Important notes

The unit must be installed as de-
scribed in the installation instructions
and in compliance with AVB Wasser
V, §12.2 (general requirements for the
supply of water in Germany). It must
Hinweis
be installed by a water utility company
or by an installation company registered in the water
utility company's index of installers.
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 components
High ambient temperatures, e.g. near
a heating unit
Drainage system for regeneration
water incorrectly designed
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.
Using treated drinking water with plants and
aquatic animals
Each species of plant and aquatic animal requires
water that contains a special combination of sub-
stances. Users of the unit should therefore consult
standard literature and check that they can use
retreated drinking water for watering plants or for
filling ornamental lakes, aquariums or fishponds.
The control unit in your product contains a long-
lasting battery.
Do not dispose of single-use or rechargeable
batteries in household waste.
You must bring batteries to a designated collection
point or send them to BWT (free of charge). Used
batteries contain valuable raw materials that can
be recycled.
BWT recommendations
Contact your installer

ing instructions
