3.3.1 Connect to the power supply, the compressor protection program will delay the
compressor from working in the first three minutes, during this three minutes, the indicator is
RED, and the display is on and you can set the temperature, or working mode, or car battery
protection level according to your desire. You can also long press ON/OFF button to turn off
the refrigerator, it will not start working until you long press the ON/OFF button again (and still
you need to wait three minutes for the compressor to kick in).
3.3.2 The compressor starts to work three minutes after connecting to the power supply, and
the refrigerator interior starts to cool down.
3.3.3 Factory default working mode is MAX (fast cooling), indicator in RED color, default
battery protection level is “High”.
3.3.4 Press UP or DOWN button lightly to set your desire temperature. When setting
temperature, the digit number keeps flashing; three seconds without any operation, the digit
number stops flashing and resume to read the real temperature interior.
3.3.5 Press SET button lightly to switch the default MAX mode to ECO mode. Every time you
press SET button lightly you will switch between MAX and ECO mode. MAX mode means
Fast Cooling, and it will consume a lot of energy from battery; ECO mode means energy
saving, it will not consume a lot of energy but it can not reach your desire temperature fast. In
Max mode, the indicator light is RED color, in ECO mode, the indicator light is GREEN light.
3.3.6 Press SET button and UP (or Down) button at the same time, you will switch the

If you find the displaying temperature does not match the
real temperature, you can calibrate the temperature
display within the range. For example if the real
temperature is 2°C but it displays 0°C, you can change
the parameter to be 2°C, then the display will read 2°C
instead of 0°C.

3. 4 Adjust the door opening:
a. Take down the stainless chain by a screwdriver
b. Take down the two hinges
c. Install the two hinges on the other side between the door and the tank.
d. Install the stainless chain on the other size between the door and the tank.
4. Trouble Shooting
The appliance is out of working:
——Check the power supply connection
——Check whether the plug and the socket have a good connection.
——Check whether the fuse has been burned out.
——Check whether the appliance is turned on (press the On/Off button for 3 seconds)
——Whether the compressor is in delay start protection when the appliance is starting
up.
The food inside is frozen:
——The setting temperature is too low.
There is sound of water flow coming from the refrigerator
——It is normal, the sound is caused by the refrigerant circulation.
5. Food storage
Freezer ( - 4 F )
——Meat should be cut and wrapped tightly, and then evenly placed in the freezer.
——After buying frozen food, put it in the freezer as soon as it is still in frozen condition.
——Do not put the fresh food and frozen food together.
——Do not put the fruit and vegetable in the freezer to avoid freeze-drying.
——Do not put the glass container or other container with sealed liquid in freezer. Or
there is a possibility of explosion.
Refrigerator ( 32 F ~ 50 F)
——Eggs,butter,milk and bottled drinkse should be put in refrigerator.
——Fruit and vegetable should be put in the crisper for moisture retaining.
——Hot food should be cooled down before it’s placed in, which could help to save power.
——Food must be packed into freezer bags. Leave space between packaged foods to
keep the circulation of cool air.

6. Defrosting
■ After the refrigerator working for a period, frost could be seen on surfaces in the freezer,
which reduces cooling performanceand increases power consumption. In this case, you
need to defrost it.
■ Unplug the refrigerator and open the doors, take the food in the refrigerator to cool place.
Use defrosting shovel to remove ice and frost (also can just let the door open, then ice and
frost will be thawed by the raising temperature). Then use dishtowel to wipe off the ice
water. After that, place the food back to the refrigerator and plug in.
Note: Do not use sharp metal tools to defrost, you will possibly break the coil by doing
so.
7. Care and cleaning
Unplug the refrigerator before cleaning!
■Use soft cloth dampened with warm water to wipe the inner surfaces and external
appearance of the refrigerator.
■Use neutral detergent to clean the heavy stains, and dry with clean soft cloth.
■For long vacation or absences, remove food and unplug the refrigerator. Clean the
refrigerator and leave the doors open a little. Then place the refrigerator in ventilated
place.
NOTE: Do not sprinkle water on the refrigerator during cleaning because that would
reduce the insulating property of electrical components and erode the metal parts.
■Do not use cleansers containing corrosive and deliquescent material ( such as
scouring powder, bleach, soap powder, alkaline cleansers, benzene, gasoline, acid,
hot water and etc.) to clean the appearance panels, door gaskets and plastic
parts.Following situations are normal
■The flow of refrigerant through the evaporator may create a boiling or gurgling sound.
■In the raining and high humidity weather, moisture may form on the outside of
refrigerator or door gaskets. You can wipe damp surfaces with dry cloth.
■The temperature on the back panel may be high (particularly in summer) due to heat
emission of the condenser.
■The temperature on external surface of the compressor may be high when compressor
is working.
■The compressor may cause a high hum or pulsating sound when it is at starting or
stopping step.
■It's normal to hear metal hit noise from compressor when refrigerator is bumped.
