PRODUCT WARRANTY

SnyderGeneral  Corporation, hereinafter referred to as the
“Company,” warrants that it will provide, at the Company’s
option, either free replacement parts or free repair of com-
ponent parts in the event any product manufactured by the
Company and used in the United States proves defective in
material or workmanship within twelve (12) months from in-
itial startup or eighteen (18) months from the date shipped
by the Company, whichever comes first. For additional con-
sideration, the Company warrants that for four (4) years follow-
ing the initial warranty period it will provide, at the Company’s
option, free replacement parts for the motor-compressor, or,
free replacement for any integral component of the motor-
compressor which proves defective in material or workman-
ship. For an additional consideration, the Company warrants
that for nine (9) years following the initial warranty period it
will provide free replacement of the heat exchanger in gas-
fired or oil-fired furnaces which proves defective in material
and workmanship. (Extended warranties for motor-compres-
sors and heat exchangers are not applicable unless separately

purchased.)

THIS WARRANTY CONSTITUTES THE BUYER’S SOLE

REMEDY. IT IS GIVEN IN LIEU OF ALL OTHER WARRAN-

TIES. THERE IS NO IMPLIED WARRANTY OF MERCHAN-
TABILITY OR FITNESS FOR A PARTICULAR PURPOSE.
IN NO EVENT AND UNDER NO CIRCUMSTANCES SHALL
THE COMPANY BE LIABLE FOR INCIDENTAL OR CONSE-
QUENTIAL DAMAGES, WHETHER THE THEORY BE

BREACH OF THIS OR ANY OTHER WARRANTY, NEGLI-
GENCE OR STRICT TORT.

This parts warranty and the optional extended warranties

extend only to the original user. Of course, abuse, misuse,
or alteration of the product in any manner voids the Com-
pany’s warranty obligation. Neither the parts or extended war-

ranty obligates the Company to pay any labor or service costs

for removing or replacing parts, or any shipping charges.

Refrigerants, fluids, oils, and expendable items such as filters
are not covered by this warranty.

The extended warranties apply only to integral components

of the motor-compressor or heat exchanger, not to refrigerant
controls, electrical controls, or mechanical controls, or to
failures caused by failure of those controls.

Attached to this warranty is a requirement for equipment

containing motor-compressors and/or furnaces to report start-
up information. The registration form accompanying the pro-
duct must be completed and returned to the Company within
ten (10) days of original equipment start-up. If that is not  done.
the date of shipment shall be presumed to be the date of start-
up and the warranty shall expire twelve (12) months from that
date.

No person (including any agent, salesman, dealer or

distributor) has authority to expand the Company’s obligation
beyond the terms of this express warranty, or to state that the
performance of the product is other than that published by
the Company.
