SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
INSTALLATION INSTRUCTIONS
VISUAL INSPECTION: Before inst alling the unit, check the container and machine for damage. Adamaged container is an indi-
cator 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. A water hardness test must be performed to determine if the HTS-11 (4730-003-28-03) scale prevention and corrosion control, needs to be
installed. Ahardness test kit is attached to the warning tag that is attached to the y-strainer
toward the front of the machine. If the hardness is higher than 5 GPG the HTS-11 (4730003-28-03) will need to be installed, please contact Jackson immediately to have this item
shipped to you.
WATER SUPPLY CONNECTION FOR MACHINES WITH A WATER HARDNESS
GREATER THAN 5 GPG: Ensure that you have read the section entitled “PLUMBING THE
DISHMACHINE” above before proceeding. Install the HTS-11 into the water line (1/2” ID
pipe size minimum) before the dishmachine line y-strainer using copper pipe. The HTS-11
must be installed vertically. Amounting bracket is provided to facilitate the venture metering
head to the wall. Observe proper inlet/outlet water directions. Flow directions are molded
into the top of the head. It is recommended that a water shut-off valve be installed before
the HTS-1 to allow access for servicing. Plumb from the HTS-1 1 outlet to the y-strainer using
copper pipe (or order the 1/2” ID flexible hose kit offered by Jackson). The water supply line
is to be capable of 20±5 PSI “flow” pressure at the recommended temperature indicated on
the data plate. See “Pressure Regulator” and “Shock Absorber” sections.
WATER SUPPLY CONNECTION FOR MACHINES WITH A WATER HARDNESS OF 5
GPG OR LESS:Ensure that you have read the section entitled “PLUMBING THE DISHMA-
CHINE” above before proceeding. Install the water supply line (1/2” ID pipe size minimum)
to the dishmachine line y-strainer using copper pipe (or order the 1/2” ID flexible hose kit
offered by Jackson). 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±5 PSI “flow” pressure at the recommended temperature indicated on the data plate.
PRESSURE REGULATOR: Do to areas where the water pressure fluctuates or is greater than the recommended pressure, it
is recommended installing a water pressure regulator. 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.

ELECTRICAL INSTALLATION INSTRUCTIONS
SHOCK ABSORBER: It is also recommended that a shock absorber (not supplied with the JPX-300 series models) 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.
CONNECTING THE DRAIN LINE: The JPX-300 series machines are a pumped (pressure) drain capable of pumping waste
water to a height of 24 inches from the floor to the kitchen’s drain system. The dishmachines are supplied with a 10 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.
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 front of the machine. Refer to the
data plate for machine operating 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 screws at the bottom of the kick panel;
open the door slightly while carefully lifting the kick panel
up and out of the way. Install 3/4” conduit into the prepunched holes in the back of the control box. Route power
wires and connect to power block and grounding lug.
Install the service wires (L1 and 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 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.
CHEMICAL CONNECTIONS: All chemical hookup locations are located on
the back of the dishmachine. Please refer to the drawing at the right for the
correct connection point. The JPX-300H/HC/HN dishmachines are supplied
with integral detergent and rinse aid chemical feeder pumps. The JPX-300L
dishmachine is supplied with integral detergent, rinse additive and sanitizer chemical feeder pumps.
Please refer to page 11 for instructions on priming the chemical feeder pumps.

