It will operate satisfactorily under a wide variety of conditions. Do NOT operate the machine in temperatures it has not been designed for. [. . . ] This warms up the evaporators and the surface of the ice frozen to the evaporator surface melts. Ice then falls into the bin.

As the machine makes ice, the water level in the reservoir will ultimately fall to the Harvest Level . · · · · · Condenser fan is OFF Water Inlet Valve is CLOSED Water Pump may be ON Compressor is ON Hot Gas Valve is OPEN · WRF560SMYE fills the reservoir once at the The Controller, from the start of the freeze cycle: beginning of Freeze · CME456 fills the reservoir at the beginning of freeze and one more time about ½ way through freeze. Air cooled models will switch off the fan motor a 1. Switches on the Freeze indicator light and shuts few seconds before harvest begins. Note: If the freeze cycle exceeds the preset 2. Opens the water valve to top off the reservoir. Maximum (45 minutes), the Controller will shut the Water must fill the reservoir within 130 seconds or unit off. At the end of Freeze cycle: automatically try to restart in 20 minutes. The Controller checks the discharge temperature and cycles the fan(s) on every 12 seconds and off for 20 seconds (CME456) or 45 seconds (WRF560SMYE) if the temperature is low. If the discharge temperature exceeds the design maximum the controller shuts the unit off. Checks for a "bin full" signal throughout the cycle. · · · · · · Water level = below harvest position Condenser fan will be off 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. the open purge valve until the valve closes. The machine will always try to re-fill the reservoir every 20 The inlet water valve then opens for about 22 minutes. During the Harvest Cycle, ice will be falling from the evaporators and between the ice sensor's electric eyes. The AutoIQ Controller monitors the ice falling and stays in the Harvest Cycle until ice quits going thru the electric eyes. The first Harvest after a restart will be a long one to establish a base line, then the actual time it took to release the ice is used to determine the length of the next harvest cycle. If no cubes fall (or are sensed) by the end of Maximum Harvest Time, the machine senses a refrigeration error. If the next cycle also produces a refrigeration error, the machine Shuts Down. Note: The last harvest cycle before shutting off on bin full is 6 minutes long, unless the shut down was initiated by a closed Bin Thermostat. In that case the last harvest cycle will be normal. The machine will not restart for 4 minutes after switching off on Bin Full, unless the freeze button is pressed. Note: If during a Bin Full shut down, the machine has not restarted for 12 hours, the compressor will run for 30 seconds to clear its oil of refrigerant. [. . . ] 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. This ice machine uses R-404A or HP62 as a refrigerant. [. . . ]
