At the end of the appliance life
When disposing of your appliance, use an authorized disposal site. The refrigerant must be completely drained and
collected by an authorized technician for recycling prior to disposal. Check with your local Environmental Agency 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! Wash the inside and outside of the appliance with luke 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
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.), and avoid prolonged exposure to
direct sunlight. 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 it’s side or on end, it should be allowed to stand in the normal
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 OR 24 VDC POWER
SOURCE, SUCH AS A BATTERY OR CHARGE CONTROLLER.
THE UNIT WILL AUTOMATICALLY OPERATE ON EITHER 12 OR 24 VDC.
THE USER DOES NOT NEED TO MAKE ANY ADJUSTMENT.
ATTENTION: Polarity is important in wiring this DC appliance. Be sure that positive terminal of the battery or
charge controller coincides with the positive wire to the compressor, and the negative terminal of the
battery or charge controller coincides with the negative wire to the compressor. The leads should be
connected using cable shoes and screwed connections. Joined leads should be avoided.

Low Voltage Disconnect
The compressor electronics includes a low voltage
disconnect feature. If the input voltage to the
appliance falls below 9.6V (in 12 V mode) or 21.3V
(in 24 V mode), the compressor will shut-off. Once
the voltage increases above 10.9V (in 12V mode) or
22.6V (in 24V mode), the compressor will resume
normal operation.
This feature is designed to protect the system battery
from experiencing too low a depth of discharge.

OPERATION
The SunDanzer refrigerating appliance, like any battery-powered 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 or 24 VDC power source, the compressor will automatically
turn on and the cabinet will begin cooling. Allow the cabinet to cool for at least 4 hours prior to adding foodstuff.
Temperature Control
The temperature within the appliance is controlled by the thermostat situated on the lower front of the cabinet. When
you first start the appliance we suggest that you turn the thermostat to a medium setting by using a coin that fits the
groove. The correct internal temperature setting can be found by measuring the temperature of the central or middle
portion in the appliance.
0 = refrigerator setting
1-5 = freezer settings

Internal Temp. (oC)
Internal Temp. (oF)

-18oC
Setting = 5 (coldest)
The unit will run a few degrees colder at high elevations.
Adjustments
As the ambient temperature changes from summer to winter, it may be necessary to adjust the thermostat to achieve the
proper internal temperature setting. If the room/ambient temperature approaches the appliance’s internal operating
temperature, the appliance will not function as it should. The appliance will tend to run colder during these conditions
and it may be necessary to turn the thermostat to a warmer setting (towards the ‘min’). If the room/ambient temperature
exceeds 100oF (38oC), the appliance will not function as it should. The appliance will tend to run warmer and it may be
necessary to turn the thermostat to a colder setting (towards the ‘MAX’ setting).
Opening and Closing the Lid
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.
Overfilling and/or unlevel installation of the appliance will prevent a good seal. It might be hard to open the lid
immediately after the lid is closed. This is due to air contraction in the cabinet. This pressure difference will equalize
in a few seconds.
Loading
Do not over fill the appliance more than ½ in. (1.25 cm) below the edge of the casing.
A battery-powered refrigeration appliance has a cooling capacity lower than typical AC units. Because the compressor
is small, the unit runs more efficiently, but lacks the ability to cool large, warm loads as quickly. To assist the cabinet in
cooling large loads quicker, keep the cabinet full of product (or containers of water). It will also help to cool your food
quicker if your food is packaged in smaller containers rather than large ones. Food packages more than 2 inches thick
will cool slowly. Avoid placing warm foodstuff in contact with cold foodstuff.

Rev. 05/21/08
DEFROSTING
•
Before any cleaning or repositioning is carried out, you must DISCONNECT the appliance from the electrical
power supply.
Freezer Defrosting
The appliance compartment will become progressively covered with frost. This should be removed periodically with a
plastic scraper (provided with some units). However, when the ice becomes very thick on the interior walls, complete
defrosting should be carried out. Perform this operation when the appliance is empty and disconnected from the power
supply.
Never use sharp metal tools to scrape or chip off frost from the interior compartment as this could
damage the appliance beyond repair. Do not use heat sources, such as electric or gas heaters to
complete the defrost process.
To carry out complete defrosting:
1. Disconnect the appliance from the electrical supply.
2. Remove any stored food and store in coolers, or wrap in several layers of newspaper and store in a cool place.
3. Leave the lid open.
4. Remove the plug from the defrost water drain located in the bottom interior of the cabinet.
5. To accelerate the defrosting process, place a bowl of hot (not boiling) water inside of the appliance and close the
lid.
6. The defrost water can be collected by placing a pan under the defrost drain located on the exterior bottom front of
the cabinet.
7. When defrosting is complete, wash and dry the interior thoroughly. Be sure to replace the plug on the defrost
water drain.
8. Reconnect the appliance to the electrical supply and leave running (while empty) for at least 2 hours allowing the
interior to cool sufficiently.
9. Replace the previously removed foodstuff.
ATTENTION: A rise in temperature of frozen food products during defrosting may shorten
their safe storage life.
CLEANING
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. 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.
A thermostat controls the compressor and you may hear a 'click' when the thermostat cuts in and out.

Energy Saving Advice
•
•
•
•
•
•
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)
Avoid unnecessary frosting in the cabinet by packing all food and liquids in airtight packages or containers.
Always keep foodstuff stored in tightly sealed packaging or containers, and allow some space for air to circulate
around each item.
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.
Ensure there are no obstructions preventing the lid from closing properly and forming a tight seal.
TROUBLE SHOOTING
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.
SYMPTOM
Appliance connected
to power, but does not
operate
Appliance is
operating, but the
interior is not cold.
The lid will not open.
Excessive frost and ice
has built up.
Noise
SOLUTION
• Check if 12 or 24V DC is present at the appliance. If not check all connections
and the system battery voltage.
• Check that the polarity is correct “+” is connected to “+” and “–“ to “–“.
• Check the fuse. If blown, replace with a new one.
• The main common problem with installations is voltage drop to the compressor
which causes the unit to fail to start due to “Low Voltage.” Typically a
connection is not as tight as it should be, or the wire size to the compressor is too
small. The low voltage problem occurs at the instant of start-up and is
sometimes difficult to detect with a volt meter because the event is very quick
(<100 ms)
• Allow the appliance at least 4 hrs from initial turn-on to become cold.
• Check that the thermostat control knob is turned to the correct setting relevant to
room/ambient temperatures.
• Check that the room/ambient temperature is not approaching the internal
operating temperature and does not exceed to 100oF (38°C).
• Has too much warm foodstuff recently been placed in the cabinet? If so, it is
normal to not be cold and it will take time to return to temperature.
• Does the cabinet have adequate ventilation around the side walls allowing it to
transfer heat properly? (See Installation Section).
• Has the lid just been opened? If so leave for a few minutes to allow the air
pressure to equalize and try again.
• Is the weather hot and humid? If so, this will increase the rate of frost build up in
the cabinet.
• Ensure that foodstuff is properly packaged.
• Check that the lid is closed and has a good seal, and that nothing is preventing
the lid from closing properly.
• Large quantities of food have recently been placed in the cabinet/and or the lid is
frequently opened.
• Ensure that advised periodic cleaning has been carried out.
• Refer to 'Normal Operating Sounds'
