Translation of the Original Operating Instructions
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 elimi-
nate 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 per-
formed 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 de-
cline 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 ob-
served!). Please verify the correct position of the
plug.
2.
Separate the pump from the electrical mains, allow
the system to cool down, eliminate cause.

1.
Fill the pump housing with liquid (please refer to
"Putting into operation" section).
2.
Check to make sure that:
a)
the connection points of the intake line are tight;
b)
the inlet opening of the intake line including the
check valve (non-return valve) are immersed into
the liquids being discharged;
c)
the check valve (non-return valve) with the filter is
tight and not jammed;
d)
no siphons (i.e. permanently liquid-filled loops),
kinks, counter-slopes or narrow spots are present
along the intake lines.
3.
Change the arrangement of the installation so that
the suction height and/or discharge height will not
exceed the max. value.
