Maintenance
4.3.2 Changing supply/extract air filter
The bag filter cannot be cleaned and must be changed when necessary. New filters can be ordered from Systemair. Op-
eration time between filter changes depends on the air pollution at the installation site. A differential pressure switch
indicates when it’s time to change the filters. This will trigger an alarm in the control panel.
When this occurs do the following:
1. Replace the filters with new ones as described below.
2. Press on the alarm symbol
on the control panel.
3. Choose Filter alarm and press acknowledge.
Open the door as described in chapter 4.3.1. Loosen the knob on the rail that holds the filter (pos 1) and rotate the rail.
Pull out the filters.
