Maintenance
3.3 Maintenance instructions
3.3.1 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.
The filters are taken out according to below procedure:
1 Release the filter frame by pulling the filter support
bars.
2 Tilt the support bars to the back.
3 It is now possible to fold the filter and frame back-
wards. This is especially important if there is lack of
space in front of the unit and the sliding door kit is
used.
The filter can now be taken out of the unit.
4 Insert the new filter and fasten it against the inlet seal
with the filter support bars.
Make sure the filter is fitted tight all around the frame.
