Warranty
The EZ-ZONE

9001-registered processes and is backed by a three-
year warranty to the first purchaser for use, provid-
ing that the units have not been misapplied. Since
Watlow has no control over their use, and some-
times misuse, we cannot guarantee against failure.
Watlow’s obligations hereunder, at Watlow’s option,
are limited to replacement, repair or refund of pur-
chase price, and parts which upon examination prove
to be defective within the warranty period specified.
This warranty does not apply to damage resulting
from transportation, alteration, misuse or abuse. The
purchaser must use Watlow parts to maintain all
listed ratings.
