5.4 Water connection
▶ Mark the cold water lines and the DHW lines accordingly to
avoid confusion (Fig. 10).

▶ Use suitable accessories for the hydraulic connection of
the DHW cylinder.

Risk of frost:
▶ Switch off the DHW cylinder.
▶ Drain the DHW cylinder ( sec. 6.3).

NOTICE: Corrosion damage to the DHW
cylinder's connections!
▶ Provide the water connections with
insulating dielectric unions. This prevents
current (DC current) from flowing between
the metal hydraulic connections and the
resulting corrosion.
NOTICE: Material damage!
▶ Use a filter at the water inlet if the water has
suspended matter.
Recommendation:
▶ Flush the system beforehand as the water
flow could be reduced by contaminants and,
in case of severe contamination, be stopped
completely.
We recommend the installation of a non-return
valve upstream of the cylinder to prevent faults
resulting from sudden pressure fluctuations in
the water supply (Fig. 11, [7]).
DANGER:
▶ Fit a pressure relief to the cold water
connection on the DHW cylinder (Fig. 11).
