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;
• Pull the reset knob (17) slightly and wait a few seconds for the pressure upstream and downstream of the valve to stabilise;
• After balancing the pressures, pull the reset knob (17) until it connects.
NOTE: the green band (15), when visible, indicates that the valve obturator is open.

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 pressurized the system, check the seal and operation of the solenoid valve, electrically
powering / disconnecting the connector ONLY IF connected to the coil.
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
• use a suitable calibration tool to ensure the bolts are tightened as indicated in 3.2;
• check tightness of the flanged/threaded connections on the system;
• check 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
On completion of the operations described below, repeat the procedure indicated in paragraph 5.
If the coil and/or connector need to be replaced (see fig. 1 to 3):
• Before performing any operation, make sure that the device is not electrically powered;
NOTE: if the coil (4) needs to be changed following an electrical failure, we recommend changing the connector (3) as well.
The coil and/or connector replacement operations need to be carried out taking care to ensure the product's IP65 rating.
