3.0 - COMMISSIONING THE DEVICE

3.1 - OPERATIONS PRIOR TO INSTALLATION
• It is necessary to close the gas upstream of the device prior to installation;
• Make sure that the line pressure DOES NOT EXCEED the maximum pressure declared on the product label;
• Protective caps (if any) must be removed prior to installation;
• The pipes and inside of the device must be clear of any foreign bodies;

• IMPORTANT:

• to avoid possible pumping and/or disturbances in the gas flow, a straight pipe section equal to at least 5 DN must be
installed (downstream of the regulator);
• install manual gas closing devices (e.g. ball valves) upstream and downstream of the regulator to protect it from any
pipe leak test;
• do consider that if the regulator is equipped with a relief valve, the latter is suitable for small quantities of gas to be
discharged and CANNOT replace the relief valve installed separately as a specific device;
