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 filter 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 filter system or
after a filter change, the symbolised filter cartridge is completely filled with 10 bars.
Bypass proportion in percentage
The by-pass proportion is defined as the proportion of decarbonised water in the total amount of
filtrate and is indicated as a percentage.
Flow symbol
When water is removed via the filter system, a graphic wave is shown on the display.
Available remaining capacity of the filter cartridge
The remaining capacity of the filter 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 flashing.
With a remaining capacity of 20% the last two bars in the bar chart start to flash.
With a remaining capacity of 10% the last bar in the bar chart flashes with the two change
arrows.
From a remaining capacity of 0% the negative bars and the change arrows flash alternately with
the remaining capacity shown in negative.
