circuit breaker sizes as listed in the NEC 2002 Edition. Local codes may require more stringent protection than what is dis-  
played 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 with-  
out notice at any given time.

INSTALLATION INSTRUCTIONS  
FOR SERVICE PERSONNEL: Jackson MSC Inc. provides technical support for all of the dishmachines detailed in this manu-  
al. We strongly recommend that you refer to this manual before making a call to our technical support staff. Please have this  
manual with you when you call so that our staff can refer you, if necessary, to the proper page. Technical support is available  
from 8:00 a.m. to 5:00 p.m. (EST), Monday through Friday. Technical support is not available on holidays. Contact technical  
support toll-free at 1-888-800-5672. Please remember that technical support is available for service personnel only. Non-ser-  
vice personnel should refer to the list of provided service agencies in this manual for local service support.  
VISUAL INSPECTION: Before installing the unit, check the container and machine for damage. A damaged 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, undam-  
aged 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 miss-  
ing parts from the machine. This may not be obvious at first. If it is discovered that an item is missing, contact Jackson imme-  
diately 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  
Raise  
Lower  
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.  
Frame with Adjustable Foot  
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 drain for the models covered in this manual are gravity discharge drains. All piping from  
the 1 1/2” FNPT connection on the waste accumulator must be pitched (1/4” per foot) to the floor or sink drain. All piping from  
the machine to the drain must be a minimum 1 1/2” NPT 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.  
WATER SUPPLY CONNECTION: Ensure that you have read the section entitled  
Adjusting screw  
Locking nut  
“PLUMBING THE DISHMACHINE” above before proceeding. Install the water supply  
line (3/4” 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 capa-  
ble of 20±5 PSI “flow” pressure at the recommended temperature indicated on the data  
plate.  
If the water level is too low or too high, check the incoming water pressure. It should be  
20 ± 5 PSI. Too high of pressure results in too much water; too low of pressure results  
in too little water. To adust the regulator, loosen the nut at the top, this will allow you to  
screw or unscrew the adjustment. With a screwdriver, turn the adjuster clockwise to  
increase pressure or counter clockwise to decrease it.  
Incoming Plumbing Connection  
In areas where the water pressure fluctuates or is greater than the recommended pres-  
sure, 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.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS  
INSTALLATION INSTRUCTIONS (CONTINUED)  
It is also recommended that a shock absorber (not supplied with the models covered in this manual) be installed in the incom-  
ing water line. This prevents line hammer (hydraulic shock), induced by the solenoid valve as it operates, from causing dam-  
age 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.  
STEAM LINE CONNECTION: The 300XS is designed to use low pressure steam as a source of heat for wash tank water. The  
machine comes with lines by which the source steam needs to be connected. Connect all steam lines to the machine as all  
applicable codes provide. See machine data plate for information concerning steam flow pressure.  
CHEMICAL DISPENSING EQUIPMENT: The 300XLT machine requires that a separate chemical feeder be connected to it to pro-  
vide the required detergent and sanitizer. This feeder needs to be able to operate against a head of 25 PSI and provide 1.79 ml of  
a 10% Chlorine sanitizer per minute.  
ELECTRICAL POWER CONNECTION: Electrical and grounding connections must comply with the applicable portions of the  
Terminal Block  
Ground Lug  
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 operating requirements, machine  
voltage, total amperage load and serial number.  
To install the incoming power lines, open the control box. This will require taking  
a phillips head screwdriver and removing the one(1) screw on the front cover of  
the control box. 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 (L1, L2 & L3 (3 phase models only.)) to the appropriate  
terminals as they are marked on the terminal block. Install the grounding wire  
into the lug provided.  
