The Daikin units can also be optionally fitted with grav-
ity breaks made of plastic to prevent thermal losses
caused by gravity flow. These are suitable for operating
temperatures of maximum 95 °C and for fitting in all
tank-side heat exchanger connections (except heat
exchangers for pressurised solar tank charging).
The customer must install suitable circulation brakes for
components connected to the heat exchanger for pres-
surised solar tank charging.
A selection of diagrams of the most common systems
is shown below. The arrangements shown are only
examples, and are no substitute for careful system
planning. For more diagrams and further information
about the electrical connection please see the Daikin
homepage.
