Do not install the appliance in explosive atmospheres except for the specified gas and dust groups and areas (as explained
in section 2.0).
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
To reset the solenoid valve:
• Make sure the valve is NOT electrically powered;
• Close the flow downstream of the solenoid valve in order to balance the pressure between upstream and downstream when
opening;
• Push the reset handgrip (1) and wait a few seconds for the pressure upstream and downstream of the valve to stabilise;
• After balancing the pressures, pull the reset knob (1) until it connects.
• To close maually the solenoid valve (only M16/RMOCJ N.A. versions), push the closing push button (12).
• The red label under the manual reset (1), if visible, shows that the valve is closed.
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 gradually pressurising the plant, check tightness and operation of the solenoid valve by supplying/cutting
off the electricity.
IMPORTANT NOTE: Do not use the connector as a switch to close the solenoid valve.
• Make sure the solenoid valve is closed by electrically connecting it.
5.1 - RECOMMENDED PERIODIC CHECKS
• Check tightness of the flanged/threaded connections on the system;
• Check tightness and operation of the solenoid valve;
