User information

How the dispenser works

Follett’s 12 series automatic-load ice and water dispensers are equipped with Follett’s 400 lb (181kg)/day ice machine. In the continuous icemaking process, water freezes to the inside wall of the evaporator. A rotating stainless steel auger carries the ice to the top of the evaporator where it is compressed and extruded through an outlet port. The ice is then pushed through a tube to the storage hopper. When the hopper is full, a bin thermostat opens and shuts the ice machine off. When the dispense mechanism is activated, a dispense motor is turned on, causing the wheel to turn. This moves ice to the dispense chute where it drops by gravity into the container held below the chute.

How SensorSAFE infrared dispensing works

Follett’s SensorSAFE infrared dispensing maximizes sanitation and minimizes the possibility of crosscontamination by eliminating physical contact between the cup or container and dispenser. Sensors in the panel use re ected 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 infrared dispensing 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 infrared dispensing 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.

Cleaning/descaling and sanitizing

Periodic cleaning/descaling and sanitizing of Follett’s ice and water dispenser and ice machine system is required to ensure peak performance and delivery of clean, sanitary ice. The recommended cleaning procedures that follow should be performed at least as frequently as recommended and more often if environmental conditions dictate.

Cleaning of the condenser can usually be performed by facility personnel. Cleaning/descaling and sanitizing of the ice machine system should be performed by your facility’s trained maintenance staff or a Follett authorized service agent. Regardless of who performs the cleaning, it is the operator’s responsibility to see that this cleaning is performed according to the schedule below. Service problems resulting from lack of preventive maintenance will not be covered under the Follett warranty.

Service

Important preliminary information

Follett’s ice machine consists of four distinct functional systems.

§ Refrigeration system

§ Water system

§ Harvesting system

§ Electrical control system

These four systems work together to accomplish the production and harvesting of ice. A problem in any one of these system areas will result in improper operation of the entire ice production cycle. When troubleshooting the ice machine, it is important to analyze the entire system operation to determine which system is not functioning properly, then pinpoint the component within that system that is malfunctioning. Determine what corrective action must be taken before making any adjustments or replacing any components.

Note: When performing electrical service, always use a meter to determine whether or not components being

serviced are energized.

The icemaking process

The Follett ice machine uses a stainless steel jacketed evaporator and operates on a continuous freezing cycle. Water is supplied to the evaporator from the water reservoir where the water level is controlled by a  oat valve. This valve also shuts off the water supply when the ice machine is not running.

When the ice machine is running, a layer of ice forms on the interior surface of the evaporator. This ice is continuously removed by a slowly rotating (12 RPM) auger. The auger carries the ice upward into the cavity formed by the top bearing housing and the compression loop, where it is compressed to remove excess water. When the ice reaches the desired hardness it rotates within the cavity and is forced through a discharge port and compression nozzle and into the ice transport tube. The discharge tube and compression nozzle are slightly restricted to further compress the ice and produce the desired high quality. As the formation of ice continues, ice in the transport tube is pushed through the tube to the storage compartment in the ice dispenser or ice storage bin.

A solid state control board located in the electrical box of the ice machine controls the normal operation of the ice machine and monitors gearmotor torque on an ongoing basis. This control board will shut down the ice machine should an over-torque condition occur. It is very important that you familiarize yourself with the operational sequences detailed in this manual before attempting to service the ice machine.

Access to electrical box and control board

The 12 series electrical box has been designed to slide out for easy access to the control board and more convenient troubleshooting.

1. Remove top and front panels of dispenser (for panel removal instructions see page 31).

2. Remove electrical box cover.

3. Pull electrical box toward front of unit.

How the unit works — models with SensorSAFE infrared dispensing

Models with SensorSAFE infrared dispensing provide “touchless” ice and water dispensing. When a container is placed within the actuation zone below the ice or water

chute, an invisible, randomly-generated infrared signal is emitted, re ected off the container and 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 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. The bin signal circuit is completed through the normally closed contacts of the bin thermostat and the bin signal switch. When ice builds up around the bin thermostat,

the contacts open, cutting the bin signal.

