Operation Preventive maintenance Periodic cleaning of Follett’s icemaker 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. - Page 11 Fig. 10 12. Fill reservoir (Fig. 7.2) with Solution A. 13. Turn bin signal switch (Fig. 8.1) on electrical box of icemaker ON (to allow gearmotor to run). 14. Wait 10 minutes. Turn compressor switch ON (Fig. 8.3). 15. Keep reservoir (Fig. 7.2) full of Solution A while making ice for 20 minutes.

Page 12: 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. This valve also shuts off the water supply when the icemaker is not running. -

Consult factory Refrigeration replacement requirements 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 17: Evaporator Unit Electrical Control System Operation
The Bin Empty LED (B-E) will be on. *The high voltage bin signal connection is used on all Follett ice dispenser applications. The high voltage terminals respond to applied voltage of 24 to 240 volts from the dispenser. - Page 18 Normal operation – Stage 2 – Gearmotor start The water sensor verifies water in the float. The Water OK LEDs (WTR) comes on. At the same time, the gearmotors come on, lighting the Drive LEDs (DR). The gearmotor start windings are energized through a current relay.
- Page 19 Normal operation – Stage 3 – Refrigeration start Seconds later the C LEDs come on and the coils of both of the relays are energized, closing their normally open contacts. This completes the circuit to the coil of the liquid line solenoid valve. The valve opens increasing the pressure in the suction line.
- Page 20 Normal operation – Stage 4 – Ice bin full The ice level control opens, the B-E LED goes out. After a 10 second delay the LEDs (C), go off de-energizing the relays which closes the liquid line solenoid valve. The refrigeration system will pump down and turn off by the low pressure control.
- Page 21 Normal operation – Stage 5 – Off cycle time delay The B-T LEDs will remain on for 20 minutes. The icemaker will not start while the B-T LEDs are on. To restart the icemaker for troubleshooting purposes, depress both reset buttons to clear the control boards. 115 VAC 60 HZ ELECTRICAL BOX...
- Page 22 Normal operation – Stage 6 – Off cycle When the dwell time of 20 minutes has expired, the B-T LEDs go off. The icemaker will go through the normal start-up sequence when the bin level control signals for ice. The WTR LED will remain on as long as the water sensor in the float reservoir senses water.
- Page 23 Diagnostic sequence – motor over-current condition If either of the circuit boards senses a current over 3 amps, five things happen: 1. The DR LED goes out, the DRV terminal is de-energized and the gearmotor shuts down. 2. The C LED goes out, the FAN terminal is de-energized, cutting power to the coil of the relay. 3.
