SPECIFICATIONS OF THE TEMPSTAR HH GP

VISUAL INSPECTION: Before installing the unit, check the con-

tainer and the machine for any damage. A damaged container

could be an indication of damage to the unit. If there is damage to

both the container and the unit, DO NOT throw away the contain-

er. The dishmachine has been inspected and packed at the facto-

ry with the expectation that it will arrive to you in new, undamaged

condition. However, rough handling by carriers or others may

damage the unit while in transit. If this situation does occur, do not

return the unit to Jackson; instead contact the carrier and ask

them 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 you purchased the

machine through.

UNPACKING THE DISHMACHINE: Remove the machine from

the container and inspect for any missing parts. If an item appears

to be missing, contact Jackson immediately to report it.

LEVEL THE DISHMACHINE: The dishmachine(s) covered in this

manual are designed to operate on a level surface. Ensure that

the machine is level from side to side and from front to back;

adjust the unit’s bullet feet as required. Failure to level the dish-

machine may cause decreased washing performance.

PLUMBING THE DISHMACHINE: All plumbing connections must

comply with all applicable local, state and national plumbing

codes. The plumber is responsible for flushing the incoming water

line prior to connecting it to remove all foreign debris that may get

trapped in the valves or cause an obstruction. Any valves that are

fouled by matter left in the water line and the expenses resulting

are not the responsibility of the manufacturer.

CONNECTING THE DRAIN LINE: The Tempstar HH GP drain

requires a minimum 1-1/2” IPS piping that is pitched at least 1/4”

per foot. 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: Install the water supply line

(3/4” IPS minimum) to the dishmachine line strainer using copper

pipe. It is recommended that a water shut-off valve be installed

between the main supply and the machine to allow for service.

The water supply line must be capable of 20 PSI “flow” pressure

at the recommended temperature as indicated on the data plate.

It is also recommended that a shock absorber (not supplied with

the Tempstar HH GP) be installed in the incoming water line. This

prevents line hammer (hydraulic shock), induced by the solenoid

valve, which can cause damage to the equipment.

PLUMBING CHECK: Slowly turn on the water supply to the

machine after connecting the incoming fill line and drain line.

Check for leaks and repair as required. Leaks must be repaired

prior to placing the machine in operation.

ELECTRICAL POWER CONNECTION: Electrical and grounding

connections must comply with all applicable portions of the

National Electric Code (ANSI/NFPA 70) and/or other electrical

codes that may apply.

Disconnect the electrical power supply and place a safety tag at

the disconnect switch to indicate that you are working on the cir-

cuit.

The dishmachine data plate is located on the left front corner of

the machine. Refer to this data plate for information concerning

the unit’s specific electrical requirements.

To install the incoming power lines, open the connection box by

removing the connection box lid. Install 1/2” coduit into the pre-

punched holes in the back of the connection box. Route the power

wires and connect to the power block and grounding lug. Install

the service wires (L1 and N) to the appropriate terminals as they

are marked on the terminal block. Install the grounding wire into

the lug provided. Wires should be firmly secured in place.

It is recommended that “De-Ox” or another similar anti-oxidation

agent be used on all voltage connections.

VOLTAGE CHECK: Ensure that the machine is off and apply

power to the machine. Check the incoming power at the terminal

block and ensure it corresponds to the voltage on the machine

data plate. Do not run the dishmachine if the voltage is too high or

too low. Shut off the service breaker and mark it as being for the

dishmachine. Advise all personnel of the location of the service

breaker. Replace all covers and tighten the screws.

INSTALLATION INSTRUCTIONS

It is very important that the type and inlet pressure of the gas used corresponds to the machine data plate. This machine is equipped

with a 1/2” female line for connection of gas. The gas line used should be of the type approved for use with natural gas or propane,

depending on the gas selected to be used in this machine. The gas line should be sized to carry the maximum flow of 55,000 BTUs.

Too small of a gas line will result in poor performance. A manual gas shut-off valve must be installed in the gas line, located within an

accessible area of the machine. The gas line should be kept as short as possible and installed in a way to protect it from damage.

When making pipe connections, use an AGA approved pipe dope, being careful not to use excessive amounts as to foul the gas valve

or clog the gas line. When tightening the gas line always support the gas valve to avoid damage to the gas train.

Note: In propane installations, the gas must be supplied from a regulated source.

When making the connection to the booster unit, take care to start the gas line fitting by hand and tighten by hand to avoid cross thread-

ing. Tighten fitting with a wrench, taking care not to damage any internal components of the unit.

After making a final connection of gas, with power to the unit turned off, check all gas line fittings for leaks, using a liquid test solution,

and an approved leak detector.

