8. SECURITY TIPS
l Obey absolutely valid regulations on the electrical security
l Never run pump dry
l Pumping inammable, as well as all other aggressive liquids is prohibited
l Pay attention to the medium temperature max. 90°C
lNever pull the pump on the electrical cable or pressure hose
lAvoid cross section narrowing
l Pay attention to the given particle size
l During longer unused times, clean the pump, wash it out with clear water, dry and store it at room temperature
l Test wells for enough owing water (dry run danger)
lThe pump is to be secured through a RCD circuit breaker with a release current of 30 mA.
l The electrical connections are always to be carried out by an authorised professional
l Operation can not be performed by children and young people under 16 and people with intellectual disabilities
THE MANUFACTURER EXPLAINS:
l To take over no responsibility in the case of accidents or damages on the basis of carelessness or disregard to the
instructions in this book.
l To reject every responsibility for the damages which originate from the improper use of the pump.
9. SERVICING
Under normal pumping conditions the pump requires no servicing. From an operating period (with clear water)
of approx. 2000 hours the mechanical components should be checked: impeller wheels, chambers, sealing
rings etc. on wear and if necessary be changed. After 3000 pumping hours the oil in the chamber should also
be changed, if necessary (only with oil-dipped engine types!). Please, only ll it up to 80% and check the
sealing rings always for density.
With abrasive materials like sand the servicing duration can become shorter.
The following controls should be carried out regularly:
lIntactness of the electric cable
lThat the connection hoses are not bent or broken
lCleanness of the pump medium
Moreover, the pump should be emptied with risk of frost, be washed out with clear water and stored dry.
