IMPORTANT SAFETY NOTES
Congratulations! You have purchased one of the most ecient
refrigeration products available on the market today. The Unique
470L1 solar powered DC fridge is designed to provide years of ef-
ficient trouble-free operation. The design is optimized for energy
savings with an ecient DC compressor and thick insulation.
Before using the appliance, read through this manual carefully
including all the information on safety, installation, operation, and
cleaning. These guidelines do not cover every possible condition or
situation that may occur. Be safe using common sense and caution
when installing, operating and cleaning this appliance. If you are un-
sure about any of these instructions or warnings, contact your local
product dealer or Unique O-Grid Appliances for assistance.
IMPORTANT: After transit where the fridge has been
on its side or back, ensure that the fridge is in a level,
upright position for 12 hours to allow compressor fluids
to redistribute evenly before use.

• To allow the interior to cool down properly, run the fridge for at
least 4 hours empty before adding food.
• This fridge is designed to operate on 24 volts DC ONLY. DO NOT
CONNECT THIS FRIDGE TO AN AC (alternating current) POWER
SOURCE.
• This fridge is designed for domestic use only! It is intended for the
storage of edible/consumable food and drinks. It is not intended
for commercial or industrial use.
• Never use excessive force on the handle to open the door.
• If the room/ambient temperature approaches the fridge’s oper-
ating temperature, the fridge may not function corrently. If the
room/ambient temperature exceeds 100˚F (38˚C) the fridge may
not function correctly.
• A DC powered fridge has a lower cooling capacity than typical AC-
powered appliances. Because the compressor is small, the fridge/
freezer runs more eciently but lacks the ability to cool larger
warm loads as quickly as typical AC-powered appliances.

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 SUF-
FOCATION! 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 doors open allowing the compart-
ments 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 APPLIANCE
The area in which the fridge is to be installed must be relatively cool,
dry, and suitably ventilated. The area must be protected against any
inclement weather (rain, snow) and excessive surface 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 strong enough to support a fully loaded cabinet. Use wood
or metal shims to level the fridge if necessary.
Do not place the fridge 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 fridge
and neighboring walls or large objects. A minimum spacing of 3
inches (7.5 cm) is highly recommended. This will provide sucient
airflow around the appliance resulting in more ecient operation and
longer appliance lifetime. Always keep the air vent openings of the
compressor housing cover free from dust and obstructions.

DC POWER CONNECTION
IMPORTANT: After transit where the fridge has been on
its side or back, ensure that the fridge is in a level, up-
right position for 12 hours to allow compressor fluids to
redistribute evenly before use.
THIS FRIDGE MUST NEVER BE CONNECTED DIRECTLY
TO ANY AC (alternating current) POWER SOURCE!
THE FRIDGE MUST ONLY BE CONNECTED TO A 24V DC POWER
SOURCE, SUCH AS A SOLAR
BATTERY SYSTEM OR CHARGE CONTROLLER.
THE FRIDGE WILL AUTOMATICALLY OPERATE ON 24V DC. THE
USER DOES NOT NEED TO MAKE ANY ADJUSTMENT.
ATTENTION: Polarity is important in wiring this DC appliance. Be
sure that the positive terminal of the battery or charge controller
coincides with the positive wire to the compressor, and the nega-
tive 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.

IN-LINE FUSE
For 24V operation use a 30A fuse. 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.
A 30A fuse is provided with this fridge/freezer.

DC POWER CONNECTION continued
ATTENTION
If a longer connection cable is necessary, the cable cross section
(or gauge) must be equal to or greater than the cable sizes recom-
mended on the following table. Be careful that the input voltage at
the appliance does not drop below the cut-out voltage of the com-
pressor.
LOW VOLTAGE DISCONNECT
The compressor electronics includes a low voltage disconnect
feature. If the input voltage to the appliance falls below 22.8V the
compressor will shut-o. Once the voltage increases above 24.2V
the compressor will resume normal operation.
This feature is designed to protect the system battery from experi-
encing too low a depth of discharge.
