to the appliance.
Note: Make sure that the side with the two projections is pointing
towards you.
To reattach the front panel, insert the bottom hooks into the
bottom of the appliance first (1). Then push the pannel against the
body of the appliance (2).
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 the air quality sensor has some condensation. 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 thought the air quaity is
good. In this case you have to clean the air quality senor or use one of
the manual speed settings.
Clean the air quality sensor intake and the air quality sensor exit
with a soft brush.
