4.0 - MANUAL RESET (see fig.1, 2 and 3)
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 and remove the protective cover (9);
• Fully press the reset pin (10) 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 (9) 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, reset the solenoid valve, as indicated in 4.0;
• Check the tightness, the operation and the closing of the solenoid valve, electrically disconnecting the connector ONLY IF
connected to the coil. IMPORTANT NOTE: Do not use the connector as a switch to close the solenoid valve.
5.1 - RECOMMENDED PERIODIC CHECKS
• Use a suitable calibration tool to ensure the bolts are tightened as indicated in 3.2;
• Check the tightness of the flanged/threaded connections on the system;
• Check the tightness and operation of the solenoid valve;
It is the responsibility of the final user or installer to define the frequency of these checks based on the severity of the service conditions.
6.0 - MAINTENANCE
No maintenance operations need to be carried out inside the device.
On completion of the operations described below, repeat the procedure indicated in paragraph 5.
