Section 9 Warranty and liability
The manufacturer warrants that the supplied product is free of
material and manufacturing defects and undertakes to repair or
replace any defective parts at zero cost to the owner.
The warranty period is 24 months. If a maintenance contract is
taken out within 6 months of purchase, the warranty period is
extended to 60 months.
With the exclusion of further claims, the supplier is liable for
defects, including the lack of assured properties, as follows: all
parts that, within the warranty period calculated from the day of the
transfer of risk, can be demonstrated to have become unusable or
that can only be used with significant limitations owing to
circumstances prior to transfer of risk, in particular due to incorrect
design, substandard materials or inadequate finish, shall be
repaired or replaced at the supplier's discretion. The identification
of such defects must be reported to the supplier in writing as soon
as possible, but no later than 7
days after the discovery of the fault.
If the customer fails to notify the supplier, the product is considered
approved despite the defect. Further liability for any direct or
indirect damages is not accepted.
If instrument-specific maintenance and servicing work prescribed
by the supplier is to be performed within the warranty period by the
customer (maintenance) or by the supplier (servicing) and these
requirements are not met, claims for damages resulting from
non-compliance with these requirements are rendered void.
Further claims, in particular for consequential damages, cannot be
made.
Wear and damage caused by improper handling, incorrect
installation or non-designated use are excluded from this clause.
The process instruments of the manufacturer have proven their
reliability in many applications and are therefore often used in
automatic control loops to enable the most economical and efficient
operation of the relevant process.
To avoid or limit consequential damage, it is therefore
recommended that the control loop be designed such that an
instrument malfunction results in an automatic changeover to the
backup control system. This guarantees the safest operating
condition both for the environment and the process.
