Maintenance
The controller only functions properly when
the supply air entering the device is always
clean. Therefore, check the air filter and trap
installed in the upstream air reducing station
regularly. If necessary, clean or renew the fil
-
ter.
Insufficiently cleaned supply air will cause the
restriction (1) to become blocked.
