8.1 Maintenance Work
Mineral deposits precipitate and crystallize very differently in dif-
ferent types of water, even when two types have the same con-
ductivity and hardness levels (the various constituents in the
water interact differently).
Instructions on maintenance and cleaning intervals, or on elec-
trode service life, are based entirely on empirical data.
In most cases, the conductivity levels given in Section 1.1
"Directions for Use" of these instructions can be considered nor-
mal. Individual parameter setting of the control may be neces-
sary.
In extreme cases, water pretreatment may be necessary (soft-
ening by dilution to approx. 4 - 8 °dH; decarbonization/partial
desalination to achieve target reductions in carbonate hard-
ness). HygroMatik would be pleased to refer you to companies
specializing in water treatment systems.