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. Sanitizer in concentration is
caustic and may cause damage without dilution.
1. Verify that the proper chemical tube stiffener inlet is in the proper container.
2. Use the prime switches located at the top of the unit to prime each pump. The switches are clearly marked (“D”, “R”, and
“S”) as to what chemical feeder pump they are assigned to.
3. To prime the pumps, hold the switch in the momentary position until chemical can be observed entering the sump.
4. Detergent is dispensed as required during the wash cycle by the cam timer. The amount of detergent may need to be
increased or decreased depending on water quality and type of detergent. It is adjusted by changing the detergent cam on the
cam timer.
5. Rinse additive is dispensed as required into the final rinse. The amount of rinse aid may need to be adjusted depending on
water hardness and results. It can be changed by changing the rinse cam on the cam timer.
6. Sanitizer (either chlorine or iodine) is dispensed into the final rinse. The amount of sanitizer may need to be adjusted
depending on the concentration and type of sanitizer used. It is adjusted by changing sanitizer cam on the cam timer.
WARNING: Some of the chemicals used in dishwashing may cause chemical burns if they come in contact with
your skin. Wear protective gear when handling these chemicals. If you do come in contact with these chemicals, immediately flush the affected area with fresh water.

Detergent usage and water hardness are two factors that contribute greatly to how efficiently your dishmachine will operate.
Using detergent in the proper amount can become, in time, a source of substantial savings. A qualified water treatment specialist can tell you what is needed for maximum efficiency from your detergent, but you should still know some basics so you’ll
understand what they are talking about.
First, you must understand that hard water greatly effects the performance of the dishmachine. Water hardness is the amount
of dissolved calcium and magnesium in the water supply. The more dissolved solids in the water, the greater the water hardness. Hard water works against detergent, thereby causing the amount of detergent required for washing to increase. As you
use more detergent, your costs for operating the dishmachine will increase and the results will decrease. The solids in hard
water also may build-up as a scale on wash and rinse heaters, decreasing their ability to heat water. Water temperature is
important in removing soil and sanitizing dishes. If the water cannot get hot enough, your results may not be satisfactory. This
is why Jackson recommends that if you have installed the machine in an area with hard water, that you also install some type
of water treatment equipment to help remove the dissolved solids from the water before it gets to the dishmachine.
Second, hard water may have you adding drying agents to your operating cycle to prevent spotting, when the real problem is
deposited solids on your ware. As the water evaporates off of the ware, the solids will be left behind to form the spotting and
no amount of drying agent will prevent this. Again, using treated water will undoubtedly reduce the occurrences of this problem.
Third, treated water may not be suitable for use in other areas of your operation. For instance, coffee made with soft water may
have an acid or bitter flavor. It may only be feasible to install a small treatment unit for the water going into the dishmachine
itself. Discuss this option with your qualified water treatment specialist.
Even after the water hardness problems have been solved, there still must be proper training of dishmachine operators in how
much detergent is to be used per cycle. Talk with your water treatment specialist and detergent vendor and come up with a
complete training program for operators. Using too much detergent has as detrimental effects as using too little. The proper
amount of detergent must be used for job. It is important to remember that certain menu items may require extra detergent by
their nature and personnel need to be made aware of this. Experience in using the dishmachine under a variety of conditions,
along with good training in the operation of the machine, can go a long way in ensuring your dishmachine operates as efficiently as possible.
Certain dishmachine models require that chemicals be provided for proper operation and sanitization. Some models even
require the installation of third-party chemical feeders to introduce those chemicals to the machine. Jackson does not recommend or endorse any brand name of chemicals or chemical dispensing equipment. Contact your local chemical distributor for
questions concerning these subjects.
Some dishmachines come equipped with integral solid detergent dispensers. These dispensers are designed to accommodate
detergents in a certain sized container. If you have such a unit, remember to explain this to your chemical distributor upon first
contacting them.
As explained before, water temperature is an important factor in ensuring that your dishmachine functions properly. The data
plate located on each unit details what the minimum temperatures must be for either the incoming water supply, the wash tank
and the rinse tank, depending on what model of dishmachine you have installed. These temperatures may also be followed by
temperatures that Jackson recommends to ensure the highest performance from you dishmachine. However, if the minimum
requirements are not met, the chances are your dishes will not be clean or sanitized. Remember, a dish can look clean, but it
may not be sanitized. Instruct your dishmachine operators to observe the required temperatures and to report when they fall
below the minimum allowed. Aloss of temperature can indicate a much larger problem such as a failed heater or it could also
indicate that the hot water heater for your operation is not up to capacity and a larger one may need to be installed.
There are several factors to consider when installing your dishmachine to ensure that you get the best possible results from it
and that it operates at peak efficiency for many years. Discuss your concerns with your local chemical distributor and water
treatment specialist before there is a problem.

