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;
• 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;
