  • Page 11 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 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/descaling and sanitizing the ice machine/dispenser .
  • Page 14 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 or IMS-III Sanitizer (P/N 00979674) .
  • Page 15 8. While ice machine is cleaning/descaling, clean dispenser as follows: a . Remove center thumbscrew, locking plate, two wingnuts and backing plate from front of storage hopper . b . Remove stud assembly, baffle, wheel, and any remaining ice . c .
  • Page 16 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 17 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 18 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 12) .

  • Page 24 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 25 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 26 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 27 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 28 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 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 31 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 32 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 .

  • Page 34 § 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 35 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.
