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, dur ing 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.
TRAVEL LIMITATIONS
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.

INSTALLATION INSTRUCTIONS
VISUAL INSPECTION: Before installing the unit, check the container and machine for damage. A damaged container is an indicator that there may be some damage to the machine. If there is
damage to both the container and machine, do not throw away the
container. The dishmachine has been inspected and packed at
the factory and is expected to arrive to you in new, undamaged
condition. However, rough handling by carriers or others may
result in there being damage to the unit while in transit. If such a
situation occurs, do not return the unit to Jackson; instead, contact
the carrier and ask them to send a representative to the site to
inspect the damage to the unit and to complete an inspection
report. You must contact the carrier within 48 hours of receiving
the machine. Also, contact the dealer through which you purchased the unit.
UNPACKING THE DISHMACHINE: Once the machine has been
removed from the container, ensure that there are no missing
parts from the machine. This may not be obvious at first. If it is discovered that an item is missing, contact Jackson immediately to
have the missing item shipped to you.
LEVEL THE DISHMACHINE: The dishmachine is designed to
operate while being level. This is important to prevent any damage to the machine during operation and to ensure the best
results when washing ware. The unit comes with adjustable bullet
feet, which can be turned using a pair of channel locks or by hand
if the unit can be raised safely. Ensure that the unit is level from
side to side and from front to back before making any connections.
PLUMBING THE DISHMACHINE: All plumbing connections must
comply with all applicable local, state, and national plumbing
codes. The plumber is responsible for ensuring that the incoming
water line is thoroughly flushed prior to connecting it to any component of the dishmachine. It is necessary to remove all foreign
debris from the water line that may potentially get trapped in the
valves or cause an obstruction. Any valves that are fouled as a
result of foreign matter left in the water line, and any expenses
resulting from this fouling, are not the responsibility of the manufacturer.
CONNECTING THE DRAIN LINE: The JP-24 series machines
have a pumped (pressure) drain capable of pumping waste water
to a height of 24 inches from the floor to the kitchen’s drain system. These dishmachines are supplied with an 8 foot long hose
that extends from the rear side of the machine. There must also
be an air gap between the machine drain line and the floor sink or
drain. If a grease trap is required by code, it should have a flow
capacity of 12 gallons per minute.
WATER SUPPLY CONNECTION: Ensure that you have read the
section entitled “PLUMBING THE DISHMACHINE” above before
proceeding. Install the water supply line (1/2” pipe size minimum)
to the dishmachine line strainer using copper pipe. It is recommended that a water shut-off valve be installed in the water line
between the main supply and the machine to allow access for service. The water supply line is to be capable of 20 PSI “flow” pressure at the recommended temperature indicated on the data plate.
In areas where the water pressure fluctuates or is greater than the
recommended pressure, it is recommended that a water pressure
regulator be installed.
Do not confuse static pressure with flow pressure. Static pressure
is the line pressure in a “no flow” condition (all valves and services
are closed). Flow pressure is the pressure in the fill line when the
fill valve is opened during the cycle.
It is also recommended that a shock absorber (not supplied with
the JP-24 series model) be installed in the incoming water line.
This prevents line hammer (hydraulic shock), induced by the solenoid valve as it operates, from causing damage to the equipment.
PLUMBING CHECK: Slowly turn on the water supply to the
machine after the incoming fill line and the drain line have been
installed. Check for any leaks and repair as required. All leaks
must be repaired prior to placing the machine in operation.
ELECTRICAL POWER CONNECTION: Electrical and grounding
connections must comply with the applicable portions of the
National Electrical Code ANSI/NFPA 70 (latest edition) and/or
other electrical codes.
Disconnect electrical power supply and place a tag at the disconnect switch to indicate that you are working on the circuit.
The dishmachine data plate is located on the right side and to the
front of the machine. Refer to the data plate for machine operat ing requirements, machine voltage, total amperage load and serial number.
To install the incoming power lines, remove the kick panel. This
will require taking a phillips head screwdriver and removing the
two(2) screws at the bottom of the kick plate; then carefully lifting
the kickplate up and out of the way. Install 3/4” conduit into the
pre-punched holes in the back of the control box. Route power
wires and connect to power block and grounding lug. Install the
service wires (L1and L2) to the appropriate terminals as they are
marked on the terminal block. Install the grounding wire into the
lug provided.
It is recommended that “DE-OX” or another similar anti-oxidation
agent be used on all power connections.
VOLTAGE CHECK: Ensure that the power switch is in the OFF
position and apply power to the dishmachine. Check the incoming
power at the terminal block and ensure it corresponds to the volt age listed on the data plate. If not, contact a qualified service
agency to examine the problem. Do not run the dishmachine if the
voltage is too high or too low. Shut off the service breaker and
mark it as being for the dishmachine. Advise all proper personnel
of any problems and of the location of the service breaker.
Replace the control box cover and tighten down the screws.
