User information
How the dispenser works
Follett’s 12 series automatic-load ice and water dispensers are equipped with Follett’s 181kg (400 lb)/day ice machine.
In the continuous icemaking process, water freezes to the inside wall of the evaporator. A rotating stainless steel auger
carries the ice to the top of the evaporator where it is compressed and extruded through an outlet port. The ice is
then pushed through a tube to the storage hopper. When the hopper is full, a bin thermostat opens and shuts the ice
machine off. When the dispense mechanism is activated, a dispense motor is turned on, causing the wheel to turn.
This moves ice to the dispense chute where it drops by gravity into the container held below the chute.
How the SensorSAFE accessory works
Follett’s SensorSAFE accessory maximizes sanitation and minimizes the possibility of cross-contamination by
eliminating physical contact between the cup or container and dispenser. Sensors in the panel use reected infrared
light to detect the presence of the container and send a signal to a control board which then activates the appropriate
components for ice or water dispensing.
The SensorSAFE package includes a cleaning switch under the left side of the front cover which temporarily shuts off
dispensing to allow cleaning of the panel and lenses. If the switch is not turned back on after cleaning, the dispenser
automatically resets after two minutes for normal operation.
SensorSAFE also includes a time limit safety feature which automatically stops ice dispensing after one minute of
continuous dispensing. Dispensing can be resumed by moving the container away from the dispenser and returning it
to the activation zone.

Cleaning/descaling and sanitizing
Periodic cleaning/descaling and sanitizing of Follett’s ice and water dispenser and 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 condenser can usually be performed by facility personnel. Cleaning/descaling and sanitizing of
the ice machine system should be performed by your facility’s trained 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.

Service
Important preliminary information
Follett’s ice machine consists of four distinct functional systems.
• Refrigeration system
• Water system
• Harvesting system
• Electrical control system
These four systems work together to accomplish the production and harvesting of ice. A problem in any one of
these system areas will result in improper operation of the entire ice production cycle. When troubleshooting the
ice machine, it is important to analyze the entire system operation to determine which system is not functioning
properly, then pinpoint the component within that system that is malfunctioning. Determine what corrective action
must be taken before making any adjustments or replacing any components.
Note: When performing electrical service, always use a meter to determine whether or no components being
serviced are energized.
The icemaking process
The Follett ice machine uses a stainless steel jacketed evaporator and operates on a continuous freezing cycle. Water
is supplied to the evaporator from the water reservoir where the water level is controlled by a oat valve. This valve
also shuts off the water supply when the ice machine is not running.
When the ice machine is running, a layer of ice forms on the interior surface of the evaporator. This ice is continuously
removed by a rotating (12 RPM) auger. The auger carries the ice upward into the cavity formed by the top bearing
housing and the compression loop, where it is compressed to remove excess water. When the ice reaches the desired
hardness it rotates within the cavity and is forced through a discharge port and compression nozzle and into the ice
transport tube. The discharge tube and compression nozzle are slightly restricted to further compress the ice and
produce the desired high quality. As the formation of ice continues, ice in the transport tube is pushed through the
tube to the storage compartment in the ice dispenser or ice storage bin.
A solid state control board located in the electrical box of the ice machine controls the normal operation of the ice
machine and monitors gearmotor torque on an ongoing basis. This control board will shut down the ice machine
should an over torque condition occur. It is very important that you familiarize yourself with the operational sequences
detailed in this manual before attempting to service the ice machine.
Access to electrical box and control board
The 12 series electrical box has been designed to slide out
for easy access to the control board and more convenient
troubleshooting.
1. Remove top and front panels of dispenser (for panel
removal instructions).
2. Remove electrical box cover.
3. Pull electrical box toward front of unit.
