Operation

Preventive maintenance

Periodic cleaning 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 of the ice machine system, in
most cases, should be performed by your facility’s 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.

Weekly exterior care

The exterior may be cleaned with a stainless cleaner such as 3M* Stainless Steel Cleaner & Polish or equivalent.

* 3M is a trademark of 3M Company.

Service

Ice machine Operation

Follett’s ice machine 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. 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 Follett 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 (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 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 over­torque 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.

Electrical control system operation

The wiring diagrams which follow illustrate the circuitry of 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.

Follett ice machines used on top of an ice storage bin have a slightly different circuitry. The operational and diagnostic
stages for these ice machines will be otherwise the same as Stages 1 - 10 that follow.

Circuitry notes

When the ice machine is used with a dispenser it receives power from two sources – the main power supply and
the bin control signal power from the dispenser. Disconnect both power sources 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 29 bar (425 PSI) and closes at 20 bar (287 PSI) (auto reset).

Compressor switch should read open in on position.

Compressor start relay is position sensitive. See label on start relay for proper orientation.

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.

Normal operation – Stage 1

Power is supplied to L1 of the control board. The ice level control in the dispenser is closed and calling for ice,
completing the bin signal circuit to the control board. The control board will now go through the start-up sequence.
Less than 30 seconds will elapse as the water sensor located in the  oat reservoir checks for water in the reservoir.
The bin empty LED (B-E), and power LED (PWR) will be on.

The water sensor veri es water in the  oat 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. The compressor is started with the start winding being energized through the normally closed contacts of
the potential relay, starting capacitor, and the run capacitor. The PWR, BE and WTR LED remain on.

Normal operation – Stage 3

After the initial high current draw drops off, the gearmotor start relay contacts open, dropping out the start winding.
As the compressor comes up to normal running speed, the compressor start relay contacts open and the starting
capacitor drops out. The start winding remains energized through the run capacitor. The ice machine is now in a
normal icemaking mode. The ice machine will begin to produce ice and continue to produce ice until the bin level
control in the ice dispenser is satis ed. The PWR, B-E, DR, C and WTR LEDs are all on.

25

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 ice machine 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. The bin timer
LED (BT) comes on, starting the twenty minute off cycle time delay.

Diagnostic sequence – Stage 7

The 20 minute error LED (20M) is on, indicating that the control board has sensed an over-torque condition (above

2.5 AMPS on the gearmotor). The 20M LED remains on for 20 minutes after an over-torque condition has occurred.
The ice machine remains off as long as the 20M LED is on. When the 20M LED goes off, the control board will try to
go through a normal start-up sequence. The WTR LED remains on as long as the water sensor in the  oat reservoir
senses water.

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 ice machine has experienced an over-torque
condition. If the ice machine runs without problems for 60 minutes and no additional torque errors occur, the 60M LED
goes off and the ice machine continues normal operation.

Diagnostic sequence – Stage 9

The second error (2ND) LED comes on if an over-torque condition occurs while the 60M LED is still lit. The 2ND LED
indicates two consecutive over-torque situations have occurred. The ice machine will be shut down at this time and will
not restart unless the manual reset button is depressed.

28

Diagnostic sequence – Stage 10

If the water level in the  oat reservoir drops to an unacceptable level, the WTR LED goes out, shutting the ice machine
off. Also, the BT LED comes on, preventing the ice machine from restarting for twenty minutes. If water is restored, the
WTR LED comes back on and  ashes to alert the technician that water to ice machine has been lost. The ice machine
restarts at the end of the 20 minute time delay. The  ashing 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 ice machine to other than
factory speci cations will void the warranty.

Model Charge Refrigerant type

MCC400A, C/ET400A, C/ER400A, C/ED400A (air-cooled) 539g (19 oz) R404A

MCC400W, C/ET400W, C/ER400W, C/ED400W (water-cooled) 255g ( 9 oz) 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 non­condensibles 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, 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 rises, evacuate the system again. If the system pressure rises for a second time, check the system for leaks.

Ambients Minimum Maximum

Air Temperature1 10 C/50 F 37.8 C/100 F

Water Temperature2 4.4 C/40 F 32.2 C/90 F

1

Ambient air temperature is measured at the air-cooled condenser coil inlet.

2

Ambient water temperature is measured in the ice machine  oat reservoir.

Ice capacity test

Ice machine production capacity can only be determined by weighing ice produced in a speci c time period.

1. Replace all panels on ice machine.

2. Run ice machine for at least 15 minutes.

3. Weigh and record weight of container used to catch ice.

4. Catch ice for 15 or 20 minutes.

5. Weigh harvested ice and record total weight.

6. Subtract weight of container from total weight.

1440 min. x wt. of ice produced
= Production capacity/24 hr. period
Total test time in minutes

7. Convert fractions of pounds to decimal equivalents (ex. 6 lbs 8oz = 6.5 lbs).

8. Calculate production using following formula:

9. Calculated amount per 24 hours should be checked against rated capacity for same ambient and water

temperatures in Ice Production Tables.
