User information
How the dispenser works
Follett’s 25/50CI series automatic-load ice and water dispensers are equipped with Follett’s 425 lb (181kg)/day
ice machine. In the continuous icemaking process, water freezes to the inside wall of the evaporator. A rotating
stainless steel auger carries the ice to the top of the evaporator where it is compressed and extruded through an
outlet port. The ice is then pushed through a tube to the storage hopper. When the hopper is full, a bin thermostat
opens and shuts the ice machine off. When the dispense mechanism is activated, a dispense motor is turned on,
causing the wheel to turn. This moves ice to the dispense chute where it drops by gravity into the container held
below the chute.
How SensorSAFE infrared dispensing works
Follett’s SensorSAFE infrared dispensing maximizes sanitation and minimizes the possibility of cross-contamination
by eliminating physical contact between the cup or container and dispenser. Sensors in the panel use reected
infrared light to detect the presence of the container and send a signal to a control board which then activates the
appropriate components for ice or water dispensing.
The SensorSAFE infrared dispensing package includes a cleaning switch under the left side of the front cover
which temporarily shuts off dispensing to allow cleaning of the panel and lenses. If the switch is not turned back on
after cleaning, the dispenser automatically resets after two minutes for normal operation.
SensorSAFE infrared dispensing also includes a time limit safety feature which automatically stops ice dispensing
after one minute of continuous dispensing. Dispensing can be resumed by moving the container away from the
dispenser and returning it to the activation zone.
Cleaning and sanitizing
Follett ice machines and dispensers, and their associated cleaning and sanitizing procedures, are designed for
use with potable water sources. The presence, or suspected presence, of infectious agents may call for additional
measures, including the replacement of components and more comprehensive disinfection measures. Follett
recommends that these cleaning and sanitizing procedures be reviewed with the appropriate infectious agent
subject matter experts to assure complete remediation.
Periodic cleaning of Follett’s ice and water dispenser and 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.
Follett recommends sanitizing the pressurized water lines prior to cleaning the ice machine/dispenser. Follett
offers two kits: order P/N 01089572 when a Follett lter system with a pre-lter bowl is present, or P/N 01089580
when a Follett lter system is not present. Follow the instructions provided with the respective kits to sanitize the
pressurized water lines immediately before cleaning the ice machine/dispenser.
Cleaning of the condenser can usually be performed by facility personnel. Cleaning of the ice machine system
should be performed by your facility’s trained 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. Service problems resulting from lack of preventive maintenance will not be covered under the
Follett warranty.

Service
Ice machine Operation (all models)
Follett’s ice machine consists of four distinct functional systems:
§ Harvesting system
§ Water system
§ Electrical control system
§ Refrigeration 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 ice
machine, 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 Maestro Plus 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 conductivity
probes.
When the ice machine is running, a layer of ice forms on the interior surface of the evaporator. This ice is
continuously removed by a slowly rotating (12RPM) 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.
A solid state control board located in the electrical box of the ice machine controls the normal operation of the ice
machine and monitors gearmotor torque. This control board will shut down the ice machine 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 ice machine.

Water system
The water level in the evaporator is controlled by a ll solenoid (Fig 13) and level detecting sensors. Water sensing
rods (Fig. 14) extend down into the reservoir at the end of the evaporator assembly. The system works via electrical
conductivity as follows:
One of the longest probes is a common. When water is between any of the other probes and the common, the
PC board will sense the activation. During normal operation, the water level rises and falls between the Normal
High and Normal Low sensors. As water is consumed to make ice, the level will fall until the Normal Low sensor is
exposed, triggering the water feed solenoid on. Water will ll until the Normal High sensor is activated.
Note: The potable water dissolved solids content must be greater than 10 ppm for the water control system to
function properly. If using reverse osmosis water ltration system, ensure T.D.S level is greater than 10 ppm.

Ice machine operational and diagnostic sequences
The wiring diagrams that follow illustrate the circuitry of Follett ice machines used with 25/50 series ice dispensers.
Both normal operation (stages 1—8) and non-normal diagnostic sequences showing torque-out for use in
troubleshooting are shown.
Circuitry notes
§ Bin signal is contact closure only — DO NOT SUPPLY POWER.
Note: The operation stage descriptions that follow are based on the unit containing the split-phase gear
motor.
Normal operation – Stage 1
Power is supplied to L1 of the control board, the POWER LED light begins ashing. The ice level bin thermostat in
the dispenser is closed and calling for ice, supplying contact closure to the control board. The LOW BIN LED will be
on. The control board will now go through the start-up sequence. The board checks the water sensors (located in
the reservoir) for continuity between the common probe (B) and the high probe (C). If continuity is not sensed, the
water ll valve (P21) is energized.

