Hydraulic system connection
To avoid heat losses due to gravity flows, the Daikin
devices can be optionally equipped with plastic non-
return valves. These are suitable for maximum operat-
ing temperatures of 95 °C and for installation in all heat
exchanger connections on the storage tank side (except heat
exchangers for pressurised solar system charging).
Suitable non-return valves must be installed in the building for
components connected to the heat exchanger for pressurised
solar system charging.
The system diagram below is an example, and is never
a substitute for careful system planning. Please visit the
Daikin website for more diagrams and further informa-
tion on electrical connection.
