• 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, allow the weight of the manifold to
bear only on the connections (threaded or flanged) 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 (11), fully unscrew and remove the central screw (12). Use the designated cable terminals
(see figures below). NOTE: Connector wiring (1) needs to be carried out taking care to ensure the product's IP65 degree
of protection;
• Wire the connector (1) with 3x0.75mm² cable for external Ø 6.2 to 8.1 mm. The cable must be in double sheath, suitable for
outdoor use, with a minimum voltage of 500V and a temperature of at least 120°C;
• Connect terminals 1 and 2 to the power supply and the earth cable to terminal . IMPORTANT: respect the polarity with
12 and 24 Vdc power supplies:
• Secure the connector (11) to the coil (2) by tightening (recommended tightening torque 0.4 N.m ± 10%) the centre screw (12);
• The valve needs to be earthed either through the pipe or through other means (e.g. cable jumpers).
