Welcome to Follett Follett equipment enjoys a well-deserved reputation for excellent performance, long-term reliability and outstanding after-the-sale support. To ensure that this equipment delivers the same degree of service, we ask that you review the installation manual (provided as a separate document) before beginning to install the unit. Our instructions are designed to help you achieve a trouble-free installation.

The intake and exhaust air grilles must provide at least 250 sq in (1615 sq cm) of open area. Air-cooled ice machines – 18" (458 mm) minimum clearance between discharge and air intake‑grilles.
Operation Cleaning/sanitizing 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.
“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.
Water system The water level in the evaporator is controlled by a feed solenoid and level detecting sensors. Referencing the diagram below, water sensing probes extend down into the reservoir at the end of the evaporator assembly. The system works via electrical conductivity as follows: The probe labeled B is the 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/Hi-amp overload, wait 5 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 three types of errors namely “soft” (time delay) "hard" (reset), and “run”. §§ Soft errors will automatically reset after the 1 hour time delay or can be reset by cycling power. §§ Hard errors must be reset on the control board. §§ Run errors will give an indication of a problem, but will allow continuous normal operation.

It is the responsibility of the technician to ensure that these requirements are met. Recharging ice machine to other than factory specifications will void the warranty.
Evacuation Evacuate the system to a level of 500 microns. When the 500 micron level is reached, close all valves. Allow the system to sit for approximately 20 minutes. During this period the system pressure should not rise. If the system pressure rises and stabilizes there is moisture in the system and further evacuation is needed. If the pressure continues to rise check the system for leaks. Ambients Minimum Maximum Air temperature1 50 F/10 C 100 F/37.8 C Water temperature2 45 F/7 C 90 F/32.
