When it’s time to change the filters an alarm is shown on
the control panel display. When this occurs do the
following:
1. Stop the unit by disconnecting the mains.
2. Open the front hatch. See chapter 3.2.
3. Remove old filters and insert new ones. Make sure fil-
ters are not mixed up during the replacement process.
Supply and extract air filters may be different.
4. Close and lock the front hatch and connect the unit to
mains.
5. Reset the filter time as described below (chapter
3.3.1). Depending on the condition of the filter, you
might need to change the operation time for the filter.
