Installation Before you begin § All dispensers must be installed level in both directions to ensure proper operation. § Service and ventilation clearances: 6" (15.3 cm) on right side of dispenser, 6" (15.3 cm) at top for ventilation and 12" (30.5 cm) at top recommended for service. § Countertop units installed without legs provide the option of taking utilities out bottom or back of dispenser (on wall mount units and countertop units with legs, utilities exit from back).
Installing countertop dispensers with legs accessory (P/N AF10LBLEGS) CAUTION! § Do not tilt unit further than 30° off vertical plane. § Countertop dispensers that sit on legs (not bolted to counter) can be inadvertently moved. Care should be taken when operating and cleaning to avoid accidents. 1. Carefully tip dispenser back to expose underside and block up in place. 2.
Installing wall mount dispensers CAUTION! § WALL PREPARATION: Wall and fasteners must be of sufficient strength to carry weight of unit (185 lb (83.9 kg). Hardware for this is not included. Notes: § SensorSAFE™ infrared dispensing is standard. 1. Recommended minimum counter depth and mounting height (Fig. 6) ensures that ice will drop into sink. 2. See Fig. 6 for model dimensions. The dimensions include the 0.5" (13 mm) mounting bracket supplied with the unit. 3. Cut utility hole in wall as shown (Fig. 5).

Fig. 12 Fig. 13 Splash panel: Remove 4 screws. Pull out bottom of panel to allow top to slide out from under hopper support lip. Side panels: Remove screws. Lift panel to disengage from back panel, then remove. Note: Before removing right hand side, remove side louver panel by lifting up and pulling forward on panel.
Cleaning and sanitizing Follett ice machines and dispensers, and their associated cleaning and sanitizing procedures, are designed for use with potable water sources. The presence, or suspected presence, of infectious agents may call for additional measures, including the replacement of components and more comprehensive disinfection measures.
Weekly CAUTION! § Do not use solvents, abrasive cleaners, metal scrapers or sharp objects to clean any part of the dispenser. Dispenser drain pan and drain line § Pour 1 gal. (3.8 L) of hot tap water into drain pan to flush drains. Splash panel front, SensorSAFE infrared dispensing 1. Deactivate dispensing by pressing and releasing clean switch located on left side of unit under top front cover. 2. Clean lens and splash panel front using a soft cloth and mild, non-abrasive, non-chlorine based cleaner. 3.
Ice Machine and Dispenser Cleaning procedure Note: Check drains and drain cup to ensure they are open and flowing freely. 1. If ice machine was running recently, ensure that the evaporator is completely free of ice before proceeding. If there is ice in the evaporator, complete steps 2-7 using only hot water to remove the ice then begin Cleaning Procedure again. 2. Remove front cover and turn OFF bin signal switch. 3. Dispense all ice from storage hopper and discard. 4. Remove top of machine and hopper lid.
[OPTIONAL] Finish cleaning – No-rinse sanitizing with Nu-Calgon IMS-III 19. Press CLEAN switch. The MAINTENANCE light will turn on and the machine will drain. Wait for the LOW WATER light to turn on. 20. Remove lid from cleaning cup and fill (about 1 quart) until sanitizing solution overflows from the ice transport tube into the hopper. Place lid back on cup. Save remainder of sanitizing solution. 21.
Service Ice machine operation (all models) Follett’s ice machine consists of four distinct functional systems: § Harvesting system § Water system § Electrical control system § Refrigeration system These four systems work together to accomplish the production and harvesting of ice. A problem in any one of these systems will result in improper operation of the entire ice production cycle.
Water system The water level in the evaporator is controlled by a fill solenoid (Fig. 14) and level detecting sensors. Water sensing rods (Fig. 15) extend down into the reservoir at the end of the evaporator assembly. The system works via electrical conductivity as follows: One of the longest probes is a common. When water is between any of the other probes and the common, the PC board will sense the activation.
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 12). 2. Remove electrical box cover. 3. Pull electrical box toward front of unit. Fig. 16 electrical box electrical cover Electrical system ATTENTION! To prevent circuit breaker overload, wait 15 minutes before restarting this unit.

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 1–8) and non-normal diagnostic sequences showing torque-out for use in troubleshooting are shown. Circuitry notes § Bin signal is contact closure only - DO NOT SUPPLY POWER. Note: The operation stage descriptions that follow are based on the unit containing the split-phase gear motor.
Normal operation – Stage 2 When continuity is seen between B and C, the water valve de-energizes, the AUGER output (P4) comes on along with the MAKING ICE LED. The auger gearmotor’s start windings are energized through a current style start relay that is pulled in by the initial high current draw of the gearmotor. T.O.L.
Normal operation – Stage 4 One second (1 s) after the fan comes on, the COMPRESSOR output comes on. The compressor circuit uses both run and start capacitors along with a potential start relay. The start capacitor in energized through the normally closed contacts of the start relay. T.O.L.
Normal operation – Stage 6 Once the bin thermostat control opens, the LOW BIN LED goes out. After a 10 second delay the compressor output turns off, the MAKING ICE LED goes out and the TIME DELAY LED comes on. T.O.L.
Normal operation – Stage 8 When the dwell time of 20 minutes has expired, the TIME DELAY LED goes off. If 5 seconds of ice has been dispensed and the SLEEP CYCLE LED (Symphony Plus only) is off, the ice machine will go through the normal start-up sequence when the bin level control signals the control board for ice. T.O.L.
T.O.L.
High gearmotor amps – Stage 2 If the restart is successful the board will continue to monitor the current draw on P4 for 60 minutes looking for a second high amps (above 3A) occurrence. If the ice machine runs without problems for 60 minutes and no additional torque errors occur, the ice machine will continue normal operation. T.O.L.
Loss of water During operation, the water level cycles between the normal low (D) and normal high (C) water probes - the fill valve (P21) cycling on and off. If continuity is not detected between the common probe (B) and normal low (D) within 10 seconds, the LOW WATER and TIME DELAY LEDs will come on and the machine will shut down for the one hour time delay period. After the time delay, the fill valve will re-energize and wait for continuity between the common probe and normal high before restarting.
High refrigerant pressure Should the refrigeration pressure rise above 425 psi, the high pressure switch contacts will open. The board sees the open circuit and the HIGH PRESSURE and TIME DELAY LEDs will come on, the machine shuts down. After the one hour time delay, the machine will attempt to restart. If the pressure has fallen below the reset point of 295 psi and the board see the contacts closed, the machine will resume normal operation.
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.
