Periodic Cleaning and Sanitizing
Periodic cleaning/descaling and sanitizing of Follett’s ice and water dispenser and icemaker 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 icemaker 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.
Condenser

Service
CAUTION!
§§ No service or maintenance should be performed until the technician has thoroughly read this service manual.
Except for routine cleaning and sanitizing, only qualified technicians should attempt to service or maintain this
equipment.
Overview
How the Machine Works
Follett’s automatic-load icemaker is equipped with Follett’s 425 lb (193kg)/day ice technology. 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 integrated ice storage bin. When the bin is full, a bin thermostat opens and turn
OFF the icemaker.
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 overtorque
condition occur. It is very important that you familiarize yourself with the operational sequences detailed in this
manual before attempting to service the icemaker.
Ice enters the integrated ice bin. Using the scoop supplied with the unit, you can easily take the ice out of the bin.
There is a scoop holder located on the internal wall. When ice is emptied from the ice bin, the thermostat capillary
tube gets warm and signals the machine to produce ice. There is no need turn off the machine during its normal
operation.

Water System
The water level in the evaporator is controlled by a feed solenoid and level detecting sensors. Referencing the
diagram below, water sensing rods extend down into the reservoir. 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 water level will fall until the Normal Low
sensor is exposed, triggering the water feed solenoid to turn on. Water will fill 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 a reverse osmosis water filtration system, ensure TDS (total
dissolved solids) 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 flashing green light labeled POWER indicates power to the machine. All other normal operation status indicators
are covered as follows:

FLASHING
1. Icemaker is making ice.
1. Normal running.
2. Icemaker is not making ice.
2. Normal time delay. When the bin fills with ice, the LOW BIN
light goes out momentarily and the refrigeration and auger
drive systems immediately shut down. (Note: The fan motor will
continue to run for 10 minutes to cool condenser). The TIME
DELAY LED lights, initiating the time delay period. When the
time delay expires, the machine will restart as long as the LOW
BIN light is on.

Integrated Icemaker
Error Faults:
The PC board monitors various operating parameters including high pressure, auger gearmotor amperage limits,
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:
HI AMPS: The PC board monitors the amperage of the auger motor. Should the gear motor experience current
draw above the allowable limit, 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.
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, but the water feed solenoid will remain energized. Should water return, it will fill to the normal low sensor
and the machine will resume normal operation. The error will clear automatically.
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.
Hard Error:
HI AMPS: If a second hi-amp error occurs within 1 hour of the initial hi-amp error, the icemaker 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.
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 flush. 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 refill with water 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.

Starting Procedure
Normal Operation – Stage 1
Power is supplied to L1 of the control board, the POWER LED light begins flashing. 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 lit. 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 fill 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 icemaker is now in a normal ice making mode. The icemaker will produce ice until the bin level control in the
ice dispenser is satisfied.

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
Icemaker production capacity can only be determined by weighing ice produced in a specific time period.
1. Remove top panel and hopper lid of unit.
2. Weigh and record weight of container used to catch ice.
3. Run icemaker 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
Total test time in minutes
= Production capacity/24 hr. period
9. Calculated amount per 24 hours should be checked against rated capacity for same ambient and water
temperatures in Ice Production Table (see page 6).
