AuCS® Automatic Cleaning System 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. AuCS – SI (Internal Mounting) 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 – SI • Internally mounted on S-Series Manitowoc ice machines. • Electricity drawn directly from ice machine. • Can be ordered separately or installed at the factory for no additional cost. AuCS – SO • Electricity drawn from ice machine directly. • Exterior finish is stainless steel. • Only 12" (30.48 cm) wide, 3.43" (8.7 cm) deep, 12.12" (30.78 cm) high. Warranty • 3-year warranty covering all parts and labor 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 AuCS-SO from the factory with the AuCS-SI installed. S-300 If the AuCS-SI is not factory installed, a trained S-322 and qualified technician must perform installation. S-422 Note: Line voltage is obtained from the ice S-1470C machine. Refer to the Model/Serial Plate on S-1870C the ice machine and the AuCS-SI to verify both S-2070C voltages are the same. AuCS-SO Installation: The AuCS-SO is AuCS-SI mounted on the wall near the ice machine or on S-450 the bin with the included bracket and hardware. through Note: Line voltage is obtained from the ice S-1800 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: WEEKS CYCLES 2 1,120 4 2,240 12 6,720 4.75" (12.06 cm) 10.00" (25.4 cm) 5.00" (12.7 cm) AuCS – SI (Internal Mounting) 3.43" (8.71 cm) AuCS – SO (External Mounting) 12.00" (30.48 cm) Automatic Operation: Automatic cleaning initiated by the AuCS system takes approximately 30 minutes to complete.
