 products are warranted against defects 

in material and workmanship for a period of three 
years from the date of shipment, provided they are 
used in accordance with the ordering specifications 
and the instructions in this manual and that they are 
not subjected to abuse, physical damage or 
contamination. Products that do not operate properly 
during this period may be repaired or replaced at no 
charge. Repairs are normally warranted for one year 
or the balance of the original warrant, whichever is 
longer. 
See also paragraph 9 of the Conditions of sales. 
 
The warranty includes all initial and latent defects, 
random failures, and undeterminable internal causes. 
 
It excludes failures and damage caused by the 
customer, such as contamination, improper electrical 
hook-up, dropping etc. 
 
Re-conditioning of products primarily returned for 
warranty service that is partly or wholly judged non-

Bronkhorst High-Tech B.V. prepays outgoing freight 
charges when any party of the service is performed 
under warranty, unless otherwise agreed upon 
beforehand. However, if the product has been 
returned collect to our factory, these costs are added 
to the repair invoice. Import and/or export charges, 
foreign shipping methods/carriers are paid for by the 
customer.
