At the end of the appliance life
When disposing of your appliance, use an authorized disposal site. The refrigerant must be completely drained and

for recommendations on recycling this appliance in your area. Remove the electrical connection wiring and also
ensure that the lid is removed to prevent young children from being trapped inside. DANGER OF
SUFFOCATION!
INSTALLATION
Unpacking and Cleaning
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
warm water and a mild soap or detergent. 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 of BFR105 Refrigerator
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. 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). Exposure to sunlight will cause
adverse effects to performance. This appliance uses the exterior walls to transfer heat from the inside of the cabinet.
Ensure that there is adequate space between the appliance and neighboring walls or large objects. A minimum
spacing of 3 inches (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
ELECTRICAL DC CONNECTION
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
2
operating position for 12 hours before turning it on.
THIS APPLIANCE MUST NEVER BE CONNECTED DIRECTLY TO
ANY AC (Alternating Current) POWER SOURCE!
THE APPLIANCE MUST ONLY BE CONNECTED TO A 12V NOMINAL
PV ARRAY.
Making the DC Connection
Make sure the wiring between the solar panel and refrigerators is secure to prevent excessive voltage drop, which
can prevent the compressor from starting or running efficiently. The red strip on the wire from the cabinet indicates
the “+” (positive) wire.
CONTACT MANUFACTURER FOR USE WITH OTHER POWER SOURCES. This refrigerator can operate
on a 12 V battery, but a fuse is necessary between the battery and refrigerator. Please contact SunDanzer before
connecting this appliance to a power source other than a 12V solar panel
Fuse
Not normally required for PV direct application, unless array short circuit current (Isc) exceeds wire capacity.

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 solar panel, the compressor will automatically turn
on and the cabinet will begin cooling.
Holdover
Once fully frozen (4-5 days of full sun), this unit will remain cool for about 4-5 days without sun. If better
performance is required, contact SunDanzer about an East-West PV configuration.
Temperature Control
Temperature control is fully automatic and not adjustable by the user.
Opening and Closing 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 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 effect performance. Overfilling and/or unlevel installation of the
appliance will prevent a good seal.
.
NEVER USE EXCESSIVE FORCE ON THE HANDLE TO OPEN THE LID!

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 which
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.
Loading Appliance
Since cooling occurs only in good sun conditions, it is best to insert warmer product in the morning.
CLEANING
Defrosting
It may be necessary to occasionally defrost this appliance. Use a towel and warm water. This might take several
hours.
Internal Cleaning
Wash the inside of the appliance with luke warm water and a mild soap. Never use abrasive or corrosive cleaning
agents, steel wool, scouring sponges, chemical cleaning agents, or highly perfumed cleaning products to clean the
interior as these will damage the surface and leave behind a strong odor. A sponge, towel, or soft brush is
recommended. Washing with a mixture of two table spoons of baking soda to 1 quart (1.14L) warm water is
recommended. After cleaning, thoroughly rinse and dry.
External Cleaning
Wash the outside of the cabinet with warm water and a mild soap or detergent. Do not use abrasive or corrosive
cleaning agents, chemical cleaning agents, steel wool or scouring sponges to complete this task as it may cause
damage to the surfaces.
HINTS & TIPS
Normal Operating Sounds
• You may hear faint gurgling or bubbling sounds when the refrigerant is pumped through the refrigerant
coils.
• When the compressor is on, the refrigerant is being pumped around and you will hear a whirring sound or
pulsating noise from the compressor.
Peak Performance Tips
• Do not install the appliance close to sources of heat, such as a stove, boiler, heater, chimney, etc, and avoid
exposure of the appliance to direct sunlight.
• Locate the appliance in a cool well-ventilated room and make sure that the air vents of the compressor
housing cover are not obstructed. Also allow adequate spacing around the cabinet for air circulation (3in.
or 7.5cm)
• Do NOT add external insulation to the sides or bottom of the cabinet, as this will severely hinder the
condenser performance
• 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 to run unnecessarily often.
TROUBLESHOOTING
Before contacting a service technician, SunDanzer or your local product dealer, check the following points. If you
call out a technician to a fault listed below, or to repair a fault caused by misuse, abuse, or faulty installation, a
charge will be made even if the appliance is under warranty.
