Flushing and filling the solar circuit (upper connections)
The fill and drain valves required for flushing and filling have been integrated into the
separation station. Make sure that dirt particles that may be present in the system are
not flushed into the heat exchanger and into the expansion tank. To do so, it may be
necessary to disconnect the expansion tank during flushing and filling and to use only
flushing and filling stations that are equipped with suitable microfilters.
The solar circuit is flushed in the normal direction of flow. This is why you should make
sure that the solar circuit pump is not on.
