How the dispenser works
Follett's 25 and 50 automatic load ice dispensers receive ice from Follett's 400 lb/day icemaker located in the
dispenser base, in the cabinet top or in a remote location up to 20 feet (6 meters) away. Ice produced is stored in the
bin section of the dispenser. On lever and push-button dispensers, when the dispense lever or button is pushed, the
ice dispense solenoid is energized. This opens the gate and activates the dispense motor, 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 evaporator. A rotating stainless
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 dispenser bin. When the storage area is full, a bin stat opens and shuts the
icemaker off.
A level fill circuit maximizes the fill in the bin by rotating the wheel at intervals until the bin is completely filled. When
the bin is filled, a bin stat shuts off the icemaker to avoid overfilling the bin. The icemaker will restart after 20 min. if the
bin is calling for ice.
How the SensorSAFE
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 reflected infra-red
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, or the wheel motor is energized during the level fill cycle, ice is automatically fed into the water chiller
assembly to chill the water coil inside the assembly.
To start-up and operate dispenser
Refer to the 25/50 Series Installation Manual (and Icemaker Installation Manual, form #206428, if unit is equipped with
a remote icemaker) packed with equipment for cleaning and start-up instructions before operating unit.
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.

equal chlorinated detergent. Solution temperature must be 75˚ to 125˚F (24˚ to 52˚C).
Solution B: Prepare sanitizing solution (50 ppm of available chlorine content) of Ecolab Mikro-chlor Cleaner or equal
chlorinated detergent. Solution temperature must be 75˚ to 125˚F (24˚ to 52˚C).
Weekly cleaning – dispenser grille and drain pan
1. Remove grille and wash with Solution A. Rinse thoroughly.
