6 Warranty

WORLDWIDE EXCEPT USA & CANADA

SUMMARY OF WARRANTY

Crown International, 1718 West Mishawaka Road, 
Elkhart, Indiana 46517-4095 U.S.A. warrants to 
you, the ORIGINAL PURCHASER and ANY SUB-
SEQUENT OWNER of each NEW Crown1 product, 
for a period of three (3) years from the date of pur-
chase 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 
Warranty.

Warranty is only valid within the country in which 
the product is 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 inten-
tional 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.

WHAT THE WARRANTOR WILL DO

We will remedy any defect, regardless of the rea-
son for failure (except as excluded), by repair, 
replacement, or refund. We may not elect refund 
unless you agree, or unless we are unable to pro-
vide 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 encumbrances. The refund will be equal 
to the actual purchase price, not including inter-
est, insurance, closing costs, and other finance 
charges less a reasonable depreciation on the 
product from the date of original purchase. War-
ranty work can only be performed at our autho-
rized service centers. We will remedy the defect 
and ship the product from the service center 
within a reasonable time after receipt of the defec-
tive product at our authorized service center. 

HOW TO OBTAIN WARRANTY SERVICE

You must notify your local Crown importer of 
your need for warranty service within the warranty 
period. All components must be shipped in the 
original box. 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 cen-
ter are not satisfactory, notify our authorized ser-
vice center immediately.

DISCLAIMER OF CONSEQUENTIAL AND 
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 corresponding changes in 
products previously manufactured.

LEGAL REMEDIES OF PURCHASER

No action to enforce this Crown Warranty shall be 
commenced after expiration of the warranty 
period.

THIS STATEMENT OF WARRANTY SUPERSEDES 
ANY OTHERS CONTAINED IN THIS MANUAL FOR 
CROWN PRODUCTS.                          9/07
