Flushing the pump :
Cleaning the suction
base and feed impeller :

is bypassed.
1. Push the float switch

onto the float switch lock

with the
cable downward.
2. Stand the pump on a firm surface
– or –
use a rope attached through the bore hole in the carrying
handle

to immerse the pump in a well or shaft.
3. Plug the power cable

into a mains socket.
The residual water height is only reached during manual opera-
tion since the float switch turns off the pump during automatic
operation before this water level is reached.

After having pumped chlorinated swimming pool water or other liq-
uids leaving residues, the pump should be rinsed with clear water.
