Translation of the Original Operating Instructions
If necessary, it is recommended to clean the intake filter (4) which can be detached from the pump after loosening
the appropriate screws. Subsequently, please use a steel brush to clean the inner and outer surface of the intake
filter. To conclude the cleaning process, please flush the intake filter with clear water and reattach it to the pump.
Cleaning of the hydraulic parts may only be performed by an authorised specialised dealer or customer service.
To avoid any hazard, any further disassembly as well as the replacement of parts must only be done by the
manufacturer or a by an authorised service provider.
Water left in the pump may freeze in case of frost and thus cause considerable damage. Therefore, the pump
must be removed from the liquid being discharged and fully drained when temperatures are below the freezing
point of the liquid. Please store the pump in a dry, frost-protected place.
In the case of malfunction, you should first of all check whether it was caused by an operating error or some other
reason which cannot be attributed to a defect of the device - for instance a power failure.
The list below shows some possible malfunctions of the device, possible causes and tips on their elimination. All
the measures referred to may only be carried out with the pump being separated from the electrical mains. If you
yourself feel unable to eliminate any of these malfunctions, please contact the customer service department or
your point of sales. Any repair beyond the scope specified below must only be performed by qualified staff.
Please bear in mind that all warranty claims will become void in the case of damage caused by inappropriate
repair attempts, and that we decline any liability for any ensuing damage.

height will not exceed the maximum value.
1. Please use a device complying with GS
(German technical supervisory authority)
to check the voltage of the lines of the
connection cord (safety information to be
observed!).
2. Please refer to items 2.1 to 2.5.
