  • Page 7: User Information

    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 8: Cleaning

    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 22: Ice Machine Operational And Diagnostic Sequences

    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 1 - 220 V 60 Hz The 220 V 60 Hz is identical to the 230 V 50 Hz EXCEPT that the compressor output and neutral are reversed, as shown in the diagram below. The remaining Stages show only the 230 V 50 Hz applications. High Pressure Start...
  • 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. T.O.L. High Pressure Switch Compressor Start Relay WHITE Compressor...
  • Page 25 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 26 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 27 Quiet Night™/Sleep cycle The board monitors ice dispensing through a line voltage input to P15. If the ice dispense has not be initiated for more than 5 seconds during the 20 minute time delay, the SLEEP CYCLE LED comes on. The machine will stay off for 12 hours unless 5 seconds of dispensing is seen.

  • Page 28: Diagnostic Stages

    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 3A from the gearmotor) or no current draw (0A) and shut the ice machine down (strike one).
  • Page 29 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 1.8A) or no current draw (0A) 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 30 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 31 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.

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.
