WARRANTY 

 
Mars’ warranty coverage, period, extent,  and 
limitations apply to the product only. It does not apply 
to labor. Mars warrants that Mars product 1) Is free 
from defects in materials and workmanship and 2) 
Conforms to Mars’ published specifications.  The 
warranty period for Mars product except heated and 
custom models, is a five (5) year period commencing 
on its date of shipment.  The date on customer’s 
invoice is the date of shipment unless Mars or your 
reseller informs you and Mars otherwise. For heated 
products, the warranty period is an eighteen (18) 
month period and for custom products and 
accessories, the warranty period is twelve (12) 
months period commencing the date of shipment. 
Mars will provide free replacement of any part that 
fails as a result of a defect in material or 
manufacturer’s workmanship. 

Changes in 

operational specification parameters that are 
different from those provided on the original 
purchase order are not covered.  Mars  product  is 
inspected and tested before packaging and is 
shipped in working condition. The warranty for Mars 
product only covers free-of-charge replacement of 
failed parts. The warranty does not cover labor and 
transportation expenses that may be required to 
provide and to install replacement parts. Because in 
many instances, it is impossible to determine the 
cause of failure, customer may be responsible for 
transportation charges associated with replacement 
of failed part. Mars does not warrant uninterrupted or 
error-free operation of Mars product.  Under no 
circumstance is Mars liable for any of the following: 
1) Third-party claims against you for damages; or 2) 
Special, incidental, or indirect damages or for any 
economic consequential damages (including lost 
profits and savings), even if Mars, its suppliers, or its 
reseller is informed of their possibility. The warranty 
does not cover repair or exchange of Mars product 
resulting from misuse, accident, modification, 
unsuitable physical or operating environment, 
improper maintenance and installation by customer, 
or failure caused by a product for which Mars is not 
responsible. The warranty does not cover damages 
caused by mishandling during transportation.  The 
warranty  is voided by removal or alteration of Mars 
product or parts identification labels, by improper 
installation of product, and resulting non-compliance 
to federal, state,  and local codes and regulations. 
Additionally, Mars reserves the right to void the 
warranty for non-payment of invoice.
