Welcome to Follett

Follett 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 [phone] or
(888) 2-FOLLETT or [phone].

Before you begin

Check your paperwork to determine which model you have. Following is an explanation of the different model
numbers in the U300 series.

U300BR400A

Condenser type – A = air-cooled, W = water-cooled

Remote icemaker(s) capacity and refrigerant – 400 = 400 lbs (181kg)/day, R404A

800 = 800 lbs (363kg)/day, R404A
absence of = manual fill unit

B = integral beverage cooling. Absence of a B = no integral beverage cooling.

Approximate storage capacity in lbs

Configuration – U = undercounter single-sided, UD = undercounter dual-sided

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
[phone] 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 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 works

Follett’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. 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.

6

Do NOT run plastic parts (drain pan, dispense chute cover, dispense wheel) through
a dishwasher.
