WARNING!
To prevent the emission of exhaust gas, before com-
missioning the ROTEX GCU compact, the storage
tank container must be filled up to the overflow mark.
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).
CAUTION!
The ROTEX units can also be optionally fitted with
gravity breaks (
16 50 70 ) made of plastic. They
are suitable for maximum operating temperatures of
95°C. If a heat exchanger is operated at temperatures
greater than 95°C, another gravity brake must be
installed in the building.
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 see the ROTEX home-
page.
