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 solution.
• DO NOT USE BLEACH.
• It is a violation of Federal law to use these solutions in a manner inconsistent with their labeling.

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.

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.

“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.

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.

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.
Soft errors:
HI AMPS: The PC board monitors the amperage of the auger motor. Should the gear motor experience current
draw above the allowable limit, the machine will shut down and the TIME DELAY and HI AMP will be illuminated.
After the time delay the machine will restart and the TIME DELAY and HI AMP will clear.
LO WATER: During operation, the water level cycles between the normal low and normal high sensors. Should the
water be shut off to a running machine, a soft error will occur. The error sequence is as follows: During operation,
the water level falls to the normal low sensor, and when it does the water feed solenoid is energized. If water is not
detected at the normal low sensor within 10 seconds, a soft error will occur. The machine will shut down, but the
water feed solenoid will remain energized. Should water return, it will ll to the normal low sensor and the machine
will resume normal operation. The error will clear automatically.
HI PRESSURE: Should the refrigeration pressure rise above 425 psi, the machine will shut down and the TIME
DELAY and HIGH PRESSURE will be illuminated. After the time delay, and if the pressure has fallen back below
the reset point of 295 psi, the machine will restart and the TIME DELAY and HIGH PRESSURE will clear.
Hard error:
DRAIN CLOG: The drain clog sensor, located in the chassis will detect the presence of water just below the top
edge of the chassis. After the sensors are dried off, the machine must be reset on the control board to resume
operation.
Run errors:
DRAIN CLOG: When the machine shuts down on a full bin and there has been 30 minutes of cumulative
compressor run time, the machine will purge before starting. During this purge, if water does not get below the low
probe in the reservoir within 20 seconds, the Drain Clog LED will light. The machine will continue to run but this is
an indication of a poorly draining machine and must be addressed.
Relay output indication:
Each relay on the board has an indicator light associated with its output. For example, when the relay for the water
feed solenoid is energized, the adjacent indicator light glows green.
Evaporator ushing sequence:
During operation, the purge solenoid will open in order to drain water. There are two drain settings to choose from:
High TDS or Low TDS. (There is a rocker switch behind the front cover of the machine.) The intent is to drain the
Total Dissolved Solids from the machine while it makes ice.
While ice is being made, the TDS of the water in the evaporator increases in TDS concentration. Without periodic
draining, the TDS levels will climb to very detrimental levels, levels that will cause scale to form and cause poor
machine operation. The Low TDS setting will allow the machine to operate for one hour before going through the
ushing sequence; the High TDS setting will allow the machine to run for 10 minutes before going through the
ushing sequence.
The ushing sequence toggles the purge and ll solenoids three times. That is, the purge solenoid will energize
until the water level drops below the low probe. The ll solenoid then energizes until water reaches the high probe,
and so on for 3 cycles.
Typically, High TDS might be considered levels above 200 PPM, but local experience and varying water chemistry
may compel a High TDS setting for best performance in even lower TDS levels.
Off cycle: At the completion of off-cycle time delay, the machine checks for a cumulative 30 minutes of ice making
time since the last off-cycle ush. If the cumulative ice making time exceeds 30 minutes, the machine will open
the drain valve for 60 seconds to drain the evaporator in its entirety. It will then rell with water and begin making
ice. If the ice making time is less than 30 minutes, the machine will start and begin making ice without draining the
evaporator.
