DANGER
Risk of fatal injury due to electrical currents in accessible
basins!
Do not operate the pump if there are persons in contact with the fluid. In the
event of a fault this may cause death by electric shock! Only activate the pump
when there are no longer any persons in contact with the fluid.
NOTICE
Check the inlet quantity!
The maximum inlet volume flow must be less than the maximum pump delivery
rate. If the inlet quantity is higher, the pump will not be able to pump away the
volume flow. The pump chamber may overflow!
Check the following prior to commissioning:
▪ Has the electrical connection been carried out in accordance with regulations?
▪ Has the connection cable been routed safely?
▪ Can the float switch move freely?
▪ Has the switching level (minimum water level) been checked?
▪ Have the min./max. temperatures of the fluid been adhered to?
▪ Has the max. immersion depth been adhered to?
▪ Are the pressure pipe and pump sump free of deposits?
