Section 3
Ice Machine Operation
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
A 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
A
When the automatic cleaning (or sanitizing)
cycle is complete (approximately 25 minutes,
QDUAL 40 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 re-closes.
NOTE: The harvest count is reset after the AuCS
A
cycle is completed. It cannot be reset by unplugging
the modular wire, changing the switch position,
power loss, etc.
Manual Start Operation
(QDUAL SEE PAGE 3-3)
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. The Clean light will turn on to
indicate the ice machine is in Clean Mode.
The AuCS
A pump energizes automatically to add
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 the ICE position.
Step 5 The ice machine may be set to start and
finish a cleaning (or sanitizing) cycle, then
automatically start ice making again.
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.
When the cleaning (or sanitizing) cycle is
completed, an ice making sequence will start
automatically.
Important
The Q1400C ice machine can not perform step 5.
The toggle switch position must be changed from
CLEAN to ICE after the AuCS
A cycle has been
completed.
