The BF-60-MIL-UPSD has been designed to provide more flexibility, and
therefore more options, for those who work within the requirements
and protocol of cold-chain transport.
The Units can be used in the following manner and will run 24/7:
In any mode of transportation, including vehicles,
planes, boats, etc., Units can be plugged into a 12VDC to
28VDC supply (for example, vehicle’s cigarette lighter).
In a clinical setting, including temporary clinics or
established hospitals, Units can be plugged into a 110VAC
60 Hz/240 VAC 50 Hz supply (a standard wall outlet).
In any setting, when the Unit is connected to the
Detachable Battery Backup System (DBBS) and the
primary power source becomes lost, the Unit will
automatically draw from the DBBS 12VDC supply. (DBBS
must be pre-connected to the Unit.)
See SECTION 5 for more information on the DBBS.
Basic Operation
WARNING
BioFridge portable refrigerators and freezers are powered by
electric current; not taking proper steps to ensure safety can
potentially injure or kill. ANY installation, cleaning, or
troubleshooting must be conducted with the electrical power
source disconnected from the BioFridge Unit. (110VAC, 12VDC)
▪After receiving the BioFridge unit from the shipper, please wait 24
hours before turning it on. The oil in the compressor needs time to
settle. Ensure unit is upright and out of the box.

▪Never operate the BioFridge unit at a tilt exceeding 30 degrees for an
extended period of time. The oil reservoir will not lubricate the
compressor motor properly at angles above 30 degrees and damage
may result to the compressor.
▪When the BioFridge is plugged into the Detachable Battery Backup
System (DBBS) and running on the DBBS’s 12VDC system, the Unit will
operate for up to 18 hours as a portable refrigerator, and for up to 9
hours as a portable freezer.
▪Whenever possible, pre-cool the refrigerator and its contents in
advance using a 110-Volt AC power source (a typical wall outlet in the
USA and Canada) before taking it off the AC power grid (unplugging it
from the wall outlet).
▪BioFridge units are equipped with a GREEN light indicator located on
the control panel. The compressor is running when this light is
illuminated.
▪At least 4 inches of ventilation space around a BioFridge unit is
recommended in order to properly dissipate heat. Keeping the unit
well-ventilated will improve performance.
▪Whenever possible, avoid operating the BioFridge unit in direct
sunlight; doing so will decrease the unit's efficiency.
▪Many factors can affect the efficiency of the Unit. Factors include:
· the ambient temperature outside the Unit
· the ventilation area around the Unit
· the number of items inside the unit
· the starting temperature of the items put in the unit.
Placing warm items inside the unit in hot ambient temperatures, and
leaving the lid open, will negatively affect the performance.
▪Using the Unit is the best way to learn its capabilities.

▪The recommended way to clean the BioFridge is with a container of
warm water, a sponge, and a bottle of all-purpose cleaner. Never
submerge a BioFridge unit in water.
▪If the BioFridge is used as a freezer for long periods of time
(approximately 2-3 months) the Unit should be periodically defrosted
with its contents removed.
▪Never empty water out of the Unit by turning it upside down. Doing so
can cause water to collect in the top of the cowl. Remove excess water
with a sponge.
Storing
To store the Unit:
1. Ensure DBBS is plugged into the 110VAC (or wall outlet).
2. To ensure battery voltage does not drop to an excessively low
voltage, leave the DBBS plugged into the 110VAC, whenever
possible. If not available, power up once every 1 to 2 weeks.
3. Unplug the umbilical cord (between the BioFridge and DBBS).
4. Open the lid to defrost and vent the Unit.
5. Once defrosted, remove excess water with a sponge.
6. Store Unit with the lid slightly open.
WARNING
BioFridge portable refrigerators and freezers are powered by
electric current; not taking proper steps to ensure safety can
potentially injure or kill. ANY installation, cleaning, or
troubleshooting must be conducted with the electrical power
source disconnected from the BioFridge Unit. (110VAC, 12VDC)

