Remanns at its option will repair, replace a product or refund the purchase price once it determines that the product requires repair or replacement. For a product to be determined defective it must be sent to Remann's remanufacturing plant for inspection.

Any products that are not returned to Remanns remanufacturing to undergo inspection will not be covered by this warranty. All repairs and/or replacements to the products must first be authorized by Remanns Remanufacturing. Remanns will not pay for any unauthorized repairs. Incidental damage caused by the requested repair or by the removal of the product is not covered by the warranty.
