AuCS® Automatic Cleaning System

Warranty

AuCS – SI (Internal Mounting)

An efficient, dependable, and affordable accessory that schedules and performs routine ice machine cleaning automatically.

The innovative AuCS® accessory virtually eliminates the need to have a service technician perform manual cleaning procedures on

the water distribution system of your Manitowoc ice machine.

It is a known fact that regularly scheduled preventative maintenance (cleaning) reduces the total operating cost of any ice

machine. With AuCS, you simply select the cleaning frequency (2, 4, or 12 weeks); AuCS does the rest...automatically. AuCS is also

affordable, as the entire system costs less than the expense of 3 manual cleanings. AuCS-SI and AuCS-SO are designed for use with

only Manitowoc S-Series ice machines.

Cleaning or Sanitizing:

• The AuCS accessory can dispense either cleaner or

sanitizer. It can not dispense both at the same time. Refer

to the Installation Use and Care Manual supplied with the

AuCS accessory to determine the type of solution needed

and proper procedure for changing solutions. Use only

Manitowoc ice machine cleaner or sanitizer.

• Cleaner is used to remove and control build up of lime

scale or other mineral deposits.

• Sanitizer is used to control algae (slime) and other air

borne bacteria (yeast).

AuCS – SO (External Mounting)

Electric

• 115/60/1. 208-230/50/60/1 also available for both

Replenishment

• AuCS cleaning or sanitizing fluid is provided in either 16 oz.

replacement bottles or 1 gallon containers for refilling.

from the date of original installation.

AuCS-SI Installation: The AuCS-SI mounts internally in S-Series ice

machines. S-Series ice machines can be ordered direct from the factory

with the AuCS-SI installed. If the AuCS-SI is not factory installed, a trained

and qualified technician must perform installation. Note: Line voltage is

obtained from the ice machine. Refer to the Model/Serial Plate on the ice

machine and the AuCS-SI to verify both voltages are the same.

AuCS-SO Installation: The AuCS-SO is mounted on the wall near the ice

machine or on the bin with the included bracket and hardware. Note:

Line voltage is obtained from the ice machine. Refer to the Model/Serial

Plate on the ice machine and the AuCS-SO to verify both voltages are

the same.

Setting Run Frequency: AuCS is set to run once approximately every

2 weeks. For less frequent cleanings, set selector switch as needed:

Automatic Operation: Automatic cleaning initiated by the AuCS system

takes approximately 30 minutes to complete. The cleaning procedure

includes a 1-minute cleaning cycle followed by 6 rinse cycles.

Sequence of Operation:

Cleaning or Sanitizing Cycle

The cleaner or sanitizer is dispensed from

the AuCS accessory for 10-20 seconds

during the beginning of the cycle. The

water pump circulates water over the

evaporator for 10 minutes. After 10

minutes of cleaning, the water dump

valve energizes for 45 seconds to dump

the wash water down the drain.

Rinse Cycles

The entire rinse cycle is repeated 6 times.

The water pump circulates water over

the evaporator for 90 seconds. The water

dump valve energizes to dump the rinse

water down the drain for 45 seconds.
