ACCESSORY MANUAL START OPERATION
This accessory monitors ice making cycles and
initiates self-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.
CAUTION
Refer to the AuCS

Accessory Installation - Use
and Care Guide for complete details on the
installation, operation, maintenance and cautionary
statements of this accessory.
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 automatic 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.
Important
Opening the curtain switch will interrupt the
cleaning or sanitizing sequence. The sequence will
resume from the point of interruption when the
curtain recloses.
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.
CAUTION
Never use anything to force ice from the
evaporator. Damage may result.
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. (New style circuit boards will also energize the
Clean light.) The AuCS

then automatically adds
cleaner of 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
self-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 self-cleaning cycle or sanitizing is
completed, an ice making sequence will start
automatically.
