1.0  GENERAL INFORMATION
This manual shows you how to safely install, operate and use the device.
The instructions for use ALWAYS need to be available in the facility where the device is installed.
ATTENTION: installation/wiring/maintenance need to be carried out by qualified staff (as explained
in section 1.3) by using suitable personal protective equipment (PPE).
For any information pertaining to installation/wiring/maintenance or in any case problems that cannot be solved with the
instructions, contact the manufacturer by using the address and phone numbers provided on the last page.
1.1  DESCRIPTION
Normally closed, manual reset solenoid valves for gas, suitable to shut off gas both to signal danger sent by gas detectors
(methane, LPG, carbon monoxide and similar) or safety thermostats, and in the event of a power cut.
For additional safety, this solenoid valve can only be reset with the power supply on and only when the gas detector is not
signalling danger.
IMPORTANT NOTE: The valve will not open by simply powering the coil. You must manually press the reset
mechanism (as indicated in 4.0).
Reference standards: EN 161 - EN 13611.

3.0  COMMISSIONING THE DEVICE
3.1  OPERATIONS PRIOR TO INSTALLATION
•It is necessary to close the gas upstream of the valve prior to installation;
•Make sure that the line pressure DOES NOT EXCEED the maximum pressure declared on the product label;
•Any protective caps (if any) must be removed prior to installation;
•Valve pipes and insides must be clear of any foreign bodies;
• Make sure that the pipe thread is not too long, to prevent damaging the body of the device when screwing it on;
•In accordance with EN 161, a suitable filter must be installed upstream of a gas closing safety device;
•With outdoor installation, it is advisable to provide a protective roof to prevent rain from damaging the electrical parts of
the device;
•Prior to carrying out any electrical wiring operations, make sure that the mains voltage matches the supply voltage indicated
on the product label;
•Cut off power prior to proceeding with wiring;
•According to the plant geometry, check the risk of an explosive mixture arising inside the piping;
•If the solenoid valve is installed near other devices or as part of an assembly, compatibility between the solenoid
valve and this other device must be evaluated beforehand;
• Avoid installing the solenoid valve near surfaces that could be damaged by the coil’s temperature;
•Provide a protection against impacts or accidental contacts if the solenoid valve is accessible to unqualified personnel.
3.2  INSTALLATION (see example in 3.4)
•Assemble the device by screwing it, with the due seals, onto the plant with pipes and/or fittings whose threads are consistent
with the connection being attached;
•Do not use the coil (12) as a lever to help you screw it on, only use the specific tool;

17
IT EN FR ES
•The arrow, shown on the body (5)of the device, needs to be pointing towards the application;
•The device can also be installed vertically without affecting correct operation. It cannot be put in upside
down (with the coil (12) pointing downwards);
•During installation, avoid debris or metal residues from getting into the device;
•To guarantee mechanical tension-free assembly, we recommend using compensating joints, which also
adjust to the pipe’s thermal expansion;
•If the device is to be installed in a ramp, it is the installer’s responsibility to provide suitable or correctly sized supports to hold
and secure the assembly. Never, for any reason whatsoever, leave the weight of the ramp only on the connections (threaded or
flanged) of the individual devices;
•In any case, following installation, check the tightness of the plant;
• Wiring cannot have cables connected directly to the coil. ALWAYS and ONLY use the connector identified by the manufacturer;
•Before wiring the connector (1), unscrew and remove the central screw (14). Use the designated cable terminals (see figures
below). NOTE: Coil and/or connector wiring (1) need to be carried out taking care to ensure the IP65 rating of the product;
•Wire the connector (1) with 3x0.75mm² cable for external Ø 6.2 to 8.1 mm. The cable must be in double sheath, suitable for
outdoor use, with a minimum voltage of 500V and a temperature of at least 90°C;
•Connect terminals 1 and 2 to the power supply and the earth cable to terminal ;
•Secure the connector (1) to the coil (12) by tightening (recommended tightening torque 0.4 N.m ± 10%) the centre screw
(14);
•The valve needs to be connected to earth either through the pipe or through other means (e.g. cable jumpers).

4.0  MANUAL RESET (see fig.1 and 2)
To reset the solenoid valve:
• Make sure there is power;
•Closetheflowdownstreamofthesolenoidvalveinordertobalancethepressurebetweenupstreamanddownstreamwhenopening;
•Loosen completely and remove the protective cover (7);
•Fully press the reset pin (6) and wait a few seconds for the pressure upstream and downstream of the valve to stabilise until it
locks into place*;
•Screw the protective cover (7) back on in its original place. Or seal it in that position.
5.0  FIRST STARTUP
•Before start-up make sure that all of the instructions on the rating plate, including the direction of flow, are
observed;
•After having gradually pressurised the system, check the tightness and operation of the solenoid valve.
IMPORTANT NOTE: Do not use the connector as a switch to close the solenoid valve.
5.1 - RECOMMENDED PERIODIC CHECKS
•Check the tightness of the flanged/threaded connections on the system;
•Check the tightness and operation of the solenoid valve;
It is the responsibility of the final user or installer to define the frequency of these checks based on the severity of the service
conditions.

6.0  MAINTENANCE
No maintenance operations need to be carried out inside the device.
If the coil and/or electronic board/connector need to be replaced:
•Before performing any operation, make sure that the device is not electrically powered;
•Since the coil is also suitable to be permanently powered, coil heating in case of continuous operation is an entirely
normal phenomenon. It is advisable to avoid touching the coil with bare hands after a continuous power supply lasting
longer than 20 minutes. In case of maintenance, wait for the coil to cool down or, if necessary, use suitable protections;
NOTE: if the coil (12) needs to be changed following an electrical failure, we recommend changing the connector (1) as well.
The coil and/or connector replacement operations need to be carried out taking care to ensure the product’s IP65 rating.
6.1 - REPLACING THE CONNECTOR
•Fully unscrew and remove the central screw (14), then remove the connector (1) from the coil (12);
•When you have taken out the existing internal electrical wiring, wire the new connector and secure it to the coil, as shown in 3.2;
6.2 - REPLACING THE COIL
•Fully unscrew and remove the central screw (14), then remove the connector (1) from the coil (12);
•Loosen the screw (13) that locks the coil (12) and take it out from the armature assembly (11 ) along with the gaskets/discs;
•Insert the new coil + seals + discs into the armature assembly (11 ) and secure everything with the screw;

7.0  TRANSPORT, STORAGE AND DISPOSAL
• During transport the material needs to be handled with care, avoiding any impact or vibrations to the device;
• If the product has any surface treatments (e.g. painting, cataphoresis, etc), it must not be damaged during transport;
• The transport and storage temperatures must observe the values provided on the rating plate;
• If the device is not installed immediately after delivery, it must be correctly placed in storage in a dry and clean place;
• In humid facilities, it is necessary to use driers or heating to avoid condensation;
• At the end of its service life, the product is to be disposed of separately from other waste (WEEE directive 2012/19/EU)
and in compliance with the legislation in force in the country where this operation is performed.
