8. 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 pur-
chase, 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 prop-
erties 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.