Ice machine operational and diagnostic sequences

The wiring diagrams that follow illustrate the circuitry of Follett ice machines used with 12 series ice dispensers. Both normal operation (stages 1 - 6) and non-normal diagnostic sequences showing torque-out (stages 7 - 10) for use in troubleshooting are shown.

Circuitry notes

§ Compressor switch should read open in ON position.

§ Compressor start relay is position sensitive. See label on start relay for proper orientation.

§ Bin signal is 115 V, 60 Hz.

§ Flashing water LED at any time indicates that water signal to board has been lost for more than one second.

§ Ten-second delay: There is a 10 second delay in reaction to loss of water (WTR) or bin (B-E) signals. If signals are not lost for more than 10 seconds, no reaction will occur.

Normal operation – Stage 1

Power is supplied to L1 of the control board. The ice level control in the dispenser is closed and calling for ice, supplying signal voltage to the control board. The control board will now go through the start-up sequence. Less than 30 seconds will elapse as the water sensor located in the  oat reservoir checks for water in the reservoir. The bin empty LED (B-E) and power LED (PWR) will be on.

The water sensor veri es water in the  oat reservoir. The water OK LED (WTR) comes on. At the same time, the gearmotor, compressor and condenser fan motor come on, lighting the drive LED (DR) and compressor LED (C). The high initial current draw of the compressor run winding closes the contacts of the current relay energizing the start winding through the run capacitor. The gearmotor is also started through a current style relay (or start capacitor) that is pulled in by the initial high current draw of the run winding. The PWR, B-E and WTR LED remain on.

After the initial high current draw drops off, the gearmotor start relay contacts open, dropping out the start winding (or start capacitor). As the compressor comes up to normal running speed, the compressor start relay contacts also open, dropping out the start winding of the compressor. The ice machine is now in a normal icemaking mode. The ice machine will begin to produce ice and continue to produce ice until the bin level control in the ice dispenser is satis ed. The PWR, B-E, DR, C and WTR LEDs are all on.

Normal operation – Stage 4

Once the ice level control opens, the B-E LED goes out. After a 10 second delay the compressor LED (C), compressor and fan motor go off. (Should the ice level control not remain open for 10 seconds, the ice machine will continue to run.) The gearmotor continues to run and the DR LED remains lighted for 60 seconds. The purpose of this function is to drive the remaining ice out of the evaporator and to boil off any refrigerant remaining in the evaporator.

1. Non-contaminated refrigerant removed from any Follett refrigeration system can be recycled and

returned to the same system after completing repairs. Recycled refrigerant must be stored in a clean, approved storage container. If additional refrigerant is required, virgin or reclaimed refrigerant that meets ARI standard 700-88 must be used.

2. In the event of system contamination (for example, a compressor burn out, refrigerant leak, presence

of non-condensibles or moisture), the system must be repaired, evacuated and recharged using virgin or reclaimed refrigerant that meets ARI standard 700-88.

3. Follett Corporation does not approve of recovered refrigerants. Improper refrigeration servicing

procedures will void the factory warranty.

Evacuation

Evacuate the system to a level of 500 microns. When the 500 micron level is reached, close valves and both manifold and shut down the vacuum pump. Allow the system to sit for approximately 20 minutes. During this period the system pressure should not rise. If the system pressure rises and stabilizes there is moisture in the system and further evacuation is needed. If the pressure continues to rise check the system for leaks.

Ice capacity test

Ice machine production capacity can only be determined by weighing ice produced in a speci c time period.

1. Remove top panel and hopper lid of unit.

2. Weigh and record weight of container used to catch ice.

3. Run ice machine for at least 15 minutes.

4. Catch ice for 15 or 20 minutes.

5. Weigh harvested ice and record total weight.

6. Subtract weight of container from total weight.

7. Convert fractions of pounds to decimal equivalents (Ex. 6 lbs 8 oz = 6.5 lbs).

8. Calculate production using following formula:

1440 min. x wt. of ice produced = Production capacity/24 hr. period Total test time in minutes

9. Calculated amount per 24 hours should be checked against rated capacity for same ambient and

water temperatures in Ice Production Table (see page 23).