WARNING

ENSURE THAT THERE IS NO ELECTRICAL POWER APPLIED TO THE MACHINE WHEN MAKING GAS CONNECTION.

CHECK ALL GAS CONNECTIONS FOR LEAKS PRIOR TO APPLYING POWER.

THE GASES USED FOR COMBUSTION IN THIS DISH MACHINE ARE HIGHLY FLAMMABLE.

DO NOT SMOKE AROUND THIS MACHINE.

ENSURE THAT THE AREA WHERE THIS MACHINE IS TO BE INSTALLED IS WELL-VENTILATED TO PREVENT THE BUILD-UP

OF COMBUSTIBLE GASES.

ENSURE THAT ALL LOCAL HEALTH, FIRE, AND BUILDING CODES ARE BEING ADHERED TO WHEN INSTALLING THIS

MACHINE. VERIFY WITH LOCAL OFFICIALS IF THERE ARE ANY QUESTIONS.

INSTALL A SHUT-OFF VALVE AT THE GAS SOURCE AND SUPPLY THE MACHINE USING A 1/2” LINE. CONNECT TO THE 1/2”

NPT FITTING ON THE MACHINE.

GAS CONNECTION

Detergent usage and water hardness are two factors that contribute greatly to how efficient your dishmachine will operate. Using deter-

gent 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 talk-

ing about.

First, you must understand that hard water greatly effects the performance of the dishmachine. Water hardness is the amount of dis-

solved 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 dish-

es. 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 deposit-

ed 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 dry-

ing 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 train-

ing 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 deter-

gents 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 locat-

ed 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 dish-

machine operators to observe the required temperatures and to report when they fall below the minimum allowed. A loss of tempera-

ture 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 special-

ist before there is a problem.

DETERGENT CONTROL

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

verify the following:

1. The pan strainer and pump suction strainer are in

place and are clean.

2. The overflow tube and o-ring are 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 in the ON position.

The Tempstar HH GP should fill automatically and shut off when

the appropriate level is reached (the gas burners should also auto-

matically ignite as well). The appropriate water level si just below

the tub strainer. The wash tank must be completely filled prior to

operation of the wash pump to prevent damage to the pump and

motor.

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 dishma-

chine will be reduced. It is important to remember that a dishma-

chine 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 required, 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 dish-

machine 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.

WARM-UP CYCLES: For a typical daily start-up, it is recom-

mended 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, the cycle

light will turn off, 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. Remove and clean

the pan strainer. Remove the drain stopper from the tub and allow

the tub to drain (NOTE: The wash tank water will be hot so cau-

tion is advised). Once the wash tub is drained, remove 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, 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 drain stopper and strainers and close the doors.

OPERATION INSTRUCTIONS

ATER CONSUMPTION ISSUES AND EFFICIENCY

The Tempstar HH GP provides you, the customer, with the ability to control the hourly rack capacity of the machine. Extending the wash

cycle to wash severely soiled ware, such as mixing bowls, does not increase the machine’s water consumption. However, selecting a

longer time cycle does lower the amount of dishes the machine will be able to wash per hour. It is important for operators to select the

correct wash cycle depending on the amount of washing required. Not every rack of dishes requires the machine to be set on the

longest wash cycle!

Using good prescrapping procedures and observing the results of individual racks of ware, operators will soon gain the experience and

knowledge required to ensure that the Tempstar HH GP operates at peak efficiency for your needs.

Water hardness and detergent usage will also effect the results of the Tempstar HH GP. This manual provides a page on detergent con-

trol. It is recommended that owners and operators take the time to carefully review this section in order to ensure that everything is

done to make sure the Tempstar HH GP operates at peak performance!

WATER CONSUMPTION ISSUES

The Tempstar HH GP heating system is designed to heat and maintain the wash tank water temperature at a minimum of 150

F as well as providing a constant 180 F rinse water temperature. Incoming water is supplied at a pressure of 20psi and between 110-

140 F. Incoming gas pressure should be between 7.0-10.5 WCI for natural gas, or 11.0-14.0 WCI for units supplied with propane. The

sequence of operation is as follows (please refer to the above diagram):

When the power is turned on at the ON/OFF switch the water level control board will sense a low water level in the wash tank

and the unit will begin to fill. This occurs as the rinse solenoid valve opens, allowing connected water to fill the booster tank, heat

exchanger and the rest of recirculating system, once the booster tank is full, water will fill the wash tank until the water level control sys-

tem is satisfied. Simultaneously with the fill, the rinse recirculating pump and the gas burner assembly are energized, this will begin

heat up of the unit. A transformer in the main control box supplies +12vdc to the electronics control drawer located in the lower section

of the unit. The electronics control board (ECB) is the brain of the system. The ECB receives various inputs and determines the amount

of heating required.

