4.3 To change filters
Fig. 3 Remove filter
The filters cannot be cleaned and must be changed as
necessary. This is normally done 1–2 times per year de-
pending on the air pollution at the installation site.
It is very important to change filters regularly for perform-
ance and energy efficiency of the unit.
Each filter has a label with an part number for identifica-
tion. Provide this number when ordering new filters.
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 4.2.
3. Pull out the filters towards you. Some force may be needed.
4. Insert the new filters. Make sure that the correct filter types are inserted.
5. Close and lock the front hatch and connect the unit to mains.
6. Reset the filter time. See chapter 4.3.1.
