Solar Powered Battery-Free Vaccine Storage
Version: 11.2018

[1]
About your BFRV15
The SunDanzer BFRV15 is a World Health Organization pre-qualified Solar Direct-Drive Battery-Free Refrigerator
designed for vaccine storage. It connects directly to the photovoltaic (PV) solar array and requires no batteries
or charge controllers to operate. Temperatures are maintained using a proprietary phase-change material,
which ensures the vaccine compartment always stays between 2° C and 8° C.
East/West Array
One of the innovative features of the SunDanzer direct drive system is an east/west orientation of the solar
modules (available separately). Two 100-watt modules face east, and two 100-watt modules face west. This
orientation ensures maximum compressor run time. For further information, please see the solar installation
manual.

Health and Safety Guidance
Please ensure you understand all warnings before installing or using the appliance. If you are unsure about any
of the warnings, contact SunDanzer or your local product dealer for assistance.
Prior to Installation
Upon delivery, verify the appliance is complete and was not damaged during transport. Do not connect an
appliance if the electrical supply cables or refrigerant circuit is damaged. Contact SunDanzer or your local
product dealer for assistance.
General Safety
 The appliance is heavy; take care when moving.
 Always power off the unit using the switch on the front of the refrigerator. Wait 5 minutes after
powering off to allow the capacitor to drain to a safe voltage.
 When moving or servicing, disconnect the refrigerator from the solar power.
 Ensure the electrical cord does not become bent and the unit is not placed on top of the cord.
 Do not store any containers with flammable vapors or liquids in or around the appliance, such as organic
solvents, spray cans, gas cans, etc. Danger of explosion!
 Do not use other electrical appliances inside the refrigerator.
 Only use an authorized refrigeration technician to service the appliance. Use of an unauthorized
technician may void the warranty.
 The appliance contains R-134a refrigerant and Polyol Esters lubricant oil in the refrigerant circuit line.
Care must be taken when handling the appliance to prevent damage to the circuit.
Child Safety
 There is DANGER OF SUFFOCATION if a child becomes trapped inside! Keep children from playing in, on,
or around the appliance and securely lock when not in use.
Post Installation
 Allow the appliance to settle for 2 hours before turning on to allow the refrigerant oil to settle.
 If the appliance has been standing on the side or end, allow it to stand in the upright position for 12
hours before turning on.
 The unit has an on-off switch located on the front of the unit. The switch should remain in the “on”
position after installation.
Operation
The SunDanzer refrigerating appliance, like any DC refrigerating appliance, requires care unique from appliances
plugged into an electric utility. Prudent operation is the key to extended service.

Starting the Appliance
 After the appliance has been properly connected to the 12 VDC power source and the sun is shining, the
compressor will automatically turn on and the cabinet will begin cooling.
 Allow the refrigerator to cool for at least 3 days prior to adding vaccines to ensure it has had enough
time to cool the thermal storage packs.
Holdover
 This unit is equipped with thermal storage packs to provide cooling when the appliance lacks power
 In the case of power failure, monitor the externally mounted thermometer.
 The approximate holdover time the internal temperature will remain within temperature range if the
thermal storage packs begin fully frozen:
Days without
power
Ambient
Temperature (° F)
Ambient
Temperature (° C)
7 77° 25°
5 90° 32°
3.5 110° 43°
Temperature Control
 The temperature within the appliance is controlled by a sensor situated below the perforated aluminum
floor. The appliance automatically detects ambient conditions and no temperature adjustment is
necessary.

Opening and Closing the Lid
NEVER USE EXCESSIVE FORCE ON INSET HANDLE TO OPEN THE LID!
 To ensure maximum performance of the appliance the lid should remain closed.
 The lid is fitted with a uniform sealing strip to prevent warm air and moisture from entering the
appliance compartment.
 Be sure the lid and seal are free from obstructions.
 Overfilling or unlevel installation of the appliance will prevent a good seal.
 When the lid is opened, the air inside the appliance becomes slightly warmer and expands. When the
lid is closed again, the air is cooled quickly and contracts. This may lead to a vacuum and difficulty
opening the lid immediately which is normal. Wait for a few moments until the vacuum has equalized
and then open gently.

[4]
Loading Appliance
 Before adding vaccine be sure the internal temperature is within the acceptable range of 2°C to 8°C.
 Allow the cabinet to cool for at least 3 sunny days after initial installation before adding vaccines. This
ensures the appliance has had enough time to cool the thermal storage packs.
 Do not place any vaccine above the marked maximum fill line.
 Always keep vaccines stored in tightly sealed packaging or containers and allow some space for air to
circulate around them.
Cleaning Appliance
Never use abrasive or corrosive cleaning agents, steel wool, scouring sponges, chemical cleaning agents, or
highly perfumed cleaning products to clean the unit as these will damage the surface and leave behind a strong
odor.
 Wash the outside of the cabinet with warm water and a mild soap or detergent.
 Defrosting is not necessary.
 Wipe down or drain condensation from unit compartment weekly. Dry vaccine boxes as necessary.
 Remove the aluminum floor cover and use dry cloth to absorb any standing water or condensation.
 Wash the inside of the appliance with 1-liter lukewarm water and two tablespoons baking soda applying
with a soft sponge or towel.
 After cleaning, thoroughly rinse and dry.

Diagnostic and Repair Procedures
Normal Operating Sounds
When the compressor is on, the refrigerant is being pumped around the cabinet and you will hear a whirring
sound or pulsating noise from the compressor.
Troubleshooting
SYMPTOM
SOLUTION
Compressor is
operating but
will not
cool unit.
 Allow the appliance at least 3 days from initial turn-on to
become cold.
 Verify the cabinet has adequate ventilation around the
sidewalls allowing it to transfer heat properly. (See
Installation section).
 Verify the ambient temperature is not exceeding the rated
temperature range of 5°F (-15°C) to 113°F (45°C).
 Verify refrigerant level is ~198g.Check for refrigerant leaks.
Compressor is connected to power,
but not operating.
 Check if 19 to 22V DC is present at the appliance. If not,
check all connections.
 Check the polarity is correct; “+” is connected to “+”, and “-“
to “-“.
 Verify PV system is assembled improperly.
 Verify ECU connections are correct.
 Check for low power voltage.
The lid will not open.
 Ensure the lock is not engaged.
 Check if the lid has just been opened. If so, leave for a few
minutes to allow the air pressure to equalize and try again.
 DO NOT USE EXCESSIVE FORCE ON THE INSET HANDLE TO
OPEN THE LID!
Digital Thermostat is blinking, but
compressor is not operating.
 See chart on Fault Code Errors for the compressor ECU.
Compressor immediately turns off
(i.e., 1-minute intervals).
 Check capacitor for possible failure.
 Check voltage at capacitor.
Yellow/orange liquid at bottom of
cabinet.
 Check for phase change material leaking.
