3.2 - INSTALLATION (see examples 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 not have any 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 (6) 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" pattern (as shown in
the figure at the side);
• 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 device can also be installed vertically without affecting correct operation. It cannot be put in upside
down (with the cover (3) 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 expansion;
• If the device needs 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 resting
only on the connections (threaded or flanged) of the individual devices;
• In any case, following installation, check the tightness of the plant;
• The wiring cannot have cables connected directly to the coil. ALWAYS and ONLY use the connector identified by the
manufacturer;
• Before wiring the connector (10), unscrew and remove the central screw (11). Use the designated cable terminals (see
figures below). NOTE: The connector wiring (10) needs to be carried out by ensuring the product's IP65 protection rating;
• Wire the connector (10) with 3x0.75mm² cable for external Ø 6.2 to 8.1 mm. The cable must feature a double sheath,
suitable for outdoor use, with a minimum voltage of 500V and a temperature of at least 90°C;
• Connect terminals 1 and 2 to the power supply and the earth cable to terminal
• Secure the connector (10) to the coil (13) by tightening (recommended tightening torque 0.4 N.m ± 10%) the centre screw
(11);
• The valve needs to be earthed either through the pipe or through other means (ex. cable jumpers).
3.3 - INSTALLATION IN PLACES WHERE THERE IS THE RISK OF EXPLOSION (DIRECTIVE 2014/34/EU)
The solenoid valve is not suitable for use in potentially explosive areas.
