CARE AND MAINTENANCE
If storing for a long period of time, leave the lid slightly open to prevent mildew and odor build-up.
Defrosting:
Humidity can form frost and ice in the interior of the unit. This reduces the cooling capacity
and needs to be removed.
1. Transfer contents of the unit to another cooler or freezer.
2. Turn off by pressing and holding the power button. Disconnect the power cord from the
power source.
3. Open the DRAIN PLUG so the water can drain out as the frost/ice melts. Leave the lid
open for better air circulation. Wipe any water remaining inside until dry. Replace plug
before using again.
4. Never use sharp objects to remove ice or loosen food that might have frozen in place.
Cleaning:
• Unplug before cleaning. Use a mild liquid detergent with a moist cloth to wipe off dirt and
spills. Let dry. Do not clean with metal souring pads, abrasives, or solvents.
• Do not immerse cord or unit in water or other liquids
• Allow unit to defrost before storing
Replacing the 12/24V DC Plug Fuse:
1. Disconnect the power cord from the power source.
2. Turn the red cap on the plug counter clockwise to remove it. Remove the middle
assembly screw.
3. Replace the defective fuse with one with the same rating (see the specifications section).
4. Reassemble in the reverse order.

• Ensure all power connections are secure as described above
• Check the temperature set points. Reset if needed.
• Make sure the vents are not blocked or damaged
• If the ambient temperature is above 90ºF cooling will be affected. Make sure the cooler
is out of direct sunlight.
• Frost will affect cooling. If it has built-up, defrost as described above.
• If the above actions do not correct the problem, select the EMERGENCY position on the
OPERATION SWITCH. If that doesn’t fix the problem, contact Aervoe Industries, Inc.

OPERATING INSTRUCTIONS
Before first use, clean the inside with a damp cloth.
Set Up:
1. Make sure all packing materials have been removed.
2. The lid can be hinged from either direction or removed completely. Squeeze and lift up on
either or both latches to open. To close push firmly to ensure the latch seals completely.
Connecting To A Power Supply (12V/24V DC or 120V AC):
• Connect the rubber DC plug on the DC POWER CORD into the DC INPUT of the unit.
• 12V/24V DC Operation (vehicle or portable power center): Before plugging the other end
into a vehicle’s power receptacle, start the engine. If the vehicle battery becomes too low
it will automatically shut down to protect the battery. Plug the DC plug with the red tip
into the DC output of a portable power center or vehicle power receptacle.
• 120V AC Operation: Plug the DC plug with the red tip into the female socket of the DC to
AC converter. Plug the converter into any 120V AC electrical outlet.
• Solar Collector Operation: Because this unit contains a low-wattage compressor,
the Sierra Wave 80-Watt or 120-Watt Solar Collector can be used to power it. If your
model is the #6988 (42-qt.) or #6989 (53-qt.) unit, use the 120-Watt Collector. Read all
instructions provided with the solar collector. The solar charge controller provided with
the Sierra Wave Collector must be used to prevent damage to the cooler or collector.
Plug the DC plug with the red tip into the female socket of the barrel power adapter
provided with the solar collector. Plug that adapter into the LOAD port of the solar charge
controller.
Energy Saving Tips:
• Choose a well ventilated location out of direct sunlight
• Allow warm food to cool before placing inside
• Do not open more than necessary and for longer than needed
• Defrost if a layer of ice forms
• Avoid unnecessary low temperatures

• Do not operate if cord is frayed and wires are exposed
• Use only in a dry environment. Do not submerge in liquid or use in a wet outdoor
environment.
• Do not use or store near open flame or sources of heat
• Do not use in flammable or explosive environments. Never store aerosol containers or
other flammables inside.
• Do not clean with corrosive chemicals. Follow the cleaning instructions provided.
• Cooling performance can be affected when ambient temperatures are below 32ºF or
above 90ºF. Place out of direct sunlight to prevent overheating.
• Defrosting may be required. See instructions provided.
• Do not dispose of the unit in a landfill as it contains refrigerant gas. Contact your local
waste management authority for proper disposal instructions.
FOODS, LIQUIDS, AND MEDICINE
• For safety, keep foods in closed containers
• To prevent spoilage, remove contents prior to storage. Routinely clean the inside of the
unit according to the care and maintenance instructions provided.
• If used to refrigerate medication, it is the sole responsibility of the user to ensure
proper temperature is maintained. Aervoe Industries, Inc. assumes no responsibility for
improperly refrigerated medications.
Using the Fridge/Freezer:
1. Place the OPERATION SWITCH in the NORMAL position.
2. Press and hold the POWER BUTTON for 1-2 seconds. The LED POWER INDICATOR LIGHT
will illuminate (see color information in the Specifications section). Press and hold again to
turn off.
3. The CONTROL PANEL will show the current temperature of the large interior compartment.
The temperature of the small compartment will be higher than the large compartment and is
suitable for refrigerated foods.
4. Temperature can be displayed in either Fahrenheit or Celsius. Press the SET BUTTON 2
times and use the (+) or (-) button to select either Fahrenheit or Celsius as your preferred
display. The display will flash several times and return to the current temperature.
5. To set the temperature between -7ºF and 53ºF (-22ºC and 10ºC), press the SET BUTTON
once and use the (+) or (-) buttons to increase or decrease the temperature. The requested
temperature will flash several times and return to the current temperature.
NOTE: EMERGENCY SWITCH. If a failure occurs, slide the OPERATION SWITCH to the
EMERGENCY position. The unit will operate in full cooling mode to preserve foods until the failure
is resolved. Contact Aervoe Industries, Inc. for service.
Battery Monitor:
Protects your vehicle battery against excessive discharge. If the unit is operated when the vehicle
engine is off, it will automatically switch off and the red LED WARNING INDICATOR will flash
when the battery voltage falls below a set level. The unit will switch back on once the vehicle
battery has been recharged to a safe voltage. If the warning LED fails to stop flashing after the
battery voltage has returned to a normal level, unplug the unit from the power supply to reset.
The Meter may be set for Low, Medium and High sensitivity. When High is selected the battery
monitor will react at a higher voltage tolerance. High is recommended when operating from a
vehicle battery. Low is recommended if operating from a 12V/24V power supply or solar collector.
1. Press the SET BUTTON 3 times.
2. Use the (+) or (-) buttons to select the Battery Monitor Mode. The display will flash several
times and return to the current temperature.
