Changing filters
The filters cannot be cleaned and must be changed as necessary. This is normally done 1–2 times per year depending
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 and remove the side cover. See chapter 4.2.
3. Pull out the filters towards you. Some force may be needed.
