- If a tool, e. g. a chain pipe wrench, is used when the riser pipe is fitted to the pump, the pump must only be gripped by the
pump discharge chamber.
- When connecting plastic pipes, a compression coupling should be used between the pump and the first pipe section.
- Make sure that the well is capable of yielding a minimum quantity of water corresponding to the pump capacity. Do not
start the pump until it is completely submerged in the liquid. Start the pump and do not stop it until the pumped liquid is
completely clean, as otherwise the pump may choke up.
To avoid damages of the mechanical seal and the motor you should never let the pump run dry or pump against
closed valves!
