NOTE: THE INSTRCUTION PROVIDED HEREIN, UNLESS
OTHERWISE SPECIFIED ARE FOR THE PHYSICAL DISHMACHINE ONLY. THERE ARE SEPERATE DIRECTIONS FOR THE
GAS BOOSTER.
VISUAL INSPECTION: Before installing the unit, check the con-
tainer 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 throroughly 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 models covered in this manual are gravity disharge drains. 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 30 gallons per minute.
WATER SUPPLY CONNECTION: Ensure that you have read the
section entitled “PLUMBING THE DISHMACHINE” above before
proceding. 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 25 PSI “flow” pressure at
the recommended temperature indicated on the data plate.
In areas where the water pressure fluctuates or is greater than the
recommended pressure, it is suggested that a water pressure regulator be installed. The models covered in this manual do not
come with water pressure regulators as standard equipment.
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. Install
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, and L3 (3 phase only)) 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 antioxidation 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.
VENTILATION OF DISHMACHINE: The dishmachine should be
located with provisions for venting into an adequate exhaust hood
or ventilation system. This is essential to permit efficient removal
of the condensation exhaust. Ensure that the exhaust system is
acceptable in accordance with all applicable codes and standards.
INSTALLATION INSTRUCTIONS

NOTE: Damage caused by steam or moisture due to improper ventilation is NOT covered under the warranty.
This units covered in this manual have the following exhaust
requirements:
Load End: 200 CFM
Unload End: 400 CFM
The exhaust system must be sized to handle this volume for the
dishmachine to operate as it was designed to.
THERMOSTATS: The thermostats for the machines covered in
this manual are factory set. They should not be adjusted except by
an authorized service agent.
DETERGENT: Detergent may be introduced into the unit through
the removal of the bulkhead plug in the rear of the tub and replacing it with the third party detergent injection fitting. Remove the
bulkhead plug in the side of the tub to install the detergent concentration probe.
For more information concerning detergent concerns, please refer
to the page entitled “Detergent Control”.
The 1/8” brass plugs on the incoming plumbing rinse injector may
be removed to install sanitizer and rinse aid injection fittings.
All wires for the chemical injectors should be routed through the
back of the control box.
T erminals in the control box marked “CVS” provide a constant voltage signal whenever the drive motor is operating.
Terminals in the control box marked “DET” provide a voltage signal whenever the wash motor is operating.
DELIMING OPERATIONS: In order to maintain the dishmachine
at its optimum performance level, it will be required to remove lime
and corrosion deposits on a frequent basis. A deliming solution
should be available from your detergent supplier. Read and follow
all instructions on the label of the deliming solution.
To proceed with the deliming operation, fill the dishmachine and
add the correct amount of deliming solution as recommended by
the deliming solution manufacturer. The water capacity of the various tanks of the dishmachine can be verified on the specification
sheet(s) of this manual.
Perform the following operations to delime the dishmachine:
1. Turn the NORMAL/DELIME switch on the back of the control
box to the DELIME position.
2. Disconnect or turn off all chemical feeder pumps.
3. Close all doors (after adding the deliming solution).
4. Run the machine for the recommended period of time.
5. Turn the unit off and open the doors.
6. Wait five minutes, then inspect the inside of the machine. If the
machine is not delimed, run another time cycle as per the deliming solution’s instructions.
7. When clean, drain and re-fill the machine.
8. Run in MANUAL for 10 minutes to remove residual deliming
solution.
9. Drain and re-fill the machine.
INSTALLATION INSTRUCTIONS (CONTINUED)

Due to the fact that each customer may have different requirements for the orientation of the gas booster heater relative to the main
dishmachine, the hose lengths that connect the two units must be customized during each installation. The appropriate 3/4” hosing, fittings and gaskets have been provided.
To prevent incorrect measurements of the hose, it is recommended to place one barbed hose fitting into the end of the uncut length of
hose coil and attach that fitting to an appropriate connection. Run the hose to the corresponding connection on the other unit before
cutting the hose. Use a barbed hose fitting that is screwed into the second connection on the other unit before cutting the hose. Use a
barbed hose fitting that is screwed onto the second connection to gauge the correct distance. Ensure a smooth “flow” of hose without
any sharp turns or kinks.
To aid in pushing the barbed hose fitting into the hose, place the fitting on a hard surface (i.e. the floor) with the barbed end of the fitting pointing upward and push the hose down onto the fitting. A small amount of lubricant (i.e. petroleum jelly) may aid in this process.

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 occurences 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 accomodate 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 distibutor and water treatment specialist
before there is a problem.