When energized the ECB receives input from the T-mid thermistor indicating a low water temperature in the recirculating sys-

tem. The ECB will power the ignition relay on the board, which in turn provides +12vdc to the direct spark ignition board (DSI). The DSI

sends +12vdc to the combination gas cutoff valve to open it. This will supply gas to the burner assembly. The DSI begins sparking the

igniter probe, and monitors the flames presence. If the flame is not sensed during the ignition attempt, then the DSI will lockout until

the software resets the DSI approximately 60 seconds later.

The operator may turn the power off at the ON/OFF switch for approximately 5 seconds, and then back on. This will also reset

the ECB and the DSI. If flame is lost during normal burn, the DSI will attempt a reignition.

The ECB monitors the 12vdc signal from the DSI to the combination gas cutoff valve. The software in the ECB also reads the

temperature at the middle of the heat exchanger with the T-mid thermistor. After the 5.5 second ignition time, the software will increase

gas flow to the burner to minimum burn by increasing voltage to the modulating valve (MV). If the heat exchanger temperature is far

away from the stabilization temperature, the software will increase gas flow to maximum burn.

Once the heat exchanger temperature nears the stabilization temperature the gas flow is slowly reduced until the minimum

burn is attained. The software will keep the unit in minimum burn until the heat exchanger temperature exceeds stabilization tempera-

ture and then the gas will be shut off. Over many minutes, the software will turn the burner off and on repeatedly until all the water in

the system reaches the stabilization temperature. At this point the software will only turn the burner on every 1-2 minutes to maintain

the stabilization temperature. Now the unit is ready for operation.

As the dishwasher rinses with hot water from the booster tank, it is replaced with cooler water. The need to heat the new water

is sensed by the software and the burner is turned on. The software will modulate the gas flow between minimum and maximum gas

flow attempting to recover the stabilization temperature and always keeping the tank temperature above the required temperature.

The stabilization temperature may be adjusted by means of a potentiometer located on the ECB. This is referred to as the T-

set. (normally 4.25vdc)

The recirculating pump draws water from the rinse booster tank and circulates it through the wash tank coils where it will heat

the water residing in the wash tank. The water then returns to the heat exchanger where it is reheated. This hot water then flows back

to the rinse booster tank and repeats the cycle.

The thermostat,(in conjunction with the wash temp relay) is used during idle times to prevent wash tank temperature from

exceeding 170° F, during normal operation the wash tank will self regulate between 150-165°. However, when idle, the temperature in

the wash tank will slowly rise towards booster tank temperature until the temperature reaches 170° F. The wash tank thermostat will

cycle the heat exchanger & recirculating pump off. When the wash tank temperature lowers, the heat exchanger and recirculating pump

will energize. This will continue during all idle time. At any time that the unit is placed into operation, the wash

temp relay will energize and immediately power the heat exchanger and the recirculating pump, regardless of the thermostats position.

Excessive high temperatures in the system are avoided by the following: 1. High temperature limit control by input from T-mid

thermistor, 2. energy cutoff temperature lockout (ECO) by means of a bi-metallic switch independent of the microprocessor which will

break voltage to the combination gas cutoff valve if temperature in the system exceeds 210 F.

Excessive high pressures that potentially could be created in the system are vented directly to atmosphere by means of the

rinse booster tank and rinse arms.

OVERVIEW OF OPERATION (CONTINUED)

THERMOSTAT ADJUSTMENT PROCEDURE

1) Start up unit

2) Allow to fill, and start warm-up

3) Turn thermostat trim screw counter-clockwise (CCW) 2 full revolutions

4) Allow wash temperature to reach 170"F on wash temperature gauge

5) Turn thermostat trim screw clockwise (CW) until flashing green LED on control board turns off. (The recirculating pump

will also turn off).

6) To ensure that the trim screw has not been turned too far CW, turn CCW very slowly until green LED turns on and once

again turn CW very slowly until green LED goes out.

7) Start normal operation and monitor wash tank temperature.

8) If readjustment is needed repeat steps 5 - 7 until wash tank temperature maintains at 170"F during idle time.

AUTO-CALIBRATION PROCEDURE

Figure 1 Figure 2

Note: This procedure must be completed every time you replace either a control board or a modulating valve.

1. Turn the unit off at the main power switch and let stand for one minute.

2. Remove the lower front panel and set aside.

3. Remove the cover of the rectangular control box.

4. Locate the control board (see Figure 1).

5. Locate and remove the jumper labeled ACAL (see Figure 1) from the control board. Be careful to remove the metal jumper and not

just the plastic insulator. Make a note of the exact position that the jumper was located. Set the jumper aside for later re-installation.

