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 at (800) 523-9361 or (610) 252-7301.

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 U155 series.

U155BR400AXR

Ice dispense chute location – R = right side, L = left side

Presence of an X = 10 soda valves

B = beverage bath equipped. Absence of a B = no integral beverage cooling

Approximate manual load storage capacity in lbs

Dispenser con guration – U = undercounter

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 (800) 523-9361 or (610) 252-7301.

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" (4mm) clearance between dispenser lip and countertop to verify there is no load on  ange.

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  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 (3m) of dispenser and icemaker for servicing.

Connecting beverage lines

8910

1. Connect syrup and water lines. Non-carbonated water line will be labeled “water”. Syrup lines are numbered and correspond to the valves as shown in drawing(s) below. Valve one is always next to ice tower.

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

Valve position #1 is always next to ice

tower. Right-hand unit shown.

Installing optional icemaker

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 up and operate dispenser

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

2. On units with Follett integral ice water bath beverage cooling (“B” models) only, slowly pour water into ice water bath area to  ll empty bath and submerge coils. Coils are submerged when water starts to  ow out over ow drain. DO NOT SPLASH WATER ON ELECTRICAL BOX. Once  lled with water, add ice to bath until ice covers top of waterbath.

3. 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 (800) 523-9361 or (610) 252-7301.

4. Turn power switch located on dispenser control box to ON position.

5. For automatic  ll 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.

6. When dispenser has at least 6" (153mm) of ice in storage area, test operation.

Page 10

Operation

How the dispenser works

Follett’s dispensers are available in automatic load con gurations, fed from one or two Follett remote icemakers 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 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  lled, a bin thermostat shuts the icemaker off to avoid over lling of the bin. The icemaker will restart after 20 minutes if the bin is calling for ice.

Units with integral ice water bath beverage cooling are equipped with a waterbath timer circuit that activates the waterbath pump for 35 minutes when ice lever or button is activated, or when the ice water bath warms up and calls for more 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.

Waterbath circuit board operation

The temperature sensor is hard wired directly to the circuit board. The waterbath circuit board operates on 24 volts AC. The bath pump will run for 35 minutes whenever ice is dispensed or the bath calls for ice.

Optimal beverage temperature is controlled by the circuit board located in the electrical box. The board monitors the waterbath temperature and holds it to a factory setting. When the Red LED is ON, the bath solenoid, auger motor, wheel motor and bath pump are energized. Ice will be dispensed into the waterbath for 12 seconds, then stop for 60 seconds. The pump will stay energized, and the circuit board will then monitor the water temperature. If it is below the set point, the Green LED will come on, the Red LED light will go off, and ice will not dispense into the waterbath. If the temperature of the bath is determined to be above the set point, the Red LED will remain on. The circuit board has a delay of 60 seconds before more ice is dispensed into the waterbath.

LED indicators:

Green – the waterbath is at the set temperature. Red – the bath temperature is above the set temperature and the bath is calling for ice.

Flashing LED indicators:

Flashing Red and Green – the circuit board has gone into an error mode: Alternate  ashing – circuit board has power and is waiting for hopper cover and dispenser top to be replaced. Simultaneous  ashing – the waterbath did not reach set temperature in 40 minutes. Reset this error mode by turning power off, removing top lid, drain pan or rear lid.
