will delay running for 3 min.	Please wait for a while.
	Wire connection is wrong.	Connect wires according to the wiring diagram.
	Fuse or circuit breaker is broken.	Replace the fuse or switch on the circuit breaker.
	Power failure.	Restart after power is resumed.
	Power plug is loose.	Reinsert the power plug.
	Wired controller has low battery.	Replace the batteries.

If you are experiencing poor cooling or heating performance, check the following:

Cause	Corrective measure
Air inlet and outlet of indoor or outdoor units have been blocked.	Clear the obstacles and keep the room for indoor and outdoor units well ventilated.
Improper temperature setting.	Reset to a proper temperature.
Fan speed is too low.	Reset to a proper fan speed.
Air flow direction is not right.	Change the direction of air louvers.
Doors or windows are open.	Close them.
Exposed under direct sunshine.	Put on curtains or louvers in front of the windows.
Too many heat sources in the room.	Remove unnecessary heat sources.
Filter is blocked or dirty.	Send for a professional to clean the filter.

The following situations are not operation failures:

Phenomenon	Time of occurrence	Cause
Mist comes from the air conditioner.	During operation.	If the unit is running under high humidity, the wet air in the room will be quickly cooled down.
Water full protection	During operation.	When in cooling mode, if the water level is too high, the machine will shut down for protection to prevent water leakage due to full water. The water pump continues to draw water. After the water level dropped, the machine returned to its normal working state. The water full protection frequency is less than or equal to 3 times.
The air conditioner generates some noise. Dust comes from the air conditioner.	System switches to heating mode after defrosting.	Defrosting process will generate some water, which will turn to water vapor.
	The air conditioner is buzzing at the beginning of operation.	Temperature controller will be buzzing when it starts working. The noise will become weak 1min later.
	When the unit is turned on, it purrs.	When the system is just started, the refrigerant is not stable. About 30s later, the purr of the unit becomes low.
	About 20s after the unit first enables the heating mode or there is refrigerant brushing sound when defrosting under heating.	It’s the sound of 4-way valve switching direction. The sound will disappear after the valve changes its direction.
	There is hissing sound when the unit is started or stopped and a slight hissing sound during and after operation.	It’s the sound of gaseous refrigerant that stops flowing and the sound of drainage system.
	There is a sound of crunching during and after operation.	Because of temperature change, front panel and other components may be swelled up and cause abrasion sound.
	There is a hissing sound when the unit is turned on or suddenly stopped during operation or after defrosting.	Because refrigerant suddenly stops flowing or changes the flow direction.
The air conditioner generates some smell.	The unit starts operation after being unused for a long time.	Dust inside the indoor unit comes out together with the air.
	During operation.	The room smell or the smell of cigarette comes out through the indoor unit.
