Ensure the supply cord is dry and not trapped or damaged. Do not place multiple portable outlets or portable power sources at the rear of the device.
Check that the voltage specification on the type plate corresponds to that of the energy supply.
The appliance is to be used only with the power supply unit provided with the appliance.
Do not use electrical appliances inside the food storage compartments of the appliance, unless they are of the type recommended by the manufacturer.
Once unpacked and before turning on, the appliance must be placed on a level surface for more than 6 hours to let the refrigerant settle.
Make sure that the appliance stays horizontal when it is running. The tilt angle must be less than 5° for long-term running and less than 45° for short-term running.
Keep the ventilation openings in the unit casing and in the built-in structure free of obstacles.
Keep the appliance stable on the ground or in the car. Do not turn the fridge upside down to drain.

CAUTION!

Repairs may be carried out only by qualified personnel. Incorrect repair may cause danger.
The lamp and supply cord must be replaced by the manufacturer or qualified persons.

Battery charging (for reference only):

2

Note: It is suggested to switch off the fridge when charging the battery. (The power supply mainly powers the compressor when the fridge is running.)
When the fridge is connected to a solar panel, please place the fridge in a cool place to dissipate heat.
The charging input power should be higher than the working power of the refrigerator (about 40–45W), or else switch off the refrigerator. Otherwise, the battery will run out.
It is suggested to use a 100W solar panel.
MAX solar inp ut voltage: 50V; MAX solar input current: 10A.
Note: The output of the solar panel is unstable, so it cannot power the refrigerator directly.
When using a solar panel, the battery should be put into the refrigerator.

Discharging time (for reference only): In the low battery-protection mode, the battery can last about 4 hours after being fully charged. When the temperature of the refrigerator is set between 35.6-46.4 F (ambient temperature 77 F), it can last 12 hours after the internal temperature stabilizes. Remove or switch off the battery to prevent self-discharge when not in use.

CARE AND MAINTENANCE

■ Cleaning:

Switch off and unplug the device first to avoid electric shock.
Remove the cover and drain water from the hole at the bottom of the device.
Use a wet cloth to clean the device and a separate cloth to dry it.
Do not immerse the fridge in water, pour or spray water over the fridge, or wash the fridge with a dripping-wet cloth.
Do not use abrasive cleaning agents during cleaning as these can damage the device.

■ Storage:
If the device will not be in use for a long time, please follow these instructions.

Switch off and unplug the device.
Take out all items stored in the device.
Wipe off excess water with a soft rag.
Put the device in a cool and dry place.
Leave the lid slightly open to prevent odors from forming.
Recommended storage environment:
ambient temperature: 77℉, ambient humidity: ≤ 75%.

■ Defrosting:
Humidity can cause frost to form in the interior of the cooling device or on the evaporator.
This reduces the cooling capacity. Defrost the device promptly to avoid this.

Switch off and unplug the device first to avoid electric shock.
Take out all items stored in the device.
Keep the lid open.
Wipe out the water.

Never use hard or pointed tools to remove ice or to loosen items which have frozen in place.
