Important cautions
• Storage area of dispenser contains mechanical, moving parts. Keep hands and arms clear of
this area at all times. If access to this area is required, power to unit must be disconnected first.
• Follett manual load units can accommodate most cube/cubelet ices up to 1" square, or Follett
compressed nugget ice. Crushed, flake, bagged, nugget or congealed ice cannot be used. Use of
these ices can jam dispenser and void warranty. Separate any “waffle-like” sections of cubes
before adding to dispenser. If you have any questions concerning your ice type, please call
Follett’s customer service group toll free at (800) 523-9361 or (888) 2-FOLLETT or (610) 252-7301.
• Follett recommends use of an activated carbon filter for units equipped with icemakers
• Ice is slippery. Maintain counters and floors around dispenser in a clean and ice-free condition.
• Ice is food. Follow recommended cleaning instructions to maintain cleanliness of delivered ice.

How the dispenser works
Follett’s U150 series ice dispensers are available in manual load configurations (using ice from another source)
or automatic load configurations, fed from one or two Follett 400 lb (181kg)/day remote icemakers.
In all models, ice is stored below the counter in the dispenser storage area. When the dispense lever or button is
pushed, the dispense motor is activated. This causes the wheel assembly in the storage area to turn, moving ice
to the vertical auger assembly, which carries ice up to the dispense chute where it drops by gravity into the
container.
In automatic load models, ice is manufactured in either one or two Follett remote icemakers. These icemakers
may be located up to 20 feet (3m) away from the dispenser. As water freezes to the inside walls of the icemaker
evaporator, a rotating stainless steel auger removes ice and carries it to the top of the evaporator assembly
where it is compressed and extruded through an outlet port. The extruded ice is then pushed through the tube to
the storage compartment of the dispenser. A level fill circuit maximizes fill in the storage area by rotating the
wheel at intervals until the bin is completely filled. When the bin is filled, a bin stat shuts the icemaker off to avoid
overfilling of the bin. U150 dispensers equipped with R4A/W (R12 refrigerant) icemakers have a safety
thermostat that prevents the icemaker from restarting for 15 to 30 minutes after the bin stat has shut the icemaker
down. In U150 dispensers with R5A/W (R22 refrigerant) icemakers, the icemaker will restart after 15 to 20
minutes if the bin is calling for ice.
From Serial Number 40600 and up, models with integral ice-waterbath beverage cooling are equipped with a
waterbath timer circuit that activates the waterbath pump 1 minute on and 10 minutes off to ensure optimal
beverage cooling.
To start-up and operate dispenser
1. Follow cleaning instructions in U150 Series Installation Manual before operating dispenser.
2. Follow start-up instructions in U150 Series Installation Manual for beverage line hook-up instructions, initial
loading of ice-waterbath beverage cooling system, manual loading restrictions and/or automatic load start-up
requirements.
3. Turn power and feed switches located inside beverage rail or ice tower to ON position.
4. For manual load models, remove front drain pan or rear lid and fill storage area with compatible ice.
5. For automatic fill models, turn icemaker (bin signal) switch(es) located inside beverage rail or ice tower to ON
position and begin to make ice.
6. When dispenser has at least 6" (153mm) of ice in storage area, press PUSH FOR ICE lever or button to
insure that dispenser is operating properly.

Periodic cleaning of dispenser
Caution: Do NOT run plastic parts (drain pan, dispense chute cover, dispense wheel) through a
dishwasher.
Solution A: Prepare a cleaning solution (200 ppm of available chlorine content) of Ecolab Mikro-chlor Cleaner or
equal chlorinated detergent. Solution temperature must be 75˚ to 125˚F (24˚ to 52˚C).
Solution B: Prepare a sanitizing solution (50 ppm of available chlorine content) of Ecolab Mikro-chlor Cleaner or
equal chlorinated detergent. Solution temperature must be 75˚ to 125˚F (24˚ to 52˚C).
Recommended daily cleaning of drain pan
1. Remove all debris from drain pan.
2. Pour 1 gallon (4L) hot water into drain pan to keep drain lines clear.
Recommended weekly cleaning
1. Remove drain pan and grille and wash with Solution A above. Rinse thoroughly.
2. On units with beverage valves, remove nozzles and diffusers from valves, soak for at least 10 minutes in
cleaning Solution A, rinse, sanitize with Solution B and reinstall.
3. Pour a solution of one cup (8oz/237ml) household bleach mixed with one gallon (3.8L) hot water into drain
pan to help prevent algae growth in drain lines.
Recommended quarterly cleaning (every 3 months)
Caution: Remove dispense switch from dispense chute before cleaning chute.
1. Turn power switch to OFF position.
2. Remove ice from storage area.
3. Remove dispense chute, chute cover, auger tube and auger (page 10).
4. Remove drain pan, grille, dispense wheel and waterbath cover plate (page 11).
5. Clean all components and bin storage area with Solution A, rinse thoroughly with clear water and sanitize
with Solution B.
6. On units with beverage valves, remove nozzles and diffusers from valves, soak for at least 10 minutes in
cleaning Solution A, rinse, sanitize with Solution B and reinstall.
7. For units without integral beverage cooling, clean area below wheel and stainless cover plate with Solution A,
rinse and sanitize with Solution B.
8. For models with integral ice-waterbath beverage cooling only:
• Lower drain tube found on utility connection side of dispenser and drain ice-waterbath
• Use a bottle brush to clean coils with Solution A, rinse and sanitize with Solution B
• Reposition waterbath drain line in UP position
• Pour 3.5 gallons (13L) Solution A into waterbath
• Turn power ON and tape dispense lever or dispense button back in “Dispense” position
• Allow pump to run for 2 minutes to clean pump and pump lines
• Turn power OFF and remove tape
• Drain bath and replace drain tube in UP position to avoid siphoning waterbath water
Putting unit back in service after quarterly cleaning
1. On units with integral beverage cooling, fill ice-waterbath with 3.5 gallons (13L) potable water.
2. Reassemble components.
3. For manual load units, fill unit with an approved ice (page 2).
4. For automatic load units with R4A/W (R12 refrigerant) icemakers, turn icemaker switch(es) and dispenser
power switch to ON position and allow storage area to fill.
5. For automatic load units with R5A/W (R22 refrigerant) icemakers, turn bin signal switch(es) and dispenser
power switch to ON position and allow storage area to fill.
6. Push dispense button or lever to test that dispenser is functioning properly.
Quarterly cleaning of icemaker system
Units equipped with icemakers require cleaning of icemaker system at least every three months, and
more often if local water conditions dictate. Failure to clean icemaker system will result in decreased
performance and potential damage to icemaker. Refer to Icemaker Operation and Service Manual.
