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.

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.

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. During normal operation, the water level rises and falls between the Normal
High and Normal Low sensors. As water is consumed to make ice, the level will fall until the Normal Low sensor is
exposed, triggering the water feed solenoid on. Water will fill until the Normal High sensor is activated.
Note: The potable water dissolved solids content must be greater than 10 ppm for the water control system to
function properly. If using reverse osmosis water filtration system, ensure T.D.S level is greater than 10 ppm.

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. A flashing green light labeled CPU is normal and
indicates that the Central Processing Unit “heart beat” is working. All other normal operation status indicators are
covered as follows:

2. Normal time delay. When the bin fills with ice, the LOW BIN
light goes out 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.
3. Normal purge indicator. After a selected period of ice
making time has elapsed (1 or 2 hours), the ice machine will
automatically self-flush. The compressor will shut down but
the fan and gearmotor will continue to run. After the flush is
complete the machine will refill and start without a time delay.

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. There are two types of errors namely
“hard” or “soft”. A hard error is one that shuts the machine off and will not allow restart until the reset button is
pressed. Even cycling power will not reset a hard error. A soft error can either be automatically reset should the
condition rectify, or if power is cycled. Should an error occur, consult the troubleshooting guide in this manual or
a Follett service technician. Note: there are two types of LO WATER and HI AMPS errors as listed below.
Soft errors:
HI AMPS: The PC board monitors the amperage of the auger motor. Should the gear motor experience current
draw above the 3.8 amps limit the machine will shut down and the TIME DELAY, HI AMP, and SERVICE LED’s
will be illuminated. After the time delay the machine will restart and the TIME DELAY, HI AMP, and SERVICE
LED’s 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 120 seconds, a soft error will occur. The machine will shut
down, but the water feed solenoid will remain energized. Should water return, it will fill to the normal low sensor
and the machine will resume normal operation. The error will clear automatically.
DRAIN CLOG: The drain clog sensor, located in the plastic drain pan behind the drain solenoid, will detect the
presence of water just below the top edge of the pan. If water does not properly flow out of the drain pan it will
rise to the sensor, especially during a self-flushing purge cycle.
Hard error:
HI AMPS:
1. “Two strikes” feature. If the gearmotor has a second HI AMP occurrence during the countdown period
(6 hours after a HI AMP time delay) a hard error will occur and the HI AMP and SERVICE LED’s will be
illuminated.
2. No current. To prevent the refrigeration system from running without gearmotor rotation the PC board will
indicate HIGH AMP and SERVICE if the drive relay is energized and there is no current draw.
HI PRESSURE: Should the refrigeration pressure rise above 425 psi, a hard error will occur. Even if pressure
fall-back below the reset point of 295 psi, the error will not clear and the machine will not restart.
LO WATER:
1. There is a sensor in the water reservoir that reaches down to the very bottom. The machine will not start if
water is not present at this sensor.
2. A hard error will occur should water not be present within 60 seconds of power up or if the sensors are
disconnected or damaged.
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.
Comp/Sol output:
The output for the compressor is labeled COMP/SOL.

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.

Refrigerant replacement requirements
1. Non-contaminated refrigerant removed from any Follett refrigeration system can be recycled and returned
to the same system after completing repairs. Recycled refrigerant must be stored in a clean, approved
storage container. If additional refrigerant is required, virgin or reclaimed refrigerant that meets ARI
standard 700-88 must be used.
2. In the event of system contamination (for example, a compressor burn out, refrigerant leak, presence of
non-condensibles or moisture), the system must be repaired, evacuated and recharged using virgin or
reclaimed refrigerant that meets ARI standard 700-88.
3. Follett Corporation does not approve of recovered refrigerants. Improper refrigeration servicing procedures
will void the factory warranty.
Evacuation
Evacuate the system to a level of 500 microns. When the 500 micron level is reached, close all valves. Allow the
system to sit for approximately 20 minutes. During this period the system pressure should not rise. If the system
pressure rises and stabilizes there is moisture in the system and further evacuation is needed. If the pressure
continues to rise check the system for leaks.

Ice capacity test
Icemaker production capacity can only be determined by weighing ice produced in a specific time period.
1.
2.
3.
4.
5.
6.
7.
8.

Replace all panels on icemaker.
Run icemaker for at least 15 minutes.
Weigh and record weight of container used to catch ice.
Catch ice for 15 or 20 minutes.
Weigh harvested ice and record total weight.
Subtract weight of container from total weight.
Convert fractions of pounds to decimal equivalents (ex. 6 lbs 8oz = 6.5 lbs).
Calculate production using following formula:
1440 min. x wt. of ice produced
=

Production capacity/24 hr. period

Total test time in minutes
9. Calculated amount per 24 hours should be checked against rated capacity for same ambient and water
temperatures in Ice Production Tables.

“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. 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.
