Pumping units or system must be installed and repaired by persons authorized by the user, qualified
and instructed in the operating conditions and principles of work safety.
2.1 Summary of important warnings
−
Voltage and frequency must match the pump nameplate
−
It is forbidden to repair the pump while it is in operation or under the pressure of the pumped liquid.
−
Ensure correct direction of motor rotation.
−
Ensure that the drive motor cannot be started by an unauthorised person when repairing the pumping
unit or equipment (switch off the fuses or suitably secure (lock) the main switch).
−
Only persons who are qualified in electrical engineering according to decree may work on the electrical
equipment, including the connection to the mains.
−
All screw connections must be properly tightened and secured against loosening.
−
The submersible pump must not be moved when it is under voltage.
−
Avoid prolonged pumping without water

insulation, etc.).
2.2 Incorrect application
The submersible wastewater pump is not intended for pumping flammable liquids, petroleum
products and for use in areas with a risk of explosion or for industrial application.
