Temporary hardness
The local temporary hardness in gpg (grains per gallon) set during installation of the fi lter system.
Note: If necessary, the units of hardness can also be set to international degrees of hardness mg/L
(CaCO
3
mg/l), see Selecting the units of measurement.
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 funnel is completely fi lled with 10 bars.
By-pass proportion in percentage
The by-pass proportion is defi ned as the proportion of decarbonised water in the total amount of
ltrate and is indicated in percent.
Flow symbol
When water is removed via the fi lter system, a graphic snake is shown in the display.
Available remaining capacity of the fi lter cartridge
The remaining capacity of the fi lter cartridge is shown in US gallons or rather in litres.
When water is removed, it counts backwards in 1 US gallons or rather litre 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.
From a remaining capacity of 0 % the negative bars and the change arrows fl ash alternately with
the remaining capacity shown in negative.

If the monthly limit has been reached up to a month before expiry of the set time limit, it is signalled
by the date fi eld fl ashing.
If the monthly limit is 100% reached, it is signalled by alternate fl ashing of the date fi eld and the
change arrows.
If the remaining capacity and the monthly limit are exceeded, the negative remaining capacity and
the date fi eld fl ash alternately with the change arrows.
Date of the fi lter commissioning or last fi lter cartridge change
The date of fi lter commissioning or last fi lter cartridge change is indicated as follows:
