INDIGO® MODEL HOSE PRIMING The dispenser pump requires priming after initial installation,
or if the hose between the iAuCS® reservoir and pump has been pumped dry or the tubing between the iAuCS® pump and the ice machine has been pumped dry.
Warning
n
Do not blow into or suck on the hose in an attempt to prime it.
Perform the following procedure:
1. Press the CLEAN button.
2. The water pump and dump valve will turn on. The dump valve will shut off after approximately 45 seconds.
3. The control waits until water contacts the water level probe then energizes the iAuCS® pump (22" or 30" ice machines - 30 seconds, 48" ice machines - 60 seconds).
4. Allow the ice machine to complete the cleaning or sanitizing cycle.
Important
The priming procedure starts the automatic cleaning mode. After starting an ice making cycle, the ice machine will run through 6 rinse and dump cycles before making ice.

Caution
,
Wear rubber gloves and safety goggles (and/or face shield) when handling Cleaner and Sanitizer.
Caution
,
Do not mix Cleaner and Sanitizer solutions together. It is a violation of Federal law to use these solutions in a manner inconsistent with their labeling.
Notice
Do not use 1 gallon bottles of Cleaner or Sanitizer on the iAuCS® accessory.
Use the following procedure to flush the system prior to changing from Cleaner to Sanitizer or from Sanitizer to Cleaner.
1. Remove the bottle of Cleaner or Sanitizer from the iAuCS®. Flush the bottle thoroughly then fill with water.
2. Repeat the following until the water bottle is empty (approximately 8 times):
A. Press the CLEAN button.
B. The water pump and dump valve will turn on.
The dump valve will shut off after approximately 45 seconds.
C. The control waits until the water contacts the water
level probe then energizes the iAuCS® pump (22" or 30" ice machines - 30 seconds, 48" ice machines - 60 seconds).
D. Press the POWER button after step C is completed.
3. Install a new bottle of cleaner or sanitizer solution.
INDIGO® MODEL MANUAL START OPERATION Step 1 Press the power button after ice falls from the
evaporator at the end of a Harvest cycle. Or, press the power button and allow the ice to melt off the evaporator.
Notice
Never use anything to force ice from the evaporator. Damage may result.
Step 2 To start the automatic cleaning system, press the CLEAN button. 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 iAuCS® pump energizes automatically to add cleaner or sanitizer to the ice machine.
Step 3 The ice machine will automatically time out a wash cycle, followed by rinse cycles, and stop. This entire cycle lasts approximately 24 minutes for Indigo® Series.
Step 4 The ice machine will start and finish the clean sequence, then automatically start ice making again.
CHANGING SWITCH POSITION DURING OPERATION
If a clean cycle is started and then stopped before the water inlet valve energizes or the water pump starts (45 seconds into the cycle), the clean cycle will be aborted.
If a clean cycle is started and then stopped after the water inlet valve energizes (more than 45 seconds into the cycle) and is then switched to:
ICE MAKING The clean sequence resumes from the point of
interruption. After completion of the cleaning sequence, the counter resets and the ice machine starts making ice.
CLEAN The clean sequence resumes from the point of
interruption. After the clean cycle is complete, the ice machine will stop and wait until either Ice Making or Clean is manually selected.
Part Number 000009036 Rev03 6/18 19
After the iAuCs® pump energizes, the ice machine must complete the wash and rinse cycles before ice making can start.
