6.4 Filter flushing
Dirt that has settled in the filter is removed by back-flushing the filter. The back-
flushing process can be started manually, either by activating a setting in the
software or by pressing the start button on the control panel.

Figure 6-6: Filter flushing, first filter 1 then filter 2
If set, flushing will start automatically once a certain amount of water has been
filtered. Back-flushing will either last for a preset duration, or a number of litres will
be back-flushed. Filter flushing will only start between the preset start and end times.
Flushing will also start if an external contact (option) for filter flushing is activated.
