12. 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), mechanical shaft seals, membranes and
pressure switch 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.

ELIMINATION
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.
5. Eliminate causes of dry-running.
1. Have the membrane or the entire pressure
tank replaced by qualified staff.
2. Use the tank valve to increase the
pressure until it reaches a value of 1.5 bar.
Before that, please open a consumer in the
pressure line (e.g. a faucet) to depressurise
the system.
3. Refer to section 2.2.
4. Eliminate the cause of blocking the check
