9 10 Checking correct rotational direction
The submersible pump must be submerged in water before
checking the correct rotational direction. The correct rota-
tion direction for submersible pumps is counter-clockwise,
viewed from the top. It is also labeled with an arrow on the
pump end.
Check the rotational direction as follows:
1.
Connect the pump to the controller and power
supply.
2.
Start the pump and check the delivered flow rate.
3.
Stop the pump, disconnect the power supply and
change two of the three phase leads (e.g. red and
yellow).
4.
Start the pump again and check the delivered flow.
5.
Stop the pump, disconnect the power supply and
compare the flow rates from point 2 and 4. The wir-
ing with the better flow rate has the right rotational
direction.
