  • Page 30: Control System

    Control System The control system operates the ice maker. The control board operates on 12 VAC, supplied by the transformer. It uses an ultrasonic ice sensor to measure the ice level. The ultrasonic system transmits sound waves into the ice storage bin and measures the return time. When the return time is longer than the pre-set time for a full bin, the control board switches the ice maker to an ice making mode.

  • Page 31: Water System

    Water System The auger is driven at approximately 11 RPM by the gear reducer. The gear reducer is a sealed component and does not require lubrication, as it contains a charge of grease. The auger motor drives a set of gears that all together reduce the motor speed to the 11 RPM output speed, and correspondingly increases the torque.

  • Page 32: Storage

    Storage The ice storage system is made up of a plastic lined ice storage bin, covered by an insulated top panel and an insulated swing open door with gasket. The ice storage bin is foamed in place, so the side panels are not removable.
