Before you begin After uncrating and removing all packing material, inspect the equipment for concealed shipping damage. If damage is found, notify the shipper immediately and contact Follett Corporation so that we can help in the filing of a claim, if necessary.
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. §...
Installing countertop dispensers with legs accessory (P/N AF10LBLEGS) CAUTION! § Do not tilt any 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.

User information How the dispenser works Follett’s 12 series automatic-load ice and water dispensers are equipped with Follett’s 425 lb (193 kg)/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.
Panel removal Fig. 10 Fig. 11 Top cover: Lift cover up and off Velcro strips. Front cover: Pull bottom of cover, then lift cover up and forward to unhook from keyhole slots. Fig. 12 Fig. 13 Splash panel: Remove 4 screws. Pull out bottom Side panels: Remove screw located on lower rear of panel to allow top to slide out from under hopper side.
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.
Page 12
Cleaning Solution: Mix cleaning solution of 1 gal. (3.8 L) 100 F (38 C) water and 7 oz (198 g) (one 7 oz packet) of Follett SafeCLEAN ice machine cleaner/descaler (P/N 00132001). Sanitizing Solution: Mix a sanitizing solution of 1 gal. (3.8 L) 100 F (38 C) water and 1.6 oz (47 ml) Nu-Calgon IMS-II Sanitizer (P/N 00979674).
Sanitizing procedure 10. Press CLEAN switch. The MAINTENANCE light and LOW WATER light will turn on. 11. Fill cleaning cup with sanitizing solution until it overflows from the ice transport tube into the hopper. Place lid back on cup. Save remainder of sanitizing solution. 12.
Service Ice machine operation (all models) Follett’s ice machine consists of four distinct functional systems: § Harvesting system § Refrigeration system § Water system § Electrical control 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.

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.
Page 23
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.
Page 24
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.
Page 25
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.
Page 26
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 is off, the ice machine will go through the normal start-up sequence when the bin level control signals the control board for ice.

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.
Page 29
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.
Page 30
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.

§ Recharging of unit at other than factory specifications will void ice machine 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.
Dispenser troubleshooting CAUTION! § Disconnect power to unit before putting hands or arms in storage area or attempting any repair or service to equipment. Before calling for service 1. Check that no ice is in the dispenser bin area. 2. Check that congealed ice is not causing a jam 3.
