ELECTRICAL REQUIREMENTS  
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.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS  
INSTALLATION INSTRUCTIONS  
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 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 plumb-  
ing 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 machine to  
Adjusting screw  
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 30 gallons per minute.  
Locking nut  
WATER SUPPLY CONNECTION: Ensure that you have read the sec-  
tion entitled “PLUMBING THE DISHMACHINE” above before proceed-  
ing. Install the water supply line (1/2” pipe size minimum) to the dish-  
machine 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 25 PSI “flow” pressure at the recommended temperature  
indicated on the data plate.  
Incoming Plumbing Connection  
In areas where the water pressure fluctuates or is greater than the recommended pressure, it is suggested that a water pres-  
sure regulator be installed. The models covered in this manual do come with water pressure regulators as standard equipment.  
Please notify Jackson immediately if this component is not present on your machine.  
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) 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.  
GAS CONNECTIONS: Some machines covered in this manual are designed to use gas as an outside source of heat for wash  
tank water. The machines come with connections by which an outside source needs to be connected. Connect all incoming gas  
lines in accordance with the gas booster manufacturer’s instructions. Ensure that all applicable codes and regulations are  
adhered to.

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.  
VENTILATION OF DISHMACHINE: The dishmachine should be located with provisions for venting into an adequate exhaust  
hood or ventilation system. This is essential to permit efficient removal of the condensation exhaust. Ensure that the exhaust  
system is acceptable in accordance with all applicable codes and standards.  
NOTE: Any damage that is caused by steam or moisture due to improper ventilation is NOT covered under the  
warranty.  
This units covered in this manual have the following exhaust requirements:  
Load End:  
Unload End:  
200 CFM  
400 CFM  
The exhaust system must be sized to handle this volume for the dishmachine to operate as it was designed to.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS  
DELIMING OPERATIONS  
DELIMING OPERATIONS: 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. A deliming solution should be available from your detergent supplier. Read and  
follow all instructions on the label of the deliming solution.  
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 various tanks of the dishmachine can be verified on the spec-  
ification sheet(s) of this manual.  
Perform the following operations to delime the dishmachine:  
1. Turn the NORMAL/DELIME switch on the back of the control box to the DELIME position.  
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.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS  
SIDE LOADER INSTALLATION & OPERATION INSTRUCTIONS  
This accessory assists in the delivery of a full dish rack from the break down (scrapping) table to the dishmachine. It will con-  
vert the direction of travel 90°. Since the Side Loader is shipped mounted on the conveyor dishwasher there is no additional  
installation required for this option. As it is operated mechanically by the dishwasher it does not require any plumbing or elec-  
trical connections.  
This Side Loader does not require or add any additional electrical or mechanical devices to the unit which could create opera-  
tional or maintenance problems. As designed the drive mechanism is powered by the conveyor drive motor on the dishma-  
chine. An extension on the pawl bar provides the drive to push the racks into the unit.  
PREPARATION: Before proceeding with the start-up of the unit, verify that the Side Loader pan strainer is installed.  
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.  
WASHING A RACK OF WARE: Once a rack is fully loaded it should be positioned against the front of the dish table. The rack  
should then be moved into the Side Loader until it activates the actuator switch. Once the the machine is started, it should pull  
the rack through the machine and push it out the unload end. Once a rack has started through, you may put another rack in.  
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  
become clogged, it will reduce the washing capability of the machine. Instruct operators to clean out the pan strainer at regu-  
lar intervals or as required by work load.  
SHUTDOWN AND CLEANING: At the end of the workday, remove the pan strainer and clean as required. Wipe out the inside  
of the Side Loader and then reinsert the strainer.

SECTION 2: INSTALLATION & OPERATION INSTRUCTIONS  
DISHMACHINE OPERATING INSTRUCTIONS  
PREPARATION: Before proceeding with the start-up of the unit, verify the following:  
1. Close door(s) on dishmachine.  
2. Close the drain valve(s).  
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: Ensure that the delime switch is in the NORMAL position, and place the power switch into the ON  
position. The machine should fill automatically and shut off when the appropriate level is reached (just below the pan strainer).  
The wash tub 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.  
Machines equipped with prewash sections should not be run without water in those sections. This can cause  
damage to components.  
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  
hat 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 instruc-  
tions there. Afterwards, check that all of the chemical levels are correct and/or that there is plenty of detergent available for the  
expected workload.  
WASHING A RACK OF WARE: To wash a rack, simply slide a rack of soiled ware into the load end of the machine. Once the  
the machine is started, it should pull the rack through the machine and push it out the unload end. Once a rack has started  
through, you may put another rack in.  
OPERATIONAL INSPECTION: Based upon usage, the pan strainers may become clogged with soil and debris as the work-  
day progresses. Operators should regularly inspect the pan strainers to ensure they have not become clogged. If the strainers  
do, they will reduce the washing capability of the machine. Instruct operators to clean out the pan strainers at regular intervals  
or as required by work load.  
NOTE: On units equipped with prewash sections operators should also take the time to inspect the prewash section  
strainers and clean them as required by workload.  
SHUTDOWN AND CLEANING: At the end of the workday, place the power switch in the OFF position and open the door(s).  
Open the drain valves and allow the machine to drain completely. Remove the pawl bar assembly (clean as required). Remove  
the pan strainers and, if equipped, the prewash strainers, run off sheets and scrap basket strainer. Remove the wash and, if  
equipped, the prewash arms and verify that the nozzles and arms are free from obstructions. Flush the arms with fresh water.  
Remove the pump suction strainers and clean out as required. Remove the rinse tray assembly and clean. Remove the cur-  
tains and scrub with a mild detergent and warm water. Wipe out the inside of the unit and then reassemble with the compo-  
nents previously removed.

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 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 Jackson.  
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 Jackson.  
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 Jackson 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.
