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 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 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.

LEDs, when illuminated, indicate the following: PWR (board power), CLN (cleaning, no dispensing cycle), ICE (ice
dispensing activated), WTR (water dispensing activated).
Terminals: LI (incoming power, hot), L2 (neutral terminals), WTR (power terminal for water solenoid), WM (power
terminal for wheelmotor), CLN (terminals for clean cycle switch).
Note: SOL terminal not used in 12 series dispensers.
Lens/sensor troubleshooting
1. Turn dispenser power switch off and remove slash panel.
2. Disconnect wires from WTR and WM terminals on board.
3. Gently remove sensor/mounting block from splash panel.
4. Inspect lens and sensor, clean if necessary.
5. Restore dispenser power and test sensor by passing hand in front of sensor.
6. If LED on board turns on, sensor is operational. Re-assemble dispenser.
7. If LED does not come on switch sensor leads on board and retest.
8. If opposite LED comes on – replace defective board.
9. If opposite LED does not come on – replace defective sensor.
