User information
How the dispenser works
Follett’s 25 and 50 automatic load ice and water dispensers receive ice from Follett’s 400 lb (181kg)/day icemaker located
in the dispenser base, in the cabinet top or in a remote location up to 20 ft (6m) away. Ice produced is stored in the bin
section of the dispenser. When the dispense lever is pushed, the wheel motor is energized, 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 stainless steel evaporator. A rotating
stainless steel auger carries the ice to the top of the evaporator where it is compressed and extruded through a nozzle
on the 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 to avoid over- lling of the bin. The icemaker will restart after 20 minutes if the bin is
calling for ice.
How the SensorSAFE accessory works
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 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 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 it is
automatically fed into the water chiller assembly to chill the water coil inside the assembly.
Cleaning and sanitizing procedures
Solution A: Prepare cleaning solution of 200 ppm of available chlorine content. Solution temperature must be
+75F–+125 F (+24 C – +52 C).
Solution B: Prepare sanitizing solution of 50 ppm of available chlorine content. Solution temperature must be
+75F–+125 F (+24 C – +52 C).
Follett recommends the periodic cleaning schedule on page 17 to ensure the quality of ice provided. Use only
recommended cleaning solutions. Do not use solvents, abrasive cleaners, metal scrapers or sharp objects.
Recommended daily cleaning of drain pan
1. Remove all debris from drain pan.
2. Slowly pour 1 gallon (4L) hot water into drain pan to keep drain lines clear.
Recommended weekly cleaning
1. Wash drain pan and grille with Solution A. Rinse thoroughly.
2. Slowly pour solution of one cup (8oz/237ml) household bleach mixed with one gallon (3.8L) hot water into drain pan
to help prevent algae growth in drain lines.
16
Always disconnect power before cleaning.
!
If dispenser is a SensorSAFE unit:
3. Deactivate dispenser by depressing and releasing clean switch located on left side of unit under top front cover.
4. Clean lens using soft cloth and mild, non-abrasive cleaner.
5. Reactivate dispenser by depressing and releasing clean switch a second time (dispenser automatically reactivates
after two minutes).
Recommended semi-annual cleaning of dispenser hopper
Note: If icemaker and dispenser are cleaned and sanitized at the same time, icemaker should be cleaned and
sanitized rst.
1. Remove ice from dispenser.
2. Working inside storage area, remove center thumbscrew from dispense wheel, tilt wheel up toward back to clear
baffle and disengage wheel from motor shaft.
3. Remove front cover, chute cover and clear plastic chute.
4. Wipe lid, wheel, baffle and clear plastic chute with damp cloth wrung out in Solution A.
5. Rinse all above items with damp cloth rinsed and wrung out in clear water.
6. Wipe all bin surfaces (including the area under dispense wheel) with a damp cloth wrung out in Solution A .
7. Rinse all bin surfaces thoroughly with damp cloth rinsed and wrung out in clear water.
Note: Do not rinse by pouring water into the storage bin, damage to the dispense motor can result.
8. Wipe lid, wheel, baffle, clear plastic chute and all bin surfaces with damp cloth wrung out in Solution B to sanitize.
Do not rinse.
9. Reinstall dispense wheel and other components.
If dispenser is equipped with chilled water accessory:
1. Remove four screws securing splash panel.
2. Disconnect 3/4" drain line from bottom of chilled water canister.
3. Loosen (do not remove) screw securing front bracket of chilled water canister to bottom of dispenser hopper.
4. Rotate canister clockwise to release front bracket, then pull canister forward to disengage rear bracket.
5. Remove chilled water coil from canister and clean with cloth wrung out in Solution A.
6. Wipe inside of chilled water canister with cloth wrung out in Solution A.
7. Rinse all above items with damp cloth wrung out in clear water.
8. Sanitize all above items with damp cloth wrung out in Solution B. Do not rinse.
9. Reinstall chilled water coil into canister (rubber alignment grommet on coil tubing must be located outside chilled
water canister to hold coil securely against canister wall).
10. Reinstall chilled water assembly on dispenser and tighten screw securing front bracket.
11. Reconnect 3/4" drain line to chilled water canister.
12. Reinstall splash panel and top front cover.
13. Restore power and test operation.
17
Semi-annual cleaning of icemaker system
Units with icemakers require icemaker cleaning at least every 6 months, and more often if conditions dictate.
Cleaning the icemaker will result in better performance and extend icemaker life. Refer to Icemaker Operation
and Service Manual for speci c cleaning instructions.
To avoid possible damage to motor assembly, use a damp cloth only. Do not allow water to run
through center hole in bottom of bin area.

Service information
Wiring diagrams
How unit works — lever models
The dispense wheel motor is energized through the power and ice dispense switches. The water solenoid valve is
energized through the power and water dispense switches. The icemaker receives the bin signal through the power switch,
the normally closed bin thermostat and the icemaker switch. When the bin level thermostat is calling for ice, a 115v bin
signal is applied to the bin signal terminals on the icemaker circuit board. When ice builds up around the bin thermostat,
the contacts open, cutting the bin signal to the icemaker.
18
How unit works — 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.
