    The Horizon ice machine overview The Follett Horizon ice machine uses a horizontal, cylindrical evaporator to freeze water on its inner surface. The refrigeration cycle is continuous; there is no batch cycle. The evaporator is fl ooded with water and the level is controlled by sensors in a reservoir.

  • 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.

    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 fl ashing green light labeled POWER indicates power to the machine.
