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 the inlet and outlet counter-flanges are perfectly coaxial and parallel in order to prevent unnecessary mechanical
stress to the body. Also calculate the space to insert the seal gasket;
• With regard to tightening operations, equip yourself with one or two calibrated torque wrenches or other controlled locking
tools;
• 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 in order 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 mains voltage matches the supply voltage indicated
on the product label;
