Jackson WWS agrees under this warranty to repair or replace, at its discretion, any original part which fails under normal use
due to faulty m aterial or workmanship during the warranty period, providing the equipment has been unaltered, and has been
properly instal l e d , mainta i n ed, and operated in accordance with the applicable factory instruction manual and failure is reported

to an authorized service agency within the warranty period. This includes the use of factory-specied genuine replacement parts,

purchased directly from a Jackson-authorized parts distributor or service agency. Use of generic replacement parts may create a

hazard and void warranty certication.

The labor to repair or replace such failed part will be paid by Jackson WWS, within the continental United States, Hawaii, and Canada,
during the warranty period provided a Jackson WWS authorized service agency , or those having prior authorization from the factory,
performs the service. Any repair work by persons other than a Jackson WWS authorized service agency is the sole responsibility of
the customer. Labor coverage is limited to regular hourly rates; overtime premiums and emergency service charges will not be paid
by Jackson WWS.

ELECTRICAL REQUIREMENTS

i

All electrical ratings provided in this manual are for reference
only . Always refer to the machine data plate to get exact electrical
information for this machine. All electrical work performed on

machines should be done in accordance with applicable
local, state, territorial, and national codes. Work should only

be performed by qualied electricians and authorized service

agents.

Note that all electrical wiring used in the DishStar® series of

machines must be rated, at a minimum, for 212 °F (100 °C), and

that only copper conductors must be used.

Where applicable, heating element amperage draws have been
adjusted for the assumed input voltage. The manufacturer

assumes incoming voltages will be either 208 or 230 Volts. Some

heating elements used in the machines are rated for other voltages,

such as 240 Volts and 480 Volts. Always verify the amperage

draw of the machine in operation when sizing circuit protection.

If the dishmachine is equipped with the optional rinse heater, note
the rinse heater might have its own electrical connection and
require a separate service. Amperage loads for motors and heaters
are indicated on the machine data plate.

INSPECTION

Do not throw away

container if damage is

evident!

UNPACKING

PLUMBING

The plumber must ush

the incoming water line!

Before installing the unit, check packaging and machine for damage. Damaged
packaging might be an indication of damage to the machine. If there is any type
of damage to both packaging and unit, do not throw away the packaging. The
dishmachine has been inspected at the factory before shipping and is expected to
arrive in new, undamaged condition. However, rough handling by carriers or others
might result in damage to the unit while in transit. If this 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 as well as the dealer that
sold you the unit.

The machine should be unboxed and removed from the pallet before installing. Open
the front door and remove all of the materials from inside. Once unpacked, verify there
are no missing parts. If a part is missing, contact the manufacturer immediately.

All plumbing connections must be made to adhere to local, state, territorial, and
national codes. The installing plumber is responsible for ensuring the incoming

water lines are ushed of debris before 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
damage, are not the responsibility of the manufacturer.

A water hardness test

must be performed.

CONNECTIONS:

WATER HARDNESS

HIGHER THAN

5 GPG

07610-004-37-13-E

A water hardness test must be performed. 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, install a water softener or install the
optional HTS-11 (scale prevention and corrosion control). See the Plumbing Options

page for more information on the HTS-11.

If water hardness is higher than 5 GPG and a water softener is not being used, install

the HTS-11 into the water line (1/2” ID pipe size minimum) before the machine’s
incoming water connection point using copper pipe. Observe proper inlet/outlet water

directions (ow directions are molded into the top of the head). It is recommended

that a water shut-off valve be installed before installing the HTS-1 1 to allow access for

service. Plumb from the HTS-11 outlet to the incoming water connection point using
copper pipe (or order the 1/2” ID exible hose kit offered by manufacturer). The water
supply must be capable of a minimum of 10 PSI “ow” pressure at the recommended

temperature indicated on the data plate. See the Plumbing Options page for more
information on the HTS-11.

SHOCK ABSORBER

If water hardness tests at 5 GPG or lower, install the water supply line (1/2” ID pipe

size minimum) to the machine’s incoming water connection point using copper pipe

(or order the 1/2” ID exible hose kit offered by the manufacturer). 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 must be capable of a

minimum of 10 PSI “ow” pressure at the recommended temperature indicated on the

data plate.

The manufacturer has an optional water pressure regulator to accommodate areas

where water pressure uctuates or is higher than the recommended pressure. 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. See the Plumbing Options

page.

It is sug gest ed t hat a sh ock a bso rbe r (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. See the Plumbing Options

page.

CONNECTING THE

DRAIN LINE

PLUMBING CHECK

The dishmachine has a pumped (pressure) drain capable of pumping waste water

to a height of 24” above the oor to the kitchen’s drain system. Each dishmachine is

supplied with a drain hose. When installed, it will extend from the rear side of the ma-

chine. There must 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 12 GPM.

After installing the incoming ll line and the drain line, slowly turn on the water supply

to the machine. Check for any leaks and repair as required. All leaks must be
repaired before operating the machine.

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 possible results. The
unit comes equipped with adjustable bullet feet which can be turned using a pair of
pliers. Since this machine is an undercounter unit, it should be levelled as close as
possible to the unit's location before it is pushed under the counter.

W ASHING A RACK

OF WARE

OPERATIONAL

INSPECTION

Proper preparation of ware will help ensure good results and fewer re-washes. If not
done properly, ware might not come out clean and the efciency of the dishmachine
will be reduced. Putting unscraped dishes into the machine affects its performance,

so scraps should always be removed from ware before 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 they don't hold water during the

cycle. The dishmachine sanitizes as well as cleans. To do this, ware must be properly
prepared before being placed in the machine.

To wash a rack, open the door completely and slide the rack into the unit. Close the
door, ensure the "W ASH/DELIME" switch is on "WASH," press the "Start" button, and

the unit will start. After the cycle light turns off, the cycle is complete. When the ush
light is on (steady, not ashing), tank water should be drained and relled.

Based on use, the strainer might become clogged with soil and debris as the
workday progresses. Operators should regularly inspect the strainer to ensure it has
not become clogged. If clogged, it will reduce the washing capability of the machine.
Instruct operators to clean out the strainer at regular intervals or as required by
workload.
