Install refrigeration line
Note: The installer of the refrigeration line set must be USA Government-Environmental Protection Agency
(EPA) certified in proper refrigerant handling and servicing procedures.
A qualified person must perform all roof or wall penetration.
Do not form unwanted traps in refrigeration lines. A service loop is not considered an oil trap.
Never coil excess refrigeration tubing.
The compressor oil rapidly absorbs moisture. Minimize the exposure of the refrigeration system by
not releasing the condenser unit or evaporator unit holding charge until all line connections are
finished and the system is ready for evacuation.
To prevent oxidation of the copper, purge line set and condenser unit with dry nitrogen while brazing.
For lines longer than fifty feet, add one additional pound of R404A refrigerant for every 25 feet of line run
up to 100 feet (see refrigeration charge table). Consult factory for line runs beyond 100 feet.
It is recommended that both liquid and suction lines are run and insulated together for the first 15
feet from the condensing unit. This protects the system from sub-cooling loss and/or liquid slugging
the compressor.

Service
Condenser unit operation
The condensing unit is weatherproof and equipped to operate in ambient temperatures from – 20°F – 130°F
(– 29°C – 54.4°C). A dual pressure control provides compressor protection from excessive head pressures,
pumps the refrigeration system down and shuts the condensing unit off when the solenoid valve on the
evaporator unit is closed.
Low ambient operation: Reliable operation at low ambient temperature is achieved with a pumpdown cycle, a
crankcase heater and a head pressure control valve. As the ambient temperature falls and the head pressure
decreases the valve maintains a minimum head pressure of 215 psi by bypassing discharge gas around the
condenser to the receiver to increase the pressure at the condenser outlet. This backs liquid refrigerant up in the
condenser to reduce the area available for condensing which increases the head pressure to maintain the 215
psi set point. A check valve is installed in the liquid line between the receiver and the condenser to prevent liquid
migration from the receiver to the condenser during the off cycle. The crankcase heater works in conjunction with
a continuous pumpdown cycle to prevent accumulation of liquid refrigerant in the compressor oil during the off
c This prevents compressor damage due to a flooded compressor start. The low pressure control will start the
condensing unit anytime the low side pressure rises above the 30 psi set point and pump the refrigerant out until
the pressure falls to 10 psi. The crankcase heater, which is energized whenever the condensing unit has power,
keeps the compressor oil warmer than the coldest location in the system. This minimizes off cycle refrigerant
migration. If power to the condensing unit is interrupted after the system is charged the compressor should not be
started unless the crankcase heater has been energized for at least four hours immediately prior to compressor
startup. However the compressor can safely be started during the refrigeration system charging process (without
the warm-up period) once sufficient refrigerant is in the system to maintain a positive pressure on the suction side
of the compressor.
Evaporator unit operation
Follett’s icemaker consists of four distinct functional systems:
1. Refrigeration system
2. Electrical control system
3. Water system
4. Harvesting 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. When troubleshooting the
icemaker, it is important to analyze the entire system operation to determine which system is not functioning
properly, then pinpoint the component within that system that is malfunctioning. Determine what corrective action
must be taken before making any adjustments or replacing any components.
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.
When the icemaker is running, a layer of ice forms on the interior surface of the evaporator. This ice is continuously
removed by a slowly rotating (12 RPM) auger. The auger carries the ice upward into the cavity formed by the top
bearing housing and the compression loop, where it is compressed to remove excess water. When the ice reaches
the desired hardness it rotates within the cavity and is forced through a discharge port and compression nozzle and
into the ice transport tube. The discharge tube and compression nozzle are slightly restricted to further compress the
ice and produce the desired hardness. As the formation of ice continues, ice in the transport tube is pushed through
the tube to the storage compartment in the ice dispenser or ice storage bin.
A solid state control board located in the electrical box of the icemaker controls the normal operation of the icemaker
and monitors gearmotor torque. This control board will shut down the icemaker should an over-torque condition
occur. It is very important that you familiarize yourself with the operational sequences detailed in this manual before
attempting to service the icemaker.

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.
In the event of system contamination (for example, a compressor burn out, refrigerant leak, presence of noncondensibles or moisture), the system must be repaired, evacuated and recharged using virgin or reclaimed
refrigerant that meets ARI standard 700-88.
Follett Corporation does not approve of recovered refrigerants. Improper refrigeration servicing procedures will
void the factory warranty.

Power is supplied to L1 on the control boards. The ice level control in the storage bin is closed completing the
circuit between the terminals of the low voltage bin signal connection*. The control boards will now go through the
start-up sequence. Less than 30 seconds will elapse as the water sensor located in the float reservoir checks for
water in the reservoir. 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.

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. The low-pressure control then starts the condensing unit. As the gearmotors
reach normal speed the current relays re-open, dropping out their start windings. The icemaker is now in normal
icemaking mode.

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. (Should the ice level control not remain open for 10 seconds, the icemaker will continue to run.)
The BT LEDs come on. The gearmotors continue to run 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.

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. The relay contacts open, cutting power to the coil of the solenoid valve and the condensing unit
pumps down.
4. The condensing unit shuts off on the low pressure control.
5. The 20M LED is turned on.
After 20 minutes the 20M light is turned OFF and the machine goes through the normal start-up described above.
If the restart is successful, the 60M light is turned ON and remains ON for 60 minutes. This alerts the user to a
problem in the drive system. If the icemaker runs without an overcurrent condition during the 60 minute period the
60M LED will go out and the icemaker will continue normal operation. If the restart is unsuccessful, or if the board
detects another 3 amp current during the 60 minute period, the 2ND light is turned ON and the machine shuts
down and can only be started by pressing the reset button.
Diagnostic sequence – no water
If the water level in the float reservoir drops too low, three things happen:
1. The WTR light is turned OFF.
2. The ice machine shuts down.
3. The BT light turns ON.
If water is restored, the WTR light will flash, the BT light will turn OFF after 20 minutes, and the machine goes
through the normal start-up described above. The flashing light can be cleared by pressing the reset button.
