Examining the filter elements
Examination of the thickness of the ceramic wall must be done with the measuring gauge provided. As
soon as the gauge can be pushed over the ceramic, it means it has reached its minimum thickness,
and the filter element must be replaced. In addition, elements showing signs of cracks must also be
immediately replaced.
