4.0 - 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, check tightness and operation of the solenoid valve, by powering /
disconnecting it electrically.
4.1 - 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;
• Clean the product regularly to prevent dust from building up;
• It is essential to eliminate the risk of ignition caused by stray currents or any condition of potential difference between the
devices fitted on the system. Periodically check that there is good electrical conduction between the valve body and the
equipotential plant line and between the coil and the equipotential plant line.
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.
4.2 - ADJUSTMENTS (Models XVPF/NC - XVPCF/NC)
• The flow regulation (if present) can be done with the system stopped and the valve NOT electrically powered. It is
recommended to wait for the coil to cool down (if previously powered) and/or, to use suitable thermal protections
for hands;
• To make this adjustment, you need to unscrew the fastening nut (12) and turn the adjustment screw (13). When you are
finished, tighten and secure the fastening nut in its original position.
5.0 - MAINTENANCE
All maintenance operations must be carried out in the absence of an explosive atmosphere.
