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;
• Check that the line pressure
IS WITHIN the P1 range indicated on the label of the product and that IT IS NOT
HIGHER than the maximum value;
• 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).
• IMPORTANT: install manual gas closing devices (e.g. ball valves) upstream and downstream of the regulator to protect
it from any pipe leak test;
• Make sure that the pipe thread is not too long, to prevent damaging the body of the device when screwing it on;
• If the regulator is not fitted with a filter, it is advisable to install an adequate filter upstream;
• With outdoor installation, it is advisable to install a protective roof to prevent rain from oxidising or damaging parts of the
device.
• According to the plant geometry, check the risk of an explosive mixture arising inside the piping;
• If the regulator is installed near other devices or as part of an assembly, compatibility between the regulator and
these devices must be evaluated beforehand;
• Provide a protection against impacts or accidental contacts if the device is accessible to unqualified personnel.
