Satellite-fill icemaker installation procedure Install 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.
Field wiring diagrams 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.
Install 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.
Step 2 – Installing icemaker on slide-out track A. When icemaker is shipped with slide-out track accessory (follow either A or B) 1. Connect inlet water, drain, and power supply to back of vertical utility panel. 2. Place icemaker on slide-out track assembly. 3. Connect drain and water lines. 4. Connect electrical cords from icemaker to appropriate plug and connect to power supply. B. When icemaker is installed in and shipped with counter 1.

Block off any open area outside of the air duct. Intake air requirements — air-cooled icemakers (MCC400A & C/ER400A only) 1. Check that 51mm (2") duct is installed on condenser front. 2. Cut a 305mm x 305mm (12" x 12") opening in counter face to align with duct. 3.
Satellite-fill icemaker ice transport tube installation Incorrect ice transport tube installation can result in wet ice and dispensing problems. Follow guidelines below to ensure correct installation. Call factory for assistance if you are unable to meet these requirements. General requirements Maximum length of tube run – 6m (20 ft). Factory approval required for longer runs. Run tube without dips. One continuous length of tube; no splices. Minimum radius of bends in tube – 153mm (6") inside radius.
Additional ice transport tube connection specifications for Vision series ice and beverage dispensers 1. Push one end of ice transport tube(s) through hole(s) provided in side of dispenser. 2. Route tube into ice tube bracket inside dispenser and engage bracket tabs in holes located in end of ice transport tube(s). (see drawings below) 3. Verify bin thermostat capillary tube is mounted correctly.

Check each item listed and call factory immediately for assistance if you experience problems with unit. Before turning on power 1. Turn on water to icemaker. 2.
Monthly condenser cleaning (air-cooled icemaker only) 1. Use a vacuum cleaner or stiff brush to carefully clean condenser coils of air-cooled icemakers to ensure optimal performance. 2. When reinstalling counter panels in front of remote icemakers, be sure that ventilation louvers line up with condenser air duct.

Service Icemaker Operation Follett’s icemaker consists of four distinct functional systems: • Refrigeration system • Water system • Harvesting system • Electrical control system These four systems work together to accomplish the production and harvesting of ice. A problem in any one of these systems will result in improper operation of the entire ice production cycle.
Technical specifications (all models) Refrigeration system diagram high side service port high pressure switch condenser filter dryer low side service port evaporator compressor high pressure vapor thermostatic expansion valve high pressure liquid low pressure liquid low pressure vapor C/ET400A/W wiring diagram Follett icemakers used on top of an ice storage bin (C/ET400A/W) have a slightly different circuitry. A diagram for these icemakers is shown below.
Table 1 – Refrigeration pressure data Notes: 1) 2) Water regulating valve is factory set at 225 PSIG head pressure. Readings within 10% of above table values should be considered normal. Air-cooled Icemaker Refrigeration Pressure Discharge Pressure/Suction Pressure Ambient air temperature °F °C 16 10 12/1.6 16.9/2.1 16.3/2.5 bar 21 12/1.6 16.8/2.1 22.5/2.6 bar 13.1/1.7 18.3/2.2 23.9/2.
Electrical control system operation The wiring diagrams which follow illustrate the circuitry of Follett icemakers used with ice dispensers. Both normal operation of the icemaker (Stages 1 - 6) and non-normal diagnostic sequences showing torque-out (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.
Normal operation – Stage 2 The water sensor verifies water in the float 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.
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 icemaker will continue to run.) The gearmotor continues to run and the DR LED remains on for 60 seconds. The purpose of this function is to drive the remaining ice out of the evaporator and to boil off any refrigerant remaining in the evaporator.
Normal operation – Stage 6 When the dwell time of 20 minutes has expired, the B-T LED goes off. The icemaker 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 float reservoir senses water.
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 icemaker has experienced an over-torque condition. If the icemaker runs without problems for 60 minutes and no additional torque errors occur, the 60M LED goes off and the icemaker continues normal operation.
Diagnostic sequence – Stage 10 If the water level in the float reservoir drops to an unacceptable level, the WTR LED goes out, shutting the icemaker off. Also, the BT LED comes on, preventing the icemaker from restarting for twenty minutes. If water is restored, the WTR LED comes back on and flashes to alert the technician that water to icemaker has been lost. The icemaker restarts at the end of the 20 minute time delay. The flashing WTR LED can be cleared by pressing the reset button.
Refrigeration system (all models) All service on refrigeration systems must be performed in accordance with all federal, state and local laws. It is the responsibility of the technician to ensure that these requirements are met. Recharging icemaker to other than factory specifications will void the warranty.
Fig. 7 Service procedures Evaporator disassembly (Fig. 7) 1. Disconnect power to icemaker. 2. Shut off water to icemaker. 3. Drain evaporator and float tank. 4. Disconnect plastic tubing from evaporator water inlet, drain pan stub, compression nozzle tubing and reservoir overflow tubing from secured clip. 5. Disconnect ice transport tube from compression nozzle. 6. Remove nut and upper vee band coupling from top of evaporator. 7.
Troubleshooting chart Flashing water LED at any time indicates that water signal to board had been lost for more than one second. Ten-second delay: There is a 10 second delay in reaction to loss of water (WTR) or bin (B-E) signals. If signals are not lost for more than 10 seconds, no reaction will occur. Problem 1. Icemaker will not run. System status: compressor, gearmotor, and fan motor inoperative. 2. Compressor will not run. System status: gearmotor and fan motor run. 3. Unit cycles intermittently.
Troubleshooting Problem 6. Icemaker runs for short period of time and shuts down on torque error. System status: 20M or 2nd LED are lit. 7. Evaporator is iced up on the outside. No ice production. Indicators/possible cause 1. Kink in ice transport tube. 2. Bin level control remains in closed position. 3. Ice transport tube ruptured internally. 4. Worn evaporator bearings. 5. Faulty gearmotor start relay. Icemaker torques out within 5 seconds of start-up. 6.
