Installation
DANGER
• Do not tilt any unit further than 30° off vertical during uncrating or
installation
• Refrigeration module area contains mechanical, moving parts. Keep
hands and arms clear of this area at all times. If access to this area is
required, power to unit must be disconnected rst.
The equipment must be transported and handled exclusively in upright position, in observance of the instructions
printed on the packing. This precaution is necessary to avoid contamination of the refrigerant circuit with
compressor lube oil with resulting valve and heat exchanger coil failure and problems starting the electric motor or
the risk of gas leak. The manufacturer is not responsible for any problems due to transport executed in conditions
other than those specied herewith. The equipment is secured to a wooden pallet base, wrapped in a plastic lm
and packaged into a three waves carton box. The equipment must be handled using a fork lift truck or a pallet
truck with suitable forks (fork length at least equal to 2/3 length of unit).

Remote Alarm Connection
These units are equipped with a remote alarm plug for the connection to a remote alarm network.
The remote alarm plug is installed at the back of the cabinet near the main power plug enclosure and it is wired
through a connection cable to the controller board.
Fig. 3
The Remote alarm contact is a Dry contact (low voltage: max 24VAc/VDc, 1A, SELV) and consist of three outputs:
C (Common)/N.O. (Normally Opened Circuit)/N.C. (Normally Closed Circuit).
For the external network connection, fasten directly the pins according to the remote alarm network conguration.
When an alarm occurs the contact relay switches from the N.C. position to N.O.

Controller Operation
In normal operation, the controller will display temperature in degrees Celsius. To change from Celsius to
Fahrenheit requires a programming key. Contact Vector Products Parts Department at 1-855-686-5592 for
part numbers and pricing.
CAUTION! Follett Products LLC does not authorize changing any critical operating parameters
as it can cause improper system operation and/or severe mechanical damage.Changing
operating parameters may result in Follett Products LLC voiding equipment warranty.
Freezers are pre-programmed with a –25 C (–13 F) set point. If desired, the freezer’s set point can be adjusted
within a –25 C to –10 C (–13 F to 14 F) range
All set points have a +2 C (+3.6 F) differential (r0 setting on the controller). The 2.2 C (3.6 F) differential means that
with a 4 C (39.2 F) set point, the compressor will turn off at 4 C (39.2 F) and turn on when it reaches 6C (42.8 F).
It is important to understand that the set point equals the compressor cut out.

8Follett Advantage FZRADV25-LB Freezers
Locking/Unlocking of the Keypad
The temperature controller is defaulted to lock out after 30 seconds without a key being pressed and will display
“Loc”. To unlock the controller press the SET key for 1 second until “UnL” is displayed. The controller is now
unlocked.
Viewing/Adjusting the Set Point
With the controller unlocked, press and release the SET key. The current Set Point will populate. Use the UP &
DOWN arrows to the desired Set Point and again press the SET key to store.
Powering the Equipment ON.
Locate the power switch to the left of the controller and place in the ON position (I).
Controller Set Up
Upon power up your controller will alarm RTC. This is instructing you to program the TIME/DATE.
Press and release any key to silence the alarm.
Check that the controller is not locked (LOC). If locked press and hold any key for 1 second and (UNL) will
DISPLAY.

Follett Advantage FZRADV25-LB Freezers 9
Controllers are preprogrammed to alarm at the following temperature:
FZR: High alarm: –15 C (5 F), Low: –35 C (–32 F)
All alarm points operate off of a set SP +/- (A1/LOW, A4/HIGH) strategy.
Alarms will automatically clear when the temperature rises above/below the alarm value plus the A11 parameter
value (Alarm offset) of 3.
AL on the controller screen reports a Low Temperature Alarm.
AH on the controller screen reports a High Temperature Alarm.
Defrosting
Follett Products LLC freezers and freezers do not require manual defrost as they utilize a hot gas defrost cycle
to keep the evaporator coil frost free. The defrost cycle is typically always terminated when the evaporator probe
(Pb2) reads 8 C.
If the defrost probe (Pb2) experiences a failure, or is out of spec, the MAX time the unit will stay in a defrost cycle
is 15 minutes. If this occurs a dFd alarm will appear.
Upon termination of the defrost cycle, the compressor, condenser fan, and evaporator fan will remain off for
60seconds to allow for the melted frost to drip away from the evaporator coil.
Freezers enable an automatic defrost every 6 hours.
Seeing as the cooling and defrost system are external to the cabinet, the stored product and cabinet temperature
should experience a minimal rise during the defrost cycle.
Door Switch
Each freezer door is equipped with a normally opened mechanical switch that recognizes when the door is opened
or closed. When the controller senses an interruption in the continuity of the door switch circuit, the evaporator
fan(s) and compressor will power down. If the door remains open for longer than 2 minutes the controller will
alternate between the temperature and an audible and visual (id) alarm will appear. Once the circuit is closed the
alarm will clear. If an (id) alarm appears with all doors closed troubleshoot the switch circuit.

Cleaning
Use non chlorine-based cleaners. Cleaners containing chlorine can cause staining and pitting of the stainless
steel.
Disconnect power to unit by turning the power switch off, located on the rear, right hand corner, and removing the
power cord from the receptacle.
The appliance is designed for medications, vaccines and laboratory product storage so it is important to keep
it clean. The equipment is thoroughly cleaned at the factory before being shipped. We recommend, however, to
clean the interior cabinet before the rst start up of the appliance.
Interior Cleaning
Using a sponge or soft cloth, clean unit with a non-abrasive, non-chlorinated, all-purpose detergent. Note: The
air plenum can be removed to clean it, as well as behind it. In addition, the shelves and slides should be cleaned
aswell.
Exterior Cleaning
Wipe stainless steel 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. The glass door and exterior parts may be cleaned with a soft cloth, window
cleaner or other non-abrasive cleaner.
Annual Cleaning
Removal of dust and other particulates from air intake areas and the condenser is important for proper operation.
Environments with large amounts of dust may require more frequent cleaning.
1. Disconnect power to unit by turning power switch off and removing power cord from receptacle.
2. The condenser can be accessed from rear for cleaning.
3. Inspect drain pan for any debris or obstruction in condensate pan.
4. Use a vacuum cleaner with brush attachment to clean condenser, compressor and related parts.
Refrigeration System
The Follett Products LLC 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. Temporary piercing valves are required to work on the refrigeration system. Due to the small charge
size contained within these products, Follett Products LLC does not recommend accessing the refrigeration
system. If a sealed system failure is suspected, Follett Products LLC recommends replacing the cooling system in
its entirety.
