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 biologically produced
methane.
Disconnect the system from the electrical power
supply.
Shut off the gas supply.
▷
If the flow rate is correct, see page 4 (Tight-
ness test).
▷
If the flow rate has dropped, clean the strainer.

Follow the reverse procedure when reassembling.
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 4 (Tightness test).
▷
Check electrical installations in line with local reg-
ulations; pay particular attention to the PE wire.
Assistance in the event of
malfunction
WARNING
Electric shocks can be fatal! Before working on
possible live components, ensure the unit is dis-
connected from the power supply. Fault-clearance
must only be undertaken by authorized trained
personnel. Unauthorized repairs or incorrect elec-
trical connections can cause the solenoid valve to
become defective. In this case, our warranty will
be rendered void.
?
Fault
! Cause
•
Remedy
?
The solenoid valve does not open, there is
no flow downstream of the solenoid valve.
!
There is no power supply.
•
Have wiring checked by authorized trained per-
sonnel.
!
Guiding elements bent. Incorrect handling when
installing the unit.
