User manual SCOTSMAN AFE325

[. . . ] AFE325 AFE325 Product Manual Purpose of this manual: To provide detailed installation and operation instructions; to give insights into how the machine works; to list possible causes for problems; and to suggest procedures for specific types of service. The refrigeration system is either air or water cooled, and it uses R-134a as a refrigerant. The control system uses thermostat as a bin control and a water pressure switch as the water safety control. Table of Contents Specifications: . Page 22 A Parts List and Wiring Diagram are located in the center of this manual, printed on yellow paper. August 1994 Page 1 AFE325 Specifications: The finish for this machine is either painted enamel or stainless steel. [. . . ] As the ice machine uses water from the reservoir, continue to add sanitizing solution to keep the reservoir full. After 1/2 of the sanitizer solution has been added to the reservoir, and the reservoir is nearly empty, switch the master switch OFF. Drain the reservoir and thoroughly wash the interior of the reservoir and cover with sanitizer solution. Continue ice making for at least 15 minutes, to flush out any cleaning solution. Add warm water to the ice storage bin and thoroughly wash and rinse all surfaces within the bin. Sanitize the bin interior by thoroughtly washing all interior surfaces of the bin with the balance of the sanitizer solution. Replace the top and the front panels. January 1996 Page 12 AFE325 Maintenance and Cleaning In some areas, the water supply to the ice maker will contain a high concentration of minerals, and that will result in an evaporator and auger becoming coated with these minerals, requiring a more frequent removal than twice per year. If in doubt about the condition of the evaporator and auger, the auger can be removed so the parts can be inspected. Note: Water filters can filter out suspended solids, but not dissolved solids. For more information on removal of these parts, see REMOVAL AND REPLACEMENT. Pull up on cap hook located in the top of the freezer assembly to remove the ice breaker assembly, auger, and the top portion of the water seal. Scotsman Ice Machine Cleaner and a scouring pad work well to clean the auger. Replace the water seal, see the instructions under "Removal and Replacement". Electrical Shock Hazard Disconnect electrical power before beginning. Remove the snap ring and cap, and remove the bolt from the ice breaker and auger assembly to separate the ice breaker assembly from the auger. Pull the ice breaker with bearing out of the top of the evaporator: the auger should stay in the evaporator. Reverse to reassemble. August 1994 Page 13 AFE325 Maintenance: Air Cooled Condenser, Bearings 1. Auger and Bearing Inspection While in most areas regular in-place cleaning with Scotsman Ice Machine Cleaner will be adequate to keep the interior of the evaporator free of excessive mineral build up, some water conditions may require more intense methods. In addition, the auger bearings require physical inspection to determine that they are not wearing. This physical inspection is recommended twice per year for the top bearing and once per year for the auger and both bearings. Whenever the auger is removed, replacement of the water seal is recommended. If a bearing requires replacement, the other bearing must also be replaced. Use threaded rod or a slide hammer puller and screw into the auger, slide the weight up against the stop to remove the auger. [. . . ] Recovery and vacuum equipment should use polyolester oil to minimize cross-contamination. As with any other refrigerant, do not place pressurized air or oxygen into the refrigeration system.
