8. 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 wilful 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.

the inlet opening of the intake line including the
check valve are immersed into the liquids being
discharged;
c)
the check 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.
4.
Remove cause of clogging.
5.
