Operation
Cleaning/descaling 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/descaling and sanitizing 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.
Cleaning of the condenser can usually be performed by facility personnel. Cleaning/descaling and sanitizing 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
§ Refrigeration system
§ Water 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. 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 a oat valve.
This valve also shuts off the water supply when the ice machine is not running.
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 (10RPM) 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 1) and level detecting sensors. Water sensing
rods (Fig. 2) 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.

ATTENTION!
To prevent circuit breaker overload, wait 15 minutes before restarting this unit. This allows the compressor
to equalize and the evaporator to thaw.
Normal control board operation
The PC board indicator lights provide all the information necessary to determine the machine's status. Green
indicator lights generally represent “go” or normal operation; Yellow indicators represent normal off conditions; Red
indicators generally represent alarm conditions, some of which will lock the machine off.
A ashing green light labeled POWER indicates power to the machine. All other normal operation status indicators
are covered as follows:

Relay/triac output indication
Each relay on the board has an indicator light associated with its output. For example, when the relay for the water
feed solenoid is energized, the adjacent indicator light glows green.
Flushing logic
Off cycle: At the completion of off-cycle time delay, the machine checks for a cumulative one (1) hour of ice making
time since the last off-cycle ush. If the cumulative ice making time exceeds one (1) hour, the machine will open
the drain valve for 60 seconds to drain the evaporator in its entirety. It will then rell with water, ush again and rell,
and begin making ice. If the ice making time is less than 1 hour, the machine will start and begin making ice without
draining the evaporator.
Error faults
The Maestro Plus PC board monitors various operating parameters including high pressure, auger gearmotor
amperage limits, clogged drain, and low water alarm conditions. There are two types of errors namely “hard” or “soft”.
A hard error is one that shuts the machine off and will not allow restart until the reset button is pressed. Even cycling
power will not reset a hard error. A soft error can either be automatically reset should the condition rectify, or if power
is cycled. Should an error occur, consult the troubleshooting guide in this manual or a Follett service technician.
Soft errors:
Note: For all soft errors, the ice machine will remain off for 1 hour.
LO WATER: During operation, the water level cycles between the normal low and normal high sensors. Should the
water be shut off to a running machine, a soft error will occur. The error sequence is as follows: During operation,
the water level falls to the normal low sensor, and when it does the water feed solenoid is energized. If water is not
detected at the normal low sensor within 10 seconds, a soft error will occur. The machine will shut down and TIME
DELAY and LOW WATER LEDs will be lit. After time delay, the solenoid will energize and remain energized until the
water level is sufficient for restart.
HI PRESSURE: Should the refrigeration pressure rise above 425 psi, the machine will shut down and the TIME
DELAY and HIGH PRESSURE will be illuminated. After the time delay, and if the pressure has fallen back below the
reset point of 295 psi, the machine will restart and the TIME DELAY and HIGH PRESSURE will clear.
HI AMPS: The PC board monitors the amperage of the auger motor. Should the gear motor experience current draw
above the allowable 1.8A limit or no current draw (0A), the machine will shut down and the TIME DELAY and HI AMP
will be illuminated. After the time delay the machine will restart and the TIME DELAY and HI AMP will clear.
Hard error:
HI AMPS: If a second hi-amp error occurs within 1 hour of the initial hi-amp error, the ice machine will shut off and
the reset on the board must be pressed to clear the error. If a second hi-amp has occurred, the HI AMP LED only will
be illuminated.
DRAIN CLOG: The drain clog sensor, located in the evaporator drain pan will detect the presence of water just below
the top edge of the pan. If water does not properly ow out of the internal or external drain lines it will backup into the
drain pan (especially during a self-ushing purge cycle). Pressing the reset button will restart the ice machine.

Electrical control system operation
The wiring diagrams that follow illustrate the circuitry of these Follett ice machines used with ice dispensers. Both
normal operation of the ice machine (Stages 1–6) and non-normal diagnostic sequences showing torque-out
(Stages 7–10) for use in troubleshooting ice machine problems are shown.
Circuitry notes
When the ice machine is used with a dispenser it receives power from the main power supply. Disconnect the
power source before performing service. When performing electrical service, always use a meter to determine
whether or not the components being serviced are energized.
§ High pressure cutout opens at 425 PSI (2930.3 kPA) and closes at 287 PSI (1978.8 kPA)(auto reset).
§ The bin signal input to the control board in the 425A/W ice machine must only be initiated by contact closure. Do
not supply power. To run the ice machine in the workshop, use the bin signal jumper (P/N 01069095).

Normal operation – Stage 1 - 230V 50 Hz
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.

Normal operation – Stage 5
As the compressor comes up to normal running speed, its start winding generates a voltage potential across the
relay’s coil. This energizes the coil to open the contact and drop out the start capacitor.
The ice machine is now in a normal ice making mode. The ice machine will produce ice until the bin level control
in the ice dispenser is satised.

Quiet Night/Sleep cycle
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
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.

down (strike one). The HI AMPS and TIME DELAY LEDs will remain on for 60 minutes after an over-torque
condition has occurred. The ice machine will remain off as long as these two LEDs are on. After the 60 minute time
delay, these LED lights turn off, and the control board will try to go through a normal start-up sequence.

High gearmotor amps – Stage 2
If the restart is successful the board will continue to monitor the current draw on P4 for 60 minutes looking for a
second high amps (above 1.8A) or no current draw (0A) occurrence. If the ice machine runs without problems for
60 minutes and no additional torque errors occur, the ice machine will continue normal operation.

Loss of water
Water Sensors
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 (2930.3 kPA), 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 (2034.0 kPA) 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.

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 ice machine to other than
factory specications will void the warranty.
R404A ice machine charge specications
Model Charge Refrigerant type
Air-cooled) 15 oz. (425 g) R404A
Water-cooled) 9 oz. (255 g) R404A
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 LLC 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.
Ice capacity test
Ice machine production capacity can only be determined by weighing ice produced in a specic time period.
Replace all panels on ice machine.
1. Run ice machine for at least 15 minutes.
2. Weigh and record weight of container used to catch ice.
3. Catch ice for 15 or 20 minutes.
4. Weigh harvested ice and record total weight.
5. Subtract weight of container from total weight.
6. Convert fractions of pounds to decimal equivalents (ex. 6 lb 8 oz. = 6.5 lb).
7. Calculate production using following formula:
1440 min. x wt. of ice produced
= Production capacity/24 hr. period
Total test time in minutes
8. Calculated amount per 24 hours should be checked against rated capacity for same ambient and water
temperatures in Ice Production Tables.
