User information

How the dispenser works

Follett’s 12 series automatic load ice and water dispensers are equipped with Follett’s 400 lb (181kg)/day icemaker. In
Follett’s continuous icemaking process, water freezes to the inside walls 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 stat opens and shuts the icemaker 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 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 infra-red 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.

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 75˚F – 125˚F
(24˚C – 52˚C).

Solution B: Prepare sanitizing solution (50 ppm of available chlorine

content) of Ecolab Mikro-chlor Cleaner or equal chlorinated
detergent. Solution temperature must be 75˚F – 125˚F
(24˚C – 52˚C).

Follett recommends the periodic cleaning schedule below to ensure the quality
of ice provided. Use only recommended cleaning solutions. Do not use
solvents, abrasive cleaners, metal scrapers or sharp objects.

1. Remove all ice from storage hopper.

2. Remove center thumbscrew, locking plate, two wingnuts and backing plate
from front of storage hopper.

3. Remove stud assembly, agitator, spacer, baffle, wheel and drive bar in this
sequence.

4. Remove dispense chute.

5. Wipe lid, wheel, baffle, inside of storage area and dispense chute
with damp cloth wrung out in Solution A.

Icemaker cleaning & sanitizing

Condenser cleaning - monthly

1. Use vacuum cleaner or stiff brush to carefully clean condenser coils of air-cooled icemaker to ensure optimal
performance.

2. When reinstalling louver panels on side of dispenser, be sure ventilation louvers are facing down in order to prevent
water, dust and other debris from falling into system.

Icemaking cleaning - quarterly

The icemaking system can be cleaned in place without disassembling the water system. This cleaning process
should be performed 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.

1. Disconnect power to unit.

2. Remove front panel (as shown on page 30) to gain access to water reservoir and electrical control box.

3. Turn compressor switch on electrical box to OFF position.

4. Remove water reservoir cover and block up reservoir float.

5. Drain water from reservoir and evaporator using evaporator drain hose teed off evaporator supply hose.

6. Following manufacturer's instructions, prepare 3 pints (1.4L) Calgon Ice Machine Cleaner or equivalent. Cleaning
solution temperature must be 65˚ - 85˚F (18˚ - 29˚C).

11

Preventive maintenance

Periodic cleaning of Follett’s icemaker system is required to ensure peak performance and delivery of
clean, sanitary ice. The recommended cleaning procedures which follow should be performed at least as
frequently as recommended below and more often if environmental conditions dictate.

Cleaning of the condenser can usually be performed by facility personnel. Cleaning of the icemaker system
in most cases should be performed by your facility’s 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.

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.

!

7. Plug evaporator drain hose and pour part of cleaning solution into reservoir, filling almost to overflowing.

8. Remove stainless steel compression nozzle and submerge in cup of cleaning solution while cleaning rest of system.

9. Restore power to icemaker (gearmotor will now run, but compressor and fan motor will not).

10. After 15 minutes, turn power off and drain cleaning solution from reservoir and evaporator.

11. Plug drain hose and secure in mounting position.

12. Rinse compression nozzle in clean water and reinstall on evaporator outlet.

13. Clean evaporator drain pan and drain lines with liquid ice machine cleaner (remove left side panel for access, as
shown on page30.)

14. Following manufacturer’s instructions, prepare 1 gallon (3.8L) Calgon Ice Machine Sanitizer or equivalent. Sanitizing
solution temperature must be 65˚ - 85˚F (18˚ - 29˚C).

15. If ice bin cleaning is also needed at this time, remove all ice from ice storage area and allow ice made during
sanitizing process to fall into ice bin area.

Note: If storage hopper will not be cleaned at this time, connect a separate ice transport tube to

evaporator and divert ice into separate container.

16. Fill reservoir almost to overflowing with sanitizing solution.

17. Restore power to icemaker and turn compressor switch to ON position.

18. As unit starts to make ice, continue to pour sanitizing solution into reservoir, maintaining level just below reservoir
overflow.

19. Continue to make ice until you have used 1/2 gallon (1.9L) sanitizing solution.

20. Unblock float, replace reservoir cover and continue to make ice for at least 15 minutes to flush all sanitizing
solution from system.

21. Switch compressor switch to OFF position.

22. Wash storage hopper with remaining sanitizing solution and rinse with potable water.

23. Switch compressor switch to ON position.

24. Replace any panels removed prior to cleaning.

Start-up following cleaning

1. Clean and sanitize ice storage area of dispenser in accordance with instructions above before making ice.
