Warranty, liability and complaints

Section 7 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 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.
