Installation
Before you begin
§ All dispensers must be installed level in both directions to ensure proper operation.
§ SensorSAFE™ dispensers are shipped with a plastic, protective lm on sensor lenses. For proper operation,
plastic lm must be removed after installation.
Installing freestanding dispensers
1. Position dispenser in desired location and adjust legs to level in both directions.
2. Connect water supply to 3/8" FPT tting on back of dispenser (Fig. 1).
3. Connect separate drain lines to 3/4" MPT dispenser drain tting, and 3/4" MPT ice machine drain tting
on back of dispenser.
4. Run drain lines to wall or oor drain. If ice machine drain tting is below an intended wall drain, a
condensate pump must be used.
5. If ice machine is a water-cooled unit, connect water-cooled condenser supply line to 3/8" FPT condenser
inlet tting on back of dispenser.
Note: Do not run condenser supply water through ice machine water lter system.
6. Connect condenser drain line to 3/8" FPT condenser outlet tting on back of dispenser.
Important: Do not connect condenser drain line to any other drain lines.
7. Plug dispenser into 15A rated NEMA 5-15 wall socket.
8. Remove front cover of base section by removing two screws at bottom corners of cover. Allow cover to
drop approximately 3/8" (5 mm) and pull forward.
9. Turn on water supply and check for leaks.

User information
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 reected
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
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 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.
Follett recommends sanitizing the pressurized water lines prior to cleaning the ice machine/dispenser. Follett
offers two kits: order P/N 01089572 when a Follett lter system with a pre-lter bowl is present, or P/N 01089580
when a Follett lter system is not present. Follow the instructions provided with the respective kits to sanitize the
pressurized water lines immediately before cleaning the ice machine/dispenser.
Cleaning of the condenser can usually be performed by facility personnel. Cleaning 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.

Ice Machine and Dispenser
Cleaning Procedure
Note: Check drains and drain cup to ensure they are open and owing freely.
1. If ice machine was running recently, ensure that the evaporator is completely free of ice before
proceeding. If there is ice in the evaporator, complete steps 2-7 using only hot water to remove the ice,
then begin Cleaning/Descaling Procedure again.
2. Remove front cover of the dispenser and turn OFF bin signal switch.
3. Dispense all ice from storage hopper and discard.
4. Remove the cover of the base stand.
5. Press CLEAN switch. The MAINTENANCE light will turn on and the machine will drain. Wait for the LOW
WATER light to turn on.
6. Remove lid from cleaning cup and ll (about 1 quart) until SafeCLEAN Plus solution completely lls the
reservoir. Place lid back on cup. Save remainder of SafeCLEAN Plus solution.
7. CLEANER FULL light will turn on and machine will start cleaning cycle, then rinse three times; this
process takes approximately 15 minutes.
8. While ice machine is cleaning/descaling, clean dispenser as follows:
a. Turn OFF dispenser power.
b. Remove hopper lid.
c. Remove knurled nuts from front of storage hopper.
d. Remove stud assembly, baffle, wheel, and any remaining ice.
e. Remove dispense chutes from splash panel.
f. Submerse drain grille in SafeCLEAN Plus solution and allow to soak to remove any scale buildup.
g. Wipe inside of hopper lid, stud assembly, baffle, wheel, inside of storage area, dispense chutes, drain grille
and drain pan with damp cloth wrung out in SafeCLEAN Plus solution. Thoroughly rinse all parts with damp
cloth wrung out with clean water.
Note: To avoid possible damage to motor assembly, only use a damp cloth to clean storage hopper. Do
not allow water to run through motor shaft hole in bottom of hopper.
9. When machine is nished cleaning, the MAINTENANCE light will turn off.
Finish cleaning – SafeCLEAN Plus only
10. If the dispenser is equipped with a Chilled Water Accessory continue to Step 10.a; if not, skip to Step11.
