We grant for the described product in the warranty receipt a war-
ranty of declared duration in the warranty receipt. The warranty
starts with the first start up, latest with the day of sale. A warranty
claim can be raised only by presentation of the fill in warranty
receipt together with the purchase receipt.
Our warranty extends only the removal of material defects or
production defects. Costs for removal and installation of the
complained product at the installation place, costs for the ride of
the mechanicians to the location and from the installation place
as well as costs for transport are not components of our war-
ranty. Complains caused by installation faults or operating faults,
unsuitable operation conditions, deficient care or improper efforts
of repair are out of the question of warranty as well as normal
wear. Hereby arised costs, especially costs for checking and
transport are bearing by the sender or operator of the pump. This
is also valid for an asserted warranty claim if a check results that
the unit works faultless and is free of defects. All products have a
high quality standard. Each product is defeated by a streng tech-
nical end control before delivery. If the unit still gives an occasion
for a legitimated complain, you have the claim of an appropriated
correction free of charge. Warranty repairs only must lead from
the manufacturer or an authorized agency. Trials of repair by the
customer or non-authorized persons during the warranty, causes
an extinguishing of the warranty. A warranty repair achieved by
us does not extend the warranty period. Replaced spare parts
give no reasons for a new warranty period. Extensive claims are
excluderd, especially such as diminution, change or compensa-
tion also for any kind of follow up damages.
To guarantee a quick transaction of a warranty claim, please re-
turn the product together with the warranty receipt, purchase re-
ceipt and declaration of defect carriage paid to the manufacturer
(for the adress see warranty receipt).
Claims caused by damages of transport could be only accepted,
if the damage is established or confirmed by delivery in the pres-
ence of the forwarder, parcel service, train or post.
