Strange odour	Air filter dirty
Noise of running water	Back flow of liquid in the refrigerant circulation
A fine mist comes from the air outlet	This occurs when the air in the room becomes very cold, for example in the COOLING or DEHUMIDIFYING modes.
A strange noise can be heard	This noise is made by the expansion or contraction of the front panel due to variations in temperature and does not indicate a problem.
Insufficient airflow, either hot or cold	Inappropriate temperature setting. Air inlet or outlet of indoor or outdoor unit has been blocked. Air filter is blocked. Fan speed set at minimum. Other sources of heat in the room. No refrigerant.
The appliance does not respond to commands	Remote control is not near enough to indoor unit. Battery in Remote controller may have been exhausted. Obstacles between remote control and signal receiver in indoor unit.
The display is off	Active LED function Power failure
Switch off the air conditioner immediately and cut off the power supply in the event of:	Strange noises during operation. Faulty electronic control board Faulty fuses or switches. Spraying water or objects inside the appliance. Overheated cables. Very strong smells coming from the appliance.
