Section 9

Warranty and liability

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.
