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

• IMPORTANT: The skin of the refrigerator is the condenser and will become warm when the compressor is running. There should be adequate ventilation space between the refrigerator and neighboring walls. At least 3 inches (7.5 cm) is recommended.
• For best efficiency, place the refrigerator in a cool location and avoid prolonged direct sunlight on the appliance.
• Level the refrigerator using the adjustable feet or wood shims if necessary. This is necessary for the thermostat to function properly and for condensation to drain correctly.
• Always keep the air vent openings of the compressor housing cover (Lower right side or rear) free from dust and obstructions.

Installing the door handle
Some models may ship without the door handle installed. If this is the case, the handle and mounting hardware will be located inside the refrigerator.
Let oil settle

• The appliance should be left off for 30 minutes after positioning before it is turned on, 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 24 hours before turning it on.

ELECTRICAL DC CONNECTION

• The positive wire is colored Red or is black with a red stripe. The negative wire is black.
• THE APPLIANCE MUST BE CONNECTED TO A 12V OR 24 VDC POWER SOURCE ONLY, 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.
• This unit will not operate directly from a PV solar module. Contact SunDAnzer if you prefer this option.
• THIS APPLIANCE MUST NEVER BE CONNECTED DIRECTLY TO ANY AC (Alternating Current) POWER SOURCE!
• If the polarity is reversed, the unit will not be damaged, but will not run. If the unit is equipped with a light, the light will operate even with reverse polarity
• Since there is no established standard DC plug, the power cord has simple ferrel terminations. The user must provide a meaning of connection this wire to the power source. Using wire nuts, or adding a ring or spade terminal is common.
• This connection should not become hot when the units is running. If it does, rework the connection to insure better conductivity.

BEFORE SWITCHING ON, LET COMPRESSOR OIL SETTLE

• The appliance should be left off 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.

Electronics Diagram (Direct Battery connection example)

Fuse
A fuse is required in order to protect the wiring. A standard automobile fuse is recommended and the fuse should be wired to the positive (“+”) side of the system close to the positive battery terminal. For 12V operation, use a 15A fuse, and for 24Voperation use a 7.5A fuse.

ATTENTION: A 6 ft. (2 m) power cord is supplied. If a longer connection cable is necessary, the cable cross section (or gauge) must be equal to or greater than the cable sizes recommended on the following table.

The most common customer call is related to using inadequate wiring such that the compressor will experiences a low voltage situation at start-up and not run.
Low Voltage Disconnect
The compressor electronics includes a low voltagedisconnect feature. If the input voltage to theappliance falls below 9.6V (in 12 V mode) or 21.3V (in 24 V mode), the compressor will shut-off. Oncethe voltage increases above 10.9V (in 12V mode) or22.6V (in 24V mode), the compressor will resumenormal operation.
This feature is designed to protect the system battery from experiencing too low a depth of discharge.

| 12V Operation| 24V Operation
---|---|---
Cut- in| 9.6V| 21.3V
Cut – out| 10.9V| 22.7V

OPERATION

Once the wiring is complete and the refrigerator has 12 or 24VDC available, the unit will turn on automatically. The thermostat is also an on/off switch for the unit. When the dial is fully counter clockwise, the fridge will be off.
Initial Cooldown
Once on, the refrigerator will reach operating temperature in about 20 minutes. We recommend letting the fridge run at least 30 minutes before placing food or beverage inside. Large warm loads can take hours to cool.
Ambient Temperature/Climate
This refrigerator is designed to operate in a wide ambient temperature range. The certified range is 41F (5C) to 110F (43C).
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 1 hours prior to adding foodstuff. To save energy and reduce cost, the units do not have running lights.
Baskets
Larger models include baskets. These baskets can be configured to hang form the top lip of the refrigerator or can stack in the bottom by adjusting the plastic tabs on the baskets.
Temperature Control
The temperature within the appliance is controlled by the thermostat situated on the lower front or side of the cabinet. When you first start the appliance, we suggest that you turn the thermostat to a medium setting. On some models, a coin can be used to turn the dial. The best way to measure the average internal temperature is to measure the temperature of a bottle of water located near the middle of the refrigerator. 39F (4C) is a normal operating temperature. The refrigerator will draw noticeably less power at warmer settings. A good initial operating position of the thermostat is nearer the warm end of the range.
Normal Operating Temperatures

The unit will run a 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.
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! Leave some space at the top so the door can always fully close. 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 (5cm) thick will cool slowly. Leave air spaces between food items for quicker cooling. Items in contact with the interior walls will cool much faster and can freeze at if the thermostat is set to the coldest setting.
Shutting down or taking unit Out of Service
Turning the thermostat fully country clockwise will turn the unit off. If the unit is to be off for an extended period (more than 6 hours), the interior should be thoroughly cleaned and dried. It is recommended to leave the lid slightly open to provide ventilation.
DEFROSTING (In freezer models only)

• 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 AND MAINTENANCE

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.
END OF LIFE
While this refrigerator should last many year, at some point it will be time to dispose of the unit. Be sure to use normal and proper disposal methods based on your local. 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!
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.

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)
Appliance is operating, but the
interior is not cold.| • 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 100° F (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).
The lid will not open.| • Has the lid just been opened? If so leave for a few minutes to allow the air pressure to equalize and try again.
Excessive frost and icehas built up.| • 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.
Noise| • Refer to ‘Normal Operating Sounds’
