120°F minimum 15 - 65 psi
SU-H 110°F minimum 15 - 65 psi
INSTALLATION AND OPERATION
CYCLES
INSTALLATION
Generally, all installations are made by the
dealer or others contracted by the dealer or
owner.
POWER-UP DIAGNOSTICS
When the Power Button is pressed, the control
board checks the probes and sensors to be
within operational range. Once the self-check is
passed, the machine automatically enters Fill/
Preheat Mode.
NOTE: If there is a detectable water level in the
sump prior to turning the machine on, the
dishwasher will perform a power drain.
PRIMING CHEMICAL PUMPS
Chemical pumps prime on Power Up or at the
start of a Wash Cycle if sensors do not detect
chemicals.
1. Initial prime attempt is 60 seconds.
A. If chemical not sensed "Add Chemical" will
display.
NOTE: The 60 second prime is in intervals of 6
seconds.
2. If not primed after 3 attempts, the "Add
Chemical" indicator will continue to display.
3. Priming is terminated.
4. Reset by cycling power.
5. Once chemical is sensed, pumps continue to
prime for 10 seconds to allow chemicals to reach
machine.
FILL/PREHEAT
Without Booster (SG & SU-L): The holding
tank will fill. The water is then moved through the
rinse arms to the sump. Process repeats until
the sump is at operational water level. Sump
heater maintains wash temperature.
With Booster (SU-H): The booster will fill and
heat to 140°F. The booster water is then moved
through the rinse arms to the sump. Process
repeats until the sump is at operational water
level. Sump heater maintains wash
temperature.
NOTE: If the door is opened during the Fill
cycle, the process is suspended. After door is
closed the process continues where it left off.
NOTE: During the Fill cycle, the detergent pump
is activated for the normal detergent cycle.
READY MODE
While a cycle is not in process, the SU and SG
Series will maintain in idle state. In this mode,
the heat will be maintained in both the sump and
booster. The sump temperature will be
displayed.
NORMAL OPERATION (WASH CYCLE)
After the fill cycle is completed, a wash cycle is
begun by pressing the WASH key.
On 120VAC cold machines, sump heater is de-
energized while wash motor is energized.
If the door is opened during the Wash cycle, the
process is suspended. After door is closed the
process continues where it left off.
During a cycle, both sump and booster heat are
controlled. Hot machines only.
During the wash portion of the cycle, the sump
temperature will be displayed. During the rinse,
the final rinse temperature will be displayed.