PREPARATION: Before proceeding with the start-up of the unit, verify the following:
1. The strainer is in place and is clean.
2. That the wash and rinse arms are screwed securely into place and that their endcaps are tight. The wash and rinse arms
should rotate freely.
3. Verify all chemical levels for machine chemical feeder pumps are correct.
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: For the initial fill, close the door and ensure that the MANUAL switch light is not on. Depress and
hold the START CYCLE switch until the auto light comes on and releases. For the initial fill, run the machine through 3 cycles
to fill the tub sump. The machine will run a partial cycle and fill to the bottom of the pan strainer. Open the door and verify that
the water level is correct.
NOTE: For the JPX-300H/JPX-300HC: Ensure the orange/white wires at the heater contactor are connected properly. They have been purposely disconnected at the factory to avoid damage to the heater element when there
is no water in the booster heater.
Hereafter, the water level is controlled by the timer that has been preset at the factory. Verify that there are no other leaks on
the unit before proceeding any further. The wash sump must be completely filled before operating the wash pump to prevent
damage to the component. Once the wash tub is filled, the unit is ready for operation.
The machine runs a complete cycle to drain and fill. If the machine is not allowed to drain, the water will build up inside the tub.
After the initial fill, the rinse water for the current cycle will become the wash water for the next cycle.
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 PREPARA TION: Refer to the section entitled “PREPARATION” at the top of this page and follow the instructions there. Afterwards, check that all of the chemical levels are correct and/or that there is plenty of detergent available for the
expected workload.
WARM-UP CYCLES: For a typical daily start-up, it is recommended to run the machine through 3 cycles to ensure that all of
the cold water is out of the system and to verify that the unit is operating correctly . To cycle the machine, ensure that the power
is on and that the tub has filled to the correct level.
Press the START CYCLE button and hold until the green auto light
is on and releases, the unit will start, run through the cycle,
and shut off automatically. Repeat this two more times. The unit should now be ready to proceed with the washing of ware.
WASHING ARACK OF WARE: T o wash a rack, open the door completely and slide the rack into the unit. Close the door, press
the START CYCLE button and hold until the green auto light is on and releases, the unit will start. 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 process will
then repeat itself.
OPERATIONAL INSPECTION: Based upon usage, the pan strainer may become clogged with soil and debris as the workday
progresses. Operators should regularly inspect the pan strainer to ensure it has not become clogged. If the strainer does, it will
reduce the washing capability of the machine. Instruct operators to clean out the pan strainer at regular intervals or as required
by work load.

OPERATION INSTRUCTIONS
13
SHUTDOWN AND CLEANING: At the end of the workday, close the door. Start a cycle. Wait approximately five seconds after
the green auto light comes on and then push the POWER OFF switch. This will put the machine in shutdown mode which will
let the machine drain completely prior to shutting off. Once the wash tub is drained and power light is off, remove he pan strainer. Remove soil and debris from the strainer and set to the side. Unscrew the wash and rinse arms from their manifolds.
Remove the endcaps and flush the arms with water. Use a brush to clean out the inside of the arms. If the nozzles appear to
be clogged, use a toothpick to remove the obstruction. Wipe the inside of the unit out, removing all soil and scraps. Reassemble
the wash and rinse arms and replace them in the unit. The arms only need to be hand tight, do not use tools to tighten them
down. Reinstall the strainer and close the door.
DELIMING OPERA TIONS: In order to maintain the dishmachine at its optimum performance level, it will be required to remove
lime and corrosion deposits on a frequent basis. Adeliming solution should be available from your detergent supplier. Read and
follow all instructions on the label of the deliming solution.
NOTE: If this machine is equipped with a HTS-11, scale prevention and corrosion control device, and lime is becoming a frequent problem, the cartridge needs to be replaced. To order a replacement cartridge (4730-003-28-04), call Jackson immediately to have one shipped to you.
To proceed with the deliming operation, fill the dishmachine and add the correct amount of deliming solution as recommended
by the deliming solution manufacturer. The water capacity of the tank can be verified on the specification sheet(s) of this manual.
Perform the following operations to delime the dishmachine:
1. Push Manual Switch on the front of the control panel.
2. Disconnect or turn off all chemical feeder pumps.
3. Close all doors (after adding the deliming solution).
4. Run the machine for the recommended period of time.
5. Press the Power Switch to turn the unit off and open the doors.
6. Wait five minutes, then inspect the inside of the machine. If the machine is not delimed, run another time cycle as per the
deliming solution’s instructions.
7. When clean, drain and re-fill the machine.
8. Run in MANUAL for 10 minutes to remove residual deliming solution.
9. Drain and re-fill the machine.

