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;
• Device pipes and insides must be clear of any foreign bodies;
• 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;
• 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)
• 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;
• If, after installing the gaskets, there is still an excessive space in between, do not try to reduce said gap by excessively
tightening the bolts of the device;
• The arrow, shown on the body (
3
) of the device, needs to be pointing towards the application;
• Insert the relative washers inside the bolts in order to prevent damage to the flanges during tightening;
• When tightening, be careful not to “pinch” or damage the gasket;