SECTION 5
Detachable Battery Backup System (DBBS)
When the DBBS and BioFridge are connected to each other and each is
connected to the 110VAC (wall outlet), the BioFridge has two power sources
to draw from. The primary source will be the 110-Volt AC from the wall
outlet. The secondary source will be the 12-Volt DC from the DBBS System.
The BioFridge will run exclusively on 110-Volt AC until the power is
interrupted (for example, by black or brown outs). When AC power is
interrupted, the BioFridge will automatically switch to draw from the DBBS.
DBBS Capacity:
12 VDC
40 Amp Hours
Output:
11.5 VDC
13.8 VDC
Input:
110V 60Hz
240V 50Hz
Ambient Temperature Range: -18Celsius to 55Celsius
Note: The capacity of the DBBS may be reduced in extreme low ambient
temperatures. For example, -18Celsius ambient DBBS capacity will be
reduced by 40%.
Service Life of DBBS = 2 years
Preventative Maintenance
DBBS to be changed out every 2-3 years;
Thermostat and Probe to be changed out every 5-6 years.

Charging the DBBS
1) To charge the DBBS, insert 110VAC cord into input AC receptacle
(standard wall outlet.)
2) Note: LED battery charge status RED, GREEN,or both LED’s will
illuminate.
RED = Bulk Charge Rate
RED/GREEN = Absorb Charge Rate
GREEN = Float Charge Rate
2) From a full discharge, 11.5 VDC, the Unit will take approximately 6
hours to recharge.
4) Once the battery charge status GREEN LED is illuminated, the
DBBS is fully charged.
Connection of the DBBS to the BioFridge
1) Place the BioFridge on top of the DBBS. (Note: the control end of
the BioFridge must be in the same orientation as the control end
of the DBBS.)
2) Fasten all 3 over-center latches from DBBS to BioFridge. Ensure
latches are tight (adjust if necessary).
3) Using the 12VDC umbilical cord, connect one end to the input DC
receptacle on DBBS. Connect the other end of the umbilical to the
input DC on the BioFridge.
4) BioFridge is now powered by DBBS.

5) On Board Power Supply Capacity Status:
Voltmeter indicates the voltage of the DBBS (DC Volts)
13.2V –12.1V = 100% - 35% capacity
12.1V –11.8V = 35% - 10% capacity
11.8V –11.6V = 10% - 0% capacity (Plug into AC power supply)
RUN TIME*
Refrigerator: 18 hours; -12to 10Celsius
Freezer: 9 hours; -18Celsius
*This run time is calculated in an ambient temperature of 75Fahrenheit. Run time may be
less in higher ambient temperatures.
Using the BioFridge DBBS as a secondary power supply
1) Attach the BioFridge to the DBBS
2) Connect the 12VDC umbilical cord from DBBS into BioFridge
3) Connect one 110VAC cord to AC input receptacle on BioFridge
4) Connect one 110VAC cord to AC input receptacle on DBBS
5) The BioFridge will run off the 110VAC supply (wall outlet)

625 VENTURE STREET, SUITE A, ESCONDIDO CA 92029
TEL [phone] * FAX [phone]
15
6) The DBBS will charge from the 110VAC supply and remain at 100%
charge
7) If the AC power source is lost (for example in a black or brown
out), the BioFridge will automatically switch to the 12VDC supply
from the Detachable Battery Backup System.
8) Once 110VAC supply has been restored, the BioFridge will
automatically switch back to drawing from the 110VAC supply.
9) No disconnection of AC or DC cords is required. AC and DC cords
can stay connected to the BioFridge and DBBS.
RUN TIME*
Refrigerator: 18 hours; -12to 10Celsius
Freezer: 9 hours; -18Celsius
*This run time is calculated in an ambient temperature of 75Fahrenheit. Run time may be
less in higher ambient temperatures.
