User manual SCOTSMAN CME1656R

[. . . ] CME1356R and CME1656R 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 the machine is restarting after it has shut off because the bin was full, the first freeze cycle sequence is like this: 6. Measures the reservoir water temperature. If the machine is operating correctly, the reservoir water 1. temperature will fall at a standard rate. Controller will be checking to see if the water 3. Water valve opens to fill the reservoir. If not, it re-checks the discharge line temperature. If too low, it Shuts Down on a Refrigeration Error. the discharge temperature is acceptable, the water Note: If there is a power interruption, after power is system is checked by shutting off the water pump restored the machine will restart, go thru a brief and determining if the water level goes up enough. Freeze cycle and go thru a 6 minute Harvest cycle. Error Restarts: If it does not, the inlet water valve will open again to fill it. If, after restarting, the water level does not The machine automatically attempts to restart 50 drop, it is assumed that there is a water pump minutes after a shut down. If another problem problem and the machine Shuts Down on a Water occurs in the next cycle, the machine will attempt Error. If another problem occurs in the next cycle, the machine will shut off and must be If the water level does "measure up" the water manually reset. 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 freeze cycle the machine will shut off the water pump. It only does this when the water temperature reaches a preset minimum. The pump will only be off for a few seconds. May 2001 Page 24 CME1356R and CME1656R Technicians Only: Harvest Cycle Sequence & Other Notes Harvest The Purge Valve will be open for 74 seconds. The water pump shuts off, it will restart before 74 seconds, the restart time is based on the Purge Level Setting. The pump restarts and pumps water out of the reservoir until the purge valve closes. The inlet water valve will stay on for about 30 seconds to add enough water to assist with harvest. [. . . ] Close the low side 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. [. . . ]
