disassembly as well as the replacement of parts must only be done by the manufacturer or a by an authorized
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.

ELIMINATION
1. Please use a device complying with GS (German
technical supervisory authority) to check for the
presence of voltage (safety information to be
observed!). Please verify the correct position of
the plug.
2. Separate the pump from the electrical mains,
allow the system to cool down, eliminate cause.
3. Please contact the customer service department.
4. Eliminate blocking of pump wheel.

2. Remove possible congestion.
3. Start pump several times so that the entire air will
be driven out.
4. Make sure that the minimum suction level is not
fallen short of; if necessary, adjust floating switch
properly or make sure that it can move freely; in
the case of a defective floating switch, please
contact customer service.
5. Eliminate blocking of the check valve (non-return
valve) or replace, if damaged.
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. Remove possible congestion.
3. Pump may not be suitable for this liquid. If
feasible, the liquid should be thinned.
4. Make sure that the temperature of the liquid being
pumped does not exceed the max. admissible
value.
5. Eliminate causes of dry-running.
1. Remove solids.
2. Refer to section 3.3.
3. Refer to section 3.4.
4. Make sure that mains voltage matches that
indicated on the type plate.
5. Please contact the customer service department.
