To switch off the air quality light ring, press the air quality button.
Note: The air quality light ring automatically goes on when the appliance is
switched on.
The appliance automatically starts operating in the auto mode.
,
To switch off the appliance, press and hold the on/off button again until
the power-on light goes out and unplug the appliance.
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, the auto
mode causes the appliance to run at high fan speed. You can solve this by
cleaning the air quality sensor. If condensation develops frequently during
periods of high humidity, we advise you to use one of the manual speed
settings.
Fan speed lights/filter replacement lights
-
The lights on the right-hand side of the control panel have a dual
function: they either indicate the fan speed or they indicate that the
filters should be replaced or cleaned.
-
When lights 1 to 3/4 light up continuously, they indicate the current fan
speed.
-
When light 1 flashes, you have to clean the pre-filter. When lights 2
and/or 3/4 flash, you have to replace these filters. If lights 2 and/or
3/4 flash, the replacement/lock light also flashes (see chapter 'Filter
replacement' for more information).
-
When lights 2, 3/4 and the replacement/lock light are on continuously,
the appliance is locked (see chapter 'Filter replacement lock' for more
information).
