10.2 Starting the Pump
(1) Make sure that an unhindered water flow is possible
and not blocked, e.g. by closed valves.
(2) Switch on the PV generator disconnect switch.
(3) Toggle the power switch on the controller to ON.
A solar-direct pump will now start when sufficient irra-
diation levels are reached and neither the well probe,
remote switch or a PumpScanner setting prevent the
controller from starting the pump.
