Welcome to Follett Follett equipment enjoys a well-deserved reputation for excellent performance, long-term reliability and outstanding after-the-sale support. To ensure that this equipment delivers that same degree of service, we ask that you review the installation portion of this manual before beginning to install the unit. Our installation instructions are designed to help you achieve a trouble-free installation.
20mm per 1m run (1/4" per foot) of slope. Ventilation clearances 6" (153mm) on right side of dispenser, 6" (153mm) at top for ventilation and 12" (305mm) at top recommended for service. Note: Do not block right side air intake or top air exhaust.
• Service and ventilation clearances: 153mm (6") on right side of dispenser, 153mm (6") at top for ventilation and 305mm (12") 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 wall mount dispensers Notes: No drain pan is provided since the dispenser is intended to be installed above a sink. (Contact Follett if a drain pan is desired.) SensorSAFE actuation is standard. (Contact Follett if lever actuation is desired. A deeper cabinet will be needed.) Recommended minimum counter depth and mounting height shown on Fig.

How the dispenser works Follett’s 12 series automatic-load ice and water dispensers are equipped with Follett’s 181kg (400 lb)/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.
Cleaning/descaling and sanitizing Periodic cleaning/descaling and sanitizing of Follett’s ice and water dispenser and ice machine system is required to ensure peak performance and delivery of clean, sanitary ice. The recommended cleaning procedures that follow should be performed at least as frequently as recommended and more often if environmental conditions dictate. Cleaning of the condenser can usually be performed by facility personnel.
11. After 15 minutes, turn power OFF; drain solution from reservoir and evaporator. 12. Fill reservoir almost to overfl owing with clean water to rinse. Drain. Repeat two more times. 13. Rinse ice compression nozzle and drain lines in clean water.

ervoir overfl ow. 20. Continue to make ice with Solution B for 20 minutes. 21. Turn power to ice machine OFF. 22. Disconnect ice transport tube from evaporator outlet port. Rinse ice compression nozzle and drain lines in clean water and reinstall on evaporator outlet. Reconnect ice transport tube to ice compression nozzle.
When the ice machine is running, a layer of ice forms on the interior surface of the evaporator. This ice is continuously removed by a rotating (12 RPM) auger. The auger carries the ice upward into the cavity formed by the top bearing housing and the compression loop, where it is compressed to remove excess water.

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 – 6) and non-normal diagnostic sequences showing torque-out (Stages 7 – 10) for use in troubleshooting are shown.
Page 18
Normal operation – Stage 2 The water sensor verifi es water in the fl oat reservoir. The water OK LED (WTR) comes on. At the same time, the gearmotor, compressor and condenser fan motor come on, lighting the drive LED (DR) and compressor LED (C). The gearmotor is started through a current style relay that is pulled in by the initial high current draw of the run winding.
Page 19
Normal operation – Stage 4 Once the ice level control opens, the B-E LED goes out. After a 10 second delay the compressor LED (C), compressor and fan motor go off. (Should the ice level control not remain open for 10 seconds, the ice machine will continue to run.) The gearmotor continues to run and the DR LED remains on for 60 seconds.
Page 20
Normal operation – Stage 6 When the dwell time of 20 minutes has expired, the B-T LED goes off. The ice machine goes through the normal start-up sequence when the bin level control signals the control board for ice. The WTR LED will remain on as long as the water sensor in the fl oat reservoir senses water.
Page 21
Diagnostic sequence – Stage 8 If the restart is successful the 20M LED goes off, the 60 minute timer LED (60M) comes on. The 60M LED will remains on for 60 minutes from restart. A lighted 60M LED indicates the ice machine has experienced an over- torque condition.
Diagnostic sequence – Stage 10 If the water level in the fl oat reservoir drops to an unacceptable level, the WTR LED goes out, shutting the ice machine off. Also, the BT LED comes on, preventing the ice machine from restarting for twenty minutes. If water is restored, the WTR LED comes back on and fl ashes to alert the technician that water to ice machine has been lost.
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. Ice machine charge specifi cations Model Charge...
Ice capacity test Ice machine production capacity can only be determined by weighing ice produced in a specifi c time period. 1. Remove top panel and hopper lid of unit. 2. Weigh and record weight of container used to catch ice. 3.
Terminals: LI (incoming power, hot), L2 (neutral terminals), WTR (power terminal for water solenoid), WM (power terminal for wheelmotor), CLN (terminals for clean cycle switch). Note: SOL terminal not used in 12 series dispensers. Lens/sensor troubleshooting 1. Turn dispenser power switch off and remove slash panel.
Ice machine troubleshooting Flashing water LED at any time indicates that water signal to board had been lost for more than one second. Ten-second delay: There is a 10 second delay in reaction to loss of water (WTR) or bin (B-E) signals. If signals are not lost for more than 10 seconds, no reaction will occur.
