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 party 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.
Unfavourable conditions
BWT recommendations
Inflow water quality
Borderline inflow water quality,
which can become even worse
within the unit
Contact your installer
Shorter maintenance intervals
Operating conditions
Long stagnation times and infre-
quent regeneration
Observe the notes in the operating
instructions
Salt quality
Cheap regenerative salts with high
proportions of insoluble compo-
nents
Use regenerative in accordance with
DIN EN 973 type A
Installation situation
and conditions
High ambient temperatures, e.g.
near a heating unit
Drainage system for regeneration
water incorrectly designed
For all issues about sensory and microbiological quality of the treated water, there is a difference depending
on the location, from which these are being evaluated. In terms of an evaluation at an extraction point,
the pipe material, water heater or hot water storage tank, among other things, could have a decisive
impact on the water quality.
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.
The control unit in your product contains a long-
lasting battery.
Do not dispose of single-use or rechargeable bat-
teries 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.
