Caution
Always REMOVE THE MAINS PLUG before
carrying out any work on the pump!
To do this, unscrew the suction strainer after re-
moving the pump, take the suction cover off
and clean the impeller space. Check the floa-
ting switch and level probes or submersible
pipe and alarm probe regularly for soiling and
clean if necessary.
Never open the pump yourself (always have an
expert do it) since improper handling could da-
mage the pump seal and allow oil to enter the
wastewater.

tral, isolation transformer or residual current-
operated protective circuit; these must comply
with the requirements of local electricity sup-
