SUMMARY OF WARRANTY

Crown International, 1718 West Mishawaka Road, Elkhart, Indiana 46517-4095 U.S.A. warrants to you, the ORIGINAL PURCHASER 
and ANY SUBSEQUENT OWNER of each NEW Crown1 product, for a period of three (3) years from the date of purchase by the original 
purchaser (the “warranty period”) that the new Crown product is free of defects in materials and workmanship, and we further warrant 
the new Crown product regardless of the reason for failure, except as excluded in this Crown Warranty.

Warranty is only valid within the country in which the product was purchased.

1 Note: If your unit bears the name “Amcron,” please substitute it for the name “Crown” in this warranty.

ITEMS EXCLUDED FROM THIS CROWN WARRANTY

This Crown Warranty is in effect only for failure of a new Crown product which occurred within the Warranty Period. It does not cover 
any product which has been damaged because of any intentional misuse, accident, negligence, or loss which is covered under any of 
your insurance contracts. This Crown Warranty also does not extend to the new Crown product if the serial number has been defaced, 
altered, or removed.

We will remedy any defect, regardless of the reason for failure (except as excluded), by repair, replacement, or refund. We may not elect 
refund unless you agree, or unless we are unable to provide replacement, and repair is not practical or cannot be timely made. If a 
refund is elected, then you must make the defective or malfunctioning product available to us free and clear of all liens or other encum-
brances. The refund will be equal to the actual purchase price, not including interest, insurance, closing costs, and other finance 
charges less a reasonable depreciation on the product from the date of original purchase. Warranty work can only be performed at our 
authorized service centers. We will remedy the defect and ship the product from the service center within a reasonable time after receipt 
of the defective product at our authorized service center. 

HOW TO OBTAIN WARRANTY SERVlCE

You must notify us of your need for warranty service  within the warranty period. All components must be shipped in a factory pack. 
Corrective action will be taken within a reasonable time of the date of receipt of the defective product by our authorized service center. 
If the repairs made by our authorized service center are not satisfactory, notify our authorized service center immediately.

DISCLAIMER OF CONSEQUENTIAL & INCIDENTAL DAMAGES

YOU ARE NOT ENTITLED TO RECOVER FROM US ANY INCIDENTAL DAMAGES RESULTING FROM ANY DEFECT IN THE NEW 
CROWN PRODUCT. THIS INCLUDES ANY DAMAGE TO ANOTHER PRODUCT OR PRODUCTS RESULTING FROM SUCH A DEFECT.

WARRANTY ALTERATIONS

No person has the authority to enlarge, amend, or modify this Crown Warranty. This Crown Warranty is not extended by the length of 
time which you are deprived of the use of the new Crown product. Repairs and replacement parts provided under the terms of this 
Crown Warranty shall carry only the unexpired portion of this Crown Warranty.

DESIGN CHANGES

We reserve the right to change the design of any product from time to time without notice and with no obligation to make correspond-
ing changes in products previously manufactured.

LEGAL REMEDIES OF PURCHASER

No action to enforce this Crown Warranty shall be commenced later than ninety (90) days after expiration of the warranty period.
