[. . . ] Each sub-system has limits for power, water and temperature. Operational Limitations: Minimum Air Temp (IMS) Air Temp (CU) Water Temp Water Pressure Voltage (IMS) Voltage (CU) 50oF -20oF. 20 psi 104 198 o Do Not operate the machine in conditions beyond these limitations. Scotsman ice systems are designed and manufactured with the highest regard for safety and performance. [. . . ] The vapor and condenser by-pass valves are open during the entire harvest cycle. Clean: The inlet water valve opens to fill the reservoir. The Clean indicator light is switched On. A manually initiated rinse flushes the system. 8 9 7 6 5 4 3 2 1 PUSH BUTTON CONTROL SWITCHES INDICATOR LIGHTS: BIN FULL FREEZE HARVEST CLEAN OFF DIAGNOSTIC LIGHTS: WATER REFRIGERATION Controller Lights and Push Buttons April 2002 Page 27 Eclipseä 600, 800, 1000 Initial Start Up Pre Start A soak-out period of four hours is optional for this system. If desired, powering the compressor unit for four hours prior to start up allows the crankcase heater to warm up the oil in the compressor. Connect power to the condensing unit and move its toggle switch to Run or On. Connect or reconnect power to the ice making section. Observe the lights on the controller: After a few minutes ice will begin to form on the evaporators. When enough ice has formed to nearly empty the water reservoir, the controller will refill the reservoir. The next time the water level drops that far, the ice is ready for release and the Controller will initiate a Harvest cycle. ·The Freeze light goes out and the Harvest light switches on. opens. ·The vapor inlet valve in the ice making section ·In the CP unit, the condenser by-pass valve opens and the liquid inlet valve closes ·All flash on as the power supply is reconnected. Note: Because the condensing unit is external to the ice making section, no visible signs of operation will be noticeable until the water begins to cool and frost forms on the evaporator tubing. Go to the condensing unit and confirm that the compressor and fan motor are operating. Warm air will be discharged from the condenser. ·The Water pump will begin to circulate water May 2002 Page 28 Eclipseä 600, 800, 1000 Purge Adjustment Adjustments Note: While the amount of water purge is adjustable, only those installations with a water supply known to be excellent (very low TDS) should adjust to the minimum setting. See below for purge adjustment instructions. How to Adjust the Amount of Water Purge Adjustment is done by use of the control buttons on the AutoIQ Controller. Examine the next section to become familiar with the AutoIQ Controller before beginning. If the machine is on, push and hold the OFF button for more than 3 seconds, then release it. Push and hold the OFF button for more than 3 seconds (just until all lights flash on) then release it. They should have all flashed once, then certain ones will have turned on to indicate which purge level the machine is set at. There are 5 levels of purge available: Cube Size: Cube size is fixed and cannot be adjusted. Thermostatic Expansion Valve: The TXVs are not adjustable, do not attempt to adjust any of them. [. . . ] ·CME686: Bin Full, Harvest and Clean lights Do NOT operate this machine if the wrong code is displayed. If no button is pushed after 20 seconds the machine will display the Off light and is ready for switch inputs (push and release Freeze to start making ice). Note: The Red Diagnostic Lights will be FLASHING while the program ID is displayed.
