Troubleshooting
The switch button is lit up only dimly or
not lit up at all.
Is the air purifier switched on?
Switch on the air purifier by pressing the
switch button (page 30).
Has the Quiet function been activated?
If you press the switch button once, the air
purifier switches to automatic mode.
Disable the Quiet function by selecting a
different fan speed via the app or on the
remote control (only IDEAL AP40 Pro).
Automatic mode is not working properly.
The air purifier is calibrating the air quality
sensor. This happens when you first
switch it on and after disconnecting it
from the mains.
Wait until the calibration process has been
completed (this may take a few minutes)
The air quality sensor is not detecting the
air quality reliably.
Calibrate the air quality sensor by briefly
disconnecting it from the mains again!
Odours are not being filtered properly.
Is the air purifier continuously exposed to
strong odours?
The filter needs to be changed
(page 35-36) because the activated
carbon filter becomes saturated and
reliable air purification is no longer
guaranteed.
Are the odours being drawn in at all?
Place the air purifier closer to the source
of the odours.
Switch the air purifier manually to a higher
fan speed (page 30).
