2 CHECKING THE USAGE
Magnetic relief valve, open when de-energized, for the
monitoring of gas valves for tightness used in conjunc-
tion with a visual discharge unit. For purging excess
or leakage gas.
This function is only guaranteed when used within the
specified limits– see page 6 (9 Technical data). Any
other use is considered as non-compliant.

3 INSTALLATION
CAUTION
Incorrect installation
Please observe the following to ensure that the
magnetic relief valve is not damaged during instal-
lation and operation:
– Sealing material and dirt, e.g. thread cuttings,
must not be allowed to get into the valve
housing.
– A filter must be installed upstream of every
system.
– Dropping the device can cause permanent
damage. In this event, replace the entire device
and associated modules before use.
– Do not clamp the unit in a vice. Only secure the
flange by holding the octagon with a suitable
spanner. Risk of external leakage.
– Solenoid valves with closed position indicator
VAN..S or VAN..G: actuator cannot be rotated.
➔
Install the unit in the pipe free of mechanical stress.
➔ Installation position: black solenoid actu-
ator in the vertical upright position or tilt-
ed up to the horizontal, not upside down.
➔The housing must not be in contact with masonry,
minimum clearance 20mm (0.79").
1 Obey the direction of flow as marked on the hous-
ing.

4 WIRING
WARNING
Risk of injury!
Please observe the following to ensure that no
damage occurs:
– Electric shocks can be fatal! Before working on
possible live components, ensure the unit is
disconnected from the power supply.
– The solenoid actuator heats up during
operation. Surface temperature approx. 85°C
(approx. 185°F).
➔Use temperature-resistant cable (>80°C).

CAUTION
Please observe the following to ensure smooth
operation:
– Route valve and closed position indicator cables
separately through M20 cable glands or use two
separate plugs. Otherwise, there is a risk of
interference between valve voltage and closed
position indicator voltage.
➔To make wiring easier, the connection terminal for
the closed position indicator can be removed.

7 MAINTENANCE
CAUTION
In order to ensure smooth operation, check the
tightness and function of the unit:
– Once per year, twice per year in the case of
biogas; check for internal and external
tightness, see page 4 (5 Tightness test).
– Check electrical installations once a year in line
with local regulations; pay particular attention to
the PEwire, see page 2 (4 Wiring).
➔If the flow rate has dropped, clean the strainer.
➔We recommend replacing the seals, see accesso-
ries, page 6 (8.2 Seal set VA 1–2).
1 Disconnect the system from the electrical power
supply.
2 Shut off the gas supply.
3 Undo connection parts.
