User manual SCOTSMAN CME1056R

[. . . ] CME1056R Introduction This product manual contains the information needed for the setup, installation, initial start up, sanitation and maintenance of this ice machine. 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 Be certain that the information applies to the model the sanitation section, followed by service in question. If no model is listed, the information diagnosis and repair. [. . . ] The electric eyes in the cube The water valve will NOT be open the complete outlet port will also control the machine if the bin length of the harvest cycle. The inlet water valve will "top off" the reservoir at the beginning of the next freeze cycle. The controller measures and compares how long it takes for various events to happen. It stores that data for future reference. Purge Valve May 2000 Page 22 CME1056R Technicians Only: Freeze Cycle Sequence Assuming the machine has been operational, the Freeze cycle begins with the end of the Harvest Cycle: 8. As the machine makes ice, the water level in the reservoir will ultimately fall to the Harvest Level. The first time that happens per freeze cycle the inlet water valve is re-opened and the reservoir is refilled. The next time it happens, the unit will go into a harvest cycle. Note: If the freeze cycle exceeds the preset Maximum (30 minutes), the Controller will Shut Down the machine and switch on the Refrigeration Light. The end of Freeze cycle will see the machine in this state: · · · · Water Inlet Valve is Closed Water Pump is ON Compressor is ON Hot Gas Valve is Open AutoIQ Controller Operation, Beginning freeze: 1. Switches on Freeze indicator light and shuts off the hot gas valve. Opens the water valve to top off the reservoir. The controller checks that water fills the reservoir, if it does not fill up within 250 seconds, the controller shuts the machine down. It will automatically try to restart in 20 minutes. Measures and stores the discharge temperature. · · · · · Water level = below harvest position Water inlet valve will be off Water pump will be ON Compressor will be ON Hot gas valve will be off At this point Harvest begins and the AutoIQ Controller switches the Harvest indicator light ON. 4. If the discharge temperature exceeds the design Restarts: maximum, shuts the machine down on a If the machine is restarting after it has shut off Refrigeration Error. because the bin was full, the first freeze cycle 5. Checks for a "bin full" signal throughout the sequence is like this: cycle. Measures the reservoir water temperature. If the machine is operating correctly, the reservoir water 2. temperature will fall at a standard rate. Controller will be checking to see if the water temperature fall matches that rate. [. . . ] Close the discharge service access valve. With a sight glass or charge faster in the hose to the low side port, start the ice machine. Crack open the low side manifold valve and watch the scale and sight glass. Open and close the low side manifold valve to flow liquid into the manifold but flash off to vapor before it enters the suction side of the refrigeration system. [. . . ]
