6. Adjust Dishmachine Flush Time
a) The FLUSH will use fresh water to rinse out the deter-
gent residue and soils in the wash tank before the rinse begins.
The FLUSH time is the time that the drain valve will remain open
at the beginning of the FILL cycle. Avoid making the flush time too
long, which will increase the water usage per machine cycle.
b) In the programming section, increase or decrease the
FLUSH time (PROG DRAIN/FILL menu) as necessary.
7. Measure and Adjust Chemical Concentrations.
8. Check all water and drain fittings for leaks.
9. Instruct machine operators on proper cleaning and operating
procedures.
GENERAL OPERATION SEQUENCE:
CAUTION: Water must be in the wash tank sump while the
wash pump is running in order to avoid damage to the pump
seal.
Close the machine's door. Turn on the machine by pressing the
PUSH ON/OFF button on the front panel. The display will indicate
HEATING WATER while the rinse water is heated in the booster
heater. This heating may take several minutes, depending on how
long the machine has set idle.
When the water in the booster heater reaches the specified tem-
perature, the machine will automatically fill the wash sump with
water (FILLING and the time remaining for filling will be indicated
on the display). The minimum water level should be between the
two score lines on the drain stopper. To adjust the water level, see
programming instructions. During this initial fill, the detergent dis-
pensing pump will run to dispense into the wash tank sump.
The display will indicate OPEN DOOR. Open the door and insert
a rack of soiled dishes. The display will indicate CLOSE DOOR.
Close the door. The display will indicate PRESS START TO
START CYCLE. At any time between cycles, the operator can
press select the NORMAL or HEAVY cycles by pressing the
appropriate button on the keypad. The default cycle is the normal
cycle. When either of these cycle keys is pressed, the display will
momentarily display the selection. The cycle will begin when the
PUSH TO START button on the front panel is pressed.
At the start of the cycle, a PREWASH sequence is initiated and
the wash pump is turned on. The length of this PREWASH
sequence is 20 seconds. PREWASH and the time remaining will
be displayed on the first line of the display. The TEMPERATURE
of the wash water will be displayed on the second line of the dis-
play.
At the end of the prewash sequence, if the wash tank water tem-
perature is less than 120 °F, or if the HEAVY cycle has been
selected, the machine will drain the wash water, and refill the
sump with fresh, heated water from the booster tank. The display
will indicate DRAINING, FLUSH and FILLING and will countdown
the time remaining for each during these steps. Detergent will be
dispensed during the filling sequence. If the detergent dispensing
time is longer than the fill time, the incoming water solenoid valve
will be opened for one second at the completion of the detergent
dispensing, in order to flush out any remaining detergent from the
air gap. No rinse aid or sanitizer are dispensed. At the end of the
prewash sequence, if the temperature of the wash water is greater
than 120 °F and the NORMAL cycles was selected, these steps
are skipped and control goes directly to the washing sequence.
During the washing sequence, the wash pump is turned on.
WASHING and the time remaining will be displayed on the first
line of the display. The TEMPERATURE of the wash water will be
displayed on the second line of the display. If the length of the
DETERGENT WASH is longer than the length of DETERGENT
PREWASH, the detergent dispenser pump will run for the differ-
ence in these time values, dispensing additional detergent into the
wash tank sump. The length of the wash cycle is 45 seconds.
At the end of the wash cycle, if the temperature in the rinse boost-
er tank has not reached 120 °F (regardless of the rinse tank tem-
perature setting), the wash time will be extended until the 120 ° is
reached, or three minutes, whichever is shorter. The display will
indicate EXTENDED WASH.
At the completion of the wash cycle, the machine will drain the
wash water, and refill the sump with fresh, heated water from the
booster tank. The display will indicate DRAINING, FLUSH and
FILLING and will countdown the time remaining for each during
these steps. During the FILLING sequence, rinse aid and sanitiz-
er are dispensed.
The rinsing sequence now begins. RINSING and the time remain-
ing will be displayed on the first line of the display. The TEM-
PERATURE of the rinse water will be displayed on the second line
of the display.
The completion of the rinse sequence is the end of the cycle, and
the display will indicate OPEN DOOR. Detergent is now dis-
pensed into the wash tank sump for the next wash cycle. Open
the door, remove the clean dishes, load a rack of soiled dishes,
close the door and press the start button to start the next cycle. If
the next cycle is started before the completion of the detergent
dispensing, the display will indicate DETERGENT DISPENSE,
and countdown the time remaining until the cycle will automatical-
ly begin.
If the door is opened at any time during a cycle, CLOSE DOOR
will be displayed. The cycle will restart at the beginning of the pre-
wash sequence when the door is closed again.
The cycle counter will only increment when cycles are fully com-
pleted. To display the number of cycles completed, between
cycles, press the CYCLES button on the keypad. Then number of
NORMAL cycles completed will be displayed. Press the CYCLES
button again to display the number of completed HEAVY cycles.
DETERGENT PREWASH - The run time of the detergent dis-
pensing pump before the prewash sequence which controls the
amount of detergent dispensed.
DETERGENT WASH - The run time of the detergent dispensing
pump before the wash sequence which controls the amount of
detergent dispensed.
