Section 3 Ice Machine Operation

QDUAL ONLY

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

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 energize to indicate the ice machine is in the Clean Cycle. Th ice machine will purge water for two minutes. The water fill valve will energize and remain energized until water contacts the water level probe. The AuCS→A will then automatically 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 40 minutes.

Step 4 After the cleaning or sanitizing cycle stops, move the toggle switch to 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 2 minutes into the cleaning cycle (until water starts to flow over the evaporator), then move the toggle switch from CLEAN to ICE position.

After the fluid has been dispensed opening the curtain (bin switch) will interrupt the AuCS→A sequence. The sequence resumes when the curtain closes.

When the cleaning cycle (or sanitizing) is completed, an ice making sequence will start automatically.

Changing Switch Position During Automatic Operation

If the toggle switch is moved to OFF prior to the pump dispensing (less than 2 minutes into the cycle) then switched to:

ICE	A normal ice-making mode begins.
CLEAN	A manual clean cycle begins.
	(See “Manual Start Operation,” page 3-1.)

If the toggle switch is moved to OFF after the pump dispenses (more than 2 minutes into the cycle, but before rinse cycles begin) then switched to:

ICE	The “clean” portion of the cycle begins.
	After completion of the 10-minute
	“Clean” and 6 rinse cycles, the counter
	resets and a normal ice-making mode
	begins.
CLEAN	A manual clean cycle begins.
	(See “Manual Start Operation,” page 3-
	1.)
	After completion of the 10-minute
	“Clean” and 6 rinse cycles, the counter
	resets and the ice machine awaits a
	change in the toggle switch position.

If the toggle switch is moved to OFF after the 6 rinse cycles have begun and then switched from off to:

ICE	The rinse portion of the cycle restarts and
	continues.
	After completion of the 6 additional rinse
	cycles, the counter resets and a normal
	ice-making mode begins.
CLEAN	A manual clean cycle begins.
	After completion of the 10-minute
	“Clean” and 6 rinse cycles, the counter
	resets and the ice machine awaits a
	change in the toggle switch position.
