5.3 Maintenance Instruction
5.3.1 Changing Supply/Extract Air Filter and Pre-Filter
The bag lter cannot be cleaned and must be changed when necessary. New lters can be ordered from
Systemair. Operation time between lter changes depends on the air pollution at the installation site. A
differential pressure switch indicates when it’s time to change the lters. This will trigger an alarm in the
control panel.
When this occurs do the following:
1. Replace the lters with new ones as described below
2. Acknowledge the alarm by pressing the red button on the control panel (pos. 1 gure 6) followed by OK
(pos. 4 gure 6)
3. Choose →Acknowledge by pressing OK
The lters are taken out by releasing the lter locking handle as shown in (Step 1) below after which the
lters can be taken out and replaced (Step 2) below.
