7 MAINTENANCE
In order to ensure smooth operation, check the
tightness and function of the pressure switch every
year, or every six months if operated with biogas.
➔ A function check can be carried out in case of
falling pressure monitoring, e.g. with the PIA.
➔ After carrying out the maintenance work, check
for tightness, see page 3 (6 Tightness test).
