[. . . ] CME1356 and CME1656 INTRODUCTION This product manual contains the information needed for the setup, installation, initial start up, sanitation and maintenance of this ice machine. There are 2 models covered in this manual: 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. [. . . ] If another problem occurs in the next cycle, the machine will be off and must be manually reset. May 2000 Page 22 CME1356 and CME1656 Technicians Only: Harvest Cycle Operational Sequence Harvest The (air cooled model) fan is off. The purge valve opens, and will remain open for 74 seconds. If the bottom unit is in harvest and receives a signal from the top unit that it is also in Harvest, the bottom unit will stay in harvest for about 6 minutes. If the bottom unit is shut off, but its controller still has power, the top unit may continue to operate. If The water pump shuts off, it will restart in less than the bottom unit's power is shut off, the top unit will 74 seconds, depending upon the Purge Level set. shut down on bin full at the end of the next cycle. If the top unit's power is shut off, it does not impact The water pump restarts and pumps out water thru the lower unit. the open purge valve until the valve closes. An error shut down on one unit does not affect the other. Either may be switched off at the controller. The inlet water valve then opens for about 30 seconds to add some water. Diagnostic Lights and Manual Resets During the Harvest Cycle, ice will be falling from The controller will shut the machine off if a the evaporators and between the ice sensor's malfunction is sensed. The Controller will restart the electric eyes. The AutoIQ Controller monitors the machine 2 times, with a 50 minute interval between ice falling and stays in the Harvest Cycle until ice restarts. If a malfunction is still present after the quits going thru the electric eyes. second restart, the machine will then shut off and The maximum harvest time is 14 minutes. During the restart interval, the machine will be off and a diagnostic code Harvest after a restart will be a long one to establish a base line, then the actual time it took to indicated. release the ice is used to determine the length of The exception to this is lack of water. will always try to re-fill the reservoir every 20 minutes. If no cubes fall (or are sensed) by the end of Maximum Harvest Time, the machine senses a Diagnostic Code Table 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. The machine will not restart for 4 minutes after switching off on Bin Full, unless the freeze button is pressed. [. . . ] After the charge is weighed in, wait a few minutes and re-check the scale. If all of the refrigerant charge has not been weighed into the discharge side, it must be carefully added thru the low side. 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. [. . . ]
