These procedures ensure that the ice machine can be easily removed as one unit for cleaning and maintenance. For installation with the slide-out accessory, refer to instructions to install ice machine and rough-in utilities with optional slide-out accessory.

    The icemaking process The Follett ice machine 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 fl oat valve. This valve also shuts off the water supply when the ice machine is not running.

  • Page 25 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 normally open current style relay that is pulled in by the initial high current draw of the run winding.
  • Page 26 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 27 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 28 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.
  • Page 29 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.
