LIMITED WARRANTY STATEMENT

Taco, Inc. will repair or replace without charge
(at the company’s option) any Taco 00 Series
circulator or circulator part which is proven
defective under normal use within three (3) years
from the date of manufacture.

In order to obtain service under this warranty, it
is the responsibility of the purchaser to promptly
notify the local Taco stocking distributor or Taco
in writing and promptly deliver the subject product
or part, delivery prepaid, to the stocking distrib-
utor. For assistance on warranty returns, the
purchaser may either contact the local Taco
stocking distributor or Taco. If the subject prod-
uct or part contains no defect as covered in this
warranty, the purchaser will be billed for parts
and labor charges in effect at time of factory
examination and repair.

Any Taco product or part not installed or operated
in conformity with Taco instructions or which
has been subject to misuse, misapplication, the

addition of petroleum-based fluids or certain
chemical additives to the systems, or other
abuse, will not be covered by this warranty.

If in doubt as to whether a particular substance
is suitable for use with a Taco product or part, or
for any application restrictions, consult the
applicable Taco instruction sheets or contact
Taco at (401-942-8000).

Taco reserves the right to provide replacement
products and parts which are substantially similar
in design and functionally equivalent to the
defective product or part. Taco reserves the right
to make changes in details of design, construc-
tion, or arrangement of materials of its products
without notification.

TACO OFFERS THIS WARRANTY IN LIEU OF
ALL OTHER EXPRESS WARRANTIES. ANY
WARRANTY IMPLIED BY LAW INCLUDING
WARRANTIES OF MERCHANTABILITY OR
FITNESS IS IN EFFECT ONLY FOR THE DURA-

TION OF THE EXPRESS WARRANTY SET
FORTH IN THE FIRST PARAGRAPH ABOVE.

THE ABOVE WARRANTIES ARE IN LIEU OF
ALL OTHER WARRANTIES, EXPRESS OR
STATUTORY, OR ANY OTHER WARRANTY
OBLIGATION ON THE PART OF TACO.

TACO WILL NOT BE LIABLE FOR ANY SPE-
CIAL, INCIDENTAL, INDIRECT OR CONSE-
QUENTIAL DAMAGES RESULTING FROM THE
USE OF ITS PRODUCTS OR ANY INCIDENTAL
COSTS OF REMOVING OR REPLACING
DEFECTIVE PRODUCTS.

This warranty gives the purchaser specific
rights, and the purchaser may have other rights
which vary from state to state. Some states do
not allow limitations on how long an implied
warranty lasts or on the exclusion of incidental
or consequential damages, so these limitations
or exclusions may not apply to you.
