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 beginning the installation of the dispenser. Should you have any
questions or require technical help at any point, please call our technical service group, (800) 523-9361 or
(610) 252-7301.
Before you begin
After uncrating and removing all packing material, inspect the equipment for concealed shipping damage. If
damage is found, notify the shipper immediately and contact Follett Corporation so that we can help in the filing of
a claim, if necessary.
Check your paperwork to determine which model you have. Follett model numbers are designed to provide
information about the type and capacity of Follett ice dispensing equipment. Following is an explanation of the
different model numbers in the VU300 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.
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.
Always disconnect power before cleaning or servicing the dispenser.
Failure to remove all sanitizer may result in health hazard.
Follett manual load dispensers 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. For ice compatibility questions, please call Follett customer service at
(800) 523-9361 or (610) 252-7301.

2. Place support blocks in cabinet to raise dispenser to a height of 12" (305mm).
3. Place dispenser in counter onto support blocks.
4. Attach adjustable legs to dispenser.
5. Remove support blocks and lower dispenser feet to floor.
6. Adjust legs for 1/8" (4mm) clearance between dispenser lip and countertop to verify there is no load on flange.
7. Apply a bead approximately 1/4" (6mm) in diameter of NSF-listed silicone sealant (Dow Corning RTV-732 or
equivalent) around perimeter of dispenser where it meets counter. Smooth sealant to a 1/8" (4mm) radius.
8. Install a PVC drain line with at least a 1/4" per foot (20mm per 1m) slope. Insulate drain line to prevent
condensation.
Note:
Do not apply excessive heat if any sweating of fittings is necessary. Heat conduction through metal may
melt threads in plastic drain.
Do not reduce drain line size or tie drains together.
9. Make electrical connections in accordance with applicable wiring diagrams provided. Provide disconnects within
10 ft (3m) of dispenser and icemaker for servicing.

Field wiring diagrams
Note: Field wiring diagrams are intended to aid electricians or technicians in understanding how equipment
works. All field wiring must be installed in accordance with all local and NEC codes.

Connecting beverage lines
1. Connect syrup and water lines. Non-carbonated water line will be labeled “water”. Syrup lines are numbered
and correspond to the valves as shown in drawing(s) below. Valve one is always next to ice tower.
2. The center 4 valves are pre-plumbed to both carbonated and non-carbonated water lines with the
™
QuickCARB beverage manifold. Valves can be individually changed from a carbonated to a non-carbonated
flavor with the flip of a lever (see below).
3. Clean and sanitize beverage lines according to cleaning instructions.

Installing optional auto-fill icemaker kit(s)
Correct installation of Satellite-fill icemaker(s) is critical to proper performance of icemaker. Refer to installation
manual packed with icemaker for important details on ice transport tube run, ventilation requirements and other
installation requirements. Failure to comply with instructions may void warranty.
To start and operate dispenser
1. Follow detailed cleaning instructions in service manual before operating dispenser.
2. On units with Follett integral ice water bath beverage cooling (“B” models) only, slowly pour water into ice
water bath area to fill empty bath and submerge coils. Coils are submerged when water starts to flow out
overflow drain. DO NOT SPLASH WATER ON ELECTRICAL BOX. Once filled with water, add ice to bath
until ice covers top of water bath.
3. For manual load units, remove front drain pan or rear lid and fill storage area with approved ice.
Note: Follett manual load dispensers 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. For ice compatibility questions, please call Follett customer service at (800) 523-9361
or (610) 252-7301.
4. Turn power switch located on dispenser control box to ON position.
5. For automatic fill units, follow detailed instructions in icemaker installation section of installation manual, then
turn icemaker (bin signal) switch(es) located on dispenser control box to ON position and begin to make ice.
6. When dispenser has at least 6" (153mm) of ice in storage area, test operation.
10
Operation
How the dispenser works
Follett’s dispensers may be fed by Follett Satellite-fill icemakers or manually loaded (using ice from another
source).
In all models, ice is stored below the counter in the dispenser storage area. When the dispense lever or button is
pushed, the dispense motors are 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 units used with an optional icemaker accessory, ice is manufactured remotely and may be located up to 20 ft
(
away from the dispenser. Extruded ice is transported through a tube and pushed to the storage compartment
of the dispenser. When the bin is filled, a bin thermostat shuts the icemaker off to avoid overfilling the bin. The
icemaker will restart after 20 minutes if the bin is calling for ice.
Units with integral ice water bath beverage cooling are equipped with a water bath timer circuit that activates the
water bath pump for 35 minutes when ice lever or button is activated, or when the ice water bath warms up and
calls for more ice.

Dispenser troubleshooting guide
Before calling for service
1. Check that ice is in the dispenser and that congealed cubes are not causing a jam.
2. Check that circuit breaker and switches are in ON position.
3. Check that drain pan and top are on securely. If ajar, dispenser will not operate. When the top is off, auger
does not operate, even though the solenoids do (page 18).
4. Check that all drains are clear.
Note: For units equipped with Follett Chewblet auto-fill icemaker kit(s), see Icemaker Operation and Service
Manual for service and troubleshooting information.
Possible cause
Solution
Symptom
1. Power switch faulty or in OFF

Water bath circuit board operation
The temperature sensor is hard wired directly to the circuit board. The water bath circuit board operates on 24
volts AC. The bath pump will run for 35 minutes whenever ice is dispensed or the bath calls for ice.
Optimal beverage temperature is controlled by the circuit board located in the electrical box. The board monitors
the water bath temperature and holds it to a factory setting. When the Red LED is ON, the bath solenoid, auger
motor, wheel motor and bath pump are energized. Ice will be dispensed into the water bath for 12 seconds, then
stop for 60 seconds. The pump will stay energized, and the circuit board will then monitor the water temperature.
If it is below the set point, the Green LED will come on, the Red LED light will go off, and ice will not dispense
into the water bath. If the temperature of the bath is determined to be above the set point, the Red LED will
remain on. The circuit board has a delay of 60 seconds before more ice is dispensed into the water bath.
LED indicators:
Green – the water bath is at the set temperature.
Red – the bath temperature is above the set temperature and the bath is calling for ice.
Flashing LED indicators:
Flashing Red and Green – the circuit board has gone into an error mode:
Alternate flashing – circuit board has power and is waiting for hopper cover and dispenser top to be
replaced.
Simultaneous flashing – the water bath did not reach set temperature in 40 minutes. Reset this error
mode by turning power off, removing top lid, drain pan or rear lid.
