Subsequent the necessary connections that are per-
formed as inline connections are shown. The gray
connections have to be connected on site, whereby
the rest is pre connected already.
The wire diameter for the main electricity and for the
brine resp. the deep well pump wire has to be dimen-
sioned corresponding to the technical data. (See pa-
ge 3 and 4 for brine resp. groundwater systems)
