Check differential pressure on the filters
► Check the differential pressure on the pressure gauge of the filter.
The differential pressure should be 0.6-0.8 bar max. If the differential pressure
exceeds 0.6-0.8 bar, we recommend that you replace the filter element (see
page 48). The filter elements must be replaced in any case every year.

► At the manometer (1), check pressure
settings of the pressure reducer.
The pressure should be set to 8 bar.
► If the pressure is set to a value above or
below 8 bar, turn the thumbscrew (2) to
