AUTOMATIC CLEANING SYSTEM (AuCS

)
This accessory monitors ice making cycles and initiates
cleaning (or sanitizing) procedures automatically. The
AuCS

Accessory can be set to automatically clean or
sanitize the ice machine every 2, 4, or 12 weeks.
Automatic Operation
The following occurs when the toggle switch is in the ICE
position:
• The ice machine control board counts the number of
ice harvest cycles.
•The AuCS

accessory interrupts the ice making
mode and starts the cleaning (or sanitizing) mode
when the harvest count equals the “Frequency of
Cleaning” setting of the AuCS

.
• When the automatic cleaning (or sanitizing) cycle is
complete (approximately 25 minutes), ice making
resumes automatically, and the “Harvest Count” is
reset to zero.
Manual Start Operation
Step 1 Set the toggle switch to the OFF position after
ice falls from the evaporator at the end of a Harvest
cycle. Or, set the switch to the OFF position and allow
the ice to melt off the evaporator.
Step 2 To start the automatic cleaning system, move
the toggle switch to the CLEAN position. The water will
flow through the water dump valve and down the drain.
The Clean light will turn on to indicate the ice machine is
in the Self Cleaning mode. The AuCS

then
automatically adds cleaner or sanitizer to the ice
machine.
Step 3 The ice machine will automatically time out a
ten minute cleaning or sanitizing cycle, followed by six
rinse cycles, (de-energize the Clean light) and stop. This
entire cycle lasts approximately 25 minutes.
Step 4 After the cleaning or sanitizing cycle stops,
move the toggle switch to ICE position.
Step 5
A. The ice machine may be set to start and finish a
cleaning or sanitizing cycle, then automatically
start ice making again.
B. You must wait about one minute into the
cleaning cycle (until water starts to flow over the
evaporator), then move the toggle switch from
CLEAN to ICE position.
C. When the cleaning or sanitizing cycle is
completed, the clean light will turn off and an ice
making sequence will start automatically.
