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 dam-

age 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 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 Conserver XL/XL2 series is a gravity discharge drain. All piping from the

2” MNPT 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 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 “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 capable of 20±5 PSI “flow” pressure at the recommended temperature indi-

cated on the data plate.

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.

Do not confuse static pressure with flow pressure. Static pressure is the line pressure in a “no flow” condition (all valves and

services are closed). Flow pressure is the pressure in the fill line when the fill valve is opened during the cycle.

It is also recommended that a shock absorber (not supplied with the Conserver XL/XL2 series models) 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.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS

ELECTRICAL INSTRUCTIONS

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 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 & N) to the appropriate termi-

nals 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 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.

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.

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 con-

centration 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 toggle switches on the right side of control box to prime each pump. There are two (2) switches mounted by the

peristaltic-pumps. One will prime the sanitizer pump only, and the second will prime either the detergent or rinse aid pump,

depending upon which way it is depressed.

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 Cam 6 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 Cam 7 on the cam timer.

6. Chlorine based sanitizer 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 Cam 5 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. Always refer to the chemical agent packaging for safe handling

and first-aid instructions.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS

OPERATION INSTRUCTIONS

PREPARATION: Before proceeding with the start-up of the unit, verify the following:

1. The sump strainer is 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.

FILLING THE WASH TUB: For the initial fill, close doors and depress and hold the OFF/ON/FILL rocker switch in the FILL

position for approximately 8 - 10 seconds. Open the doors and verify that the water level is correct. Hereafter, the water level

is controlled by the timer that has been preset at the factory. Verify that the drain stopper is preventing the wash tub water from

pouring out excessively. There may be some slight leakage from the drain hole. Verify that there are no other leaks on the unit

before proceeding any further. 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.

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. Use the following steps to adjust the cam. Turn power off at the machine circuit break-

er. Open the control box cover. Locate the timer fill valve cam (Cam 4 from the timer motor). Locate the spanner wrench taped

to the electrical panel. The spanner wrench is used to adjust the cam.

To increase the water level, open the notch of the adjustable cam. To decrease the water level, close the notch. Care must be

taken that the set point does not extend into the home position of the timer. Do not move the side of the cam that starts the

fill; this will change the sequence of cycle operation. With the door closed turn the power circuit breaker on. Open and close

the door to run a cycle, then check the water level. Adjust as necessary then close the control box cover.

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 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.

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.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS

OPERATION INSTRUCTIONS (CONTINUED)

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 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.

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 pan 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 manifolds. Remove the endcaps and flush the arms with water. Use a brush to clean out the inside of the arms. If the noz-

zles 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.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS

CAM TIMER OPERATION

The Conserver XL Series cam timer is a 1 minute, 30 second, 8-cam timer (cam 8 is a spare) that controls the operation of the

dishmachine. The following is a description of the set points for each cam and the function of each switch.

CAM 1: Cam 1 is a cut cam with a single notch and serves as the cycle/reset control.

FUNCTION: When the machine is in the operation mode the notch is the home position. The machine will remain idle until the

door is opened, then cam 1 moves to the start position and holds until the door is closed. The closing of the door will start the

next cycle. The cam will rotate a complete cycle, and return to the home position and hold.

CAM 2: Cam 2 is a cut cam and provides the wash cycle timing.

FUNCTION: The wash cam works off the normally open contacts of Cam 2. This requires the microswitch be held closed by

the cam. It will close and energize the wash pump 2 seconds after the cycle switch is activated. The pump will operate through

the wash cycle (40 seconds) then shut down for the dwell period (20 seconds). As the cam rotates it energizes the pump for

the rinse cycle (25 seconds). When cam 1 reaches it’s home position it will de-energize cam 2, shutting down the wash pump.

NOTE: The last 6 cams are adjustable. The following instructions will require that the timer position have the cams to

the front and the motor to the left.

CAM 3: Cam 3 is an adjustable cam and controls the drain valve.

FUNCTION: The drain solenoid works off the normally closed contacts of cam 3. When the cycle is initiated, the microswitch

will be held open until it is allowed to drop into the notch of the cam. This energizes the drain solenoid which drains the

machine. After a 12 second delay the cam reverses the microswitch, de-energizing the drain solenoid. This cam may require

adjusting due to varying water pressure. The drain solenoid must remain open long enough to remove whatever water the fill

valve solenoid allows in the machine. This could vary due to the water supply line pressure.

SETTINGS: The right side of cam 3 must be set to pick up the switch arm just before the wash/rinse cycle cam switch drops.

It will hold the drain solenoid open to drain all the water in the tank from the unit during the dwell period. Any adjustment made

to the drain should be made to the left side of cam 3. The cam must be moved back into the wash time until all of the water is

drained from the machine.

CAM 4: Cam 4 is an adjustable cam and controls the fill valve and therefore the amount of water used.

