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.

Warning - Always disconnect power to dispenser and icemaker before cleaning.

Solution A: Prepare cleaning solution (200 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).

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.

2. Pour 1 cup (284ml) household bleach into drain pan, followed by 1 gallon (3.8L) of hot tap water to flush drains.

SensorSAFE dispensers:

Deactivate dispenser by depressing and releasing clean switch located on left side of unit under top front cover.

Clean lens using a soft cloth and mild, non-abrasive cleaner. Reactivate dispenser by depressing and releasing

clean switch a second time.

Quarterly cleaning - dispenser hopper

1. Remove all ice from dispenser bin.

2. Remove center thumbnut on dispense wheel in bottom of bin and ice baffle at front of bin area.

3. Tilt rear of dispense wheel up and lift to remove.
