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 toll-free, [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 U155 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 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 toll-free at (800) 523­9361 or (888) 2-FOLLETT, or [phone].

•

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 recommended cleaning instructions to maintain cleanliness of delivered ice.

Installation

Installing U155 dispenser in counter

1. Check that dispenser location meets all requirements in this manual and cut counter as shown. (NOTE: Different
cut-outs for 8 and 10 valve units!)

2. Block up area below counter cut-out to support dispenser when lowered into place.

3. For automatic load dispensers, disconnect ice transport tube from bracket in storage area of dispenser. (Since this
tube must be reinstalled in bracket after dispenser is dropped into counter, note how tube is held by bracket tabs
before disconnecting.)

4. Carefully lower dispenser into counter until it rests on support blocks.

5. Adjust height from below until dispenser flange rests flush with counter.

6. 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 and smooth sealant to a 1/8" (4mm) radius.

7. Install a hard drain line, maintaining at least a 1/4" per foot (6mm per 30.4cm run) slope, and insulate line to
prevent condensation.

8. Make electrical connections in accordance with applicable wiring diagrams provided, as well as NEC and local
codes. Provide disconnects within 10 ft (3m) of dispenser and icemaker for servicing.

units with up to 8

valves

Counter cut-out

units with 10

All U155 dispensers must be installed level in both directions and supported
from below with 6" - 9" (153 - 229mm) adjustable leg accessory provided, or
channels installed on site. Do NOT hang dispenser on flange.

!

PVC pipe is suggested. Care must be taken in sweating any metal drain pipe
used. Excessive heat applied while sweating metal pipe may melt plastic
fitting on dispenser.

Installing remote icemaker (automatic load units only)

1. Position icemaker in desired location.

2. Push one end of ice transport tube(s) through hole(s) provided in side of dispenser.

3. Route tube into ice tube bracket inside dispenser and engage bracket tabs in holes located in end of ice
transport tube(s). (See drawings below.)

4. Proceed with ice transport tube installation from dispenser to icemaker in compliance with instructions
contained in icemaker installation manual packed with icemaker.

6

Correct installation of remote icemaker(s) is critical to proper performance
of icemaker and dispenser.

Check bin signal on icemaker control board for 24 volt connection. Switch if
necessary.

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 will void warranty.

Connecting beverage lines

1. Connect syrup and water lines, following drawings for appropriate model U155 dispenser. Non-carbonated water line
will be labeled “water”.

2. Clean and sanitize beverage lines in accordance with cleaning instructions that follow.

To start-up and operate dispenser

1. Follow detailed cleaning instructions in service manual before operating dispenser.

2. Follow instructions for beverage line hook-up, and restrictions on ice that can be manually filled into a Follett
dispenser.

3. On units with Follett integral ice-water bath beverage cooling (“B” models) only, slowly pour water into ice-waterbath
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
waterbath.

4. For manual load units, remove front drain pan or rear lid and fill storage area with compatible ice.

5. Turn power switch located on control box to "ON" position.

6. For automatic fill units, follow detailed instructions in icemaker installation section of installation manual, then turn
icemaker (bin signal) switch(es) located on control box to "ON" position and begin to make ice.

7. When dispenser has at least 6" (155mm) of ice in storage area, press "PUSH FOR ICE" lever or button to ensure
that dispenser is operating properly. NOTE: IF ADDITIONAL START-UP INFORMATION IS NEEDED, CALL
FOLLETT CORPORATION AT [phone].

NOTES:

Syrup lines are numbered and correspond to the valves as shown in drawing
above. Valve one is always adjacent to ice tower.

Numbered beverage lines extend out from side of dispenser opposite ice chute.

Valve position #1 is always next to ice

tower. Right-hand unit shown.

7

Follett manual load dispensers can accommodate most cube/cubelet ices up
to 1" square and Follett compressed nugget ice. Crushed, flake, nugget,
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. For questions about ice compatibility, call Follett's customer
service group toll-free at [phone] or (888) 2-FOLLETT, or [phone].
