4.0 - MANUAL RESET
To reset the solenoid valve:
• Make sure the power supply is connected;
• Close the flow downstream of the solenoid valve in order to balance the pressure between upstream and downstream when
opening.
• DN 65 - DN 80 - DN 100 - DN 125 - DN 150
without CPI (see fig. 1):
• Loosen completely and remove the protective cover (
13
);
• Loosen the reset pin (
14
) from the fastening screw (
15
);
• Insert the non-threaded part of the reset pin (
14
) in the hole provided on the hex knob (
1
);
• Using the pin (
14
):
• 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 its stroke end, when it is coupled;
• Remove the pin (
14
) from the knob (
1
) and screw it on in its original position. Alternatively to the reset pin (
14
), it is
possible to use a size 32 commercial spanner to turn the reset knob (
1
);
• Screw the protective cover (
13
) back on in its original place. Or seal it in that position.
• DN 200 - DN 250 - DN 300
without CPI (see fig. 2):
• Loosen completely and remove the protective cover (
13
);
• 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 its stroke end, when it is coupled;
• Remove the commercial spanner from the knob (
1
), then tighten the protective cover (
13
) back into its original position.
Or seal it in that position.
• DN 65 - DN 80 - DN 100 - DN 125 - DN 150 - DN 200 - DN 250 - DN 300
with CPI (see fig. 3 and 4):
• Loosen the fastening screw (
23
) and remove the protective cover (
13
);
• 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 its stroke end, when it is coupled;
• Remove the commercial spanner from the knob (
1
);
• Screw the protective cover (
13
) back on in its original place and secure it with the screw (
23
). Or seal the cover in that
position.
