FUNCTIONAL DESCRIPTION
The unfiltered water flows through the built-in rotary flange into the domestic water station. The water
flows through the fine filter from the outside inwards. The filtered dirt is retained by the mesh of the fine
filter screen. The retained dirt can be seen from the outside through the transparent filter bowl. As long as
the cover of the filter bell is closed, it serves as UV protection. The filtered water flows on into the pressure
reducer. The downstream pressure set can be read off at the manometer. The filtered water then leaves
the domestic water station through the built-in rotary flange.
