WARRANTY CLAIM PROCEDURE

If customer believes one or more components of the Change'Air product is defective or 
working improperly, customer shall contact its local Change'Air agent and request the name 
and address of a Change'Air authorized service provider in its geographical area. Customer 
shall compile all available information concerning the parts and necessary labour required to 
rectify the defect and return the Change'Air product to normal operating condition. Customer 
shall complete a warranty claim form and fax it, with proof of shipment date, to Change'Air 
(Canadian fax # (519) 866-3798, USA Office fax # (517) 676-4367) prior to proceeding with 
any repair to the Change'Air product. If Change'Air determines customer's warranty claim is 
within the prescribed time period, Change'Air will promptly return the warranty claim form to 
customer with instructions concerning the procedure to be followed to repair the defect, 
together with a warranty authorization number. NO WORK TO RECTIFY ANY DEFECT FOR 
WHICH WARRANTY COVERAGE IS SOUGHT BY CUSTOMER SHALL BE COMPLETED 
UNTIL CHANGE'AIR HAS ISSUED A WARRANTY AUTHORIZATION NUMBER. All 
directions set out in such form must be carefully followed by customer. Change'Air shall ship 
in stock replacement components to customer within 2 business days. Costs of such

warranty claim is valid. Receipts for any labor or field supplied parts must also be returned to 
Change'Air's head office. Warranty authorization number must be quoted on all 
correspondence, returns and claims. Reimbursement will only be made for field supplied 
parts and labor if authorized by Change'Air on the warranty claim form. If Change'Air 
determines that the alleged defective component was either (i) not defective or (ii) the defect 
was a result of an event or action which voided the warranty, customer shall be entitled to 
retain the replacement component but shall be responsible to pay Change'Air for the 
replacement component, plus the costs of repairs and labor if applicable.
