Ozone purifier replacement.
An indicator light is located on the front of the ozonator (optional). To verify that the ozonator is working properly, check to ensure that the indicator light is burning when the filter pump has been running for a while after being activated automatically.
IMPORTANT: The indicator light does not burn if a jet button has been operated manually. The light will remain off for 30 minutes thereafter.
NOTE: If the indicator light does not turn on during automatic filter pump operation, contact your authorised Villeroy & Boch specialist dealer, who will gladly help you.
