10. Collect and discard the first batch of ice. Rinse out the bin. 11. Fill out the Customer Evaluation and Warranty Registration. Send it to Scotsman. 12. Replace the front panel. 13. Inform the user of the location and telephone number of the local service company.
Page 19: Adjustments
Water cooled models use a water regulating valve to control how much cooling water flows thru the water cooled condenser. At the top of that valve, located in the back of the ice machine, is an adjustment stem. To Adjust: 1.
Page 20: How This Machine Works
This section is intended for the technician. It is not necessary for the normal operation and maintenance of the machine. The AutoIQ Controller operates the ice machine by monitoring several input measures and switching various loads on and off. Water System: Water flows into the ice machine during the harvest cycle thru the inlet water valve.

Page 24: Sanitation And Cleaning
CME1056 Sanitation and Cleaning It is the User’s responsibility to keep the ice machine and ice storage bin in a sanitary condition. Without human intervention, sanitation will not be maintained. Ice machines also require occasional cleaning of their water systems with a specifically designed chemical. This chemical dissolves mineral build up that forms during the ice making process.
Page 25: Additional Maintenance
Soak or scrub the distributors in or with a solution of Scotsman Ice Machine Cleaner and warm potable water. 8. Return the water distributors to their normal installed position.

However, critical items will be noted here. Refrigerant: 1. This ice machine uses R-404A or HP62 as a refrigerant. It has several unique characteristics. A. It must use polyol ester refrigerant oil, and that oil is very water absorbent.
Page 37: Before Calling For Service
Before Calling for Service Check the following: 1. Has the water supply to the ice machine or building been shut off? If yes, the ice machine will automatically restart within 25 minutes after water begins to flow to it. 2. Has power been shut off to the ice machine? If yes, the ice machine will automatically restart when power is restored.
