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. Cleaning of the condenser can usually be performed by facility personnel.

Service Ice machine operation (all models) Follett’s ice machine consists of five distinct functional systems covered in detail as follows: • Water system • Electrical control system • Mechanical assembly • Refrigeration system • Bin full 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.
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. When water is between any of the other probes and the common, the PC board will sense the activation.
Electrical system ATTENTION! To prevent circuit breaker overload, wait 15 minutes before restarting this unit. This allows the compressor to equalize and the evaporator to thaw. Normal control board operation The PC board indicator lights provide all the information necessary to determine the machine's status.
Error faults: The Horizon PC board monitors various operating parameters including high pressure, auger gearmotor amperage limits, clogged drain, and low water alarm conditions. There are two types of errors namely “hard” or “soft”. A hard error is one that shuts the machine off and will not allow restart until the reset button is pressed. Even cycling power will not reset a hard error. A soft error can either be automatically reset should the condition rectify, or if power is cycled.

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