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 dish-
I
machine has been inspected and packed at the factory and is expect-
N
ed to arrive to you in new, undamaged condition. However, rough handling by carriers or others may result in there being damage to the unit
S
while in transit. If such a situation occurs, do not return the unit to
T
Jackson; instead, contact the carrier and ask them to send a repre-
R
sentative to the site to inspect the damage to the unit and to complete
U
an inspection report. You must contact the carrier within 48 hours of
C
receiving the machine. Also, contact the dealer through which you pur-
T
chased the unit.
I
UNPACKING THE DISHMACHINE: Once the machine has been
O
removed from the container, ensure that there are no missing parts
N
from the machine. This may not be obvious at first. If it is discovered
S
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 JPX-140 model covered in
this manual has a gravity discharge drain. Remove the drain plug from
the tub and the unit will drain itself. The unit comes with a flexible drain
hose that should be connected to the drain. The drain hose connection must drain downward and away from the machine.
vice, the final water line connection to the machine should be using a
length of flexible hose, suitable for the pressure and temperature of
the incoming water. 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 A5 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 suggested that a water pressure regulator be installed. The JPX series units do not come with water pressure
regulators as standard equipment.
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
JPX series units) 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.
Refer to the data plate for machine operating requirements,
machine voltage, total amperage load and serial number.
To install the incoming power lines for the JPX-140, route the power
lines through the grommet located in the rear AT THE TOP OF THE
MACHINE.
The drain for the JPX-160 & JPX-200, is a pumped discharge drain.
Both of these dishmachines must be drained into a stand pipe (like a
household washing machine). If they are not, they will siphon themselves empty. The stand pipe for the JPX-160 is between 20 and 24
inches tall. The stand pipe for the JPX-200 is between 24 and 28 inches tall. All piping from the machine to the drain must be a minimum 1”
I.P.S. and shall not be reduced.
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 5 gallons per minute.
PRIMING THE DRAIN LINE: For the JPX-160 and JPX-200 models,
prime the drain pump before use when the machine is full of water.
Lower the end of the drain hose and allow some water to drain from
the hose. Raise the end of the hose and connect it to its installation
position.
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
to the vacuum breaker on the back of the machine. For ease of ser-
WARNING: do not attempt to route incoming power lines
to the dispenser terminal block located at the bottom of
the JPX-140! Contact your authorized Jackson service agency or
Jackson technical service if there are any questions.
To install the incoming power lines for the JPX-160 & JPX-200 route
the power lines through the grommet located at the rear of the
machine towards the bottom. Install the service wires (L1, L2 &
Ground) to the appropriate terminals on the terminal block. 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 voltage 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.

Warning: Some of the chemicals used in dishwashing may cause chemical burns if they come in contact with your skin.
CHEMICAL DISPENSING EQUIPMENT
INSTRUCTION
S
This page does not apply to the JPX-140 dishmachine. This unit is not supplied with chemical pumps.
The JPX-160 and JPX-200 dishmachines are supplied with detergent and rinse additive chemical feeder pumps.
TO PREPARE PUMPS FOR OPERATION
Locate the open ends of the chemical tubes, insert the end of each tube onto the hub on the brass weight, and place each one in the
appropriate container.
A. Red Tubing = Detergent
B. Blue Tubing = Rinse Aid
PRIMING CHEMICAL FEEDER PUMPS
Chemical feeder pumps need priming when the machine is first installed or if for some reason the chemical lines have been removed
and air is allowed to enter.
CAUTION: Water must be in the sump and wash tank prior to the dispensing of chemicals.
1. Verify that the proper chemical tube inlet is in the correct container.
2. The detergent pump shall prime itself, provided there is sufficient chemical available.
3. Detergent is automatically dispensed as required during the wash cycle.
4. When it is required to fill the rinse agent tubes, e.g. on installation or if the container has been allowed to empty, the system may be
primed as follows:
a) Ensure a cycle is not in progress.
b) Press and hold the drain switch until “rinse-prime” appears in the display.
c) On models with drain pump the message “draining” will appear first. The message “rinse-prime” will appear after a fur-
ther few seconds. DO NOT release the switch when the “draining” message is showing, as this will start a drain cycle.
If this is accidentally done, switch off to cancel the drain cycle.
d) The rinse-agent pump will run until the switch is released.
e) Observe the rinse agent travelling along the tube. Release the switch when the tubing is full.
Wear appropriate protective gear when handling these chemicals. If you do come in contact with these chemicals flush
the area with fresh water.
This equipment is not recommend for use with deionized water or other aggressive fluids. Use of deionized water or
other aggressive fluids will result in corrosion and failure of materials and components. Use of deionized water or other
aggressive fluids will void the manufacturer's warranty.

