Conveyor Switch Chart:
The chart above lists the conveyor switches and their func­tions, depending on the direction of travel for the machine. As you can see, when you change the direction of the conveyor, you must also alter the way the conveyor switches operate.
There is no need to remove the switches, only to change the wiring inside the heater box.
34. Note: Before beginning any part of this maintenance evo­lution that deals with the wiring of the machine, ensure that it is performed by qualified technicians only. Always refer to the machine schematic, located inside the control box, for any questions.
Wash Switch #1 and the Rinse Switch need to have their wire positions changed on the terminal board pictured above. Locate the gray/yellow wire for Wash Switch #1 (do not con­fuse it with the gray/yellow wire for Wash Switch #2) and the orange/yellow wire for the Rinse Switch. Exchange their posi­tions on the terminal board.
35. Verify that the plumbing has been reassembled correctly and that the hole cover weldment has been replaced and none of the gaskets are torn or pinched as this could lead to leaking when the machine operates.
35. Re-install the heater box cover.

AFTER MAINTENANCE ACTIONS
1. Reconnect the incoming water and drain lines and then restore power to the unit. Run the unit for at least 1/2 hour to ensure there are no leaks. Test the unit with an empty rack to ensure that it pulls the rack all of the way through the unit. If any problems arise you can contact your Jackson rep­resentative.
2. Replace the front dress panel once the unit is ready for service again.
SPECIAL NOTES
1. There is a possibility that you may be required to shorten or lengthen the conduit and wire lengths for the inlet solenoid on the rinse plumbing once it is moved. This work should be performed by qualified technicians who will do the work according to applicable local, state and national codes. Questions concerning this should be directed to your Jackson representative.

This accessory assists in the delivery of a full dish rack from the break down (scrapping) table to the dishmachine. It will con­vert 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 elec­trical connections.
This Side Loader does not require or add any additional electrical or mechanical devices to the unit which could create opera­tional or maintenance problems. As designed the drive mechanism is powered by the conveyor drive motor on the dishma­chine. 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 PREPARA TION: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.
OPERATIONALINSPECTION: 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 regu­lar 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.

CONCEALED DAMAGE OR MISSING P
ARTS:
IMPORTANT: FOR YOUR PROTECTION, PLEASE READ AND OBSERVE THE FOLLOWING:
This steam booster has been thoroughly inspected and carefully packed before leaving our warehouse. Concealed loss or damage means loss or damage which does not become apparent until the booster has been unpacked. The
contents may be damaged in transit due to rough handling even though the carton may not show external damage. If it is found that the shipment has concealed damage, PLEASE DO NOT RETURN IT TO JACKSON, but notify the carrier
(within 48 hours) asking them to send their agent to fill out an inspection report. Save the cartons so he may inspect them and be sure to note in the report any black marks, creases, tears, crushed corners or any other marks indicating rough handling. Also, notify your JACKSON dealer immediately.
If it is discovered that there are missing parts, please notify your JACKSON dealer immediately.
EQUIPMENT MOUNTING:
Your booster should come pre-assembled and will require that it be permanently mounted in place. The platform has pre­punched holes to allow for mounting to the installation floor. NOTE: The D226 Booster must be properly mounted and level before being used. Once the platform is secure to the floor, attach the water and steam lines in accordance with local and national codes.
PLUMBING:
NOTE: ALL CONNECTIONS MUST COMPLY WITH ALL APPLICABLE LOCAL, STATE AND NATIONAL PLUMBING CODES.
The plumber is responsible for ensuring that the water line is THOROUGHLY FLUSHED BEFORE connecting it to any manu- al or solenoid valve. It is necessary to remove all foreign matter such as chips (resulting from cutting or threading pipes), pipe joint compound or, if soldered fittings are used, bits of solder or cuttings from the lines. This debris, if not removed, may lodge in the valves and render them inoperative.
The D226 Booster is designed to take incoming water from a minimum temperature of 110°F to approximately 180°F for use in the final rinse of your Jackson dishmachine. In order to do this, water is supplied to the booster and is heated by tubes carry­ing 15-25 PSIG flow steam. Heat is transferred from the steam into the water, raising the temperature.
Install condensate drains in accordance with applicable codes. The D226 Booster is designed to operate at a water flow rate of 20 ±5 PSI. The assembly comes with a water pressure reg-
ulator, which is preset at the factory. However, adjustment may be required so ensure that you verify the the flow pressure before beginning operations. See the instructions regarding adjustment and maintenance of the water pressure regulator for more information.
WARNING: The D226 Booster is designed to heat water to a minimum of 180°F and is extremely hot during operations. Advise personnel of the dangers associated with touching booster components as burns or severe injury can occur.
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.

