User information

How the dispenser works

Follett’s 25 and 50 automatic load ice and water dispensers receive ice from Follett’s 181kg (400lb)/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 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 wall 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.

When the bin is full, a bin stat shuts off the icemaker 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 following 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 4L (1gal) hot water into drain pan to keep drain lines clear.

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 237ml (8 oz) household bleach mixed with 3.8L (1gal) 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 19mm (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 19mm (3/4") drain line to chilled water canister.

12. Reinstall splash panel and top front cover.

13. Restore power and test operation.

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.

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

normally closed bin thermostat and the bin signal switch. When the bin level thermostat is calling for ice, a 16V

circuit is completed to the bin signal terminals on the icemaker circuit board.

When ice builds up around the bin

thermostat, the contacts open, opening the circuit to the bin signal terminals on the icemaker circuit board.

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 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 stops the unit from 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.
