GB
The valid standards and regulations have to be complied with. The cold water connection has
to comply with DIN 1988 / DIN EN 1717 and DIN 4753, Part 1.
In areas with a water hardness of over 20° dH we recommend the use of softening units or
the installation of flush taps in combination with fresh-water storage tanks in order to
facilitate the cleaning of the domestic hot water heat exchanger.

According to technical rules, an appropriate electrical separation of the conductive
connection between the different materials has to be provided for mixed installations.
When installing fast-closing shut-off and water-tapping valves (solenoid valves, ball
valves, single-lever mixers), it might come to short-term pressure shocks in drinking
water installations becoming noticable in the form of disturbing noises and eventually
leading to wear and break of pipes and storage tanks. When using such components,
appropriate water hammer dampers are to be provided. We assume no liability for
damages caused by pressure shocks and water hammers.
