Graco Electronic Dispense Valve Warranty

Graco warrants all equipment manufactured by it and bearing its name to be free from defects in material and workmanship on the date
of sale to the original purchaser for use.  As purchaser’s sole remedy for breach of this warranty, Graco will, for a period of two (2) years
from the date of sale, repair or replace any part of the equipment proven defective,

 

including defects in the electronic meter control,

which will be repaired or replaced for two (2) years from the date of sale.  This warranty applies only when the equipment is installed,
operated and maintained in accordance with Graco’s written recommendations.

This warranty does not cover, and Graco shall not be liable for, any malfunction, damage or wear caused by faulty installation, misap-
plication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of non-Graco
component parts.  Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility with Graco equipment of
structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or
maintenance of structures, accessories, equipment or materials not supplied by Graco.

This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for
verification of the claim.  If the claimed defect is verified, Graco will repair or replace free of charge any defective parts.  The equipment
will be returned to the original purchaser transportation prepaid.  If inspection of the equipment does not disclose any defect in material
or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor and transportation.

Disclaimers and Limitations.  The terms of this warranty constitute purchaser’s sole and exclusive remedy and are in lieu of any other
warranties (express or implied),

 including warranty of merchantability or warranty of fitness for a particular purpose

, and of any

non-contractual liabilities, including product liabilities, based on negligence or strict liability.  Every form of liability for direct, special or
consequential damages or loss is expressly excluded and denied.  In no case shall Graco’s liability exceed the amount of the purchase
price.  Any action for breach of warranty must be brought within three (3) years of the date of sale

.

Equipment not covered by Graco Warranty.  Graco makes 

no warranty, and disclaims all implied warranties of merchantability

and fitness for a particular purpose

, with respect to accessories, equipment, materials, or components sold but not manufactured

by Graco

.  

These items sold, but not manufactured by Graco (such as electric motor, switches, hose, etc.) are subject to the warranty, if

any, of their manufacturer.  Graco will provide purchaser with reasonable assistance in making any claim for breach of these warran-
ties.
