Product warranty
Emerson warrants its Penberthy products
as designed and manufactured to be free
of defects in the material and workmanship
for a period of one year after the date of
installation or eighteen months after the date
of manufacture, whichever is earliest. Emerson
will, at its option, replace or repair any products
which fail during the warranty period due to
defective material or workmanship.
Prior to submitting any claim for warranty
service, the owner must submit proof of
purchase to Emerson and obtain written
authorization to return the product. Thereafter,
the product shall be returned to Emerson, with
freight paid.
This warranty shall not apply if the product has
been disassembled, tampered with, repaired or
otherwise altered outside of Emerson's factory
or if it has been subject to misuse, neglect or
accident.
The responsibility of Emerson hereunder is
limited to repairing or replacing the product
at its expense. Emerson shall not be liable
for loss, damage or expenses related directly
or indirectly to the installation or use of
its products, or from any other cause or
for consequential damages. It is expressly
understood that Emerson is not responsible
for damage or injury caused to other products,
buildings, personnel or property, by reason of
the installation or use of its products.
This is Emerson’s sole warranty and in lieu of
all other warranties, expressed or implied which
are hereby excluded, including in particular all
warranties of merchantability or fitness for a
particular purpose.
This document and the warranty contained
herein may not be modified and no other
warranty, expressed or implied, shall be made
by or on behalf of Emerson unless made in
writing and signed by the company's general
manager or director of engineering.