Quiet Night/Sleep cycle (Symphony Plus only)
The board monitors ice dispensing through a line voltage input to P15. If the ice dispense has not be initiated for
more than 5 seconds during the 20 minute time delay, the SLEEP CYCLE LED comes on. The machine will stay off
for 12 hours unless 5 seconds of dispensing is seen. After 12 hours, the SLEEP CYCLE LED goes out and the ice
making will resume if the bin thermostat is closed. The sleep cycle dispense duration is adjustable using the DIP
switches on the control board.

Self-ushing (when enabled)
At the completion of the 20 minute time delay, the machine checks for a cumulative one hour of ice making time
since the last off-cycle ush. If the cumulative ice making time exceeds one hour, the machine will energize the
drain valve P19 for 60 seconds to drain the evaporator. It will then rell with water, ush again, rell and begin
making ice if the LOW BIN LED is on. If the ice making time is less than 1 hour, the machine will start and begin
making ice without draining the evaporator.

High gearmotor amps – Stage 3
If a second occurrence happens during the 60 minute monitoring period, the HI AMPS LED will come on again
and shut the machine down (strike two). The HI AMPS LED (wihout the TIME DELAY LED) will indicate to the
technician that two consecutive over-torque situations have occurred. The ice machine is shut down at this time and
locked out. It will not restart unless the manual reset button is depressed while power is on.

Loss of water
During operation, the water level cycles between the normal low (D) and normal high (C) water probes - the ll
valve (P21) cycling on and off. If continuity is not detected between the common probe (B) and normal low (D)
within 10 seconds, the LOW WATER and TIME DELAY LEDs will come on and the machine will shut down for
the one hour time delay period. After the time delay, the ll valve will re-energize and wait for continuity between
the common probe and normal high before restarting. LOW WATER LED will remain ON until the water level is
satised.

High refrigerant pressure
Should the refrigeration pressure rise above 425 psi, the high pressure switch contacts will open. The board sees
the open circuit and the HIGH PRESSURE and TIME DELAY LEDs will come on, the machine shuts down. After
the one hour time delay, the machine will attempt to restart. If the pressure has fallen below the reset point of 295
psi and the board see the contacts closed, the machine will resume normal operation. If the contacts are still open
after the restart, the board will again go into HIGH PRESSURE and TIME DELAY, cycling until contact closure is
seen.

Ice capacity test
Ice machine production capacity can only be determined by weighing ice produced in a specic time period.
1. Remove top panel and hopper lid of unit.
2. Weigh and record weight of container used to catch ice.
3. Run ice machine for at least 15 minutes.
4. Catch ice for 15 or 20 minutes.
5. Weigh harvested ice and record total weight.
6. Subtract weight of container from total weight.
7. Convert fractions of pounds to decimal equivalents (Ex. 6 lbs 8 oz = 6.5 lbs).
8. Calculate production using following formula:
1440 min. x wt. of ice produced
= Production capacity/24 hr. period
Total test time in minutes
9. Calculated amount per 24 hours should be checked against rated capacity for same ambient and
water temperatures in Ice Production Table (see page 23).

Refrigeration system
Important: All service on refrigeration system must be performed in accordance with all federal, state and local
laws that pertain to the use of refrigerants. It is the responsibility of the technician to ensure that these requirements
are met.
Model Charge Refrigerant type
25/50CI425A, 25/50HI425A (air-cooled) 15 oz R404A
25/50CI425W (water-cooled) 9 oz R404A
CAUTION!
§ Recharging of unit at other than factory specications will void ice machine warranty.
Refrigerant replacement requirements
1. 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.
2. In the event of system contamination (for example, a compressor burn out, refrigerant leak, presence of
non-condensibles or moisture), the system must be repaired, evacuated and recharged using virgin or
reclaimed refrigerant that meets ARI standard 700-88.
3. Follett Corporation does not approve of recovered refrigerants. Improper refrigeration servicing
procedures will void the factory warranty.
Evacuation
Evacuate the system to a level of 500 microns. When the 500 micron level is reached, close valves and both
manifold and shut down the vacuum pump. Allow the system to sit for approximately 20 minutes. During this period
the system pressure should not rise. If the system pressure rises and stabilizes there is moisture in the system and
further evacuation is needed. If the pressure continues to rise check the system for leaks.
