3.0 - COMMISSIONING THE DEVICE

3.1 - OPERATIONS PRIOR TO INSTALLATION

All installation operations must be carried out in the absence of an explosive atmosphere.
• 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 temperature. ATTENTION:
the surface temperature could cause contact burns. If it is installed in a domestic environment, it must not be
accessible to unqualified personnel;
• The solenoid valve is suitable for installation in places at low risk of mechanical impact. Provide a protection against
impacts or accidental contacts if the solenoid valve is accessible to unqualified personnel.
