• Tighten them, first by 30%, then by 60%, and finally 100% of the maximum torque (see the table below according to
EN 13611);
Diameter DN 50 DN 65 DN 80 DN 100 DN 125 DN 150 > DN 150
Max. torque (N.m) 50 50 50 80 160 160 160
• Tighten each nut and bolt again clockwise at least once, until the maximum torque has been achieved uniformly;
• The device can also be installed vertically without prejudicing correct operation;
• 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 supports or correctly sized
supports, to properly hold and secure the assembly. Never, for any reason whatsoever, leave the weight of the ramp only on
the connections (threaded or flanged) of the individual devices;
• In any case, following installation, check the tightness of the plant;
