5.1 Bypass Setting for Filter Systems without and with Measuring and Display Unit
• Identify the local carbonate hardness in German hardness °dH (BRITA nomenclature °KH) using
the enclosed carbonate hardness test.
• Check the bypass setting on the bypass screw
Note: The bypass has been set to Position 1 in the factory, and must be changed to suit the
local carbonate hardness and the application (Chapter 7).

Carbonate Hardness
The units of carbonate hardness can be set as required to German °dH (= display setting °KH),
English (°e = Clark) (= display setting °EH), French (°f) (= display setting °FH), American (grains
per gallon) (= display setting gpg) or international hardness values (mg/l CaCO
mg/L).
If the setting for the type of hardness (= unit) is changed while the fi lter is operating, the values that
were set originally are converted automatically.
Bar chart
Representation of the remaining capacity using bar charts. After installation of a new fi lter system or
after a fi lter change, the symbolised fi lter cartridge is completely fi lled with 10 bars.
Bypass proportion in percentage
The by-pass proportion is defi ned as the proportion of decarbonised water in the total amount of
fi ltrate and is indicated as a percentage.
Flow symbol
When water is removed via the fi lter system, a graphic wave is shown on the display.
Available remaining capacity of the fi lter cartridge
The remaining capacity of the fi lter cartridge is shown in litres or in US gallons, depending on which
has been selected.
When water is removed, it counts backwards in 1 litre or 1 US gallon stages. If the cartridge is
already exhausted, the capacity is indicated as being negative by fl ashing.
With a remaining capacity of 20% the last two bars in the bar chart start to fl ash.
With a remaining capacity of 10% the last bar in the bar chart fl ashes with the two change arrows.
