• The arrow, shown on the body (
5
) of the device, needs to be pointing towards the application;
• The device can also be installed vertically without affecting correct operation. It cannot be put in upside
down (with the coil (
12
) 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 or correctly sized supports to 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 identified by the manufacturer;
• Before wiring the connector (
1
), unscrew and remove the central screw (
14
). Use the designated cable terminals (see figures
below).
NOTE:
Coil and/or connector wiring (
1
) need to be carried out taking care to ensure the IP65 rating of the product;
• 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 90°C;
• Connect terminals 1 and 2 to the power supply and the earth cable to terminal ;
• Secure the connector (
1
) to the coil (
12
) by tightening (recommended tightening torque 0.4 N.m ± 10%) the centre screw
(
14
);
• The valve needs to be connected to earth either through the pipe or through other means (e.g. cable jumpers).
