User manual SCOTSMAN CME1056

[. . . ] CME1056 INTRODUCTION This product manual contains the information needed for the setup, installation, initial start up, sanitation and maintenance of this ice machine. Be certain that the information applies to the model in question. If no model is listed, the information applies to all models. 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. [. . . ] Air cooled models will switch off the fan motor a few seconds before harvest begins. · · · · · Condenser fan is OFF Water Inlet Valve is CLOSED Water Pump may be ON Compressor is ON Hot Gas Valve is OPEN Controller Operation, Beginning freeze: 1. Switches on the Freeze indicator light and shuts Note: If the freeze cycle exceeds the preset Maximum (30 minutes), the Controller will Shut off the hot gas valve. Opens the water valve to top off the reservoir. Water must fill the reservoir within 250 seconds or 9. At the end of Freeze cycle: the controller shuts the machine down. It will · Water level = below harvest position automatically try to restart in 20 minutes. · Water inlet valve will be off 4. The · Water pump will be ON Controller checks the discharge temperature and · Compressor will be ON cycles the fan every on for 10 seconds and off for · Hot gas valve will be off 20 seconds if the temperature is low. If the discharge temperature exceeds the design maximum, shuts the machine down on a Refrigeration Error. Checks for a "bin full" signal throughout the cycle. At this point Harvest begins and the System Controller switches the Harvest indicator light ON. Restarts: If restarting after shutting off because the bin was full, the first freeze cycle sequence is like this: 6. Measures the reservoir water temperature. machine is operating correctly, the reservoir water 2. temperature will fall at a standard rate. The Controller will be checking to see if the water 3. If not, it re-checks the discharge line temperature. If too low, it Shuts Down on a Refrigeration Error. If the discharge temperature is acceptable, the water system is checked by shutting off the water pump and determining if the water level goes up enough. If it does not, it is assumed that there is a water pump problem and the machine Shuts Down on a Water Error. If the water level does "measure up" the water pump is restarted and the AutoIQ Controller then measures how long it takes to lower the water level. If the water level does not fall, the machine Shuts Down on a Water Error. Once per cycle the machine will shut off the water pump. [. . . ] Remove the gages and replace the stem and port caps. Make certain that they are tightly closed. Refrigeration System Components Due to the expected level of training and experience of a refrigeration mechanic, detailed instructions regarding the replacement of refrigeration components will not be presented. However, critical items will be noted here. [. . . ]