ELECTRICAL:
WARNING: Electrical and grounding connections must comply with applicable portions of the National Electrical Code
ANSI / NFPA70 (latest edition) and/or other electrical codes.Disconnect electrical power supply and place a tag or lock at the disconnect switch to indicate that you are working on the circuit.
To connect the incoming power, run the conduit for power wires through the open hole in the back of the control box. Connect the power wires to the terminal block as it is labeled (L1 and L2). Run the ground wire to the grounding lug marked “GND”. Tight connections and conduit nuts and close the control box by putting the cover on and securing with the 10-32 screws.
OPERA
TION:
WARNING: The heat exchanger used in the D226 Booster system is a pres-
sure vessel with very precise operating parameters. Safety equipment such as relief valves should never be tampered with or disabled. These devices are meant to protect the equipment and the operator from harm, damage and death.
1. Ensure that water, steam and any condensate drains are connected to the booster.
2. Start the water flow first, open the condensate drains and then begin steam flow.
3. On the control box, press the power switch and put it in the ON position. The power light should illuminate. The unit should run normally now.
WARNING: Do not shock the system by applying the steam before the water. This can cause damage to the booster. The following explanation describes the operation of the D226 Booster. NOTE: This explanation assumes that water and steam have been connected to the machine.
1. When the power switch (S1) is placed in the ON position, power is provided to both the power light (E1) and the thermostat (TS1).
2. The thermostat (TS1) will close when the water falls below the minimum setpoint, energizing the steam solenoid light (E2) and the steam solenoid (FS1).
3. The steam solenoid (FS1) will remain open, allowing steam into the booster, until the water temperature reaches the desired temperature. At that point, the thermostat (TS1) will open, de-energizing the steam solenoid (FS1) and the steam solenoid light (E2).
IMPORTANT: Please remember that all of the components in the control box are under line voltage (208-240 volts). Under no circumstance is the control box cover to be removed or opened during normal operations!
SHUTDOWN (FOR SER
VICE ONLY):
WARNING: The D226 Booster is designed to heat water to a minimum of 180°F and is extremely hot during operations.
Advise personnel of the dangers associated with touching booster components as burns or severe injury can occur.
1. Turn the power switch to the OFF position. The power light should extinguish.
2. Secure steam flow to the unit.
3. Secure water flow.
4. Close the condensate drains as required by procedure and/or code.
5. Do not attempt to clean, wipe down or perform any maintenance on the booster until it has been given a generous amount of time to cool down.

Due to the fact that each customer may have different requirements for the orientation of the gas booster heater relative to the main dishmachine, the hose lengths that connect the two units must be customized during each installation. The appropriate 3/4” hosing, fittings and gaskets have been provided.
To prevent incorrect measurements of the hose, it is recommended to place one barbed hose fitting into the end of the uncut length of hose coil and attach that fitting to an appropriate connection. Run the hose to the corresponding connection on the other unit before cutting the hose. Use a barbed hose fitting that is screwed into the second connection on the other unit before cutting the hose. Use a barbed hose fitting that is screwed onto the second connection to gauge the correct distance. Ensure a smooth “flow” of hose without any sharp turns or kinks.
To aid in pushing the barbed hose fitting into the hose, place the fitting on a hard surface (i.e. the floor) with the barbed e nd of the fitting pointing upward and push the hose down onto the fitting. Asmall amount of lubricant (i.e. petroleum jelly) may aid in this process.

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 (ELECTRICALLY-HEATED MODELS): To energize the unit, turn on the power at the service breaker. The volt-
age should have been previously verified as being correct. If not, the voltage will have to be verified. POWER UP (STEAM-HEATED MODELS): 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. Ensure that the steam service is con­nected and that steam is flowing to the machine. Without steam, the water will not reach the required minimum temperatures that the machine is designed to operate at.
POWER UP (GAS-HEATED MODELS): T o 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. Ensure that the gas service is connected and that gas is flowing to the machine. Without gas, the water will not reach the required minimum temperatures that the machine is designed to operate at.
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 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 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 work­day 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 (AJ-66 and AJ-80), operators should also t ake the time to inspect the prewash section strainers and clean them as required by workload.
SHUTDOWN AND CLEANING (ELECTRICALLY-HEATED MODELS): 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 curtains and scrub with a mild detergent and warm water. Wipe out the inside of the unit and then reassemble with the components previously removed.

