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 installation of the dispenser.
Should you have any questions or require technical assistance at any point, please call our technical service
group toll free at [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
filing 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.
U300BR400A
Condenser type – A = air-cooled, W = water-cooled
Remote icemaker(s) capacity and refrigerant – 400 = 400 lbs (181kg)/day, R404A

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 first be disconnected.
•Follett manual load dispensers can accommodate most cube/cubelet ices up to 1" square and
compressed nugget ice. Nugget, 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. For ice compatibility questions, please call Follett customer service
at [phone] 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.

All units
1. Make counter cut-out in accordance with instructions on page 8.
2. If not using legs, block up area below counter cut-out to support dispenser.
Procedure for dispensers that will be dropped into a four-sided cut-out:
3. Center collar over counter cut-out opening.
4. If dispenser is equipped with an icemaker, disconnect ice transport tube from its bracket in storage area of
dispenser (if tube enters opposite from tower).
Note: Since this tube must be reinstalled in bracket after dispenser is dropped into counter, note how tube is
held by bracket tabs before disconnecting.
5. Carefully lower dispenser into counter cut-out as described on page 8, adjusting height of dispenser from
below until dispenser flange rests flush on collar and is supported by legs or blocks.
Procedure for dispensers that will be slid into a three-sided cut-out:
3. Slide collar over bottom of dispenser and hold against dispenser counter flange.
4. Carefully slide dispenser into position, keeping ice transport tube clear of counter supports.
5. Adjust height of dispenser from below until dispenser flange rests flush on collar and is supported by legs or
blocks.
All units
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 collar and smooth sealant to a 1/8" (4mm) radius.
7. Proceed with electrical, plumbing (and ice tube connections on automatic load units) as described beginning
on page 8.
If dispenser is to be installed in a 34" (864mm) high counter for ADA compliance, a
.9" (23mm) stainless steel “collar” must be installed between dispenser and counter
to provide necessary clearance. Standard 36" (915mm) counters do not require this
accessory piece. If you need this collar and it was not included with dispenser,
please call Follett to obtain it.
!
All U300/UD300 dispensers must be installed level in both directions to ensure
proper operation and must be supported from below with supplied 6" (153mm) legs,
or with channels installed at site. Do not hang dispenser on flange. These
dispensers weigh approximately 325 lbs (147kg). Use care when maneuvering unit
into position.
!

Installing U300/UD300 series dispenser in counter
1. After determining that the dispenser location will meet all requirements detailed in this manual, cut counter for
slide-in or drop-in installation as shown in drawings below. Shaded area on drawings depicts slide in from rear
of counter, however dispensers may be slid into counter from any side.
2. If legs will be used, carefully block up dispenser and install set of 6" (153mm) legs.
3. For slide-in installations, carefully slide dispenser into position.
4. For drop-in installations only, rig dispenser for hoisting with a mechanical lift and carefully lower dispenser
into counter until dispenser rests on support blocks or legs. USE SPREADER BARS TO KEEP HOISTING
ROPES AWAY FROM UPPER SECTION OF DISPENSER. DO NOT HOIST BY TOWER OR RAIL
SECTION! MUST REMOVE HANDLE TO FIT IN COUNTER.
5. Shim support members or adjust legs until dispenser flange rests lightly on 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 hard drain lines for all drains, maintaining at least a 1/4" per foot slope (6mm per 304mm run)
and insulate lines to prevent condensation.
8. Make electrical connections in accordance with applicable wiring diagrams on page 6 and chart on page 5, as
well as NEC and local codes. Provide disconnects within 10 ft (3m) of dispenser and icemaker for service
purposes.
