User information
How the dispenser works
Follett’s 110 series automatic load ice and water dispensers receive ice from Follett’s 181kg (400 lb)/day icemaker located
in the dispenser base, in the cabinet top or in a remote location up to 6m (20 ft) away. Ice produced is stored in the bin
section of the dispenser. When dispensing is activated, 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 thermostat
opens and shuts the icemaker off to avoid over-filling 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 reflected 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 (200 ppm of available chlorine content) of Ecolab Mikro-chlor Cleaner or equal
chlorinated detergent. Solution temperature must be 24˚C – 52˚C
( 75˚F – 125˚F).
Solution B: Prepare sanitizing solution (50 ppm of available chlorine content) of Ecolab Mikro-chlor Cleaner or equal
chlorinated detergent. Solution temperature must be 24˚C – 52˚C
( 75˚F – 125˚F).
Follett recommends the periodic cleaning schedule on page 13 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 4L (1 gallon) hot water into drain pan to keep drain lines clear.
12
Always disconnect power before cleaning.
!

Recommended weekly cleaning
1. Wash drain pan and grille with Solution A above. Rinse thoroughly.
2. Slowly pour solution of one cup (237ml/8 oz) household bleach mixed with 3.8L (1 gallon) hot water into drain pan to
help prevent algae growth in drain lines.
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 quarterly cleaning of dispenser hopper
Note: If icemaker and dispenser are cleaned and sanitized at the same time, icemaker should be completed first.
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 lift wheel out.
3. Remove front cover, chute cover and clear plastic chute.
4. Wipe lid, wheel, baffle, inside of storage area 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 with Solution A .
7. Rinse thoroughly with clear, potable water.
8. Wipe with Solution B to sanitize.
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 right bracket of chilled water canister to bottom of dispenser hopper.
4. Rotate canister clockwise to release front bracket, then slide canister to right to disengage left 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 right 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.
13
Quarterly cleaning of icemaker system
Units with icemakers require icemaker cleaning at least every 3 months, and more often if local water
conditions dictate. Failure to clean icemaker will result in decreased performance and potential damage to
icemaker. Refer to Icemaker Operation and Service Manual for specific 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.

How unit works — lever models
The dispense wheel motor and dispense solenoid are 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.
14

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 infra-red signal reflects 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.

Troubleshooting SensorSAFE board and sensors
Board guide
LEDs, when illuminated, indicate the following:
PWR (board power)
CLN (cleaning, no dispensing cycle)
ICE (ice dispensing activated)
WTR (water dispensing activated)
Terminals:
L1 (incoming power, hot)
L2 (neutral terminals)
WTR (power terminal for water solenoid)
SOL (power terminal for dispense gate
solenoid) not used
WM (power terminal for wheel motor)
CLN (terminals for clean cycle switch)
Action
Check LEDs on control
board
Place cup under drop
zone
LED Status

ON OFF ON
Solution
Check circuit breakers and power switch; restore
power or replace defective switch
Depress clean switch located under left side of front
cover to return board to normal operation
Troubleshoot appropriate lens/sensor and replace if
required (see Lens/Sensor Troubleshooting below)
Verify power on appropriate output terminal
(WTR SOL or WM) on control board and replace
board if required; if board tests okay, troubleshoot
appropriate dispenser component
Problem: Does not dispense ice or water
Action
Check LEDs on control

Solution
Troubleshoot appropriate lens/sensor and replace if
required (see Lens/sensor troubleshooting below)
If there is power on any output terminal (WTR, SOL
or WM) on control board, replace board
Remove lens protective cover; adjust funnel so water
doesn’t drip down lens or behind splash panel
Problem: Dispenses ice or water continuously

Lens/sensor troubleshooting
1. Turn dispenser power switch off.
2. Remove splash panel.
3. Disconnect wires from output terminal(s) (WTR, SOL, WM) on board.
4. Gently remove appropriate sensor/mounting block assembly from panel by moving block sideways until edge of block
clears retaining tab of panel.
5. Inspect lens and sensor assembly for foreign material and remove using non-abrasive cleaner.
6. Turn dispenser power on and test sensor by moving hands through activation area (no closer than1.9mm/3/16") in
front of sensor.
7. If LED on board turns on and off, sensor is working properly and dispenser may be reassembled. If LED does not
come on, switch sensor leads on board and retest. If the opposite LED comes on, board is defective and must be
replaced. If LED does not come on, sensor is defective and must be replaced.

Ice transport tube replacement
Models C/E110FB400A/W, C/E110CR400A/W
1. Remove top and rear access panel from dispenser (lower front panel in
freestanding unit).
2. Disconnect existing ice tube from engaging pin on transport tube bracket in ice
storage bin evaporator and pull down through dispenser chase.
3. Disconnect opposite end of tube from icemaker.
4. Run end of new ice transport tube with 5mm (3/16") hole through ice transport
tube knock-out, (Fig. 5G) in back of dispenser or through counter into bottom of
dispenser, being careful to avoid any bends with less than 153mm (6") radius.
5. Insert tube in internal chase in rear inside corner of dispenser (left side as you
face dispenser) and push up into storage area.
6. Push the 5mm (3/16") hole near end of tube into pin on ice tube bracket
(see drawing below).
Steps 7-8 for units with Satellite-fill icemakers only
7. Install supplied insulation to run of transport tube required for your site, leaving
approximately 51mm (2") of tube exposed at free end.
8. Check that insulated tube runs continuously uphill to dispenser with no dips.
Correct installation of ice transport tube is critical to Satellite-fill icemaker performance. Replacement
ice transport tubes for Satellite-fill icemakers must be insulated and run continuously from icemaker
to dispenser with no dips or bends with a radius of less than 153mm (6").
