Operation

How the dispenser works

Follett’s dispensers are available in automatic load
configurations, fed from one or two Follett Satellite­fill icemakers or manual load configurations (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 Satellite-fill 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 filled, a bin thermostat shuts the icemaker off
to avoid overfilling 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 water bath timer circuit that
activates the water bath pump for 35 minutes
when ice lever or button is activated, or when the
ice water bath warms up and calls for more ice.

Connecting beverage lines

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. The center 4 valves are pre-plumbed to both carbonated and non-carbonated water lines with the
QuickCARB

™

beverage manifold. Valves can be individually changed from a carbonated to a non-carbonated

flavor with the flip of a lever (see below).

3. Clean and sanitize beverage lines according to cleaning instructions.

Ice movement

Electrical box
Front View

Water bath circuit board operation

The temperature sensor is hard wired directly to the circuit board. The water bath 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 water bath 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 water bath 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 water bath. 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 water
bath.

LED indicators:

Green

– the water bath 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 flashing – circuit board has power and is waiting for hopper cover and dispenser top to be

replaced.
Simultaneous flashing – the water bath did not reach set temperature in 40 minutes. Reset this error
mode by turning power off, removing top lid, drain pan or rear lid.
