User information
How the dispenser works
Follett’s 25 and 50 automatic load ice and water dispensers receive ice from Follett’s 400 lb (181kg)/day ice machine
located in the dispenser base, in the cabinet top or in a remote location up to 20 ft (6m) away. Ice produced is stored in the
bin section of the dispenser. When the dispense lever is pushed, the wheel motor is energized, causing the wheel to turn.
This moves ice to the dispense chute where it drops by gravity into the container held below the chute.
In Follett’s continuous icemaking process, water freezes to the inside walls of the stainless steel evaporator. A rotating
stainless steel auger carries the ice to the top of the evaporator where it is compressed and extruded through a nozzle
on the outlet port. The ice is then pushed through a tube to the dispenser bin. When the storage area is full, a bin stat
opens and shuts the ice machine off to avoid over- lling of the bin. The ice machine will restart after 20 minutes if the bin
is calling for ice.
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 re ected 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.
How the chilled water accessory works
Follett’s chilled water accessory uses ice from the dispenser’s storage hopper to chill incoming water supplied to the water
station. The water chiller assembly is located in the dispenser cabinet under the storage hopper. As ice is dispensed it is
automatically fed into the water chiller assembly to chill the water coil inside the assembly.

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 information
Wiring diagrams
How unit works — lever models
The dispense wheel motor is energized through the power and ice dispense switches. The water solenoid valve is
energized through the power and water dispense switches. The ice machine receives the bin signal through the power
switch, the normally closed bin thermostat and the ice machine switch. When the bin level thermostat is calling for ice, a
115v bin signal is applied to the bin signal terminals on the ice machine circuit board. When ice builds up around the bin
thermostat, the contacts open, cutting the bin signal to the ice machine.

How unit works — SensorSAFE models
L1
SensorSAFE models provide “touchless” ice and water dispensing. When a container is placed within the actuation
zone below the ice or water chute on SensorSAFE dispenser models, an infrared signal re ects off the container and is
detected by the sensor. The sensor then sends a signal to the control board to activate the appropriate components to
dispense ice or water. LEDs on the board indicate when the board is receiving a signal from the sensors.
A safety, shut-off feature automatically shuts off dispensing after one minute of continuous activation. Dispensing can be
restarted by moving the container away and then returning it to the actuation zone.
Dispensing can be temporarily suspended for cleaning by depressing and releasing the clean switch, located under the
left side of the top front cover. Depressing and releasing the button a second time will return the dispenser to normal
operating state. If the clean switch is not depressed a second time, the dispenser will automatically resume normal
dispense operation (CLN LED goes out) after two minutes. An LED on the control board will light to indicate that the
dispensing has been suspended by activation of the clean switch.
