  • Page 27: Controller Operation

    Controller Operation The controller has seven indicator lights and four push buttons. Indicator Lights Bin Full: On when the bin is full, blinks on and off as ice falls during a harvest cycle. Freeze: On when the unit is in the Freeze cycle. Blinks when a freeze cycle is pending.
  • Page 28: Initial Start Up

    The two red lights blink for 20 seconds while some green lights are on. CME810: bin full and harvest. CME686: bin full, harvest and clean. Note: If the light pattern does NOT match – do not start the machine. Install a replacement controller set to the correct program.
  • Page 29: Purge Adjustment

    Purge Adjustment 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.
  • Page 30: System Operation

    Eclipseä 600, 800, 1000 System Operation: This section is intended for the technician. Understanding it is not necessary for the normal operation and maintenance of this ice making system. Major Components: Ice making section sub-system: · Controller, · Ice Sensors, ·...
  • Page 31: Refrigeration Details

    Refrigeration Details: The compressor provides the force that circulates refrigerant in the refrigeration system. During freeze, when the vapor inlet and condenser by pass valves are closed, discharge gas flows from the compressor into the condenser, where its heat is discharged into the air stream. Liquid refrigerant flows out of the condenser and through the normally open liquid line outlet valve on its way to the receiver inlet.
  • Page 32 Eclipseä 600, 800, 1000 Technicians Only: Freeze Cycle Sequence of Operation This sequence begins with a restart after the unit has shut off with the bin full. Ice has been consumed, causing the ice sensors to become un-blocked. 1. The controller switches off the bin full light (four minutes has to have passed since the machine shut off on bin full for the machine to restart) and switches on the Freeze light.
  • Page 33 Technicians Only: Harvest Cycle Sequence of Operation At the beginning of harvest, the controller: · Shuts off the Freeze light · Turns on the Harvest light · Opens the vapor inlet valve · Opens the condenser bypass valve · Closes the normally open liquid inlet valve ·...
  • Page 34: Power And Water Interruptions

    Eclipseä 600, 800, 1000 Power and Water Interruptions Short (less than one second) power interruptions cause no change in operation. Longer interruptions initiate a restart process: · Freeze light blinks on controller · Compressor is off · Vapor inlet valve opens ·...
  • Page 35: Sanitation And Cleaning

    7. Pour 24 ounces of Scotsman Ice Machine Cleaner into the reservoir water. Return the evaporator cover to its normal position. 8. Mix a solution of 8 ounces of Scotsman ice machine cleaner and 1 gallon of warm (95-115 water. Use the solution to scrub the cascading shield and cube deflector in the separate container.
  • Page 36: Other Maintenance

    Eclipseä 600, 800, 1000 Other Maintenance The remote condenser coil must be cleaned occasionally to keep the system operating at high efficiency. · Remove any large debris from the outside of the coil. · Vacuum accumulated dust. · Wash out the coils with water. Caution: Do NOT use excessive water pressure as that will bend the fins.
  • Page 37: Tight Installation Access

    Tight Installation Access Some installations will have very small access to the sides and top of the ice making section. In those cases, alternative methods are available for front access to certain components. Top Panel Removing the top panel allows access over the top of the freezing compartment wall through the notch at the top.
  • Page 38: Water Distributors

    7. Examine the top of the evaporators. The water distribution channels must be free of mineral build up. If build up is present, scrub the channels with Scotsman Ice Machine Cleaner and a plastic bristle brush. 8. Examine the water distributors. Although they...
  • Page 39: Ice Sensors

    Ice Sensors The ice sensors, located in holders in the base of the ice making section, must be clean and free of mineral scale to provide the controller with accurate information. To clean them they must be removed from their installed positions.
  • Page 40: Water Level Sensor Maintenance

    Eclipseä 600, 800, 1000 Water Level Sensor Maintenance In most cases the water level sensor will not require maintenance.
