Separate power supply to the impressed current anode
At the factory, the appliance is fitted with rechargeable batteries that ensure the power supply to the impressed
current anode in the case of a power failure. If regular interruptions to the power supply are not anticipated,
the rechargeable batteries will require no maintenance.
Every three years, a qualified contractor must replace the batteries for the impressed current anode in the
following cases:
-
The impressed current anode is not separately connected to a continuous power supply and a switching
contact regularly interrupts the power supply to the appliance.
-
The security of supply is inadequate.
