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;
If the device is threaded:
• make sure that the pipe thread is not too long, to prevent damaging the body of the device when screwing it on;
If the device is flanged:
• 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 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;
