• 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.
