INSTALLATION INSTRUCTIONS
Jackson WWS Inc. provides technical support for all of the dishmachines detailed in this manual and recommends that service
personnel have this manual on hand when calling technical support staff. 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 unit check container and machine for damage. A damaged container may be an indication of damage to the machine. If there is any type of damage to both container and unit, do not throw away the
container. The dishmachine has been inspected at the factory prior to shipping and is expected to arrive in new, undamaged
condition. However, rough handling by carriers or others may result in damage to the unit while it is in transit. If such a
situation occurs, do not return the unit to the manufacturer. Instead, contact the carrier and ask them to send a representative
to the site to inspect the damage, and request that an inspection report be completed.
Contact the carrier within 48 hours of receiving the machine (to report possible freight damage) and the dealer from whom the
unit was purchased.
UNPACKING THE DISHMACHINE: Note: Be careful when cutting the hold down strap (Fig. 3), it is under tension. Remove
the hood (Fig. 4) and set to the side. Please note (Fig. 5) for the location of the O-ring. Once the machine has been removed
from the container, ensure that there are no missing parts (Fig. 5 & 6) 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
8
SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
INSTALLATION INSTRUCTIONS
the top of the tub is level from side to side and from front to back before making any connections.
INSTALLING THE DISHMACHINE: With the machine base set in place,
lift the table (Fig. 7) (with proper flange cutout) over and above machine
so that vertical flange on table cutout fits down inside of machine tub and
horizontal flange on machine tub fits up tight against underside of the
table.
(Fig. 7)
INSTALLING THE VACUUM BREAKER & PLUMBING: Ease vacuum
breaker piping (Fig. 8) supplied with the dishmachine down through the
square cutout in the backsplash of the table (directly behind the
machine). Connect vacuum breaker piping to machine. The top union connects to its matching half on the bottom of the rinse
booster tank (Fig.9). The bottom union of the piping connects to an adapter pipe which, in turn connects to the solenoid valve
(Fig. 10). The arrows on the solenoid valve indicate the direction
of water flow to the machine. Tighten both of the connections.

ALIGNING THE MACHINE: Adjust the machine base to line up hole in table with hole in sup-
port block (Fig. 11).
(Fig. 11)
INSTALLING THE INTERNAL VACUUM BREAKER: Insert internal vacuum breaker pipe into hood support block pin end down (Fig.12).
WARNING: Internal vacuum breaker pipe must be installed or
there will be a hazard to the operator.
(Fig. 12)
INSTALLING THE HOOD ASSEMBLY: Make sure there are two “Orings” (Fig. 5) on the lower support pipe near the end of the ring. While
also holding the internal vacuum breaker, lift the hood and hood support pipe up over table. Set hood support pipe down into the support
block hole (Fig. 13) and begin to work the hex nut into the hole. The
locating pin in the support block will insure proper line up. While holding the support pipe, start tightening nut by hand to prevent cross
threading. It should tighten considerable by hand. Then continue tightening with a wrench. It may be necessary to work support pipe back
and forth to seat nut properly. When the nut is tight, it should force flat
the stainless steel and rubber washers tight to the table top.
(Fig. 13)
Attach vacuum breaker support pipe clamp (Fig. 14) to the support pipe
and external vacuum breaker piping. Slide up about 12” from the table
and tighten securely. Position cover plate (supplied with table) over
square cutout in backsplash on table so that it fits tightly around piping
then snap in the four nylon fasteners (supplied) to hold in place.
Rotate the hood to insure it is free, if not, check level of machine, tightness of table to machine flange, centering of machine, level of table and
hood support pipe.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
INSTALLATION INSTRUCTIONS
PLUMBING THE DISHMACHINE: All plumbing connections must comply with all applicable local, state, and national plumb-
ing 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 dishmachine is a gravity discharge drain. Remove the overflow strainer
stopper from the tub and the unit will drain itself. 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 end of the Y-strainer. 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 Model 10 does not come with water a pressure regulator 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 with the dishmachine) 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.
Refer to the data plate for machine operating requirements, machine voltage, total amperage load and serial number.
To install the incoming power lines, first remove the lower control box cover (Fig. 15). Next, run the power lines through the
hole located in the bottom of the control box to the terminal board inside (Fig. 16). This board is accessible by removing the
lower cover plate on the control box. Attach lines (L1 and L2 (L3 for three phase)) on the terminal block at the lower front right
corner. There is no neutral wire on this machine. There is a grounding lug inside the control box on the bottom left. Be sure all
connections made are tightened properly. 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 lower
cover and tighten down the screws.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
OPERATION INSTRUCTIONS
PREPARATION:
1. Ensure that the pump intake strainer (1) and basket overflow strainer (2) are
inserted and tight.
2. Ensure that the wash and rinse arms are installed and secure.
3. Remove all solid wastes in order to avoid obstructing filters, drain and wash and
rinse arms.
4. Ware that is encrusted with soil should be presoaked prior to being placed in the
machine.
5. When placing dishes into the racks, do not allow them to lean on each other.
6. Place the glasses upside down in the open rack. With the model 10 series, a four
compartment silverware rack is supplied. Place silver in compartment rack loosely
not allowing it to mix with other silverware of the same nature. Place the compartment rack in the open rack and wash with the cups and glasses.
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 CYCLE: At the beginning of each work day, a warm up cycle will need to be performed. Close the hood (3). Turn
on the master switch (4). Raise the fill switch (5) until the machine is filled to the top of the basket overflow strainer (2.) Once
the proper water level has been reached, turn on the heater switch (6). Observe the temperature gauges, the rinse temperature should rise to a specified level of 180°F within five minutes if the incoming water to the booster tank is 140°F. The wash
heater will take longer to reach 150°F as the element is designed for maintaining temperature, not heating. Once the proper
temperature has been reached, with the hood closed, turn on the manual wash switch. You should hear the water being
pumped as it strikes the top of the hood. Turn off the manual wash switch. The dishmachine is now ready to proceed with washing of the dishes.
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 throwing unscraped dishes into the machine will defeat 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 good ideas,
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.
WASHING A RACK OF WARE: To wash a rack, open the hood completely (being careful for hot water that may drip from the
top of the hood), manually load detergent into the wash chamber, or if automatic detergent dispenser is used, follow the manufacturers instructions. Slide the rack of dishes into the dishmachine. Close the hood. Start the automatic wash and rinse cycle
of the dishmachine by flipping the start switch (7) either up or down (NOTE: The start switch, is a three position switch. Up =
Start, Center = Off, Down = Start) the indicating light (8) will come on at the start of the cycle. When the light goes off, the cycle
is complete. Open the hood, remove the rack of clean dishes to air dry. Repeat the cycle by adding another rack of soiled dishes, adding the detergent, close hood and flip start switch (8) in opposite direction.
SHUT DOWN AND CLEANING: At the end of meal time, shut off the dishmachine by placing the start switch in center position and turn heat switch off. Drain the dishmachine by removing the overflow strainer. Remove the pump intake strainer after
water has drained. Clean both strainers. Clean the inside of the unit. Clean wash head, upper and lower rinse arms and replace
the clean strainers. Replace all removed parts. The machine is now ready for refilling and operation.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
DETERGENT CONTROL
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.
