The subsequent application of a non-conductive coating with a thickness of > 0.2mm on the external surface prohibits its use
in environments with potentially explosive atmospheres where group IIC Gases are present. The thickness of the coating must
be < 2mm for group IIB.
For group III it is necessary to take appropriate precautions to prevent the accumulation of electrostatic charges (e.g. cleaning
with an antistatic cloth, etc.).

4.0 - MANUAL RESET (see fig.1 and 2)
To reset the solenoid valve:
• Make sure there is power;
• Close the flow downstream of the solenoid valve in order to balance the pressure between upstream and downstream when opening;
• Loosen completely and remove the protective cover (7);
• Fully press the reset pin (6) and wait a few seconds for the pressure upstream and downstream of the valve to stabilise until it
locks into place*;
• Screw the protective cover (7) back on in its original place. Or seal it in that position.
5.0 - FIRST START-UP
• Before start-up make sure that all of the instructions on the rating plate, including the direction of flow, are
observed;
• After having gradually pressurised the system, check the tightness and operation of the solenoid valve.
IMPORTANT NOTE: Do not use the connector as a switch to close the solenoid valve.
5.1 - RECOMMENDED PERIODIC CHECKS
• Check the tightness of the flanged/threaded connections on the system;
• Check the tightness and operation of the solenoid valve;
• Clean the product regularly to prevent dust from building up;
