WFCO extends to the original owner a Two-Year Limited Product Warranty. 
This Warranty is in effect from the date of original purchase for a period of two 
(2) years. This Limited Warranty is extended specifically for and is limited to 
recreational vehicle application and is valid only within the continental United 
States, Alaska, Hawaii and the provinces of Canada. WFCO warrants to the 
owner that its products are free from defects in material and workmanship 
under normal use and service, based on its intended use and function. This 
Warranty is limited to the repair or replacement, at WFCO' s discretion, of any 
defective parts or defective assembly. Any implied warranties of merchantability 
or fitness for intended use are limited in duration unless applicable State Law 
provides otherwise. You may have other rights as specified by each individual 
state.

EXCLUSIONS and LIMITATIONS
The OEM Warranty specifically does not apply to the following:
Any WFCO product that has been repaired or altered by any unauthorized 
person. Any damage caused by misuse, faulty installation, testing, negligence 
or accident or any WFCO product installed in a commercial vehicle.
Any WFCO product whose serial number has been defaced, altered or removed.
Any WFCO product whose installation has not been in accordance with the 
WFCO written instruction. Any consequential damages arising from the loss of 
use of the product including, but not limited to, inconvenience, loss of service, 
loss of revenue, loss or damage to personal property and cost of all services 
performed in removing or replacing the WFCO product. Specifications are
subject to change without notice or obligation.

CONSUMER WARRANTY CLAIM PROCEDURE
Upon determination and validation by an authorized OEM dealer that a WFCO 
product has a defect, the dealer shall contact the WFCO warranty service 
number (877) 294-8997 and obtain a return goods authorization (RGA) number. 
This number shall appear on all correspondence with warranty service. Upon 
validation of the warranty, WFCO shall replace or repair the product with a like 
product. The RGA number shall be placed on the outside of the carton used to 
return the product, for ease of identification. Do not mark directly on the 
product. The product must be packaged properly to avoid further damage to 
the product, which could cause a non-warrantable condition.
