Filling the primary solar circuit
CAUTION
The installation must not be rinsed or filled when the solar
collectors are at more than 100°C (intense sunlight).
Heating up off the collectors may cause fluid leakage in
the form of steam, which may result in scalding / burns.
CAUTION
In order to prevent the risk of frost in the installation, use
only heat transporting fluid to drain the circuit. As a heat
transfer medium, use a water-propylene glycol mix with a
maximum of 50 % propylene glycol.
CAUTION
To prevent impurities getting into the expansion vessel, we
recommend separating the expansion vessel from the rest
of the solar installation during the flushing and filling
phases.
n Flushing procedure
With small systems, use propylene glycol containers to
recover fluid under the empty valve discharge pipe.
CAUTION
Do not carry out rinsing in the event of direct solar radiation
(vapor formation) or if there is risk of freezing (risk of
deteriorations).
Gravity brake in operation.
Stream only runs in direction of flow (arrow on the pipe).
When the installation is running, the valves must be set
back to the vertical position.
Check the circulation on the flowmeter.
Anti-thermosiphon valve completely open.
Stream possible in both directions.
To fill, vent and rinse the installation, the valves must be set
at 45°.
Ball valve closed.
Circulation blocked.
