4.0 - MANUAL RESET
To reset the solenoid valve:
• Ensure the solenoid valve is NOT powered;
• Close the flow downstream of the solenoid valve in order to balance the pressure between upstream and downstream when
opening.
• Versions without CPI (see fig. 1):
• Loosen completely and remove the protective cover (2);
• Using a size 32 commercial spanner:
• Turn the reset knob (1) slightly clockwise and wait a few seconds for the pressure upstream and downstream of
the valve to stabilise;
• After balancing the pressure, turn the reset knob (1) clockwise to stroke end, until it is coupled;
• Remove the commercial spanner from the knob (1), then tighten the protective cover (2) back into its original position.
Or seal it in that position.
• Versions with CPI (see fig. 2):
• Loosen the fastening screw (16) and remove the protective cover (2);
• Using a size 32 commercial spanner:
• Turn the reset knob (1) slightly clockwise and wait a few seconds for the pressure upstream and downstream of
the valve to stabilise;
• After balancing the pressure, turn the reset knob (1) clockwise to stroke end, until it is coupled;
• Remove the commercial spanner from the knob (1);
• Screw the protective cover (2) back on in its original place and secure it with the screw (16). Or seal the cover in that position.
IMPORTANT NOTE:
• Hold the pin or size 32 commercial spanner tightly during resetting operations;
• After completing the operation, ALWAYS remember to remove the tool used for resetting in order to avoid the valve from
possibly suddenly closing, which could harm people or damage property if the tool accidentally remains inserted in the knob
(1).
