    Operation Cleaning and preventive maintenance (all models) Note: Do not use bleach to sanitize or clean the icemaker. Preventive maintenance Periodic cleaning of Follett’s icemaker system is required to ensure peak performance and delivery of clean, sanitary ice. The recommended cleaning procedures that follow should be performed at least as frequently as recommended, and more often if environmental conditions dictate.

    Service Icemaker operation (all models) Follett’s icemaker consists of five distinct functional systems covered in detail as follows: • Water system • Electrical control system • Mechanical assembly • Refrigeration system • Bin full The Horizon icemaker overview The Follett Horizon icemaker uses a horizontal, cylindrical evaporator to freeze water on its inner surface. The refrigeration cycle is continuous;...

  • Page 13: Water System

    Water system The water level in the evaporator is controlled by a feed solenoid and level detecting sensors. Referencing the diagram below, water sensing rods extend down into the reservoir at the end of the evaporator assembly. The system works via electrical conductivity as follows: One of the longest probes is a common.

  • Page 14: Electrical System

    Electrical system Normal control board operation The PC board indicator lights provide all the information necessary to determine the machine's status. Green indicator lights generally represent “go” or normal operation; Yellow indicators represent normal off conditions; Red indicators generally represent alarm conditions, some of which will lock the machine off. A green light labeled POWER indicates power to the machine.

  • Page 15: Test Points

    Test points: The Horizon PC board incorporates on-board test points that can be used to determine various electrical outputs. The test point holes allow a standard probe to be inserted for quick voltage measurement. For 208-230 systems, use TP-4 (L2) as the common for testing outputs for solenoids, motors, etc. Time delay and self-flushing jumpers: The duration of the Time Delay period, the time between normal shut down and restart, is jumper selectable.

  • Page 25: "Bin Full" Detection System

    “Bin full” detection system The Follett Horizon icemaker incorporates a unique “bin full” detection system that consists of the shuttle and actuator. The shuttle incorporates a flag and sensor. Referencing the figure below, the normal running position of the flag is down, out of the sensor. When the bin fills to the top and ice can no longer move through the tube, the machine will force the shuttle flag up into the sensor, shutting the machine off.