Electrical Connection  
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 incom-  
ing power at the terminal block and ensure it corresponds to the voltage listed on the data plate. If not, contact a qualified ser-  
vice agency to examine the problem. Do not run the dishmachine if the voltage is too high or too low. Shut off the service break-  
er 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.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS  
DETERGENT CONTROL  
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 spe-  
cialist 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 hard-  
ness. 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 prob-  
lem.  
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 effi-  
ciently 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 recom-  
mend 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. A loss 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.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS  
OPERATION INSTRUCTIONS  
PREPARATION: Before proceeding with the start-up of the unit, verify the following:  
1. The pump intake, and wash tank strainers are in place and is clean.  
2. The drain stopper is installed.  
3. 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.  
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. Verify that the gas supply to the machine is on as well.  
FILLING THE WASH TUB: Ensure that the delime switch is in the NORMAL position, and place the power switch into the ON posi-  
tion. The models covered in this manual should fill automatically and shut off when the appropriate level is reached (the gas burn-  
ers should also automatically ignite as well). Verify that the drain stopper is preventing the wash tub water from pouring out exces-  
sively. There will probably be some slight leakage from the drain hole. Verify that there are no other leaks on the unit before pro-  
ceeding any further. The wash tub must be completely filled before operating the wash pump to prevent damage to the compo-  
nent. Once the wash tub is filled, the unit is ready for operation.  
The water level was set at the factory. If the water level is not at the level noted above, it will require adjustment. Check to ensure  
that the recommended water pressure is being supplied to the machine (20±5 PSI). If the water pressure is correct then the fill  
valve will need adjustment.  
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 wash-  
ing the ware. Scraps should be removed from ware prior to being loaded into a rack.  
Pre-rinsing and pre-soaking are recommended, 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  
there. Afterwards, check that all of the chemical levels are correct and/or that there is plenty of detergent available for the expect-  
ed 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. Lift the doors and the cycle light will illuminate. When the light goes out, close the  
doors, 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 A RACK OF WARE: To wash a rack, open the doors completely (being careful for hot water that may drip from the  
doors) and slide the rack into the unit. Close the doors and the unit will start automatically. Once the cycle is completed, open the  
door (again watching for the dripping hot water) and remove the rack of clean ware. Replace with a rack of soiled ware and close  
the doors. The process will then repeat itself.  
OPERATIONAL INSPECTION: Based upon usage, the wash tank strainer may become clogged with soil and debris as the work-  
day progresses. Operators should regularly inspect the wash tank 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 wash tank strainer at regular intervals  
or as required by work load.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS  
OPERATION INSTRUCTIONS (CONTINUED)  
SHUTDOWN AND CLEANING: At the end of the workday, close the doors. When the unit completes the cycle, turn the power  
switch to the OFF position and open the doors. Manually remove the drain stopper from the tub and allow the tub to drain (NOTE:  
the wash tank water will be hot so caution is advised). Once the wash tub is drained, remove the wash tank strainer and the pump  
suction strainer. Remove soil and debris from the strainer and set to the side. Unscrew the wash and rinse arms from their mani-  
folds. 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 strainers and close the doors.  
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 deion-  
ized water or other aggressive fluids will void the manufacturer's warranty.