SECTION 3:
PREVENTATIVE MAINTENANCE
The dishmachines covered in this manual are designed to operate with a minimum of interaction with the operator. However,
this does not mean that some items will not wear out in time. Jackson highly recommends that any maintenance and repairs
not specifically discussed in this manual should be performed by QUALIFIED SERVICE PERSONNELONLY. Performing maintenance on your dishmachine may void your warranty if it is still in effect.
There are many things that operators can do to prevent catastrophic damage to the dishmachine. One of the major causes of
component failure has to do with prescrapping procedures. Adishmachine is not a garbage disposal; any large pieces of material that are put into the machine shall remain in the machine until they are either broken up (after spreading out on your ware!)
or physically removed. Strainers are installed to help catch debris, but they do no good if they are clogged. Have operators regularly inspect the pan strainers to ensure (1) that they are free of soil and debris and (2) they are laying flat in the tub.
When cleaning out strainers, do NOT beat them on waste cans. The strainers are made of metal and can be forgiving; but once
severe damage is done, it is next to impossible for the strainer to work in the way it was designed to. Wipe out strainers with
a rag and rinse under a faucet if necessary. For stubborn debris, a toothpick should be able to dislodge any obstructions from
the perforations. Always ensure that strainers are placed back in the machine before operation and that they lay flat in the tub.
You may wish to also refer to the page entitled “Detergent Control” in order to learn more about how your water hardness will
effect the performance of your machine. Hard water makes dishmachines work harder and decreases efficiency.
Again, it is important to remind operators that trying to perform corrective maintenance on the dishmachine could lead to larger problems or even cause harm to the operator. If a problem is discovered; secure the dishmachine using proper shut down
procedures as listed in this manual and contact a QUALIFIED SERVICE AGENCY.
Some problems, however, may having nothing to do with the machine itself and no amount of preventative maintanence is
going to help. Acommon problem has to do with temperatures being too low. Verify that the water temperatures coming to your
dishmachine match the requirements listed on the machine data plate. There can be a variety of reasons why your water temperature could be too low and you should discuss it with a QUALIFIED SERVICE AGENCY to determine what can be done.
By following the operating and cleaning instructions in this manual, you should get the most efficient results from your machine.
As a reminder, here are some steps to take to ensure that you are using the dishmachine the way it was designed to work:
1. Ensure that the water temperatures match those listed on the machine data plate.
2. Ensure that all strainers are in place before operating the machine.
3. Ensure that all wash and/or rinse arms are secure in the machine before operating.
4. Ensure that drains are closed/sealed before operating.
5. Remove as much soil from dishes by hand as possible before loading into racks.
6. Do not overfill racks.
7. Ensure that glasses are placed upside down in the rack.
8. Ensure that all chemicals being injected to machine have been verified as being at the correct concentrations.
9. Clean out the machine at the end of every workday as per the instructions in the manual.
10. Always contact a QUALIFIED SERVICE AGENCY whenever a serious problem arises.
11. Follow all safety procedures, whether listed in this manual or put forth by local, state or national codes/regulations.

