10. Warranty
The present device was manufactured and inspected according to the latest methods. The seller warrants for
faultless material and workmanship in accordance with the legal regulations of the country in which the device
was purchased. The warranty period begins with the day of the purchase and is subject to the provisions below:
Within the period of warranty, all defects which are to be attributable to defective materials or manufacturing will
be eliminated free of charge. Any complaints are to be reported immediately upon their detection.
The warranty claim becomes void in the case of interventions undertaken by the purchaser or by third parties.
Damage resulting from improper handling or operation, incorrect setting-up or storage, inappropriate connection
or installation or Acts of God or other external influences are excluded from warranty.
Parts being subject to wear and tear, such as the pump wheel (impeller) and mechanical shaft seals are excluded
from warranty.
All parts were manufactured using maximum care and high-quality materials and are designed for a long lifecycle.
It should be understood, however, that the wear and tear depends on the kind of use, the intensity of use and the
internals of maintenance. Complying with the installation and maintenance information contained in the present
operating instructions will therefore considerably contribute to a long lifecycle of these wearing parts.
In case of complaints, we reserve the option of repairing or replacing the defective parts or replace the entire
device. Replaced parts will pass into our property.
Claims for liquidated damages are excluded unless they are caused by willful acts or negligence on the side of
the manufacturer.
The warranty does not provide for any claims beyond those referred to above. The warranty claim has to be
evidenced by the purchaser in the form of the submission of the sales receipt. The present warranty commitment
is valid in the country in which the device was purchased.
POSSIBLE CAUSE

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.
Check the cause; eliminate the reason for the
jamming of the pump.
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.
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 and the environment do not exceed the
max. admissible values.
1.
Refer to section 2.2.
2.
Please contact the customer service department.
