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;
• Any protective caps (if any) must be removed prior to installation;
• The pipes and inside of the device 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;
Common procedures (threaded and flanged devices):
• Consider the clearance requirements to replace the filter element;
• 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 filter is installed near other devices or as part of an assembly, compatibility between the filter and these
devices must be evaluated beforehand;
• Provide a protection against impacts or accidental contacts if the device is accessible to unqualified personnel.
3.2 - INSTALLATION (see example in 3.4)
Threaded devices:
• Assemble the device by screwing it, with the due seals, onto the plant with pipes and/or fittings whose threads are
consistent with the connection being attached.
• The arrow, shown on the body (3) of the device, needs to be pointing towards the application;
Flanged devices:
• Assemble the device by flanging it, with the due seals, onto the plant with pipes whose flanges are consistent with the
connection being attached. The gaskets must be free from defects and must be centred between the flanges;