6. Ensure that the wash arms are installed and secure.
POWER UP: To energize the unit, turn on the power at the service
breaker. The voltage should have been previously verified as
being correct. If not, the voltage will have to be verified.
FILLING THE WASH TUB:
JPX-140: Put the Blue Mode Switch in the STANDBY (up) posi-
tion. Ensure that the door is closed completely and place the
Power Switch in the ON position (the switch should illuminate).
The unit will begin to fill with water in both the wash tank and the
rinse tank.
JPX-160/JPX-200: For the initial fill, put the Power Switch in the
ON position and the AUTO/STANDBY Switch in STANDBY. Close
the door. The unit will automatically fill.
Note: Depending upon the wash temperature, the unit may go into
a FAST HEAT cycle. The machine will fill and drain water from the
rinse tank into the wash tank to get the wash temperature up to
the minimum (150° F) temperature.
The unit will stop filling once the correct level is attained. Ensure
that the unit is level and that incoming flow pressure is 20A5 PSI.
To prevent a cycle from starting after the door is closed, the Mode
Switch must be turned to “STANDBY” before the door is closed.
WARM UP CYCLES: Warm-up cycles are not required on the
JPX-140 dishmachine. When the machine reaches the proper
operating temperatures, the blue “READY” light on the front panel
will be illuminated.
WARE PREPARATION: Proper preparation of ware will help
ensure good results and less re-washes. If not done properly,
ware may not come out clean and the efficiency of the dishmachine will be reduced. It is important to remember that a dishmachine is not a garbage disposal and that simply throwing
unscraped dishes into the machine simply defeats the purpose
altogether of washing the ware. Scraps should be removed from
ware prior to being loaded into a rack. Pre-rinsing and pre-soaking are good ideas, especially for silverware and casserole dishes. Place cups and glasses upside down in racks so that they do
not hold water during the cycle. The dishmachine is meant not
only to clean, but to sanitize as well, to destroy all of the bacteria
that could be harmful to human beings. In order to do this, ware
must be properly prepared prior to being placed in the machine.
DAILY MACHINE PREPARATION: Refer to the section entitled
“PREPARATION” at the top of this page and follow the instructions
and/or that there is plenty of detergent available for the expected
workload.
WASHING A RACK OF WARE:
JPX-140: To wash a rack of ware, open the door completely
(being careful of for hot water that may drip from the top of the
unit), manually load the detergent into the wash chamber, and
slide the rack into the unit. Wait until the blue “READY” light on the
front panel is illuminated, indication that the water in the machine
has been heated to the proper operating temperature. Put the
STANDBY Switch into the the AUTO (down) position. Close the
door and the unit will start automatically. Once the cycle is com
pleted, open the door (again watching for dripping hot water) and
remove the rack of clean ware and allow ware to air dry. Replace
then repeat itself.
JPX-160/JPX-200: Once the display indicates “unit ready”, open
the door. Place the rack of soiled ware in the unit. Put the
AUTO/STANDBY Switch in the AUTO position. Select the desired
wash cycle length (2 or 4 minutes) by placing the Cycle Switch in
Close the door. The machine will start automatically. Once the
cycle is completed, open the door and remove the rack of clean
ware. Replace with a rack of soiled ware and close the door. The
cycle will begin again.
OPERATIONAL INSPECTION: Based upon usage, the wash
strainers may become clogged with soil and debris as the work
day progresses. Operators should regularly inspect the wash
will reduce the washing capability of the machine. Instruct opera
tors to clean out the wash strainer at regular intervals or as
required by work load.
SHUTDOWN AND CLEANING: At the end of the workday, close
the door. Wait until the cycle is complete and the MODE Switch
lamp is out. Move the MODE Switch UP into the STANDBY posi
tion, open the door to remove the last rack of ware. On pumped
drain machines, the RIGHT hand switch is blue. On units supplied
with a drain stopper, remove the drain stopper and put in a safe
place. (NOTE: The wash tank water will be hot so caution is
advised). Close the door. Press and hold down the Drain Switch
until the message “DRAINING” appears. IMMEDIATELY release
the switch and the drain cycle will start. The display will tell you
when the cycle is complete. Move the POWER Switch to Off posi
tion.

Remove the lower deflector washer (B) and clean. Notice how the
washer for the lower arm is installed with the lip up. This is very
important. If the deflector washer is not re-installed the same way,
wash performance will suffer tremendously. The upper deflector
washer (C) is only removable by removing the screws that attach
it to the top of the unit. In the event this reflector is removed to be
cleaned, make sure it is reattached with the lip facing downward
away from the top of the unit as shown in the picture below.

TROUBLESHOOTING SECTION
TROUBLESHOOTING
WARNING: Inspection, testing and repair of electrical equipment should be performed only by qualified service personnel. Certainprocedures in this section require electrical tests or measurements while power is applied to the machine. Exercise extreme caution
at all times. If test points are not easily accessible, disconnect power, attach test equipment and reapply power to test. When replac
ing electrical parts, disconnect power at source circuit breaker.
Problem: The tank does not fill up, machine does not start, or the dishmachine does not rinse.
1. Check that the water supply valve is open.
2. Check the water softener supply and connections.
3. Check the connections and fuses of the supply.
4. Examine the air vessel at the rear right of the wash tank. When the machine is empty, the lower edge of this vessel must not be
touching the water remaining in the tank. This situation can be avoided by a small adjustment to the feet or legs, to tilt the machine
slightly forwards.
Problem: The tank only fills up very slowly.
1. Check that the water supply is giving good pressure.
2. Check that the water line pressure during the fill or rinse is in the range of 15 to 25 PSI. If it is lower, ask your dealer to fit a boost
er pump to increase pressure.
3. Check that the rinse jets are not blocked by limescale or solid wastes.
4. Check if water hoses are trapped or kinked.
5. Check if the bushing at the center of the wash/rinse arm assemblies are loose or missing - this allows dirt into the rinse jets, which
may be blocked.
Problem: Water marks on glasses.
1. Use correct chemicals, which do not produce foam and which are specially designed for this type of commercial dishmachine.
2. Check that rinse jets are not blocked and the water pressure is adequate.
3. Check the water hardness. If there is any sign of grey or brown deposits on the inside of the tank or on the wash elements, you
probably have hard water. Ask your dealer to install a water softener.
Problem: Wash arms do not rotate freely.
1. Disassemble the wash arms and carefully clean, as described above. Check for signs of limescale deposit; a water softener may
be required.
a pump to increase the pressure.
3. Check if the deflector disc is missing or is upside down (should be the same way up as a saucer).
4. Check if the bushes at the center of the rotating arm assemblies are loose or missing - this allows dirt into the rinse jets, may be
blocked.
