INSTALLATION & OPERATION
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: The machine should be unboxed and removed from the pallet prior to installing. Open
the front door and remove all of the materials from the inside. Once unpacked, verify there are no missing parts. If a part
is missing, contact manufacturer immediately.
LEVEL THE DISHMACHINE: The dishmachine is designed to operate while level. This is
important to prevent any damage to the machine during operation and to ensure the best
results possible. The unit comes equipped with adjustable bullet feet which can be turned
using a pair of pliers. Verify the unit is level from front to back and side to side before making
any electrical or plumbing connections.
Raise
Lower
PLUMBING THE DISHMACHINE: All plumbing connections must be made to adhere to local,
state, territorial and national codes. The installing plumber is responsible for ensuring the in-
Frame with Adjustable Foot
coming water lines are ushed of debris prior to connecting to the machine. Note that chips and
materials from cutting processes can become lodged in the solenoid valves and prevent them from opening or closing. Any
valves that are found to be fouled or defective because of foreign matter left in the water line, and any subsequent water
damage, are not the responsibility of the manufacturer.
A water hardness test must be performed to determine if the HTS-11 (scale prevention & corrosion control) needs to be
installed. A hardness test kit can be found on the warning tag that is attached to
the incoming plumbing connection on
the back of the machine. If water hardness is higher than 5 GPG, the HTS-11 will
need to be installed. Please contact manufacturer to purchase the HTS-11.
CONNECTING THE DRAIN LINE: The dishmachine's 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 oor 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 oor sink or drain. If a grease trap is
required by code, it should have a ow capacity of 5 gallons per minute.
Incoming Plumbing Y-strainer Connection

INSTALLATION & OPERATION
INSTALLATION INSTRUCTIONS
WATER SUPPLY CONNECTION: Read the section entitled “PLUMBING THE DISHMACHINE” before proceeding. Install
the water supply line (3/4” pipe size minimum, 1/2" pipe size minimum for LT) 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 ma-
chine to allow access for service. The water supply line is to be capable of 20±5 PSI “ow” pressure at the recommended
temperature indicated on the data plate. Take care not to confuse static pressure with ow pressure: Static pressure is line
pressure in a “no ow” condition (all valves and services are closed); ow pressure is the pressure in the ll line when the
valve is opened during the cycle. It is suggested that a shock absorber (not supplied) be installed on the incoming water line.
This prevents water 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 ll 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.
STEAM LINE CONNECTION: The steam machines come with lines by which the source steam needs to be connected.
Connect all steam lines to the machine as all applicable codes provide. See machine data plate for information concerning
steam ow pressure.
Ground Lug
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 only)) to the appropriate
terminals as they are marked on the terminal block. Install the grounding wire

INSTALLATION & OPERATION
OPERATING INSTRUCTIONS
PREPARATION: Before proceeding with the start-up of the unit, verify the following:
• The pan strainer and pump suction strainer are clean and in place.
• The overow tube and o-ring are installed.
• The wash and rinse arms are screwed securely into place, rotate freely and that their endcaps are tight.
POWER UP: To energize the unit, turn on the power at the service breaker. The voltage should have been previously
veried as being correct. If not, the voltage must be veried before proceeding.
FILLING THE WASH TUB: For the initial ll, ensure that the cycle selection switch is in the “AUTO” (automatic) position, and
place the power switch in the “ON” position. The unit will ll automatically and run through a rinse cycle. Open the door and
verify that the water level is correct. Hereafter, the water level is controlled by the overow 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 lled before operating
the wash pump to prevent damage to the component. Once the wash tub is lled, the unit is ready for operation.
WARE PREPARATION: Proper preparation of ware is essential for the smooth, efcient operation of your dishmachine.
If done properly, you can expect to have fewer re-washes and use substantially less detergent. Any ware placed inside
the machine should have all solid food waste and scraps removed. 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. Load plates and saucers in the same direction, with the food surface facing the unload end of the machine.
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 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 the tub has lled to the correct level. Lift the door and the cycle light will illuminate. When the light goes
out, close the door. The unit will start, run through a cycle and shut off automatically. Repeat this two more times. The unit
is now ready to proceed with the washing of ware.
WASHING A RACK OF WARE: To wash a rack, open the door completely (beware of hot water dripping from the door)
and slide the rack into the unit. Close the door and the unit will start automatically. Once the cycle is completed, open the
door (again careful of the dripping hot water) and remove the rack of clean ware. Replace with a rack of soiled ware and
close the door. 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 becomes clogged, 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.

INSTALLATION & OPERATION
OPERATING INSTRUCTIONS
STEAM FLOW: Secure steam ow to the machine in accordance with applicable codes and procedures. Steam ow must
be secured prior to cleaning the inside of the machine.
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 door. 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. Dispose of any soil and debris found in the strainer. Unscrew the wash and
rinse arms from their manifolds. Remove the endcaps and ush 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 door.
WATER CONSUMPTION ISSUES AND EFFICIENCY: The models covered in this manual provide 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.

INSTALLATION & OPERATION
DETERGENT CONTROL
DETERGENT CONTROL: Detergent usage and water hardness are two factors that contribute greatly to how efciently
this dishmachine will operate. Using detergent in the proper amount can become a source of substantial savings. A
qualied water treatment specialist can relate what is needed for maximum efciency from the detergent.
1. Hard water greatly affects the performance of the dishmachine, causing the amount of detergent required for washing
to increase. If the machine is installed in an area with hard water, the manufacturer recommends the installation of water
treatment equipment.
2. Deposited solids from hard water can cause spotting that will not be removed with a drying agent. Treated water will
reduce this occurence.
3. Treated water may not be suitable for use in other areas of operation and it may be necessary to install a water
treatment unit for the water going to the dishmachine only. Discuss this option with a qualied water treatment specialist.
4. Dishmachine operators should be properly trained in how much detergent is to be used per cycle. Meet with a water
treatment specialist and detergent vendor to discuss a complete training program for operators.
5. Certain dishmachine models require that chemicals be provided for proper operation and sanitization. Some models
may require the installation of third-party chemical feeders to introduce those chemicals to the machine. The manufacturer
does not recommend or endorse any brand name of chemicals or chemical dispensing
equipment. Contact a chemical distributor for questions.
6. Some dishmachines come equipped with integral solid detergent dispensers. These dispensers are designed to accom-
modate detergents in a certain-sized container. If applicable, relate this to a chemical distributor upon rst contacting them.
7. Water temperature is an important factor in ensuring that the dishmachine functions properly, and the machine's data
plate details what the minimum temperatures must be for the incoming water supply, the wash tank and the rinse tank. If
minimum requirements are not met, there is a possibility that dishes will not be clean or sanitized.
8. Instruct dishmachine operators to observe the required temperatures and to report when they fall below the minimum
allowed. A loss of temperature can indicate a larger problem—such as a failed heater—or could indicate that the hot water
heater for the operation is not up to capacity and a larger one may need to be installed.
