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 U300 series.

Condenser type – A = air-cooled, W = water-cooled

Remote icemaker(s) capacity and refrigerant – 400 = 400 lbs (181kg)/day, R404A

800 = 800 lbs (363kg)/day, R404A
absence of = manual fill unit

K = Integral ice water bath cold carbonator equipped

Approximate manual load storage capacity in lbs

Dispenser configuration – U = undercounter, UD = undercounter dual-sided

U300KR400A

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 servicee 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.

If dispenser is to be installed in a 34" (864mm) high counter for ADA compliance, a .9" (23mm) stainless steel
collar accessory must be installed between dispenser and counter to provide necessary clearance. Standard
36" (915mm) counters do not require this accessory piece.

1. Check that dispenser location meets all requirements in this manual and cut counter as shown.

2. If required, install ADA collar accessory by centering collar on opening.

3. Place support blocks in cabinet tto raise dispenser to a height of 12" (305mm).

4. Place dispenser in counter onto support blocks.

5. Attach adjustable legs to dispenser.

6. Remove support blocks and lower dispenser feet to floor.

7. Adjust legs for 1/8" (4mm) clearance between dispenser lip and countertop to verify there is no load on flange.

8. 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.

9. 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.

10. Install carbonator pump. See instruction enclosed with pump for detailed installation instructions.

11. Make electrical connections in accordance with applicable wiring diagrams provided. Provide disconnects within
10 ft (3m) of dispenser and icemaker for servicing.
