Cleaning and preventive maintenance (all models)
Note: Do not use bleach to sanitize or clean the ice machine.
Preventive maintenance
Periodic cleaning of Follett’s ice machine 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 ice machine 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.
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 (P/N 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.

on (Fig. 1).
Note: For Ice Manager diverter valve application, refer
to manual 00175273 for ice machine and diverter valve
cleaning process.

Service
Ice machine operation (all models)
Follett’s ice machine consists of ve 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. The evaporator is ooded 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- ushing feature of the ice machine. The
evaporator water is periodically drained and replenished to remove minerals and sediment.
A unique “bin full” detection system is incorporated in the Horizon ice machine. A switch located at the ice discharge port
of the machine detects the position of the transport tube. When the bin lls 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.
