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. 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 Plus™ cleaning/sanitizing solution (part #01050863).
• 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 10minutes
before putting ice machine back into service.

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 (17 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.

“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 ag and switch. Referencing the gure below, the normal running position
of the ag is down, and the switch is closed. When the bin lls to the top and ice can no longer move through
the tube, the machine will force the shuttle ag up, opening the switch and shutting the machine off. The shuttle
actuator, located above the ice bin allows the ice to curl up within it when the bin is full. In this way, there are no
loads generated that would tend to lift off the lid of the bin.

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. During normal operation, the water level rises and falls between the Normal
High and Normal Low probes. As water is consumed to make ice, the level will fall until the Normal Low probe is
exposed, triggering the water feed solenoid on. Water will ll until the Normal High sensor is activated.
Note: The potable water total dissolved solids (TDS) content must be greater than 10 ppm for the water control
system to function properly. If using reverse osmosis water ltration system, ensure TDS level is greater than
10 ppm.

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. 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 ashing green light labeled POWER indicates power to the machine. All other normal operation status indicators
are covered as follows:
Ice machine disposition Operating conditions
1. Ice machine is making ice.
.
2. Ice machine is not making ice.
DIP Switch Settings
1. Normal running.
2. Normal time delay. When the bin lls with ice, the LOW BIN
light goes out momentarily and the refrigeration and auger
drive systems immediately shut down. (Note: The fan motor
will continue to run for 10 minutes to cool condenser) The TIME
DELAY light comes on, initiating the time delay period. When the
time delay expires, the machine will restart provided that the LOW
BIN light is on.
