WARNING WARNING WARNING

FAILURE TO FOLLOW PROPER INSTALLATION
INSTRUCTIONS MAY VOID WARRANTY

PLUMBING CONNECTIONS MUST BE MADE BEFORE POWER IS
CONNECTED TO THE MACHINE. DAMAGE TO THE BOOSTER
HEATER ELEMENTS WILL RESULT OTHERWISE.

PLUMBING

Water Supply: Con nect the machine to a 1/2 inch hot water line.
The minimum incoming water temperature and pressure is 140°F at 25 PSI.
The maximum incoming water temperature and pressure is 160°F at 90 PSI.
Drain: Connect to a 1/2 inch tailpiece in accordance with local plumbing codes.

THIS MACHINE SHOULD BE CONNECTED TO A 115/208 OR 120/240 VOLT
A.C. 4 WIRE, SINGLE PHASE SERVICE FUSED AT 50 AMPS.

FOLLOW THESE STEPS:

1. CONNECT NEUTRAL AND L1 WIRES, LEAVING L2 WIRE
TEMPORARILY DISCONNECTED.

2. a) PUSH "ON-OFF" SWITCH TO "ON-FILL" POSITION.
b) CLOSE DOOR AND TURN HANDLE.
c) PUSH "DE-LIME" SWITCH TO "DE-LIME" POSITION FOR

APPROXIMATELY 1 MINUTE. RETURN TO "OFF"
POSITION.

d) ALLOW MACHINE TO COMPLETE FILL CYCLE.

3. CONNECT THE L2 WIRE.

ELECTRICAL CONNECTIONS SHOULD BE MADE BY A
QUALIFIED ELECTRICIAN IN ACCORDANCE WITH LOCAL
ELECTRICAL CODES.

INSTALLATION PLUMBING

PREPARATION

The warewasher must be installed on a level, rigid surface. Allowance is to be made for water and drain
lines to the unit. When situated, the machine must be completely sealed to the floor using a good grade of
silicone sealant.
Area allowance Width 24" (610 mm)

Height 33-1/2" (851 mm)
Depth 23-1/2" (597 mm)

Remove the packing and dishware racks
from the interior of the warewasher.

WATER
Install a shut -off valve between the supply

and the dishwasher in an accessible
location. Connect the warewasher to the
hot water supply. The incoming water
temperature is

140° F (60° C) minimum and
160° F (71.1° C) maximum. Flow rate is

3.3 Imp. gal., 4 US gal. (13.6 L) per
minute.

Flow pressure:
Minimum 25 psi (172.5 kPa)

Maximum 95 psi (656 kPa)
DRAIN PUMP

Connect 1/2" (12.7 mm) flexhose to 1-1/2" (38 mm) drain piping as per local plumbing code. Drain should
not be in excess of 6 feet (1.56 m) above floor level or at a distance more than 40 feet (12.25 m) away for a
remote location.

ELECTRICAL
Have the heater switch and start switch in "OFF" position. The 500UT needs a six-foot (1.8 m) power cord

with a "U" ground parallel blade plug. Provide a 115/208 or 115/240 V, 60 Hz, A.C. 4-wire, single phase
service fused at 50 amps grounding receptacle in an accessible location within four feet of the warewasher.
This should be installed by a qualified electrician in accordance with the local electrical code specifications.

OPERATION

OPERATING INSTRUCTIONS

1. Be sure screen assemblies are in place.

2. Be sure there is detergent in the detergent container.

3. With door latch open, turn cycle switch to "ON-FILL" Close door, allow machine to fill automatically.

4. Pre-scrap all heavy soils from dishes before loading into machine.

5. Load pre-scrapped dishware into machine.

6. Close door and latch handle. Cycle will start.

7. When cycle light goes out, cycle is complete.

8. Open door, remove clean dishware.
NOTE: The door must be open for three (3) seconds for automatic cycle to reset before starting
another cycle.

9. After initial start -up each day, all other cycles are automatic-just load, close door and place door handle

in locked position to start cycle.

DRAINING THE MACHINE

1. Turn the "ON-OFF" switch to "OFF-DRAIN" position.

2. Close the door.

3. Allow machine to automatically drain (approximately 1-1/2 minutes).

DAILY CLEANING INSTRUCTIONS

1. Drain machine.

2. Remove scrap screens assembly and screen support assembly.

3. Empty and clean scrap screens and screen support assembly.

IMPORTANT: Do not operate the warewasher with the screen assemblies covered with food
particles. Keep the screens clean. Pre -scraping or pre-flushing of dishware to remove heavy, loose

particles of food is recommended. Failure to keep screens clean will result in poor wash results and
could prevent proper draining during cycle.

