 When the solenoid actuator is removed, the gas-
filled space in the VG is opened. Therefore, check
for internal tightness once the new actuator has
been installed, see page3 (Tightness test).
 Tightness OK: release the gas supply.
Maintenance
CAUTION
In order to ensure smooth operation: check the
tightness and function of the VG every year, or every
six months if operated with biogas.
 Disconnect the system from the electrical power
supply.
 Shut off the gas supply.
Cleaning the strainer

Checking tightness and function
▷ When the solenoid actuator is removed, the
gas-filled space in the VGis opened. Therefore,
check for tightness once the actuator has been
reinstalled.
▷ In order to determine whether the VG is tight and
closes securely, check the internal and external
tightness, see page3 (Tightness test).
▷ Check electrical installations in line with local reg-
ulations; pay particular attention to the PE wire.
