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, [phone] or
(888) 2-FOLLETT or [phone].
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 VU155 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
[phone] or (888) 2-FOLLETT or [phone].

Installation
Installing dispenser in counter
Note: All dispensers must be supported from below with supplied 6" – 9" (153 – 229mm) adjustable leg accessory,
or equivalent. Do not hang dispenser on flange.
All dispensers must be installed level in both directions to ensure proper operation.
1. Check that dispenser location meets all requirements in this manual and cut counter as shown.
Plan View
counter cut-out
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.

Installing optional auto-fill icemaker kit(s)
Correct installation of remote 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. 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 [phone]
or (888) 2-FOLLETT or [phone].
3. Turn power switch located on dispenser control box to ON position.
4. 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.
5. When dispenser has at least 6" (153mm) of ice in storage area, test operation.

Operation
How the dispenser works
Follett’s dispensers are available in automatic
load configurations, fed from one or two Follett
remote icemakers or manual load configurations
(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 automatic load units, ice is manufactured in
either one or two Follett remote icemakers. These
icemakers may be located up to 20 ft (6m) 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 of the bin. The icemaker will
restart after 20 minutes if the bin is calling for ice.
Cleaning
Using solutions below, clean and sanitize storage area and beverage lines before starting unit and on a routine
basis as noted below.
Note: Always disconnect power before cleaning dispenser.
Do not run plastic parts through a dishwasher.
Solution A: Combine 1 oz (250ml) bleach with 2 gal (8L) hot water or use Ecolab Mikro-chlor Cleaner
per manufacturers instructions.
Solution B: Combine 1/4 oz (50ml) bleach with 2 gal (8L) hot water or use Ecolab Mikro-chlor Cleaner
per manufacturers instructions.
Note: Cleaning solutions temperature must be at 75˚ – 125˚F (24˚ to 52˚C)

dispenser power switch to ON position and allow storage area to fill.
4. Dispense and discard all ice, verifying dispenser is functioning properly.
Recommended quarterly cleaning of optional icemaker.
Units equipped with optional icemakers require cleaning of icemaker system at least every six months, and more
