• Tighten the nuts or bolts gradually, in a "cross" pattern (see the example below);
• Tighten them, first by 30%, then by 60% and finally 100% of the maximum torque (see the table below according to EN
13611);
• Tighten each nut and bolt again clockwise at least once, until the maximum torque has been achieved uniformly;
• The filter can be installed in any position as long as the arrow, indicated on the body (3) of the appliance, faces the application;
• During installation, avoid debris or metal residues from getting into the device;
• To guarantee mechanical tension-free assembly, we recommend using compensating joints, which also
adjust to the pipe's thermal expansion;
• If the device is to be installed in a ramp, it is the installer's responsibility to provide suitable or correctly sized supports
to hold and secure the assembly. Never, for any reason whatsoever, leave the weight of the ramp resting only on the
connections (threaded or flanged) of the individual devices;
• In any case, following installation, check the tightness of the plant;
