Translation of the Original Operating Instructions
10
If the pump is to be put out of operation for some extended period of time, it should be emptied completely in by
opening the water drain screw (10). Subsequently, please flush the pump with clean water. Then allow the pump
body to dry completely in order to prevent corrosion damage.
Water left in the pump may freeze in case of frost and thus cause considerable damage. 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.
MALFUNCTION
POSSIBLE CAUSE
ELIMINATION
1. The pump is not
discharging any liquid,
the motor is not
running.

2.
3.
4.
No current.
Thermal motor protection feature has triggered.
The capacitor is defective.
The motor shaft is jamming.

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.
Separate the pump from the electrical mains, allow
the system to cool down, eliminate cause.
Please contact the customer service department.
Check the cause; eliminate the reason for the
jamming of the pump.
2. The motor is running,
but the pump is not
discharging any liquid.

3.
The pump housing is not filled with liquid.
Air penetrates into the intake line.
Suction height and/or discharge height too great.

2.
a)
b)
c)
d)
3.
Fill the pump housing with liquid (please refer to
”Putting into operation” section).
Check to make sure that:
the connection points of the intake line are tight;
the inlet opening of the intake line including the
check valve (non-return valve) are immersed into
the liquids being discharged;
the check valve (non-return valve) with the filter is
tight and not jammed;
no siphons (i.e. permanently liquid-filled loops),
kinks, counter-slopes or narrow spots are present
along the intake lines.
Change the arrangement of the installation so that
the suction height and/or discharge height will not
exceed the max. value.
3. The pump stops after a
short time of operation
because the thermal
motor protection
feature has triggered.
1.
2.
3.
4.
The electrical supply does not correspond to the
information given on the type plate.
Pump or intake line is blocked by solids.
Liquid is too viscous.
Temperature of liquid or environment is too high.

3.
4.
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!).
Remove possible congestion.
Pump may not be suitable for this liquid. If feasible,
the liquid should be thinned.
Make sure that the temperature of the liquid being
pumped and the environment do not exceed the
max. admissible values.
4. The pump does not
reach the desired
pressure.
