How the dispenser works

Follett's 25/50 series automatic-load ice and water dispensers are equipped with Follett's 425 lb (181kg)/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 reflected 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.

Cleaning/descaling 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/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.
