Warranty, Service and Repair

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 prod-

ucts (or components thereof) which FLOWLINE’s examination proves

to its satisfaction to be defective. FLOWLINE SHALL HAVE NO OB-

LIGATION 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 with-

out the original casing on the products. Moreover, this warranty becomes

immediately null and void if anyone other than service personnel autho-

rized by FLOWLINE attempts to repair the defective products.

Products which are thought to be defective must be shipped prepaid and

insured to FLOWLINE’s factory or a designated service center (the iden-

tity and address of which will be provided upon request) within 30 days

of the discovery of the defect. Such defective products must be accom-

panied by proof of the date of purchase.

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 rem-

edies, warranties, guarantees or liabilities, express or implied. EX-

CLUDED FROM THIS WARRANTY IS THE IMPLIED WARRANTY

OF FITNESS OF THE PRODUCTS FOR A PARTICULAR PURPOSE

OR USE AND THE IMPLIED WARRANTY OF MERCHANT ABIL-

ITY 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.

If FLOWLINE level transmitters or switches are used for process control

where failure of the transmitter or switch could result in personal injury

or property damage, an independent means such as a redundant FLOW-

LINE point level switch should be used. Where FLOWLINE level trans-

mitters or switches are used as a part of a pressure vessel or pipe, care

should be taken to independently protect against personal injury or prop-

erty damage should the FLOWLINE sensor fail or be mishandled. Con-

tact FLOWLINE or your local distributor for additional information.
