INFORMATION FOR THE END USER

Proper operation of the protection system is shown by a continuous green

L.E.D, indicating that the circuits terminals are being supplied with electricity.

In the event of failure, a red L.E.D. indicates that there is a short-circuit

between the electrode and the cylinder tank, that one of the leads (tank or

electrode) is disconnected or that there is no water in the cylinder.

Your appliance is thus properly protected when the green L.E.D. is

illuminated and the red L.E.D. is off. Should this not be the case, please

contact your installer.
