9. 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.

case of a defective floating switch, please contact
customer service.
5. Eliminate blocking of the check valve (non-return
valve) or replace, if damaged.

2. Refer to section 3.3.
3. Refer to section 3.4.
4. Make sure that mains voltage matches that
indicated on the type plate.