4. Wipe down the interior of the unit with a mild soap solution, then wipe down with a clean cloth.

5. Replace the screen support and screens.

6. Close door, remove drip tray, clean and replace.

7. At the end of the work day, after completing steps 1 to 6, leave door partially open to allow the machine

wash tank to air-dry overnight.

NOTE: THE WASH TANK SHOULD BE LEFT EMPTIED
OVERNIGHT.

MAINTENANCE

DESCALING

Descaling the warewasher interior may be necessary in areas with hard water. General descaling can be
done by spraying a descaling chemical directly onto the scaled surface until the scale is removed, then
flushing with fresh water.

To descale the interior wash well proceed as follows:

1. With door latch open, set cycle switch to "ON-FILL" Close door and allow machine to fill
automatically with fresh hot water to the normal water level.

2. Open door and add descaler to wash well in the amount recommended by your chemical supplier.

(The usual amount is one to two cups.)

3. Close door to start a wash cycle and immediately set delime switch to "ON." Allow machine to run for
approximately 5 minutes, depending on scale conditions.

4. Set delime switch to "OFF" and allow machine to finish cycle.

5. Run an additional standard wash cycle to ensure that the machine has been entirely rinsed and flushed
of descaling chemical.

WARNING: Descaling chemicals are to be used with caution. Consult your chemical supplier for the
proper use and handling instructions.

Scheduled preventive maintenance practices will greatly increase the efficiency of your machine. A
machine that is well-maintained will not break down as frequently as one which receives only occasional
care. A small investment of a few minutes each day will pay you dividends in the form of many trouble-free
hours of faithful service.

The best maintenance you can give you dishwashing machine is to keep it Clean. By periodically cleaning
and flushing the machine, you can add greatly to its life expectancy. The components of a machine that
suffers from neglect will soon clog up and become inoperative.

SAFETY FEATURES

The warewasher will not operate with the door open. Close the door and turn the handle down until it
reaches the stop position.

CHEMICALS

CHEMICAL INJECTORS

NOTE: IT IS RECOMMENDED THAT A NON
CHLORINATED DETERGENT BE USED.

The built-in chemical injectors will provide accurate dispensing and reliable operation.
Flush the chemical lines once a week with fresh hot tap water to prevent chemical crystalization inside the

chemical tubing and possible damage to chemical pumps.
Place the chemical tubes in a container of hot water and flush thoroughly by holding the prime switch •ON."
Visually inspect the hoses for possible leaks. If any hoses are in need of repair, contact your authorized

service agent. Return the chemical feed lines to their proper chemical containers and reprime them with
chemical.

CHEMICAL SETTINGS

To adjust the chemical
concentration, do the following:

1. Remove the drip tray.

2. Remove the top left -hand screw
from the control box to allow the
front panel to hinge forward.

3. Rotate the cam set by pushing the top
of the cams slowly towards the back of
the warewasher until the locking
screws on the adjustable cams are
accessible.

4. Loosen the lock screw for the chemical to be adjusted and increase or decrease the cam gap as
desired. Increasing the gap in the cam increases the volume of chemical dispensed.

5. Tighten the locking screw sufficiently to ensure the cam will not move.

6. Replace the front panel mounting screw and the drip tray.

7. Operate the machine.

SERVICE INSTRUCTIONS

MAKE CERTAIN THAT THE UNIT IS DISCONNECTED FROM THE POWER
SOURCE BEFORE ATTEMPTING TO SERVICE OR REMOVE ANY
COMPONENT!

1. This unit is permanently lubricated. Oiling is not required. Do not, in any case, open the sealed portion of
the unit or remove housing screws.

2. Periodic cleaning of the pump parts will prolong the LIFE and EFFICIENCY of the pump. Refer to the above
picture for the assembly and disassembly of the pumping head.

3. First remove the three screws on the left. (Do NOT remove other screws which may be exposed.)

4. Lightly clean any corrosion or debris which may clog the impeller. Use a brush and penetrating oil and
lightly scrape to remove encrusted material.

5. Turn the impeller by hand to make sure it turns freely. If it is rotating, install parts in reverse order in which
they were removed.

6. If it does not rotate, if pump is tripping circuit breakers, or not operating properly after cleaning, return to an
authorized service agent. DO NOT attempt repairs yourself.

7. Be certain power cord is in good condition and contains no nicks or cuts.
