Installing Satellite-fill icemaker and rough-in utilities without optional slide-out accessory The requirements below are for icemaker installation without the Follett slide-out accessory. These procedures ensure that the icemaker can be easily removed as one unit for cleaning and maintenance. For installation with the slide-out accessory, refer to instructions to install icemaker and rough-in utilities with optional slide-out accessory. - Page 9 Field wiring diagrams for Satellite-fill icemaker installations All field wiring must be installed in accordance with NEC and local electrical codes. Field wiring diagram is intended only to aid electrician or technician in understanding how equipment works. Should local codes require a hard-wired connection and/or shielded wiring, eliminate the cord and plug(s) and follow the appropriate field wiring diagram.
- Page 10 Installing Satellite-fill icemaker and rough-in utilities with optional slide-out accessory The slide-out accessory allows the icemaker to be pulled out on a track from below a counter without disconnecting utilities. A leg supports the icemaker in the full-out position. If your order did not include a slide-out accessory proceed to icemaker ventilation and exhaust.

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. -

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. -

MCD400A/WBT, MCD400A/WHT and MFD400A/WBT wiring diagram Follett icemakers used on top of an ice storage bin have a slightly different circuitry. A diagram for these icemakers is shown below. The operational and diagnostic stages for these icemakers will be otherwise the same as the following stages 1 - 10. -
Page 21: Electrical Control System Operation
(Stages 7 - 10) for use in troubleshooting icemaker problems are shown. Follett icemakers used on top of an ice storage bin have a slightly different circuitry. The operational and diagnostic stages for these icemakers will be otherwise the same as Stages 1 - 10 that follow. - Page 22 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).
- Page 23 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 icemaker will continue to run.) The gearmotor continues to run for 60 seconds.
- Page 24 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 25 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 icemaker has experienced an over-torque condition.
- Page 26 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.
