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. Cleaning of the icemaker system,
in most cases, should be performed by your facility’s maintenance staff or a Follett authorized service agent.
Regardless of who performs the cleaning, it is the operator’s responsibility to see that this cleaning is performed
according to the schedule below. Service problems resulting from lack of preventive maintenance will not be
covered under the Follett warranty.
Weekly exterior care
The exterior may be cleaned with a stainless cleaner such as 3M Stainless Steel Cleaner & Polish or equivalent.
Monthly condenser cleaning (air-cooled icemaker only)
1. Use a vacuum cleaner or stiff brush to carefully clean condenser coils of air-cooled icemakers to ensure
optimal performance.
2. When reinstalling counter panels in front of remote icemakers, be sure that ventilation louvers line up with
condenser air duct.
Semi-annual evaporator cleaning (every 6 months)
WARNING
• Wear rubber gloves and safety goggles (and/or face shield) when handling ice machine cleaner or sanitizer.
CAUTION
• Use only Follett approved SafeCLEAN™ Cleaner (part #00132001) and NU-CALGON IMS-II SANITIZER.
• Do not mix Cleaner and Sanitizer solutions together.
• DO NOT USE BLEACH.
• It is a violation of Federal law to use these solutions in a manner inconsistent with their labeling.
• Read and understand all labels printed on packaging before use.
Note: Complete procedure for cleaning an sanitizing MUST be followed. Ice must be collected for 10
minutes before putting ice machine back into service.
1. To clean – Remove cover. Press the CLEAN
button. The machine will drain. Wait for the LO
WATER light to come on (Fig. 1).

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; there is no batch cycle. The evaporator is flooded with water and the level is
controlled by sensors in a reservoir. A rotating auger (22 RPM) continuously scrapes ice from the inner wall of the
evaporator. The auger moves harvested ice through the evaporator into an ice extrusion canal. The ice is forced
through a restrictive nozzle that squeezes out the water and creates the Chewblet. The continuous extrusion process
pushes the Chewblets through a transport tube into a dispenser or bin.
A solid state PC board controls and monitors the functionality of the ice machine. In addition to sequencing electrical
components, the board monitors various operational parameters. A full complement of indicator lights allows visual
status of the machine's operation. Additionally, the PC board controls the self-flushing feature of the icemaker. The
evaporator water is periodically drained and replenished to remove minerals and sediment.
A unique “bin full” detection system is incorporated in the Horizon icemaker. A switch located at the ice discharge
port of the machine detects the position of the transport tube. When the bin fills up with ice, the transport tube
moves out of the normal running position, and the switch turns the ice maker off. A domed housing at the end of the
transport tube contains the ice extrusion loads during shut down.
