WATLOW Series 733/734 Service Manual
Warranty
The Watlow Series 733/734 is warranted to be free
of defects in material and workmanship for 36
months after delivery to the first purchaser for use,
providing that the units have not been misapplied.
This excludes mechanical relays which are war-
ranted for 100,000 cycles.
Since Watlow has no control over their use, and
sometimes misuse, we cannot guarantee against
failure. Watlow's obligations hereunder, 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 damage resulting from transportation,
alteration, misuse, or abuse.
