WARRANTY

Flowline warrants to the original purchaser of its products that such
products will be free from defects in material and workmanship under
normal use and service for a period which is equal to the shorter of
one year from the date of purchase of such products or two years from
the date of manufacture of such products.

This warranty covers only those components of the products which
are non-moving and not subject to normal wear. Moreover, products
which are modified or altered, and electrical cables which are cut to
length during installation are not covered by this warranty.

Flowline’s obligation under this warranty is solely and exclusively
limited to the repair or replacement, at Flowline’s option, of the prod­ucts (or components thereof) which Flowline’s examination proves to
its satisfaction to be defective. FLOWLINE SHALL HAVE NO
OBLIGATION FOR CONSEQUENTIAL DAMAGES TO
PERSONAL OR REAL PROPERTY, OR FOR INJURY TO ANY
PERSON.

This warranty does not apply to products which have been subject to
electrical or chemical damage due to improper use, accident, negli­gence, abuse or misuse. Abuse shall be assumed when indicated by
electrical damage to relays, reed switches or other components. The
warranty does not apply to products which are damaged during ship­ment back to Flowline’s factory or designated service center or are
returned without the original casing on the products. Moreover, this
warranty becomes immediately null and void if anyone other than
service personnel authorized by Flowline attempts to repair the defec-

tive products.
Products which are thought to be defective must be shipped prepaid
and insured to Flowline’s factory or a designated service center (the
identity and address of which will be provided upon request) within
30 days of the discovery of the defect. Such defective products must
be accompanied by proof of the date of purchase.

Flowline further reserves the right to unilaterally wave this warranty
and to dispose of any product returned to Flowline where:

a. There is evidence of a potentially hazardous material present

with product.

b. The product has remained unclaimed at Flowline for longer than

30 days after dutifully requesting disposition of the product.

THERE ARE NO WARRANTIES WHICH EXTEND BEYOND
THE DESCRIPTION ON THE FACE OF THIS WARRANTY. This
warranty and the obligations and liabilities of Flowline under it are
exclusive and instead of, and the original purchaser hereby waives, all
other remedies, warranties, guarantees or liabilities, express or
implied. EXCLUDED FROM THIS WARRANTY IS THE IMPLIED
WARRANTY OF FITNESS OF THE PRODUCTS FOR A
PARTICULAR PURPOSE OR USE AND THE IMPLIED
WARRANTY OF MERCHANT ABILITY OF THE PRODUCTS.

This warranty may not be extended, altered or varied except by a writ­ten instrument signed by a duly-authorized officer of Flowline, Inc.
