for use restrictions.
This softener is used to protect the water
pipes and hot water heater against lime-
scale deposits.
Partly softened water protects appliances
and fittings and reduces consumption of de-
tergents and cleaning agents.
3.2 Test marks
The units conform to the technical regula-
tions for drinking water installations in ac-
cordance with DIN 1988. They are tested by
the DVGW (Deutsche Vereinigung des Gas-
und Wasserfaches e.V., i.e. the technical-
scientific association for the gas and water
industries) in accordance with the require-
ments of DIN EN 14743 and DIN 19636-100
for softeners (cation exchangers) in drinking
water installations and are entitled to bear
the DIN-DVGW mark (see Fig. 3).
3.3 Materials used
The materials used are resistant to the
physical, chemical and corrosive loads to be
expected in the drinking water and fulfil the
requirements specified in the DIN EN 14743
and DIN 19636-100 standards (“Softeners
(cation exchangers) in drinking water instal-
lations”). All materials are hygienically and
physiologically safe. Plastics fulfil the official
guideline of the German Federal Environ-
mental Agency. Metallic materials fulfil the
requirements of the DIN 50930-6 standard
(Impact on the drinking water quality).
Limescale deposits inhibit water
flow and can therefore result in in-
creased energy consumption.
