User information
How the dispenser works
Follett’s 110 series automatic-load ice and water dispensers are equipped with Follett’s 425 lb (193 kg)/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 SensorSAFE infrared dispensing works
Follett’s SensorSAFE infrared dispensing 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 infrared dispensing 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 infrared dispensing 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.
Quiet Night™/Sleep cycle
The board monitors ice dispensing through a line voltage input to P15. If the ice dispense has not been initiated for
more than 5 seconds during the 20 minute time delay, the SLEEP CYCLE LED comes on. The machine will stay
off for 12 hours unless 5 seconds of dispensing is seen. After 12 hours, the SLEEP CYCLE LED goes out and the
ice making will resume if the bin thermostat is closed. The sleep cycle can be deated using the DIP switches on
the ice machine control board.

12 110CT425A/W, 110FB425A/W
Cleaning and sanitizing
Follett ice machines and dispensers, and their associated cleaning and sanitizing procedures, are designed for
use with potable water sources. The presence, or suspected presence, of infectious agents may call for additional
measures, including the replacement of components and more comprehensive disinfection measures. Follett
recommends that these cleaning and sanitizing procedures be reviewed with the appropriate infectious agent
subject matter experts to assure complete remediation.
Periodic cleaning 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.
Follett recommends sanitizing the pressurized water lines prior to cleaning the ice machine/dispenser. Follett
offers two kits: order P/N 01089572 when a Follett lter system with a pre-lter bowl is present, or P/N 01089580
when a Follett lter system is not present. Follow the instructions provided with the respective kits to sanitize the
pressurized water lines immediately before cleaning the ice machine/dispenser.
Cleaning of the condenser can usually be performed by facility personnel. Cleaning 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
Lever models
The dispense wheelmotor 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 is controlled through an unpowered
contact closure bin thermostat circuit. When ice builds up around the bin thermostat, the contacts open, cutting the
bin signal to the ice machine.
SensorSAFE models
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.
