Important notes

NOTE
► The unit must be installed as described
in the installation guide in compliance with
the general requirements for the supply of
water in Germany ["AVB Wasser"] V, section
12.2 by a water supply company or by a par-
ty registered in the water supply company's
index of fitters.
► In keeping with TrinkwV § 16 and § 21
(German drinking water ordinance), notify
residents of the installation of the water
softener, explain how it works and which
regenerative is used.
Microbiological and sensory quality of the (partially) softened water
The quality of the treated water depends greatly on the conditions under which the unit is installed and
operated. The most important factors are listed in the following table.
Inflow water quality
Operating conditions
Salt quality
Installation situation
and
conditions
When determining whether there is a problem with the sensory or microbiological quality of the treated
water, it is important where in the system the quality is measured. For example, if the quality is measured
at the tap, the water quality may be affected by the pipe material or by the presence of a water heater
or hot water storage tank.
Unfavourable conditions
Borderline inflow water quality,
which can become even worse
within the unit
Long stagnation times and
infrequent regeneration
Cheap regenerative salts with high
proportions of insoluble compo-
nents
High ambient temperatures, e.g.
near a heating unit
Drainage system for regeneration
water incorrectly designed
Using treated drinking water with plants and
aquatic animals
Each species of plant and aquatic animal requires
water that contains a special combination of subs-
tances. Users of the unit should therefore consult
the standard literature and check that they can use
retreated drinking water for watering plants or for
filling ornamental lakes, aquariums or fish ponds.