SECTION 3: PREVENTATIVE MAINTENANCE  
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 PERSONNEL ONLY. Performing main-  
tenance on your dishmachine may void your warranty if it is still in effect, so if you have a question or concern, do not hesitate  
to contact one of the QUALIFIED SERVICE AGENCIES listed in the back of this manual.  
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. A dishmachine is not a garbage disposal; any large pieces of mate-  
rial 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 reg-  
ularly 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 larg-  
er 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 as listed in the back of this manual.  
Some problems, however, may having nothing to do with the machine itself and no amount of preventative maintanence is  
going to help. A common 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 tem-  
perature 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.

Loosening the conduit nut  
Prying open the coil wire cover  
7. Using a pair of channel locks, gently loosen the conduit  
retaining ring for the conduit nut. Once it is loosened, use your  
fingers to unscrew and remove it.  
4. When replacing the coil, ensure that when removing the coil  
wire cover that care is taken not to damage the wires inside.  
Using the medium flathead screwdriver, gently use it to open  
the cover enough to where it could be pulled off.  
8. Pull the conduit away and discard the bad coil. Take the  
new coil and attach the conduit, reinstall & tighten the conduit  
nut, and pull the wires through so that you will be able to wire  
the valve back up.  
9. Reconnect the wires from the conduit to the wires from the  
solenoid as they had been connected previously. Ensure that  
the wire nuts are on tight.  
10. Slide the coil wire cover back on, taking care not to dam-  
age the wires.  
11. If you are done performing maintenance on the valve, con-  
tinue on to step 22. Otherwise, please go on to step 12.  
Straightening the wires  
5. Once the coil wire cover has been removed and set to the  
side, take the internal wires and pull them out straight.  
Loosening the valve bonnet  
12. To remove the valve bonnet, grasp it with the jaws of the  
pipe wrench and turn to the left. Note: on some models you  
may have to remove the valve in order to perform this and any  
further steps. Be careful not to damage the plumbing assem-  
bly. Only use the pipe wrench enough to where you can spin  
the valve bonnet off with your hand.

Removing the valve bonnet  
13. Slowly remove the valve bonnet. Note: The spring for the  
plunger is located directly under the bonnet and may come  
free if you are not careful. Remove the plunger, spring and  
valve bonnet and place to the side.  
Removing the diaphragm  
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.  
Removing the O-ring  
14. Remove the O-ring and inspect it. If it has any tears or cuts  
or excessive flat spaces, it should be replaced.  
Pointing out the extension hole  
15. Examine the threads for the valve bonnet. Check them for  
scoring or signs of damage. Take a cloth and clean them out  
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.  
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.  
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!

VACUUM BREAKER REPAIR PARTS KIT  
These dishmachines are equipped with vacuum  
STEPS  
breakers to serve as back-flow prevention devices. ASSE  
requirements specify what type of back-flow prevention is nec-  
essary 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 plumb-  
ing assembly.  
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.  
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 autho-  
rized personnel should ever perform any maintenance  
procedure on the dishmachine!  
PREPARATION

incoming water line.  
3. Remove the top cap by gripping firmly and turning to the  
left. The cap should come off after a few turns.  
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 min-  
utes to perform this task, not including all of the items indicat-  
ed in the section entitled “PREPARATION”.  
IMPORTANT NOTES  
Removing the cap  
1. Read these instructions thoroughly before attempt-  
ing this maintenance evolution. Become familiar with the parts 4. Set the cap to the side.  
and what actions need to be taken. This will save time in the  
long run!  
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 sur-  
face 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.

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.  
Removing the plunger  
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.  
Replacing the 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 prob-  
lems arise please contact Jackson.

SECTION 6: PARTS SECTION  
WASH MOTORS  
The 300X models covered in this manual come supplied with various wash motor assemblies (a wash motor assembly  
includes the wash motor and the pump end), depending on the characteristics of the machine. To ensure that you order the  
correct wash motor assembly for the model you are servicing, please refer to the following table:  
Important note: When servicing a wash  
motor, it is important to refer to the wiring  
schematic found on the motor, to ensure that  
the motor is wired correctly. Different manu-  
facturers of motors may not use the same  
wire color codes and therefore, your new  
motor, which may have been built by some-  
one different than who built your original  
motor, may not connect using the same wires.  
Always refer to the wiring diagrams on the  
motor you are installing. If the motor you are  
installing has had the schematic removed,  
contact Jackson MSC immediately for techni-  
cal support.

When servicing plumbing components, take care not to damage the threads of each individual item. Damaged threads can  
cause leaks and loss of pressure, which could adversely effect the performance of the 300X dishmachine. It is strongly rec-  
ommended that teflon thread tape, used in conservative amounts, be applied to threads when joining components together. It  
is not advised to use thread sealing compounds, sometimes referred to as “pipe dope”. Compounds can be ejected from the  
threads during the tightening process and become lodged in key components, thereby rendering them useless. Some of the  
components include the solenoid valve and the pressure gauge isolation ball valve.
