How the dispenser works

Follett’s 25 and 50 automatic load ice and water dispensers receive ice from Follett’s 400 lb (181kg)/day icemaker located in the dispenser base, in the cabinet top or in a remote location up to 20 ft (6m) away. Ice produced is stored in the bin section of the dispenser. When the dispense lever is pushed, the wheel motor is energized, causing the wheel to turn. This moves ice to the dispense chute where it drops by gravity into the container held below the chute.

In Follett’s continuous icemaking process, water freezes to the inside walls of the stainless steel evaporator. A rotating stainless steel auger carries the ice to the top of the evaporator where it is compressed and extruded through a nozzle on the outlet port. The ice is then pushed through a tube to the dispenser bin. When the storage area is full, a bin stat opens and shuts the icemaker off to avoid over-filling of the bin. The icemaker will restart after 20 minutes if the bin is calling for ice.

How the SensorSAFE accessory works

Follett’s SensorSAFE accessory maximizes sanitation and minimizes the possibility of cross-contamination by eliminating physical contact between the cup or container and dispenser. Sensors in the panel use reflected infrared light to detect the presence of the container and send a signal to a control board which then activates the appropriate components for ice or water dispensing.

The SensorSAFE package includes a cleaning switch under the left side of the front cover which temporarily shuts off dispensing to allow cleaning of the panel and lenses. If the switch is not turned back on after cleaning, the dispenser automatically resets after two minutes for normal operation.

SensorSAFE also includes a time limit safety feature which automatically stops ice dispensing after one minute of continuous dispensing. Dispensing can be resumed by moving the container away from the dispenser and returning it to the activation zone.

How the chilled water accessory works

Follett’s chilled water accessory uses ice from the dispenser’s storage hopper to chill incoming water supplied to the water station. The water chiller assembly is located in the dispenser cabinet under the storage hopper. As ice is dispensed it is automatically fed into the water chiller assembly to chill the water coil inside the assembly.

Cleaning and sanitizing procedures

Solution A: Prepare cleaning solution (200 ppm of available chlorine content) of Ecolab Mikro-chlor Cleaner or equal

Solution B: Prepare sanitizing solution (50 ppm of available chlorine content) of Ecolab Mikro-chlor Cleaner or equal

Follett recommends the periodic cleaning schedule on page 17 to ensure the quality of ice provided. Use only recommended cleaning solutions. Do not use solvents, abrasive cleaners, metal scrapers or sharp objects.

Service information

Wiring diagrams

How unit works — lever models

The dispense wheel motor is energized through the power and ice dispense switches. The water solenoid valve is energized through the power and water dispense switches. The icemaker receives the bin signal through the power switch, the normally closed bin thermostat and the icemaker switch. When the bin level thermostat is calling for ice, a 115v bin signal is applied to the bin signal terminals on the icemaker circuit board. When ice builds up around the bin thermostat, the contacts open, cutting the bin signal to the icemaker.

How unit works — SensorSAFE models

SensorSAFE models provide “touchless” ice and water dispensing. When a container is placed within the actuation zone below the ice or water chute on SensorSAFE dispenser models, an infrared signal reflects off the container and is detected by the sensor. The sensor then sends a signal to the control board to activate the appropriate components to dispense ice or water. LEDs on the board indicate when the board is receiving a signal from the sensors.

A safety, shut-off feature automatically shuts off dispensing after one minute of continuous activation. Dispensing can be restarted by moving the container away and then returning it to the actuation zone.

Dispensing can be temporarily suspended for cleaning by depressing and releasing the clean switch, located under the left side of the top front cover. Depressing and releasing the button a second time will return the dispenser to normal operating state. If the clean switch is not depressed a second time, the dispenser will automatically resume normal dispense operation (CLN LED goes out) after two minutes. An LED on the control board will light to indicate that the dispensing has been suspended by activation of the clean switch.
