9.2 Maintenance frame work
Mineral deposits precipitate and crystallize
very differently in different types of water,
even when two types have the same conduc-
tivity and hardness levels (the various constit-
uents in the water interact differently).
Instructions on maintenance and cleaning
intervals, or on electrode service life, are
based entirely on empirical data.
In most cases, the conductivity levels given in
the "Directions for Use" section of this manual
may be considered as typical values. Individ-
ual parameter settings as part of the control
software may be necessary.
Very seldomly, water pretreatment may be
necessary (softening by dilution to approx. 4 -
8 °gH; decarbonization/partial desalination to
achieve target reductions in carbonate hard-
ness).
For any questions with regard to water treat-
ment systems pls. contact your expert dealer.
