• Cut out power prior to proceeding with wiring;
• According to the plant geometry, check the risk of explosive mixture arising inside the piping;
• If the solenoid valve is installed near other devices or as part of an assembly, compatibility between the solenoid
valve and this other device must be evaluated beforehand;
• Avoid installing the solenoid valve near surfaces that could be damaged by the coil temperature. ATTENTION:
the surface temperature could cause contact burns. If it is installed in a domestic environment, it must not be
accessible to unqualified personnel;
• The solenoid valve is suitable for installation in places at low risk of mechanical impact. Provide a protection against
impacts or accidental contacts if the solenoid valve is accessible to unqualified personnel.
3.2 - INSTALLATION (see example in 3.4)
• Assemble the device by flanging it, with suitable seals, onto the plant with pipes whose flanges are consistent with the
connection being attached. The gaskets must be free from defects and must be centred between the flanges;
• If, after installing the gaskets, there is still too much space in between, do not try to reduce said gap by excessively tightening
the bolts of the device;
• The arrow, shown on the body (16) 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 the tightening stage;
• When tightening, be careful not to "pinch" or damage the gasket;
• Tighten the nuts or bolts gradually, in a "cross" pattern (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);
• Tighten each nut and bolt again clockwise at least once, until the maximum torque has been achieved uniformly;
• The device must be installed with the horizontal pipe and actuator facing upwards (see figures below);
• 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 resting
only on the connections (threaded or flanged) of the individual devices;
• In any case, following installation, check the tightness of the plant;
• ATTENTION: The valve is provided with a 3m long power supply cable (30). This cable CANNOT be replaced with a
different one. In the event of damage, the part (coil) must be disposed of and replaced with an identical new one; Any repair
(if possible) can only be carried out by the manufacturer;
