Flushing the pump:
Cleaning the suction
base and feed impeller:
The pump remains in constant operation because the float switch
is bypassed.
1. Push the float switch 5onto the float switch lock 3with the
cable downward.
2. Stand the pump on a firm surface
– or –
use a rope attached through the bore hole in the carrying
handle 2to immerse the pump in a well or shaft.
3. Plug the power cable 1into 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.
5. Cleaning
The pumps are virtually maintenance-free.
After having pumped chlorinated swimming pool water or other liq-
uids leaving residues, the pump should be rinsed with clear water.
