Information on drinking water filter
According to DIN 1988-2, a drinking water filter must
be installed in systems with metal pipework. We also
recommend the installation of a drinking water filter
when using plastic pipes, according to DIN 1988, to
prevent contaminants entering the DHW system.
Safety valve
Protect the DHW cylinder with a safety valve against
unduly high pressure.
Recommendation: Install the safety valve higher than
the top edge of the cylinder. This protects the safety
valve against contamination, scaling and high temper-
atures. It also means that the DHW cylinder does not
need to be drained when working on the safety valve.
Connecting the solar circuit
Connect the solar circuit on site.
Connecting a cooling circuit if required
For area cooling systems (e.g. underfloor heating cir-
cuit, chilled ceiling), a contact humidistat (accessory) is
required.
