Controller operation
In normal operation the controller displays cabinet temperatures
in degrees C (default) or user-selected degrees F. Degrees C
temperatures are displayed to 1 decimal point.
Rocker buttons to the right of the temperature display control all
programming functions.
The controller is pre-programmed with a -25 C (-13 F) set point which
provides a compressor cut-in at -23 C (-9 F) and cut-out at
-25 C (-13 F). The controller set point can be raised to -15 C (+5 F)
for nourishment applications where a lower temperature is not
desired (i.e. ice cream). Follow instructions for changing temperature
cut-out below.
All set points have a 2 C differential. The 2 C differential means that with a -25 C set point, for example, the
compressor will turn off at -25 C (-13 F) and turn on when it reaches -23 C (-9 F).

Operation
The temperature controller and probe indicate when the refrigeration system is required to turn on and off.
The refrigeration system removes heat from the cabinet interior and rejects it to the surrounding room air. When the
cabinet interior temperature reaches +2 C (+4 F) above the controller set point, the probe signals the controller to
turn the refrigeration system on. The normally-open controller contacts 4 and 5 close and energize the evaporator
and condenser fan motors, compressor and door heater. The snowake and fan LED's on the controller will come
on to indicate the refrigeration system is on. The compressor uses a current-style starting relay and a starting
capacitor to start the compressor motor.
When the cabinet interior temperature falls to the set point, the probe signals the controller to turn the refrigeration
system off. The controller contact 5 reopens, which de-energizes the condenser fan motor and the compressor. The
snowake LED will go out and the fan LED will remain on.
Any accumulated frost on the evaporator coils melts during the defrost cycle. The condensate drains to a drain pan
mounted along the condensing unit. The heat from the condensing unit evaporates any condensate in the drain
pan.
Temperature control
The temperature control system is preset by the factory to maintain a cabinet temperature of -23 C (-10 F). If
desired, the cut-out temperature can be raised as high as -15 C (5 F) by following the instructions on page 6
for changing the temperature set point. The 2 C cut-out differential will be maintained regardless of the controller
set point.
Defrosting
The FZR series undercounter freezers control frost accumulation on the evaporator through automatic timed defrost
cycles. The defrost cycle is initiated by the temperature controller every 6 hours. Contacts 4 and 5 on the controller
open and the refrigeration system is turned off. Contact 2 is closed and the defrost heater is energized. The melting
snowake LED on the controller will come on, and the temperature display will read: “dEF” to indicate the freezer is
in the defrost cycle.
The heaters warm the evaporator coil and drain pan to melt the frost and drain the water to the condensate pan.
The temperature controller monitors evaporator temperature using a probe embedded in the coil. The controller
terminates the defrost cycle when the evaporator temperature reaches +5 C (+41 F) or after 12 minutes of defrost
time, whichever occurs rst. As the defrost cycle terminates, the controller de-energizes the heater and restarts
the compressor and condenser fan. The snowake LED on the controller will come on to indicate the refrigeration
system is running.
There is a 5 minute delay before the evaporator fan motor is re-energized. The fan LED on the controller will
come on to indicate the fan is running and the temperature display resumes displaying cabinet temperature. A
defrost cycle can be initiated manually at any time by depressing and holding the melting snowake button for
approximately three seconds. As a safety feature, a temperature safety switch mounted on the evaporator will turn
off the defrost heater if the temperature of the evaporator reaches +27 C (+80 F) regardless of controller operation.
The FZR series freezers have been designed specically for the storage of temperature–critical medications. Other
storage applications may require modications of the factory-programmed defrost cycle settings. Please consult
Follett technical service if defrost modication is needed.
Note: Storage of products with very low volumes may require additional product insulation.
Note: Serial numbers below C57095 were programmed with defrost cycles every 2-4 hours terminating at
+5 C (+41 F) or after 15 minutes, whichever came rst. If you are experiencing problems with frost on any of
these earlier units, please call Follett's technical service department at [phone] or [phone] for
a programming key to update your unit to the most current program settings.
Cleaning
Interior – Using a sponge or soft cloth, clean unit with a non-abrasive, non-chlorinated, all-purpose detergent.
Exterior – Wipe exterior with a soft cloth in the direction of grain as needed. Stainless steel polish may be used to
enhance the nish of the unit.
Use only non-chlorine-based cleaners. Cleaners containing chlorine can cause staining and pitting of the
stainless steel.

Wiring diagram
Refrigeration system
The FZR series -20 C (-4 F) freezer refrigeration system is designed to give many years of trouble-free service.
Except for routine cleaning of the air-cooled condenser and related parts, the refrigeration system requires no
service or maintenance. The system uses a thermostatic expansion valve and is critically charged. Access ttings
are provided for ease of service. However, the connection of refrigeration service hoses to the ttings will almost
invariably result in a signicant change in the system charge. This change can adversely affect the performance
of your freezer. Therefore, Follett recommends that if hoses are ever connected to the refrigeration system for
service, the refrigerant should be recovered, the system evacuated, and recharged by weighing in the correct
refrigerant charge.
Note: Do not charge the system by pressures.
Checking refrigeration system pressures
1. Remove the rear access panel (Fig. 10).
2. Turn the power switch to the on position.
3. Following the instructions on page 6 verify that the temperature controller is set to the original factory
cut-in setting of -23 C (-9 F).
4. Allow the freezer to operate and stabilize at least 60 minutes, verifying the cut-out temperature is
being reached.
5. Connect refrigerant hoses to access ttings and measure air temperature at condenser intake grille.
6. Verify correct pressures with the temperature chart below.
7. Troubleshoot refrigeration system as needed.
Note: Do not attempt to obtain correct refrigeration pressures by adjusting the system charge.

Alarm operation facts
The back-up battery will continue to provide alarm protection during power failure but will alarm ONLY if temperatures go out
of the selected range. During power failure the alarm face will be dark but temperatures can be read by pressing the RESET
button.
Low battery is indicated by 3 decimal points in temperature display (3.6.f.).
To see the highest or lowest temperature since last reset, press the button until “HI” or “LOW” appears. To clear log value, press
RESET.
Because the temperature alarm display simulates the true temperature of stored medications rather than the air temperature
inside the refrigerator, we suggest that staff refer to the alarm display to log temperatures for JCAHO compliance.
