PREPARATION: Before proceeding with the start-up of the unit, verify the following:
1. The strainer is in place and is clean.
2. That the wash and rinse arms are screwed securely into place and that their endcaps are tight. The wash and rinse
arms should rotate freely.
POWER UP: To energize the unit, turn on the power at the service breaker. The voltage should have been previously verified
as being correct. If not, the voltage will have to be verified.
FILLING THE WASH TUB: For the initial fill, close the door and depress the ON/FILL-OFF/DRAIN rocker switch in the ON posi-
tion. The machine will run a partial cycle and fill to the factory preset level. Open the door and verify that the water level is
correct. Hereafter, the water level is controlled by the timer that has been preset at the factory. Verify that there are no other
leaks on the unit before proceeding any further. The wash tub must be completely filled before operating the wash pump to pre-
vent damage to the component. Once the wash tub is filled, the unit is ready for operation.
NOTE: This applies to units with integral booster heaters. Make sure the orange wires at the heater contactor are con-
nected properly. They have been purposely disconnected at the factory to avoid damage to the heater element when
there is no water in the booster heater.
The machine runs a complete cycle to drain and fill. If the machine is not allowed to drain, the water will build up inside the tub.
After the initial fill, the rinse water for the current cycle will become the wash water for the next cycle.
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 simply throwing unscraped dishes into the machine simply defeats 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.
DAILY MACHINE PREPARATION: Refer to the section entitled “PREPARATION” at the top of this page and follow the instruc-
tions 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 that the tub has filled to the correct level. Open the door and the cycle light will illuminate.
When the light goes out, close the door, the unit will start, run through the cycle, and shut off automatically. Repeat this two
more times. The unit should now be ready to proceed with the washing of ware.
WASHING A RACK OF WARE: To wash a rack, open the door completely and slide the rack into the unit. Close the door and
the unit will start automatically. Once the cycle is completed, open the door 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 does, 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.
SHUTDOWN AND CLEANING: At the end of the workday, close the door. Start a cycle, then place the ON/FILL - OFF/DRAIN
SWITCH to the “ OFF/DRAIN” position. The unit will automatically drain and turn off. Once the wash tub is drained, remove he
pan strainer. Remove soil and debris from the strainer and set to the side. Unscrew the wash and rinse arms from their mani-
folds. Remove the endcaps and flush 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 out, 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 strainer and close the door.
