Version: 2.29.2016

[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 that the vaccine compartment stays between 2° C and 8° C at night and on cloudy days.
East/West Array
One of the innovative features of the SunDanzer direct drive system is that the solar panels (provided by others)
shall not face the equator, as is customary, but shall face both east and west. For each BFRV15, half the solar
array shall be mounted with a westward orientation and half shall be mounted with an eastward orientation.
For further information, please see installation guide.

safe voltage.
Installation
Unpacking the unit
Remove all packaging and securing tapes from the appliance.
To avoid injury and causing damage to the appliance, be extremely cautious when using sharp or
pointed tools to complete this task.
Keep children away from the packaging material. DANGER OF SUFFOCATION!
Do not clean the appliance with abrasive or corrosive cleaning agents, steel wool, scouring sponges, or
chemical cleaning agents should not be used under any circumstances.
A sponge, soft brush or towel is recommended.
After cleaning, thoroughly rinse and dry.
You may want to leave the lid open allowing the compartment to ventilate for 20 -30 minutes to get rid
of residual odors.
Check with your local Environmental Agency for recommendations on recycling packaging materials in
your area.
Positioning the unit
The area in which the appliance is to be installed must be relatively cool, dry, and suitably ventilated.
The area must be protected against any beating rain and free of abundant dust.
To ensure proper function, the appliance must be placed horizontally on a flat, firm, and stable surface
resting level on all four supports.
The floor must be sufficiently strong enough to support a fully loaded cabinet.
Adjust the feet or use wood or metal shims to level the appliance if necessary.
Do not place the appliance close to heat sources (heater, stove, boiler, chimney, etc.), and avoid
prolonged exposure to direct sunlight.
This appliance uses the exterior walls to transfer heat from the inside of the cabinet. Do not cover or
insulate the exterior walls
Ensure that there is adequate space between the appliance and neighboring walls or large objects; a
minimum spacing of 7.5cm is highly recommended. This will provide sufficient airflow around the
appliance resulting in more efficient operation and longer appliance lifetime.
Always keep the air vent openings of the compressor housing cover free from dust and obstructions.
Avoid keeping the lid open for extended periods of time or opening the lid too frequently as warm air will
enter the cabinet and cause the compressor run unnecessarily often.
If the unit will not be in service, or needs to be stored for a long period of time after it has been in use,
first let unit warm up, then leave the lid partially open to allow natural ventilation and drying of the
interior.

[4]
Post Installation
The appliance should be left for 2 hours after positioning before it is turned on, in order to allow the
refrigerant oil to settle.
If the appliance has been handled standing on its side or on end, it should be allowed to stand in the
normal operating position for 12 hours before turning it on.
The unit has an on-off switch located in the back.
The on-off switch should remain in the “on” position after the system has been properly installed.
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, the compressor will
automatically turn on and the cabinet will begin cooling.
Allow the cabinet to cool for at least 3 sunny days prior to adding vaccine load. This will ensure that
the appliance has had sufficient time to cool the thermal storage packs.
Holdover
This unit is equipped with thermal storage packs that provide cooling when the appliance lacks power,
such as at night or during cloudy days.
In the case of power failure it is important to maintain observation of vaccine temperature with the
externally mounted thermometer.
The following chart gives the approximate time that the internal temperature will remain within the
acceptable temperature range if the thermal storage packs begin fully frozen:

Temperature Control
The temperature within the appliance is controlled by the sensor situated below the perforated
aluminum floor.
The appliance will automatically detect ambient conditions and no temperature adjustment is
necessary.

[5]
Opening and Closing the Lid
NEVER USE EXCESSIVE FORCE ON INSET HANDLE TO OPEN THE LID!
If the lid does not open easily, wait for 1 minute and try again. This allows time for any possible vacuum
condition to relax.
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 that the lid and the lid seal is free from obstructions and forms a complete seal around the rim
of the cabinet.
The external thermostat wire is designed to be shut in the lid and will not affect performance.
Overfilling and/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 the creation of a vacuum that makes it more difficult to open the lid again immediately.
This is quite normal.
Wait for a few moments until the vacuum has equalized and then open gently. Also, ensure that the
cabinet is not locked.
When the unit is not in use and turned off, recommended to leave the lid open to allow air flow.
Loading Appliance
Before adding vaccine be sure that 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 prior to adding vaccine load.
This will ensure that the appliance has had sufficient 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 each item.

[6]
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.
Defrosting
Defrosting is not necessary for this appliance.
Internal Cleaning
Remove the aluminum floor cover and use dry cloth to absorb any standing water or condensation.
Wash the inside of the appliance with lukewarm water and a mild soap.
A sponge, towel or soft brush is recommended. Washing with a mixture of two tablespoons of baking
soda to 1-quart (1.14L) warm water.
After cleaning, thoroughly rinse and dry.
Drain condensation from unit compartment
External Cleaning
Wash the outside of the cabinet with warm water and a mild soap or detergent.
Remove drain plug for cleaning