FUNCTION: The fill valve cam works off the normally closed contacts of cam 4. This requires the switch to be held open by the

cam and allowed to drop into the notch to operate the fill valve. This energizes the fill solenoid which opens to start filling the

machine with fresh water. After a 10 second delay, the cam reverses the microswitch, de-energizing the fill solenoid. The fill

cam may require adjustment due to varying water pressure. The fill solenoid must remain open a sufficient length of time to fill

the machine to the correct level.

SETTINGS: The right side of cam 4 must be set to allow the switch arm to drop 2 seconds before the drain solenoid is de-ener-

gized which flushes the detergent residue from the unit. It will hold the fill solenoid open until the cam switch arm is raised. At

that time the fill solenoid is de-energized, shutting off the incoming water. The tub will be filled to the correct level. Any adjust-

ment made to the timing of the fill solenoid should be made with the left side of cam 4. To increase the water level, open the

notch of the cam and for decreasing the level of the notch should be closed.

CAM 5: Cam 5 is an adjustable cam and controls the sanitizer pump.

FUNCTION: The sanitizer pump cam works off the normally closed contacts of cam 5. This requires the switch arm to be held

open by the cam and allowed to drop into the notch to operate the pump. The time that the sanitizer pump will remain ener-

gized must be determined in the field to suit the chemical used and water conditions.

SETTINGS: The left side of cam 5 must be set to allow the switch arm to drop in past the starting point of the fill cam and after

the drain solenoid has closed. The adjustment for sanitizer volume must be made with the right side of the cam. To increase

the volume the notch should be increased or to decrease the amount of sanitizer the notch should be closed slightly in incre-

ments until the correct level is reached.

CAM TIMER OPERATION (CONTINUED)

CAM 6: Cam 6 is an adjustable can and controls the detergent pump.

FUNCTION: The detergent pump cam works off the normally closed contacts of cam 6. This requires the switch arm to be held

open by the cam and allowed to drop into the notch to operate the pump. The time that the detergent pump will remain ener-

gized must be determined in the field to suit the chemical used and water conditions.

SETTINGS: The left side of cam 6 must be set to drop in past the starting point of the wash pump cam. The adjustment for

detergent volume must be made with the right side of the cam. To increase the volume, the notch should be increased or to

decrease the amount of detergent the notch should be closed slightly in increments until the correct level is reached.

CAM 7: Cam 7 is an adjustable cam and controls the rinse aid pump.

FUNCTION: The rinse aid pump cam works off the normally closed contacts of cam 7. This requires the switch arm to be held

open by the cam and allowed to drop into the notch to operate the pump. The time that the rinse aid pump will remain ener-

gized must be determined in the field to suit the chemical used and water conditions.

SETTINGS: The left side of cam 7 must be set to drop in past the starting point of the fill cam and after the drain solenoid has

closed. The adjustment for rinse aid volume must be made with the right side of the cam. To increase the volume the notch

should be increased or to decrease the amount of detergent the notch should be closed slightly in increments until the correct

level is reached.

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 of 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 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.

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.

2. Faulty sanitizer pump motor. If you read 120V at the sanitizer motor terminals during the sanitizer feed cycle, replace the

motor.

Problem: Machine keeps tripping the service breaker.

1. Power supply shorted to ground. Check for loose wires or burned connections.

2. Faulty door switch or detergent safety switch. Check for loose or wet connections at switch and at wire connectors. Bypass

switch to verify that switch is problem; replace if required.

3. Pump impeller jammed. Clear impeller.

4. Wash pump motor faulty. Check motor voltage and amp load. If amp load is over 12 amps, replace the motor.

5. Circuit breaker is too small. Replace with properly sized breaker. Refer to the data plate.

Problem: Machine will not drain.

1. Loose wire connection. Tighten wires to timer drain microswitch.

2. Drain hole/strainer obstructed. Clear obstructions.

3. Not enough time to drain. Adjust fill cam on timer and/or the drain cam.

4. Drain linkage binding. Repair drain parts.

5. Faulty drain microswitch on timer. With power off and the drain cam on the timer in the home position, remove the

WHITE/YELLOW wire from the microswitch.

6. Faulty drain microswitch on timer. Measure the continuity between the ORANGE wire on the microswitch and the tab that

the WHITE/ YELLOW wire is attached onto. If there is no continuity, replace the microswitch.

7. Drain solenoid defective. Check for voltage at solenoid valve during the drain cycle. Replace if voltage is present.

Problem: Sanitizer pump runs continuously.

1. Shorted sanitizer microswitch on cam timer. If there is not 120V between the ORANGE and GREY wires on the sanitiza-

tion pump motor microswitch when switch is out of the home position, replace the switch.

2. Shorted prime switch. If there is not 120 volts between GREY and WHITE/RED wires to prime switch, replace the switch.

Sanitizer pump does not run during the cycle, but runs when primed.

3. Loose or broken wire. Tighten connections to microswitch.

4. Faulty sanitizer microswitch on cam timer. When sanitizer cam is in home position, measure voltage between ORANGE

and GREY wires on the microswitch. If 120V, replace switch.
