FUNCTIONAL DESCRIPTION
The unfiltered water flows through the built-in rotary flange into the backwashing filter. 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 then leaves the backwashing
filter through the built-in rotary flange. The filter contains a silver-plated suction pipe unit located at the
sieve insert of the protective filter for an optimum prophylactic germ protection. If the prophylactic germ
protection shall remain durably, the suction pipe unit has to be replaced after one year by trained personal.
The function of the filter, however, is unlimited.
