Controller operation
In normal operation the controller displays cabinet temperatures in
degrees C (default) or user-selected degrees F.
The controller is pre-programmed with a -35 C (-31 F) set point
which provides a compressor cut-in at -33 C (-27F) and cut-out at
-35 C (-31 F). The controller set point can be raised to -25 C
(-13 F) when a lower temperature is not desired. Follow instructions
for changing temperature cut-out below.
All set points have a 2 C differential. The 2 C differential means that
with a -35 C set point, for example, the compressor will turn off at -35
C (-31 F) and turn on when the cabinet reaches -33 C (-27 F).
This temperature may not reect the temperature of the blood products in the freezer. The temperature of the
blood products will be reected on the recorder chart and the recorder's digital temperature display. At times there
may be a difference between the two displayed temperatures. Adjust the controller SET value to achieve your
desired blood product temperature as displayed on your chart recorder.
To display temperature cut-out
STEP INPUT DISPLAY
1 Press and release SET Current cut-out temperature will display for approximately 5 seconds.

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, the fan LED will remain on.
Any accumulated frost on the evaporator coils melts during the defrost cycle. Freezer products will remain at or
below -20 C (-4 F) 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 -33 C (-27 F). If
desired, the cut-out temperature can be raised as high as -25 C (-13 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 FZR5-PL undercounter freezer controls frost accumulation on the evaporator through automatic timed defrost
cycles. The defrost cycle is initiated by the temperature controller every 4 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 heater warms 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 25 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 10 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.
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.
!

Annual cleaning
Removal of dust and other particulates from air intake areas and the
condenser is important for proper operation. Some environments with
large amounts of dust may require more frequent cleaning.
1. Disconnect power to unit by turning switch on the lower
front panel to the OFF position, switching circuit breaker
to OFF position, and removing power cord from receptacle.
2. Remove lower front panel (Fig. 6.1).
Note: Front louvered panel may be completely removed for
easier cleaning by disconnecting the controller wiring plugs from
the freezer.
3. Remove drain pan (Fig. 6.2).
4. Clean drain pan with a non-abrasive, non-chlorinated
all-purpose detergent.
5. Reinstall drain pan.
6. Use a vacuum cleaner with brush attachment to clean
condenser through lower front panel and compressor
motor and related parts through lower rear panel.
7. Reinstall lower front panel.
Service
Latch adjustment
To adjust for proper latch engagement
1. Loosen striker plate mounting screws (Fig. 7.1).
2. Move striker plate up or down as required and tighten screws.
3. Test operation of latch.
To adjust for proper gasket seal
1. Loosen striker depth adjustment screw (Fig. 7.2).
2. Adjust stop in or out and tighten screws.
3. Test operation of latch.
Door gasket replacement
1. Remove existing gasket from mounting track.
2. Verify mounting track is free of any remaining gasket material.
3. Align new gasket with mounting track and press rmly in place.
4. Open and close door, checking for proper gasket seal without
pinching against freezer.
5. Adjust latch and or striker as necessary for proper door closure.
Slide-out compressor tray
Follett’s slide-out compressor tray allows technicians to partially slide
the condensing unit from the freezer back without cutting refrigerant
lines.
1. Remove rear panel (Fig. 8.1).
2. Remove two bolts securing condensing unit to freezer base
(Fig. 8.2).
3. Gently slide condensing unit out (Fig. 8.3).
Note: Do not put undue strain on the refrigerant lines.

Refrigeration system
The FZR5-PL -30 C (-22 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. 8).
2. Turn the power switch to the on position.
3. Following the instructions on page 5 verify that the temperature controller is set to the original factory
set point cut out setting of -35 C (-31 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.
