Warranty and liability

Warranty and liability
The manufacturer warrants that the product supplied is free of material and
manufacturing defects and undertakes the obligation to repair or replace any
defective parts at zero cost.
The warranty period for instruments is 24 months. If a service contract is
taken out within 6 months of purchase, the warranty period is extended to
60 months.
With the exclusion of the further claims, the supplier is liable for defects including
the lack of assured properties as follows: all those 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 due to a
situation present prior to the transfer of risk, in particular due to incorrect design,
poor materials or inadequate finish will be improved or replaced, at the supplier's
discretion. The identification of such defects must be notified to the supplier in
writing without delay, however at the latest 7 days after the identification 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 defined 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
due to the failure to comply with the requirements are rendered void.
Any further claims, in particular claims for consequential damages cannot be
made.
Consumables and damage caused by improper handling, poor installation or
incorrect use are excluded from this clause.
The manufacturer process instruments are of proven reliability in many
applications and are therefore often used in automatic control loops to provide
the most economical possible operation of the related process.
To avoid or limit consequential damage, it is therefore recommended to design
the control loop such that a malfunction in an instrument results in an automatic
change over to the backup control system; this is the safest operating state for the
environment and the process.
