• The arrow, shown on the body (9) 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;
• Tighten the nuts or bolts gradually, in a "cross" order (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);
Diameter
Max. torque (N.m)
• 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 the correct operation. It cannot be put in
upside down (with the reset knob (17) pointing downwards);
• 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 dilation;
• 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 (flanged or threaded) of the individual devices;
• In any case, following installation, check the tightness of the plant;
• Wiring cannot have cables connected directly to the coil. ALWAYS and ONLY use the connector identified by the
manufacturer;
• Before wiring the connector (3), unscrew and remove the central screw (2). Use the proper cable terminals (see figures
below). NOTE: Connector (3) wiring must be do ensuring a product rating of IP65;
• Wire the connector (3) with 3x0.75mm² cable for external Ø 6.2 to 8.1 mm. The cable to be used must be in double sheath,
suitable for outdoor use, with a minimum voltage of 500V and a temperature of at least 60 °C;
• Connect terminals 1 and 2 to the power supply and the earth cable to terminal ;
• Secure the connector (3) to the coil (4), tightening (recommended tightening torque 0.4 N.m ± 10%) the clamping screw (2);
• The valve needs to be connected to earth either through the pipe or through other means (ex. cable jumpers).
