Warranty, liability and complaints

HACH LANGE GmbH 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.

HACH LANGE GmbH 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.
