How the dispenser works
Follett's 12 series automatic-load ice and water dispensers are equipped with Follett's 400 lb (181kg)/day
icemaker. 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 icemaker 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 refl 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.

Cleaning and sanitizing procedures

Solution A: Combine 1 oz. (30 ml) of bleach with 2 gal. (8 L) of hot
water (at least 120 F (49 C) to form a 200 ppm solution of
5.25% sodium hypochlorite, or equivalent.
Solution B: Combine 1/4 oz. (7 ml) of bleach with 2 gal. (8 L) of hot
water (at least 120 F (49 C) to form a 50 ppm solution of
5.25% sodium hypochlorite, or equivalent.
Follett recommends the periodic cleaning schedule below to ensure the
quality of ice provided. Use only recommended cleaning solutions. Do
not use solvents, abrasive cleaners, metal scrapers or sharp objects.
! Warning – Always disconnect power before cleaning.
