13. Cartridge capacity table
Use the values in the table for precise monitoring of cartridge capacity rather than the consumption value on the
electronic water meter on the AQA therm HES. The capacity of the HRC cartridges depends on the overall hard-
ness of the water to be treated, and the capacity of the SRC cartridges depends on the conductivity of the water to
be treated. The overall water hardness can also be used as a benchmark, but this only applies to untreated water
and not to previously (partially) softened water. ln this case, the reference value must also be conductivity or, as a
guideline, the overall hardness of the original untreated water (i.e. prior to softening).
