Step Action Illustration
1 Release the three screws from
the front at the bottom of the
unit and remove the front cover.
The unit has a built-in filter alarm timer (every six months as standard). The timer period for
the filter alarm can be changed via the remote control or PC Tool, or it can be reset via the
alarm button
When the timer expires, a filter alarm is triggered. A buzzer will sound and the LED “!” will light
up orange. (If the LED lights up RED, please see Troubleshooting on page 43.)
Press for 5
sec.
Resets the filter alarm when the alarm is triggered.
Resets the filter timer without the timer having expired.
A short beep will sound, indicating that the filter alarm has been reset correctly.
Step Action Illustration
1 Remove the filters and inspect them
after the filter alarm has been triggered.
2 Even if only one filter is clogged, we
recommend replacing both filters to
avoid imbalance in the airflow through
the unit.
NOTE: Replace the filters at least once
a year, regardless of whether they are
clogged or an alarm has been triggered.
3 Make sure that the filters are inserted
the right way. The arrows on the filter
must point in the direction shown here.
4 When the filters have been replaced, the
filter alarm must be reset by pressing
the alarm button for 5 seconds.
A short beep will sound, indicating that
the filter alarm has been reset correctly.
