Page 8: Installing Wall Mount Dispensers
Installing wall mount dispensers WARNING • Wall mount dispensers are intended to be mounted above a sink, eliminating the need for a drain pan. • Before beginning installation verify that the sink size and location meet the requirements shown in Fig. 7. • If requirements are not met, a drain pan must be used to prevent ice and water from falling on counter or floor. • FAILURE TO TAKE THESE PRECAUTIONS COULD RESULT IN SLIPS AND FALLS ON WET FLOORS Fig. 7 Minimum Sink Requirements Minimum sink requirements (without drain pan) (shown without drain pan) Front View Front View Sink centered Sink centered below dispenser below chutes... - Page 9 Fig. 10 Dispenser bottom view 10.3 10.1 10.2 7.

Page 13: Service
The icemaking process The Follett icemaker uses a stainless steel jacketed evaporator and operates 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. -

Page 23: Icemaker Operational And Diagnostic Sequences
Icemaker operational and diagnostic sequences The wiring diagrams that follow illustrate the circuitry of Follett icemakers. Both normal operation (stages 1 - 6) and non-normal diagnostic sequences showing torque-out (stages 7 - 10) for use in troubleshooting are shown. Circuitry notes The icemaker receives power from two sources – the main power supply and the bin control signal power from the dispenser. -
Page 24: Normal Operation - Stage 1
Normal operation – Stage 1 Power is supplied to L1 of the control board. The ice level control in the dispenser is closed and calling for ice, supplying signal voltage to the control board. The control board will now go through the start-up sequence. Less than 30 seconds will elapse as the water sensor located in the float reservoir checks for water in the reservoir. -
Page 25: Normal Operation - Stage 3
Normal operation – Stage 3 After the initial high current draw drops off, the gearmotor start relay contacts open, dropping out the start winding. As the compressor comes up to normal running speed, the compressor start relay contacts also open, dropping out the start winding of the compressor. The icemaker is now in a normal icemaking mode. The icemaker will begin to produce ice and continue to produce ice until the bin level control in the ice dispenser is satisfied. -
Page 26: Normal Operation - Stage 5
Normal operation – Stage 5 The drive motor now shuts down and the DR LED is off. The B-T LED remains on for 20 minutes. The icemaker will not start while the B-T LED is on. To restart the icemaker for troubleshooting purposes, depress the reset button to clear the control board. -
Page 27: Diagnostic Sequence - Stage 7
Diagnostic sequence – Stage 7 The 20 minute error LED (20M) is on, indicating that the control board has sensed an over-torque condition (above 3 AMPS on the gearmotor). The 20M LED remains on for 20 minutes after an over-torque condition has occurred. The icemaker remains off as long as the 20M LED is on. When the 20M LED goes off, the control board will try to go through a normal start-up sequence. -
Page 28: Diagnostic Sequence - Stage 9
Diagnostic sequence – Stage 9 The second error (2ND) LED comes on if an over-torque condition occurs while the 60M LED is still lighted. The 2ND LED indicates that two consecutive over-torque situations have occurred. The icemaker will be shut down at this time and will not restart unless the manual reset button is depressed. -
