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;
• The safety regulations on handling loads in force in the country of installation must be complied with. If the device to
be installed exceeds the weight allowed, suitable mechanical equipment and adequate slings must be used. Necessary
precautions must be taken during the handling phases so as not to damage/ruin the external surface of the device.
• 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 main voltage matches the supply voltage indicated
on the product label;
• Cut out power prior to proceeding with wiring;
• According to the plant geometry, check the risk of 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.
