our staff can refer you, if necessary, to the proper page. Technical
support is available from 8:00 a.m. to 5:00 p.m. (EST), Monday
through Friday. Technical support is not available on holidays.
Contact technical support toll free at 1-888-800-5672. Please
remember that technical support is available for service personnel only.
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 is a gravity discharge drain. All piping from the 1 1/2” FNPT connection on the
wash tank 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” 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) 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 four
(4) screws 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, & L3 (three phase)) to the appropriate
terminals as they are marked on the terminal block. Install the
grounding wire into the lug provided. Tighten the connections. 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
2
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.
FILLING THE WASH TUB: For the initial fill, ensure that the cycle
selection switch is in the “AUTO” (automatic) position, and place
the power switch in the “ON” position. The unit will fill automatically and run through a rinse cycle. Open the doors and verify that
the water level is correct. Hereafter, the water level is controlled by
the overflow tube. Verify that the drain stopper is preventing the
wash tub water from draining 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.
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.
WATER CONSUMPTION ISSUES AND EFFICIENCY: The
Tempstar HH 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 dishmachine operates
at peak efficiency for your needs. Water hardness and detergent
usage will also effect the results of the dishmachine.
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 operates at peak performance!

The Tempstar models covered in this manual come supplied with various heaters, depending on the characteristics of the machine.
To ensure that you order the correct heater for the model you are servicing, please refer to the following table:
This unit has a probe-direct sensing type thermostat with fixed set point and adjustable range for both wash and booster tank heat regulating. The same type thermostat is used as the high limit sensor for the wash tank heater. It operates a precision single double throw
switch through a lever for close tolerance narrow differential switching capability. The unit has screw driver adjustment and front connect terminals and is mounted by 7/16”-24 thread, Loxit fitting for easy removability and serviceability. The thermostat range is from
140°Fto 240°Fwith a maximum bulb exposure temperature of 300
°F
. Unit is listed at 12.5 amps at 24/120 VAC.
There are three (3) thermostats on the dishwasher. One monitors the wash tank temperature, the second monitors the rinse water temperature with the third protecting the heater element. Although all are identical in appearance there are different replacement part numbers depending on the function of the thermostat.
Calibration:
The hi-limit thermostat is used to protect the heater element in the event of a run away regulating thermostat or a dry fire situation. It
is set for 210
°F
+0 or -10
°F
with a fixed set point. This part is not adjustable.
The wash tank regulating thermostat will maintain the correct wash
water temperature to meet NSF requirements. These specify that the
wash be no lower than 150
°F
. It is set at the factory to energize the
tank heater at 155
°F
and de-energize at 167°F.
The rinse tank regulating thermostat will maintain the correct rinse
water temperature to meet NSF requirements. It is factory set to energize the rinse tank heater at 195
°F
and de-energize at 200°F.
To order the thermostats:
Thermostat, High Limit 5930-121-71-36
Thermostat, Wash Tank 5930-121-67-72
Thermostat, Rinse Tank 5930-121-71-29
The models covered in this manual come supplied with various wash motor assemblies (a wash motor assembly includes the wash
motor and the pump end), depending on the characteristics of the machine. To ensure that you order the correct wash motor assembly for the model you are servicing, please refer to the following table:

Important note: When servicing a wash motor,
it is important to refer to the wiring schematic
found on the motor, to ensure that the motor is
wired correctly. Different manufacturers of
motors may not use the same wire color codes
and therefore, your new motor, which may have
been built by someone different than who built
your original motor, may not connect using the
same wires. Always refer to the wiring diagrams
on the motor you are installing. If the motor you
are installing has had the schematic removed,
contact Jackson MSC immediately for technical
support.

When servicing plumbing components, take care not to damage the threads of each individual item. Damaged threads can cause leaks
and loss of pressure, which could adversely effect the performance of the dishmachine. It is strongly recommended that teflon thread
tape, used in conservative amounts, be applied to threads when joining components together. It is not advised to use thread sealing
compounds, sometimes referred to as “pipe dope”. Compounds can be ejected from the threads during the tightening process and
become lodged in key components, thereby rendering them useless. Some of the components include the solenoid valve and the pressure gauge isolation ball valve.
