Welcome to Follett
Follett equipment enjoys 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 [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 ling
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 rst.
Ice is slippery. Maintain counters and oors 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, ake, 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 [phone].

Installation
Installing dispenser in counter
Note: All dispensers must be supported from below with supplied 6" – 9" (153 – 229 mm) adjustable leg accessory,
or equivalent. Do not hang dispenser on ange.
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" (305 mm).
3. Place dispenser in counter onto support blocks.
4. Attach adjustable legs to dispenser.
5. Remove support blocks and lower dispenser feet to oor.
6. Adjust legs for 1/8" (4 mm) clearance between dispenser lip and countertop to verify there is no load on ange.
7. Apply a bead approximately 1/4" (6 mm) 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" (4 mm) radius.
8. Install a PVC drain line with at least a 1/4" per foot (20 mm per 1 m) slope. Insulate drain line to prevent
condensation.
Note: Do not apply excessive heat if any sweating of ttings 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 (3 m) of dispenser and ice machine for servicing.

Installing optional auto-ll ice machine kit(s)
Correct installation of RIDE™model ice machine(s) is critical to proper performance of the ice machine. Refer to
installation manual packed with ice machine 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 ll 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, ake, 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
[phone].
3. Turn power switch located on dispenser control box to ON position.
4. For automatic ll units, follow detailed instructions in ice machine installation section of installation manual,
then turn ice machine (bin signal) switch(es) located on dispenser control box to ON position and begin to
make ice.
5. When dispenser has at least 6" (153 mm) of ice in storage area, test operation.

Operation
How the dispenser works
Follett’s dispensers are available in automatic load
congurations, fed from one or two Follett RIDE
model ice machines or manual load congurations
(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 RIDE model ice machines.
These ice machines may be located up to 20 ft (6
m) away from the dispenser. Extruded ice is
transported through a tube and pushed to the
storage compartment of the dispenser. When the
bin is lled, a bin thermostat shuts the ice machine
off to avoid overlling of the bin. The ice machine
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 (30 ml) bleach with 2 gal (8 L) hot water.
Solution B: Combine 1/4 oz (7 ml) bleach with 2 gal (8 L) hot water.
Note: Cleaning solutions temperature must be at 75 – 125 F (24 to 52 C)
Recommended cleaning prior to start up
Cleaning ice storage area before use
1. Refer to disassembly instructions (see Service section) and remove dispense wheel from ice storage area.
2. Remove auger, auger tube and dispense mechanism.
3. Wipe all components and ice storage area with cleaning Solution A.
4. Rinse all components and ice storage area thoroughly with clear, potable water.
5. Wipe all components and ice storage area with sanitizing Solution B.

Recommended daily dispenser cleaning
1. Remove all debris from drain pan.
2. Pour 1 gallon (4 L) hot water into drain pan to keep drain lines clear.
Recommended weekly dispenser cleaning
1. Remove drain pan and grille and wash with Solution A. Rinse thoroughly.
2. Pour a solution of one cup (8 oz/237 ml) household bleach mixed with one gallon (3.8 L) hot water into
drain pan to help prevent algae growth in drain lines.
Recommended quarterly dispenser cleaning
1. Remove top from dispenser and turn power switch to OFF position.
2. Remove ice from storage area.

Putting unit back in service after quarterly cleaning
1. Reassemble components.
2. For manual load units, ll unit with an approved ice (see important cautions on page 4).
3. For automatic load units with MC400A/W (R404A refrigerant) ice machines, turn bin signal switch(es) and
dispenser power switch to ON position and allow storage area to ll.
4. Dispense and discard all ice, verifying dispenser is functioning properly.
Recommended quarterly cleaning of optional ice machine.
Units equipped with optional ice machines require cleaning of ice machine system at least every six months, and
more often if local water conditions dictate. Failure to clean ice machine system will result in decreased
performance and potential damage to ice machine. Refer to Ice machine Installation, Operation and Service
Manual.
