Air quality sensor

Clean the air quality sensor every 2 months for optimal functioning of the appliance. Clean it more frequently if you use the appliance in a dusty

environment.

Note:When the humidity level in the room is very high, it is possible that condensation develops on the air quality sensor. As a result, the AIR QUALITY light on the control panel and the air quality light ring may indicate that the air quality is bad even though the air quality is good. In this case you have to clean the air quality sensor or use one of the manual speed settings.

1Clean the air quality sensor inlet and the air quality sensor outlet with a soft brush.

2Remove the air quality sensor cover.