6. With your multimeter set on DC volts, attach to the Molex plug going to the modulating valve. Note: do not disconnect the Molex

plug. Insert the probes in the rear of one side so contact is made with the metal pins inside of the plug (see Figure 2).

7. Turn the machine on. The burner will ignite and run through a series of steps. Watch the readings of your multimeter. They will run

approximately 11.9 VDC at the highest flame; step down to about 6.0 VDC and then step down again slightly to 5.7 or 5.8 VDC before

shutting the burner off. This whole process takes about 1 - 2 minutes.

8. Once the burner goes out, turn the dishmachine off.

9. Wait one minute.

10. Replace the jumper on the control board in the exact same position as it was removed.

11. Turn the dishmachine back on.

12. Check for normal operation.

ELECTRONICS CONTROL BOARD (ECB)

The control board regulates the temperature of the water in the heat exchanger system. This water is also used as the rinse water for

the rinse cycle of the dishwasher. It does this by regulating the flame of the burner by increasing or decreasing the voltage to the mod-

ulating valve. The modulating valve, in turn, increases or decreases the gas pressure going to the burner manifold depending on the

voltage it is getting from the control board. From time to time it may be necessary to check or adjust the setting of this water tempera-

ture. To test the setting or to reset the temperature of the rinse water, make sure the unit is on and the green LED on the board is flash-

ing steadily. Insert the NEGATIVE (black/common) probe of a multi-meter set on DC volts in the BLACK test point (see above). Insert

the POSITIVE (red) probe of the multi-meter in the BLUE test point. The reading will indicate the set point temperature. The factory

setting is 4.25 VDC which corresponds to 198"F (92"C). Adjustments to the set point are made on the BLUE POTENTIOMETER direct-

ly below the BLUE test point. With a very small slotted screwdriver rotate the trim screw on the potentiometer clockwise (CW) to

increase the voltage (and temperature) and counterclockwise to decrease.

Testing and Setting the Set Point Temperature

TESTING THE THERMISTORS

There are two thermistors that are used in controlling the temperature of the water in the heat exchanger system. The T- in that sam-

ples the temperature of the water going into the heat exchanger and the T-Mid that samples the temperature halfway through the heat

exchanger. The control board constantly monitors the temperature at the T-Mid thermistor and adjusts the burner pressure by way of

the modulating valve according to how far away that temperature is away from the set point temperature.

Thermistors are devices that change their resistance value with changes in temperature. By running a constant voltage through the

thermistor, one can read the change of voltage caused by the change of resistance thus determining the temperature of the thermis-

tor. There are test points on the control board (see above) that can be read with a multi-meter on the direct current volt (DCV) scale for

each thermistor.

o test the temperature at the T-in Thermistor

There is a BLACK test point along the top edge of the control board on the right side of center. This is where the NEGATIVE (com-

mon/black) probe of a multi-meter is inserted. There is an ORANGE test point along the top edge of the control board on the left side

of center. This is where the POSITIVE (red) probe of a multi-meter is inserted. A DC voltage reading is then taken. Find

the voltage on the chart below and find the corresponding temperature.

To test the temperature at the T-Mid Thermistor

Using the same BLACK test point with the NEGATIVE probe of the multi-meters in testing the T-in thermistor above, also find the YEL-

LOW test point on the left side of the board just under the large plug (see above). Insert the positive probe of the multi-meter and read

DC volts. Since the two thermistors have the same values, the same chart is used.

CONTROL BOARD LED LIGHT INDICATIONS

The electronic control board (ECB) has two LED light indicators that can be seen at its upper left hand corner.

The following conditions for each light may be seen during operation of the unit.

1) Green LED is off.

A) Dishmachine is turned off, therefore no power to ECB.

B) Wash thermostat has cycled off, therefore breaking power to 12 volt transformer in the main control box.

This will also disrupt power to the ECB.

C) ECB may have never recieved an AUTO CALIBRATION.

D) ECB may be damaged due to high voltage.

E) Control chip in ECB may be misaligned, not fully inserted, or damaged.

2) Green LED is a illuminated and steady.

A) ECB has been damaged in some form.

3) Green LED is illuminated and flashing.

A) This is the normal operating condition.(whether the LED flashes rapidly, or at a slower rate).

4) Red LED is off.

A) This is the normal operating condition.

5) Red LED is illuminated and steady, or flashing.

A) This is an indication of a malfunction of the T-MID thermistor. Thermister may be unplugged, grounded, have frayed

wiring, or other damage.
