This manual is organized in the same way as the
expected use of the machine, it begins with
specifications, goes thru unpacking and setup,
shows where everything is; continues with initial
start up, then describes how it works. After that is
the sanitation section, followed by service
diagnosis and repair.

Page 26: Sanitation And Cleaning
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 27: Additional Maintenance
To Sanitize the Ice Storage Bin 1. Remove all ice. 2. Remove baffle. 3. Switch ice machine OFF or wait for it to be in a cleaning cycle. 4. Mix a 1 gallon solution of warm (95-115 and sanitizer. Follow local codes for sanitizer. -

Page 42: Refrigerant
Refrigerant 1. This ice machine uses R-404A or HP62 as a refrigerant. It has several unique characteristics. A. It is a near-azeotrope, and must be liquid charged. B. It must use polyol ester refrigerant oil, and that oil is very water absorbent. The system must not be open for more than 15 minutes. -
Page 43: Liquid Charging
7. With a sight glass or charge faster in the hose to the low side port, start the ice machine. 8. Open the low side service access valve. 9. Crack open the low side manifold valve and watch the scale and sight glass. -
Page 44: 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.
