Page 4: Before You Begin
Before you begin • After uncrating and removing all packing material, inspect the equipment for concealed shipping damage. If damage is found, notify your shipper immediately and contact Follett Corporation for help in filing a claim, if necessary. • Check your paperwork to determine which model dispenser you have. Follett model numbers are designed to provide information about the type and capacity of Follett ice dispensing equipment. -

Page 6: Installation Procedures
Installation procedures Before you begin • All dispensers must be installed level in both directions to ensure proper operation. • Required service and ventilation clearances: 6" (153mm) on right side of dispenser, 12" (305mm) at top. • 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 out back). -

Page 10: User Information
User information How the dispenser works Follett’s 12 series automatic load ice and water dispensers are equipped with Follett’s 400 lb (181kg)/day icemaker. In Follett’s continuous icemaking process, water freezes to the inside walls 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 11: Icemaker Cleaning And Sanitizing
Cleaning of the condenser can usually be performed by facility personnel. Cleaning of the icemaker system in most cases should be performed by your facility’s 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: Start-Up Following Cleaning
Most ice machine cleaners contain citric or phosphoric acid which can cause skin irritation. Read caution label on product and follow instructions carefully. 7. Plug evaporator drain hose and pour part of cleaning solution into reservoir, filling almost to overflowing. 8. -
Page 13: Service Information
The icemaking process Follett icemakers use a wrapped tube evaporator and operate on a continuous freezing cycle. Water is supplied to the evaporator from the water reservoir where the water level is controlled by a float valve. This valve also shuts off the water supply when the icemaker is not running. -

Page 16: Icemaker Operational And Diagnostic Sequences
Icemaker operational and diagnostic sequences The wiring diagrams that follow illustrate the circuitry of Follett icemakers 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 17 Normal operation – Stage 2 The water sensor verifies water in the float. 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 compressor is started through a current style relay that is pulled in by the initial high current draw of the compressor.
- Page 18 Normal operation – Stage 4 Once the ice level control opens, the B-E LED goes out. After a 10 second delay the LED (C), compressor and fan motor go off. (Should the ice level control not remain open for 10 seconds, the icemaker will continue to run.) The gearmotor continues to run for 60 seconds.
- Page 19 Normal operation – Stage 6 When the dwell time of 20 minutes has expired, the B-T LED goes off. The icemaker will go 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 float reservoir senses water.
- Page 20 Diagnostic sequence – Stage 8 When the 20M LED goes off, the 60 Minute Timer LED (60M) comes on. The 60M LED will remain on for 60 minutes from restart. A lighted 60M LED tells the technician that the icemaker has experienced an over-torque condition.
-
Page 21: Refrigeration Cycle Diagram
Diagnostic sequence - Stage 10 If the water level in the float reservoir drops to an unacceptable level, the WTR LED will go out, shutting the icemaker off. Also, the BT LED will come on, preventing the icemaker from restarting for twenty minutes. If water is restored, the WTR LED will come back on and flash to alert the technician that water to icemaker has been lost. -

Page 23: Refrigeration System Data And Requirements
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. If additional refrigerant is required, virgin or reclaimed refrigerant that meets ARI standard 700-88 must be used. -
Page 24: Dispenser Troubleshooting - Lever/Sensorsafe Models
Ice capacity test Icemaker production capacity can only be determined by weighing ice produced in a specific time period. 1. Remove top panel and hopper lid of unit. 2. Run icemaker for at least 15 minutes. 3. Weigh and record weight of container used to catch ice. 4. -