These dishmachines are equipped with electrical
solenoid valves to allow for automatic fill and rinse. These
valves are designed to specific tolerances and design aspects
that must be met in order to function properly.
Jackson offers repair kits for replacing some of the
wear items associated with solenoid valves which will allow
you to save money in that replacement of these parts can take
place without removing the solenoid valve from the plumbing
assembly.
The instructions provided here are for maintenance
personnel only. Unauthorized persons should not attempt any
of the steps contained in these instructions.
Warning: many of the instructions and steps
within this document require the use of tools. Only authorized personnel should ever perform any maintenance
procedure on the dishmachine!
PREP
ARATION
1. Power must be secured to the unit at the service
breaker. Tag or lock out the service breaker to prevent accidental or unauthorized energizing of the machine.
2. Ensure that incoming water to the machine is
secured either by use of a shut-off valve or disconnecting the
incoming water line.
TOOLS REQUIRED
The following tools will be needed to perform this
maintenance evolution:
1. Small flathead screwdriver
2. Medium flathead screwdriver
2. Needle nose pliers
3. 5/16” nutdriver
4. Channel locks
5. 12” pipe wrench
TIME REQUIRED
It is estimated that it will take (1) person twenty minutes to perform this task, not including all of the items indicated in the section entitled “PREPARATION”.
IMPORTANT NOTES
1. Read these instructions thoroughly before attempting this maintenance evolution. Become familiar with the parts
and what actions need to be taken. This will save time in the
long run!
2. The procedures demonstrated in this manual are
shown being performed on an AJ-44C rack conveyor dishmachine. The actual maintenance steps, however, apply to any
Parker style solenoid valve found on a Jackson dishmachine.
STEPS
1. Remove the top screw with the 5/16” nutdriver. Remove the
screw and the data plate and set to the side.
2. With the top screw and data plate removed, grasp the solenoid coil and gently pull up. The coil should slide up, allowing
you to remove it from the valve bonnet. If you are wanting to
replace the coil, continue on with Step 3. If you are wanting to
replace some of the internal components of the valve, proceed
to step 12.
3. NOTE: Replacing the solenoid coil requires working with
the wiring of your machine. It is important that all wiring maintenance be performed by qualified personnel. Always verify
the wiring steps presented in this instruction with the schematic that shipped with the unit. A current schematic can also be
found in the unit’s installation manual. Before beginning any

to remove any foreign particles that might get lodged in the
threads and cause a leak. Severely damage threads should
not be repaired; instead it is recommended that the entire
valve should be replaced. These instructions do not provide
information on replacing the solenoid valve.
16. Note: Even though an O-ring may not appear damaged, it
is a good idea to go ahead and replace it if you have a new
one. This will help ensure that your valve remains leak-free in
the future!
17. Remove the diaphragm retainer and then the diaphragm
itself. Many problems associated with a solenoid valve can be
traced to a clogged pilot port in the diaphragm.
18. As indicated in the photo above, the extension hole can
become clogged. If it is difficult to clean out, you can use a
heated straight pin to push through the hole. The center hole,
the pilot port, must also be clear. If the diaphragm is torn or
bent in any way, it must be replaced.

19. Using the small flathead screwdriver, lift out the screen
retainer. Verify that the holes in it are free of clogs and debris.
20. Again using the small flathead screwdriver, carefully
remove the mesh screen from inside the valve body. The
screen should be taken and rinsed out to remove any debris
fouling it.
21. With the mesh screen removed, look down into the valve
and verify it is not clogged. Remove any foreign objects from
the valve body that would obstruct flow.
22. Reassemble the valve, reversing the steps needed to take
it apart. Replace defective replacement parts with new parts
from ordered kits. Ensure that components are sufficiently
tightened to prevent leakage.
AFTER MAINTENANCE ACTIONS
Reconnect the incoming water (if disconnected) and
turn on. Then restore power to the unit. Run the unit for at
least 10 minutes to ensure there are no leaks. If any problems
arise please contact Jackson.

