4.3 Low-level pumping
If low-level pumping is to be carried out, the fluid is lowered down to the upper edge of the
spiral housing. Now switch the pump off and turn it by 90° to pump the fluid up to a residual
water level of a few millimeters.
If low-level pumping is to be carried out, the following points are to be observed:
1. Pump the medium according to section 4.1 of this user manual until the spiral housing
becomes visible. (approx. 10-15 cm residual water level).
2. Switch the pump off by removing the mains plug. Secure the pump against accidental
restarting.
Danger from electric shock:
Only carry out work on the pump when the pump is disconnected from the network by
removing the network plug from the power supply. Prevent accidental restart of the
pump by taking appropriate measures.
3. Turn the pump so that the intake openings face downwards.
4. Switch the pump back on by inserting the power plug.
5. If the intake openings get stuck on solids, first turn off the pump and remove the solids
from the intake openings.
6. Pump the liquid until the pump intakes air. Switch the pump off again.
7. Clean the pump with clear water after each use, particularly after using it with muddy
liquid. In addition, let the pump run for about 10 minutes in a basin with clean water.
The pump is to then be completely emptied. Finally let the pump run without pumped
medium. In case of vibrations, eccentric pump running or grinding noises a customer
service must be carried out in the factory.
