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.
Specifications Electrical Each icemaker requires its own separate circuit with electrical disconnect within 10 ft (6m). Equipment ground required.
Dimensions and clearances Entire front of icemaker must be clear of obstructions/connections to allow removal. 1" (26mm) clearance above icemaker for service. 1" (26mm) minimum clearance on sides. The intake and exhaust air grilles must provide at least 150 sq in (968 sq cm) of open area. Air-cooled model HCE1000A icemakers – 18" (458mm) minimum clearance between discharge and air intake-grilles.
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 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.
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 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.
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. Error faults: The Horizon PC board monitors various operating parameters including high pressure, auger gearmotor amperage limits, clogged drain, and high and low water alarm conditions.

Refrigeration charge All service on refrigeration systems must be performed in accordance with all federal, state and local laws. It is the responsibility of the technician to ensure that these requirements are met. Recharging icemaker to other than factory specifications will void the warranty.

“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.
