Welcome to FollettFollett ice dispensers enjoy a well-deserved reputation for excellent performance, long-term reliability and outstanding after-the-sale support. To ensure that this dispenser delivers that same degree of service, we ask that you take a moment to review this manual before using the dispenser. Should you have any questions or require technical help at any point, please call our technical service group at (800) 523-9361 or (610) 252-7301.
Before you beginCheck your paperwork to determine which model you have. Following is an explanation of the different model numbers in the U300 series.
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 accommodate most cube/cubelet ices up to 1" square and Follett compressed nugget ice. Crushed, flake, bagged 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 questions concerning your ice type, call Follett’s customer service group at (800) 523-9361 or 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 cleaning instructions to maintain cleanliness of delivered ice.

To start up and operate dispenser 1. Follow all cleaning and start-up instructions in U300 Installation Manual packed with dispenser before
operating dispenser. 2. Turn power switches located under dispenser top to ON position. 3. For manual load models, remove drain pan and fill storage area with compatible ice. (See caution on page 2
of this manual concerning ices which may be used in this dispenser.) 4. For automatic fill models, turn icemaker (bin signal) switch(es) located inside dispenser top to ON position
and begin to make ice. 5. When dispenser has at least 6" (153mm) of ice in storage area, press lever or button to ensure that dispenser
is operating properly.
How dispenser worksFollett’s single-sided U300 series and dual-sided UD300 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/day remote icemakers). An ice water bath beverage cooling system located directly behind valves is available for single-sided U300 series dispensers. Dual-sided units must use a separate mechanical cooling system to cool beverage lines.
In all models, ice is stored below counter in dispenser storage area. When dispense lever or button is pushed, dispense motor is activated. This causes wheel assembly in storage area to rotate counterclockwise, moving ice to vertical auger assembly. Vertical auger carries ice up to dispense chute where it drops by gravity into container.
In automatic load models, ice is manufactured in either one or two Follett remote icemakers. These icemakers may be located up to 20 ft (3m) away from dispenser. As water freezes to inside walls of icemaker evaporator, a rotating stainless steel auger removes ice and carries it to top of evaporator assembly where it is compressed and extruded through an outlet port. The extruded ice is then pushed through tube to storage compartment of dispenser. A bin thermostat shuts off icemaker when storage compartment is full.
Periodic cleaning of dispenser
Solution A: Prepare cleaning solution (200 ppm available chlorine content) of Ecolab Mikro-chlor Cleaner or equal chlorinated detergent. Solution temperature must be at 75˚ – 125˚F (23˚ – 52˚C).Solution B: Prepare sanitizing solution (50 ppm available chlorine content) of Ecolab Mikro-chlor Cleaner or equal chlorinated detergent. Solution temperature must be at 75˚ – 125˚F (23˚ – 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(s) and grille(s) 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 (8 oz/237ml) household bleach mixed with one gallon (3.8L) hot water into drain
pan(s) to help prevent algae growth in drain lines.
Recommended quarterly cleaning (every 3 months) 1. Empty all ice from dispenser. 2. Remove dispenser top and turn bin signal switch(es) and dispenser power switch to OFF position. 3. Remove dispenser drain pan(s) and grille(s). 4. Remove thumbscrews from splash panel, lift up and out at bottom of panel and remove. 5. Remove chute cover(s), dispense chute(s), auger tube and auger (see disassembly instructions).
6
Do NOT run plastic parts (drain pan, dispense chute cover, dispense wheel) through a dishwasher.!
7
6. Remove yoke rods, drive shaft and dispense wheel (see disassembly instructions). 7. Clean all components and bin storage area with Solution A, rinse thoroughly with clear water and sanitize
with Solution B. Caution: To avoid damage to switch, do not immerse chute cover in solution. Wipe only with cleaning cloth.
8. 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.
9. For models with integral ice water bath beverage cooling only: a. Lower Tygon drain tube found on drain connection side of waterbath into PVC waterbath drain and drain
ice water bath. b. Wash bath interior and components with Solution A, using a bottle brush to clean coils. c. Reposition Tygon waterbath drain line in UP position. d. Fill waterbath with Solution A and turn power back on. e. Allow pump to run for 2 minutes to clean pump and pump lines. f. Turn power OFF, drain bath and secure tube in UP position.
Putting unit back in service after quarterly cleaning 1. On units with integral beverage cooling, fill ice water bath manually with potable water. Add ice slowly enough
to avoid spillage over top of waterbath. 2. Reassemble components. 3. For manual load units, turn dispenser power switch to ON position and fill unit with approved ice (see caution
statement page 2). 4. For automatic load units, turn bin signal switch(es) and dispenser power switch to ON position and allow
storage area to fill. 5. When dispenser has at least 6" (153mm) of ice in lower storage area, press dispense button or lever to test
that dispenser is functioning properly.

Temperature lights
Temperature lights provide information on the status of the ice-waterbath. When lighted, the following LEDs indicate:
Low LED: Bath is at optimal temperature for cold drinks.
High LED: Bath temperature is above optimal temperature. The bath will fill with ice for 15 seconds and will then stop for 75 seconds. If temperature is still too high, cycle will repeat.
Error and Low LEDs:After 15 minutes of fill cycling, bath is above 40˚F (4.4˚C).
Error (flashing) LED: Board not receiving signal from sensor.
