Common procedures (threaded and flanged devices):
• The device can also be installed vertically without prejudicing correct operation. It cannot be put in
upside down (with the coil (4) 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 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;
• Wiring cannot have cables connected directly to the coil. ALWAYS and ONLY use the connector/electronic board
recommended by the manufacturer;
• Wire the terminal board (32) with a cable 3x1 mm²,
outside Ø between 8.3 and 9.5 mm using the relative
terminals for cables, as shown in the general figure on
the side. The cable to use must have double sheathing,
be suitable for use outdoors, with minimum voltage of
500V, and minimum temperature of 105°C;
To wire the solenoid valve (see the images below):
a. Loosen the 4 fastening screws (1);
b. Remove the cover (2) and loosen the cable gland (3);
c. Pass the cable through the cable gland (3), leaving a suitable length at the end to facilitate wiring to the terminal
board without tensioning or forcing;
d. Secure the cables (duly crimped) to the terminal board (32), connecting terminals 1 and 2 to the power supply and
the earthing cable to the terminal . IMPORTANT: respect the polarity with 24 Vdc power supply;
e. Use a 22mm commercial spanner to secure the cable gland (3) , ensuring the product has a protection rating of IP65;
f. Secure the cover (2) with the 4 fastening screws (1). Make sure to place the rubber sealing gasket (34) correctly in
order to ensure product rating of IP65;
• The valve needs to be earthed either through the pipe or through other means (ex. cable jumpers).
