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.

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.