If the machine has a dataplate like the one shown, which indi­cates both Hot Water Sanitizing and Chemical Sanitizing operation parameters (the area within dashed box), it is pos­sible to change the sanitizing mode after the machine has left the original manufacturer's facility. This change can only be performed by an authorized Jackson service technician. If the machine does not have a dataplate like the one shown, the sanitization mode CAN NOT be changed.
Follow the instructions below to change the mode of sanitiza­tion. Failure to follow these instructions can result in a viola­tion of applicable regulatory codes.
DRIVE MECHANISM MAXIMUM SPEED ADJUSTMENT:
Note: This adjustment is only required when changing from hot water sanitizing to chemical sanitizing mode.
Locate the maximum speed adjustment mechanism at the top of the conveyor drive mechanism (Figure 1). Figure 2 shows an enlarged view of the maximum speed adjustment mecha­nism. Loosen the Bottom Jam Nut approximately one turn counterclockwise. Move the Top Jam Nut down on the threaded shaft by turning it approximately 1/2 turn counter­clockwise. Tighten the Adjustment Nut by turning it clockwise. Retighten the Bottom Jam Nut against the Top Jam Nut.

Please note the parameters for both modes of sanitization. If your data plate has this information, it is convertible from one mode to another.
XXXXXXXXX
THERMOSTAT ADJUSTMENT: Remove the front dress panel from the machine to expose the heater/thermostat box. Remove the cover from the heater/thermostat box. Locate the wash tank regulating thermostat (see diagram).
The wash tank regulating thermostat will maintain the correct wash water temperature. NSF requirements specify that the wash water during operation be 140ºF minimum in the chem­ical sanitizing mode and 160ºF minimum in the hot water san­itizing mode. Adjust the thermostat to achieve the required minimum temperatures during operation. Turn the adjustment screw clockwise to increase the temperature set point, coun­terclockwise to decrease the temperature set point.
Replace heater/thermostat box cover and front dress panel.
IDENTIFICATION OF SANITIZING MODE: Apply the correct temperature gauge label to the face of the temperature gauges. In the chemical sanitizing mode, the temperature gauge labels must specify 140ºF minimum wash temperature and 140ºF minimum rinse temperature. In the hot water san­itizing mode, the temperature gauge labels must specify 160ºF minimum wash temperature and 180ºF minimum rinse temperature.
Apply the correct sanitizing mode label in a visible location on the side of the control box.
INSTALL SANITIZER DISPENSER: For machines in the chemical sanitizing mode, a NSF Standard 29 approved chemical dispenser must be installed to dispense sanitizer into the final rinse line. Follow instructions included with the chemical dispenser. The system selected must be able to pro­vide detergent and sanitizer in the required concentrations.
The minimum chlorine concentration for proper sanitization is 50 PPM. Furthermore, the selected feeder needs to be able to operate against a head of 25 PSI and deliver 7.38 ml of a 10% chlorine sanitizer per minute.
FINAL CHECK: Verify that the incoming water matches the flow pressure and temperature requirements listed on the machine data plate. Verify that minimum wash and rinse tem­peratures are maintained during operation.

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.

Installation Instructions:
1. Wiring: The switch is wired common and nor­mally open because of the hinge design. By interrupting the line in series with the door switches, the dishmachine ceases to operate. Refer to the machine schematic for details on how to wire the switch.
2. Parts of the table switch are mounted in the dishtable, at the end of the table and under the table. See the drawing(s) for the relationship of the switch to the table.
3. Move the limit switch as far down on the two slots as possible and see that the limit switch is straight on the base plate. This might require adjustment of the nut on the connector for the limit switch.
4. Then adjust the inside and the outside con­nector nuts for the connector box so that it lines up even with the limit switch and the base plate.
5. Tighten down the nuts for the seal so that they are tight.
6. If you have any difficulty you might have to adjust the connectors to the seal, screwing in or screwing out until the installation is straight on the table and the limit switch is actuated correctly by the rack.
