ALL NEW JACKSON DISHWASHERS ARE WARRANTED TO THE ORIGINAL PURCHASER TO BE FREE FROM
DEFECTS IN MATERIAL OR WORKMANSHIP, UNDER NORMAL USE AND OPERATION FOR A PERIOD OF (1) ONE
YEAR FROM THE DATE OF PURCHASE, BUT IN NO EVENT TO EXCEED (18) EIGHTEEN MONTHS FROM THE DATE
OF SHIPMENT FROM THE FACTORY.
Jackson MSC agrees under this warranty to repair or replace , at its discretion, any original part which fails under normal use due to faulty
material or workmanship during the warranty period, providing the equipment has been unaltered, and has been properly installed, maintained and operated in accordance with the applicable factory instruction manual furnished with the machine and the failure is reported to
the authorized service agency within the warranty period. This includes the use of factory specified genuine replacement parts, purchased
directly from a Jackson authorized parts distributor or service agency. Use of generic replacement parts may create a hazard and void warranty certification.
The labor to repair or replace such failed part will be paid by Jackson MSC, within the continental United States, Hawaii and Canada, during
the warranty period provided a Jackson MSC authorized service agency, or those having prior authorization from the factory, performs the
service. Any repair work by persons other than a Jackson MSC authorized service agency is the sole responsibility of the customer. Labor
coverage is limited to regular hourly rates, overtime premiums and emergency service charges will not be paid by Jackson MSC.
Accessory components not installed by the factory carry a (1) one year parts warranty only. Accessory components such as table limit switches, pressure regulators, pre rinse units, etc. that are shipped with the unit and installed at the site are included. Labor to repair or replace
these components is not covered by Jackson MSC.
This warranty is void if failure is a direct result from shipping, handling, fire, water, accident, misuse, acts of god, attempted repair by unauthorized persons, improper installation, if serial number has been removed or altered, or if unit is used for purpose other than it was originally intended.
TRAVELLIMITATIONS
Jackson MSC limits warranty travel time to (2) two hours and mileage to (100) one hundred miles. Jackson MSC will not pay for travel time
and mileage that exceeds this, or any fees such as those for air or boat travel without prior authorization.
WARRANTY REGISTRATION CARD
The warranty registration card supplied with the machine must be returned to Jackson MSC within 30 days to validate the warranty.
REPLACEMENT PARTS WARRANTY
Jackson replacement parts are warranted for a period of 90 days from the date of installation or 180 days from the date of shipment from the
factory, which ever occurs first.
PRODUCT CHANGES AND UPDATES
Jackson MSC reserves the right to make changes in design and specification of any equipment as engineering or necessity requires.
THIS IS THE ENTIRE AND ONLY WARRANTY OF JACKSON MSC. JACKSON’S LIABILITY ON ANY CLAIM OF ANY KIND, INCLUDING
NEGLIGENCE, WITH RESPECT TO THE GOODS OR SERVICES COVERED HEREUNDER, SHALL IN NO CASE EXCEED THE PRICE
OF THE GOODS OR SERVICES OR PART THEREOF WHICH GIVES RISE TO THE CLAIM.
THERE ARE NO WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING FOR FITNESS OR MERCHANTABILITY, THATARE NOT SET
FORTH HEREIN, OR THAT EXTEND BEYOND THE DURATION HEREOF. UNDER NO CIRCUMSTANCES WILL JACKSON MSC BE
LIABLE FOR ANY LOSS OR DAMAGE, DIRECT OR CONSEQUENTIAL, OR FOR THE DAMAGES IN THE NATURE OF PENALTIES,
ARISING OUT OF THE USE OR INABILITY TO USE ANY OF ITS PRODUCTS.
ITEMS NOT COVERED
This warranty does not cover cleaning or deliming of the unit or any component such as, but not limited to, wash arms, rinse arms or strain-
ers at anytime. Nor does it cover adjustments such as, but not limited to timer cams, thermostats or doors, beyond 30 days from the date
of installation. In addition, the warranty will only cover the replacement of wear items such as curtains, drain balls, door guides or gaskets
during the first 30 days after installation. Also, not covered are conditions caused by the use of incorrect (non-Commercial) grade detergents,
incorrect water temperature or pressure, or hard water conditions.

NOTE: Typical Electrical Circuit is based upon (1) 125% of
the full amperage load of the machine and (2) typical
fixed-trip circuit breaker sizes as listed in the NEC 2002
Edition. Local codes may require more stringent protection than what is displayed here. Always verify with your
electrical service contractor that your circuit protection is
adequate and meets all applicable national and local
codes. These numbers are provided in this manual simply for reference and may change without notice at any
given time.
