Warranty
The EZ-ZONE
®
PM is manufactured by ISO 9001-registered processes and is backed by a three-year warran-
ty to the first purchaser for use, providing that the units have not been misapplied. Since Watlow has no con-
trol over their use, and sometimes misuse, we cannot guarantee against failure. Watlow’s obligations hereun-
der, at Watlow’s option, are limited to replacement, repair or refund of purchase price, and parts which upon
examination prove to be defective within the warranty period specified. This warranty does not apply to dam-
age resulting from transportation, alteration, misuse or abuse. The purchaser must use Watlow parts to main-
tain all listed ratings.
