SPECIFICATIONS OF THE TEMPSTAR HH GP
VISUAL INSPECTION: Before installing the unit, check the container 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 container. The dishmachine has been inspected and packed at the factory 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 dishmachine 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 circuit.
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 prepunched 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 threading. 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.
INST ALL 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.

Detergent usage and water hardness are two factors that contribute greatly to how efficient 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. 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.
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 automatically 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 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 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 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
“PREP ARATION” 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 recommended to run the machine through 3 cycles to ensure that all of
the cold water is out of the system and to verify that the unit is
operating correctly. To cycle the machine, ensure that the power
is on and that the tub has filled to the correct level. Lift the doors
and the cycle light will illuminate. When the light goes out, close
the doors, the unit will start, run through the cycle, and shut off
automatically . Repeat this two more times. The unit should now be
ready to proceed with the washing of ware.
WASHING A RACK OF WARE: To wash a rack, open the doors
completely (being careful for hot water that may drip from the
doors) and slide the rack into the unit. Close the doors and the
unit will start automatically . Once the cycle is completed, 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 caution 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 manifolds. 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.
