It is dangerous !
Warning: Do not touch the power plug of the refrigerator when your
are wet or your feet are in contact with water. This is dangerous
When the product is used in cars and ships, it must be ensured that
the power supply has fuses and ground protection devices.
Well ventilated: the car fridge is well ventilated and easy to heat
dissipation. There should be some space around the car fridge.

The
places,
The plane of the car fridge must be flat and firm. When
the car fridge is placed on the car, it should be fixed with a pull belt.
The installation of 12/24V DC power supply on board must have
professional electrical operation.
When charging batteries, it is necessary to ensure that car fridge have
been disconnected frompower supply.
To ensure that the voltage of the power supply connected to the product
is correct at any time, the voltage parameters are verified on the
parameter label at the bottom of the product.
Do not use electrical products inside the car fridge.

Avoid moisture: Car fridge should avoid excessive moisture, reduce the
chance of rusting metal parts, water shower, will cause poor insulation,
lead to leakage, malfunction.

There are 3 minutes time delay to protect the compressor,which means after
the car fridge turned on,the compressor will not work at once, it will start to
work after 3 minutes.And at this time,the cabinet temperature in the fridge
> the setting temperature(+3C),and turned on.When the cabinet temperature
in the fridge = the setting temperature,compressor stop working.
To protect the compressor,it will restart to work again after at least 3 minutes.
Power memory function:After restart,the temperature set will be as same same
the one you set before power off.
4.Simple Fault Analysis
The refrigerator does not work
Check if the power supply is connected correctly (whether the plug is loose,
whether the positive and negative poles are connected incorrectly)
Check if the ventilation and ventilation conditions are normal.
Check if the fuse is blown
Check if the power switch on the control panel is turned on.
Abnormal noise in the refrigerator
The car refrigerator is not placed smoothly
Hit the wall or other items
internal parts loose or fall off
Condensation on the surface of the refrigerator
When the ambient air humidity is >75%, the surface of thecabinet may be
slightly condensed. The higher the humidity, the greater the probability of
occurrence, which is normal.
Refrigerator cooling is not good
The food storage is too large, placed crowded, cold air flow isnot smooth
The door is not closed
The door cover sealing strip is damaged or deformed, and the sealing property
is deteriorated;
Poor ventilation in the radiator of the car
Put too much hot food
Improper working mode of the refrigeratorrefrigerator
Sunlight or near heat source
improper temperature setting

Similar to the sound of running water in the refrigerator
This is the flow sound of the refrigerant, which is normal.
There will be a loud sound when the compressor starts up
When the compressor starts, the sound will be slightly larger, and the
sound will decrease after the speed is stable, which is normal.

5.Cleaning And Maintenance
Cleaning method:
Clean the appliance inside and out with a clean damp cloth every two weeks.
If it is dirty, wipe it with a
neutral detergent and then wipe it drywith a damp
cloth. If there is too much water, you can use the drainagepipe at the bottom
of the tank to drain
Maintenance of plastic parts:
To properly protect the seals, clean the plastic parts frequently and try to avoid
heavy impact during use. If oil(Animal or vegetable oil)is attachedplastic parts
for a long time, the plastic will easily deteriorate and crack,and smells bad.
