VISUAL INSPECTION: Before installing the unit, check the container and machine for damage. A damaged container is an indicator 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, undamaged
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 missing
parts from the machine. This may not be obvious at first. If it is discovered that an item is missing, contact Jackson immediately to
have the missing item shipped to you.
LEVEL THE DISHMACHINE: The dishmachine is designed to
operate while being level. This is important to prevent any damage to the machine during operation and to ensure the best
results when washing ware. The unit comes with adjustable bullet
feet, which can be turned using a pair of channel locks or by hand
if the unit can be raised safely. Ensure that the unit is level from
side to side and from front to back before making any connections.
PLUMBING THE DISHMACHINE: All plumbing connections must
comply with all applicable local, state, and national plumbing
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 Tempstar GP
is a gravity discharge drain. All piping from the 1 1/2” FNPT 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 1 1/2” I.P.S. 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 PSI “flow” pressure at the recommended temperature indicated on the data plate.
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 Tempstar GP model) be installed in the incoming water line.
This prevents line hammer (hydraulic shock), induced by the solenoid valve as it operates, from causing damage to the equipment.
PLUMBING CHECK: Slowly turn on the water supply to the
machine after the incoming fill line and the drain line have been
installed. Check for any leaks and repair as required. All leaks
must be repaired prior to placing the machine in operation.
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 &L2) to the appropriate terminals 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 incoming
power at the terminal block and ensure it corresponds to the voltage listed on the data plate. If not, contact a qualified service
agency to examine the problem. 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 proper personnel
of any problems and of the location of the service breaker.
Replace the control box cover and tighten down 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.
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.
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. 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
4
PREPARATION: Before proceeding with the start-up of the unit,
verify the following:
1. The pump intake, and wash tank strainers are 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:Ensure that the delime switch is in the
NORMAL position, and place the power switch into the ON position. The Tempstar GP should fill automatically and shut off when
the appropriate level is reached (just below the wash tank strainer). Verify that the drain stopper is preventing the wash tub water
from pouring out excessively. There will probably 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 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 breaker. 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.
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 recommended, 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, 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.
OPERA TIONAL INSPECTION: Based upon usage, the wash tank
strainer may become clogged with soil and debris as the workday
progresses. Operators should regularly inspect the wash tank
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 wash tank 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 wash tank 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 nozzles 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.
