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 con-
stituents 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 man-
ual may be considered as typical values. Indi-
vidual 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.
* If the water quality differs, this could result
in a more frequent need for maintenance.
