6.3 Inspection
According to DIN EN 806-5, the owner/user must inspect the filters every 2 months.
To conduct an inspection, proceed as follows:
1. Check the installation for leaks.
2. Open several water withdrawal points (generate max. flow).
3. Read off the inlet and outlet pressure at the pressure gauges.
4. Calculate the differential pressure: inlet pressure (upper pressure gauge) outlet
pressure (lower pressure gauge) = differential pressure (max. 0.8 bar).
5. Replace the filter elements if the differential pressure is > 0.8 bar.
6. If the differential pressure of the device cannot be reduced by replacing the filter
elements, there is a malfunction.
6.4 Maintenance
WARNING: If the intervals for inspection and replacement are not observed, the filter
elements will become excessively polluted.
● Health risk due to contamination of the drinking water.
► Observe the intervals for inspection and replacement of the filter elements.
Some regular work is necessary in order to ensure the proper functioning of the product in
the long term. For this purpose, DIN EN 806-5 recommends a semi-annual and an annual
maintenance.
The filter elements must be replaced every 6 months for hygiene reasons, in line with DIN
EN 806-5. We recommend replacing the O-ring of the cover every 2 years.