VACUUM BREAKER REPAIR PARTS KIT
25
These dishmachines are equipped with vacuum
breakers to serve as back-flow prevention devices. ASSE
requirements specify what type of back-flow prevention is necessary on dishmachines. Vacuum breakers, unlike air gaps,
have certain parts that have specific tolerances and design
aspects that must be met in order to function properly.
Jackson offers repair kits for replacing some of the
wear items associated with vacuum breakers which will allow
you to save money in that replacement of these parts can take
place without removing the vacuum breaker from the plumbing assembly.
The instructions provided here are for maintenance
personnel only. Unauthorized persons should not attempt any
of the steps contained in these instructions.
Warning: many of the instructions and steps
within this document require the use of tools. Only authorized personnel should ever perform any maintenance
procedure on the dishmachine!
PREPARATION
1. Power must be secured to the unit at the service
breaker. Tag or lock out the service breaker to prevent accidental or unauthorized energizing of the machine.
2. Ensure that incoming water to the machine is
secured either by use of a shut-off valve or disconnecting the
incoming water line.
TOOLS REQUIRED
The following tools will be needed to perform this
maintenance evolution:
1. Small flathead screwdriver
2. Needle nose pliers
TIME REQUIRED
It is estimated that it will take (1) person twenty minutes to perform this task, not including all of the items indicated in the section entitled “PREPARATION”.
IMPORTANT NOTES
1. Read these instructions thoroughly before attempting this maintenance evolution. Become familiar with the parts
and what actions need to be taken. This will save time in the
long run!
STEPS
1. Note: These instructions only apply to vacuum breakers
(1/2” NPT and 3/4” NPT) as pictured below. The repair kits
indicated in these instructions will only work on those style of
back-flow preventers. If you have a machine with a different
style of vacuum breaker, contact Jackson about replacement
components.
2. Note: Even though the photos in these instructions show a
vacuum breaker that has been removed from the plumbing
assembly , these maintenance steps could be performed with it
installed so long as the requirements in the section entitled
“PREPARATION” have been met.
3. Remove the top cap by gripping firmly and turning to the
left. The cap should come off after a few turns.
4. Set the cap to the side.
5. Using the needle nose pliers, gently lift out the plunger and
set to the side. Examine the brass seating surface inside the
vacuum breaker. The plunger is required to sit flat on this surface so it must be free of defects, imperfections and the like. If
there is debris, remove it. If it is chipped or cracked then the
vacuum breaker must be replaced. Failure to do so may result
in the vacuum breaker not working according to its design and
could result in damage to the dishmachine.

6. Your repair kit comes with a new plunger. Examine the old
one and ensure that the mating surface is not damaged or cut.
Also inspect the rubber seal on the top of the plunger to
ensure it is in good condition and not torn.
7. If any of these conditions are present, replace the old
plunger with the new one from your kit. Verify that the new
plunger is also free from defects. If it is not, contact Jackson
immediately.
8. The plunger should drop into the vacuum breaker and seat.
Ensure it is not flipped upside down (the orange seal ring
should be up towards the top of the vacuum breaker).
9. Pick up the cap and examine it. With a soft towel, remove
any grit, grime or debris that may have gotten caught in the
threads of both the cap retainer or the vacuum breaker body.
There is an O-ring that should be present on the cap retainer
as well. Regardless of the condition of the plunger, this O-ring
should be replaced once the cap is removed. Using a small
flathead screwdriver, remove the old O-ring.
10. With the new O-ring in place, screw the cap back on the
vacuum breaker body. The cap needs to only be hand tight
(snug).
AFTER MAINTENANCE
ACTIONS
1. Reconnect the incoming water (if disconnected)
and turn on. Then restore power to the unit. Run the unit for
at least 10 minutes to ensure there are no leaks. If any problems arise please contact Jackson.
