WARNING!
High temperatures can occur in the solar storage tank.
Therefore, sufficient scalding protection must be
included when the hot water system is installed (auto-
matic hot water mixing device).
The ROTEX units can also be optionally fitted with
gravity brea
ks ( 16 50 70) made of plastic to prevent
thermal losses caused by gravity flow.These are suita-
ble for operating temperatures of maximum 95 °C and
fo
r 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 ROTEX
homepage.
