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 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.
Please note:
1. Should your device fail to function properly, please verify first whether an operating error or another
cause is present which cannot be attributed to a defect of the device.
2. In case you have to take or send in your defective device for repair, please be sure to enclose the
following documents:
− Sales receipt (sales slip).
− A description of the occurring defect (a description as accurate as possible will expedite the
repair work).
3. In case you have to take or send in your defective device for repair, please remove any attached
parts which do not belong to the original condition of the device. If any attached parts of this kind
should be missing upon the return of the device, we shall not be liable for them.
