Limited warranty

 

Attotech products are guaranteed against manufacturing defects for one year from the date of 
shipment. This warranty covers the cost of labor as well as parts, but does not cover the cost of 
transportation to and from our laboratories. Neither piezo electric transducers, nor seals or other 
disposable items are included in the warranty. The warranty does not apply when there has been 
obvious misuse or mistreatment by the user. Including use in conjunction with equipment which is 
electrically or mechanically incompatible, or when damage has been caused by attempted repairs 
by the user. Exposure of Attotech products to inappropriate chemicals also voids the warranty. 
Except as thus provided, we disclaim all warranties, express or implied, including any warranty of 
fitting for a particular purpose. Attotech HB will not assume responsibility for contingent liability 
through alleged failure(s) of its products. There are no warranties, express or implied, which 
extend beyond this description. Damages are limited strictly to repair or replacement of the 
products. Attotech expressly disclaims liability for incidental and consequential damages resulting 
from the use of the products.
