Check valve is operating,
flow only in flow direction.
Check valve is not operating,
flow in both directions.
Ball valve closed, no flow.
The valves and fittings required to flush and fill are integrated in the heat transfer station.
Make sure not to wash dirt particles from the solar loop into the heat exchanger and the expansion tank.
Therefore only use flush and fill stations with fine filters.
The solar loop is flushed opposite to the normal direction of flow.
Make sure that an unintentional start of the solar pump is not possible by de-energizing the pump.
Check valve bypassing
The storage tank loop is filled with potable water by
means of the valves and fittings of the tank. To avoid that
dirt particles are washed into the heat exchanger, close
the ball valves of the station and wash the dirt particles
and scale residues out of the tank.
1. Open the piston valves (B) (C).
2. Fill the storage tank loop using the valves and fittings
of the tank.
3. Vent the storage tank loop by opening and closing
the pressure relief valve (A) installed in the secondary
circuit.
