    The requirements below are for ice machine installation without the Follett slide-out accessory. 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.

    Cleaning and preventive maintenance (all models) Preventive maintenance Periodic cleaning of Follett’s 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.

  • Page 19: Service

    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.

    MCD400A/WBT, MCD400A/WHT and MFD400A/WBT wiring diagram Follett ice machines used on top of an ice storage bin have a slightly different circuitry. A diagram for these ice machines is shown below. The operational and diagnostic stages for these ice machines will be otherwise the same as the following stages 1 - 10.

  • Page 22: Electrical Control System Operation

    (Stages 7 - 10) for use in troubleshooting ice machine problems are shown. Follett ice machines used on top of an ice storage bin have a slightly different circuitry. The operational and diagnostic stages for these ice machines will be otherwise the same as Stages 1 - 10 that follow.
  • Page 23 Normal operation – Stage 2 The water sensor verifi es water in the fl oat. 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).
  • Page 24 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 and the B-T LED comes on. (Should the ice level control not remain open for 10 seconds, the ice machine will continue to run.) The gearmotor continues to run for 60 seconds.
  • Page 25 Normal operation – Stage 6 When the dwell time of 20 minutes has expired, the B-T LED goes off. The ice machine 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 fl oat reservoir senses water.
  • Page 26 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 remain on for 60 minutes from restart. A lighted 60M LED tells the technician that the ice machine has experienced an over-torque condition.
  • Page 27 Diagnostic sequence – Stage 10 If the water level in the fl oat reservoir drops to an unacceptable level, the WTR LED will go out, shutting the ice machine off. Also, the BT LED will come on, preventing the ice machine from restarting for twenty minutes. If water is restored, the WTR LED will come back on and fl ash to alert the technician that water to ice machine has been lost.
