User information

How the dispenser works

Follett’s 12 series automatic-load ice and water dispensers are equipped with Follett’s 181kg (400 lb)/day icemaker. 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 icemaker 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 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.

Cleaning and sanitizing procedures

Solution A: Prepare cleaning solution (200 ppm of available

chlorine content) of Ecolab Mikro-chlor Cleaner or equal chlorinated detergent. Solution temperature must be 24°C – 52°C (75°F – 125°F).

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

be 24°C – 52°C (75°F – 125°F).

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

Icemaker cleaning & sanitizing

Preventive maintenance

Periodic cleaning of Follett’s icemaker system is required to ensure peak performance and delivery of clean, sanitary ice. The recommended cleaning procedures which follow should be performed at least as frequently as recommended below and more often if environmental conditions dictate.

Cleaning of the condenser can usually be performed by facility personnel. Cleaning of the icemaker system in most cases should be performed by your facility’s 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.

Cleaning procedures

Recommended monthly cleaning of condenser

1. Use a vacuum cleaner or stiff brush to carefully clean condenser coils of air-cooled icemakers to ensure optimal performance.

2. When reinstalling counter panels in front of remote icemakers, be sure that ventilation louvers line up with condenser air duct.

Recommended semi-annual cleaning of icemaking system

Icemaking system can be cleaned in place without disassembling water system. Cleaning should be performed at least every 6 months, and more often if local water conditions dictate.

1. Disconnect power to icemaker.

2. Remove any icemaker panels required to gain access to water reservoir and electrical control box.

3. Turn compressor switch on electrical box of icemaker to OFF position.

4. Remove water reservoir cover and block up reservoir float or close water supply valve.

5. Drain water from reservoir by releasing evaporator drain line from float reservoir bracket and removing plug

from drain line.

6. Following manufacturer’s instructions, prepare one gallon (3.8L) of Follett SafeCLEAN Ice Machine Cleaner (one 7 oz packet) or equivalent. Solution temperature must be at least 120° F (48.9° C).

Warning: Most ice machine cleaners contain citric or phosphoric acid that can cause skin irritation. Read

caution label on product and follow instructions carefully.

7. Plug drain hose, replace drain line in reservoir bracket and pour part of cleaning solution into reservoir, filling it almost to overflowing.

8. Remove stainless steel compression nozzle and drain lines. Submerge in a cup of cleaning solution while cleaning rest of system. (Flake icemakers have no compression nozzle and drain lines.)

Caution: To avoid potential pitting, do not soak parts in SafeCLEAN for more than 45 minutes.

9. Restore power to icemaker (gearmotor will run; compressor and fan will not).

10. After 15 minutes, turn power OFF; drain solution from reservoir and evaporator.

11. Fill reservoir almost to overflowing with clean, 120° F (48.9° C) water, and drain. Repeat three times.

12. Following manufacturer’s instructions, prepare 1 gallon (3.8L) of 200ppm 5.25% Sodium Hypochlorite solution (mix 1 oz household bleach to 2 gallons water) or equivalent. Solution temperature must be at least 120° F (48.9° C).

13. Rinse compression nozzle in clean water and submerge in a cup of sanitizing solution while following steps 14-19.

14. Connect ice transport tube directly onto evaporator outlet port without compression nozzle.

Note: If bin will not be cleaned at this time, place a large pan in bin storage area to catch ice or connect a

separate ice transport tube to evaporator and divert ice into separate container.

15. Fill reservoir almost to overflowing with sanitizing solution.

16. Restore power to icemaker (gearmotor will run; compressor and fan will not).

17. After 10 minutes, turn compressor switch to ON position.

18. As unit starts to make ice, continue to pour sanitizing solution into reservoir, maintaining level just below reservoir overflow.

19. Continue to make ice with sanitizing solution for 20 minutes.

20. Turn power to icemaker OFF.

21. Disconnect transport tube from evaporator outlet port. Rinse compression nozzle in clean water and reinstall on evaporator outlet. Reconnect transport tube to compression nozzle.

22. Drain any remaining sanitizing solution from evaporator.

23. Fill reservoir almost to overflowing with clean, 120° F (48.9° C) water, and drain. Repeat three times.

24. Unblock float (or open water supply valve) and replace reservoir cover; restore power to icemaker and ensure compressor switch is in ON position. Make ice for at least 15 minutes to flush any remaining solution from system (remote icemakers with long ice transport hoses may take longer to flush out). Discard this and all ice made during sanitizing.

25. Inspect evaporator drain pan and drain line and remove any accumulated scale build up.

26. Replace any panels removed prior to cleaning.

Start-up following cleaning

1. Clean and sanitize ice storage area of dispenser in accordance with instructions above before making ice.

2. Turn icemaker on and begin to make ice (icemaker should start immediately with power and bin signal supplied).

3. After approximately 30 minutes, test dispenser for proper dispensing.

Service

Important preliminary information

Follett’s icemaker 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 icemaker, 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 no components being serviced are energized.

The icemaking process

The Follett icemaker 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 float valve. This valve also shuts off the water supply when the icemaker is not running.

When the icemaker is running, a layer of ice forms on the interior surface of the evaporator. This ice is continuously removed by a 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 icemaker controls the normal operation of the icemaker and monitors gearmotor torque on an ongoing basis. This control board will shut down the icemaker 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 icemaker.

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).

2. Remove electrical box cover.

3. Pull electrical box toward front of unit.

randomly-generated infrared signal is emitted, reflected 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

Icemaker operational and diagnostic sequences

The wiring diagrams that follow illustrate the circuitry of Follett icemakers 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 closed in ON position.

• Bin signal is 16V DC.

• 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, completing the bin signal circuit 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 float reservoir checks for water in the reservoir. The bin empty LED (B-E), and power LED (PWR) will be on.

Normal operation – Stage 2

The water sensor verifies water in the float 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 gearmotor is started through a current style relay that is pulled in by the initial high current draw of the run winding. The compressor is started with the start winding being energized through the normally closed contacts of the potential relay, starting capacitor, and the run capacitor. The PWR, BE and WTR LED remain on.

Refrigeration system

Important: All service on refrigeration system must be performed in accordance with all federal, state and

local laws that pertain to the use of refrigerants. It is the responsibility of the technician to ensure that these requirements are met.

Icemaker charge specifications

Model Charge Refrigerant type

C/E12CI400A, C/E12HI400A (air-cooled) 540g (19 oz) R404A

Recharging of unit at other than factory specifications will void icemaker warranty.

Refrigerant replacement requirements

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 noncondensibles 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.

Ambients Minimum Maximum

Air temperature1 10˚C/50˚F 37.8˚C/100˚F Water temperature2 4.4˚C/40˚F 32.2˚C/90˚F

Ambient air temperature is measured at the air-cooled condenser coil inlet.

Ambient water temperature is measured in the icemaker float reservoir.

Ice capacity test

Icemaker production capacity can only be determined by weighing ice produced in a specific time period.

1. Remove top panel and hopper lid of unit.

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

3. Run icemaker 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 22).
