  • Page 11 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.

  • Page 13 Follett recommends sanitizing the pressurized water lines prior to cleaning the ice machine/dispenser. Follett offers two kits: order P/N 01089572 when a Follett filter system with a pre-filter bowl is present, or P/N 01089580 when a Follett filter system is not present. Follow the instructions provided with the respective kits to sanitize the pressurized water lines immediately before cleaning the ice machine/dispenser.
  • Page 14 § [OPTIONAL] Nu-Calgon IMS-III no-rinse sanitizer (P/N 00979674 – 16 fl oz. bottle) SafeCLEAN Plus Solution: Follow the directions on the SafeCLEAN Plus packaging to mix 1 gal. (3.8 L) of Follett SafeCLEAN Plus solution. Use 100 F (38 C) water.
  • Page 15 Ice Machine and Dispenser Cleaning procedure Note: Check drains and drain cup to ensure they are open and flowing freely. 1. Remove front cover and turn OFF bin signal switch. 2. Dispense all ice from storage hopper and discard. 3. Remove top of machine and hopper lid. 4.
  • Page 16 [OPTIONAL] Finish cleaning – No-rinse sanitizing with Nu-Calgon IMS-III 10. Press CLEAN switch. The MAINTENANCE light will turn on and the machine will fill and drain three times. Wait for the LOW WATER light to turn on. 20. Remove lid from cleaning cup and fill (about 1.2 quarts) until sanitizing solution overflows from the ice transport tube into the hopper.
  • Page 17 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.
  • Page 18 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.
  • Page 19 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 Fig. 16 (for panel removal instructions see page 11). 2.
  • Page 20 A soft error can either be automatically reset should the condition rectify, or if power is cycled. Should an error occur, consult the troubleshooting guide in this manual or a Follett service technician.
  • Page 21 Wiring diagram GRN/YEL 53 12CI414A, 12HI414A...
  • Page 22 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 3 After the initial high current draw drops off, the gearmotor start relay contacts open, dropping out the start winding. The condenser fan output (P3) comes on 0.5 seconds later. Optional in Certain Compressor Models WHITE High Pressure Compressor...
  • Page 25 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 winding is energized through the run capacitor, and through the start capacitor and the normally closed contacts of the start relay.
  • Page 26 Normal operation – Stage 5 As the compressor comes up to normal running speed, its start winding generates a voltage potential across the relay’s coil. This energizes the coil to open the contact and drop out the start capacitor. The ice machine is now in a normal ice making mode. The ice machine will produce ice until the bin level control in the ice dispenser is satisfied.
  • Page 27 Normal operation – Stage 6 Once the bin thermostat control opens, the LOW BIN LED goes out. After a 10 second delay the compressor and gearmotor outputs turn off, the MAKING ICE LED goes out and the TIME DELAY LED comes on. Optional in Certain Compressor Models WHITE...
  • Page 28 Normal operation – Stage 7 The fan motor continues for 10 minutes before shutting off. The TIME DELAY LED remains on for 20 minutes. The ice machine will not start while the TIME DELAY LED is on. To restart the ice machine for troubleshooting purposes, depress the reset button to clear the control board.
  • Page 29 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.
  • Page 30 Self-flushing (when enabled) At the completion of the 20 minute time delay, the machine checks for a cumulative one hour of ice making time since the last off-cycle flush. If the cumulative ice making time exceeds one hour, the machine will energize the drain valve P19 for 60 seconds to drain the evaporator.
  • Page 31 Diagnostic stages High gearmotor amps – Stage 1 The HI AMPS error and TIME DELAY LEDs are on indicating that the control board has sensed an over-torque condition at the P4 terminal (more than 3 amps from the gearmotor) or no current draw (0A) and shut the ice machine down (strike one).
  • Page 32 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 33 High gearmotor amps – Stage 3 If a second occurrence happens during the 60 minute monitoring period, the HI AMPS LED will come on again and shut the machine down (strike two). The HI AMPS LED (without the TIME DELAY LED) will indicate to the technician that two consecutive over-torque situations have occurred.
  • Page 34 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 35 High refrigerant pressure Should the refrigeration discharge 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 detects the contacts closed, the machine will resume normal operation.

It is the responsibility of the technician to ensure that these requirements are met. Refrigeration cycle high pressure switch...
  • Page 37 § 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.
  • Page 38 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.
  • Page 39 SensorSAFE model troubleshooting guide Problem Indicators Corrective Action Does not dispense ice. 1. Power switch off or faulty. 1. Turn on or replace the defective switch. 2.
