Introduction: Product functions

• This product uses a DC variable frequency compressor and drive module, which creates a mobile refrigeration system that is efficient, energy-saving and reliable.
• It is easy to operate the microcomputer intelligent control system, which has accurate temperature control.
• The system has an innovative intelligent dual temperature zone function, which allows for easy switching between freezing and refrigeration functions to accommodate different storage needs.
• It is compatible with various power inputs and recognize DC12/24V voltage, making it suitable for cars, boats, homes and outdoor use.
• It includes low-voltage detection and low-voltage protection, which effectively prevent car batteries from over-discharging.
• The inner container is made of grade plastic, which is safe, doesn't leak and doesn't release unpleasant odors.
• With built-in LED lighting, it is convenient to use at night.
• It includes a high-definition LED digital display.
• With intelligent touch operation buttons and a keyboard child-lock function, it prevents accidental activation.

Precautions

• When using this refrigerator, ensure it is placed in a well-ventilated area to facilitate heat dissipation. Maintain a gap of more than 100mm between the cooling hole on the compressor side and any other objects – this prevents high temperatures from causing damage or malfunction.
• Do not keep the refrigerator door open for long periods. The temperature difference between the inside and outside of the refrigerator will cause the product to form frost, which tampers with the cooling effect.
• Do not clean the refrigerator under water.
• Do not use this refrigerator near radiators, heaters, ovens, open flames or any other heat source as this will reduce its refrigeration performance.
• Use this refrigerator on a flat surface. Using on uneven ground can reduce its service life and cooling efficiency.

Operation instructions

The control panel display shows:

• TEMP UP button
• DISPLAY
• ON/OFF button
• TEMP DOWN button
• CHILD LOCK button
• SET button

Temperature control range: -20-20℃ (-4-68°F)

Temperature display range: -30-40℃ (-22-104℉)

Standard voltage input range: DC 12V / 24V

Maximum limit: DC 30V

1. Refrigerator Start/Stop:

To connect the DC12/24V power supply correctly, follow these steps:

• If the refrigerator is in standby mode (displaying 'OFF' when the button is touched), hold down the ON/OFF button for three seconds to start the refrigerator.
• After starting, the display will show the current temperature and working mode.
• After a startup delay (one minute by default), the refrigerator enters the working mode and the compressor starts to work.
• To stop the refrigerator, hold down the ON/OFF button for three seconds while the keyboard is unlocked.

2. Refrigerator keyboard locking and unlocking operations:

To lock and unlock the keyboard, follow these steps:

• Hold down the CHILD LOCK and SET buttons for six seconds to switch the locking mode. The child-lock icon in the lower right corner will light up.
• The keyboard will lock automatically if there is no operation for 20 seconds.

Refrigerator temperature adjustment

• Press the TEMP UP or TEMP DOWN buttons to adjust the temperature. The current set value will appear on the screen.
• Each press of the button will change the temperature by one degree.
• If you hold down the button, you can quickly adjust to the required temperature.
• If the set temperature remains the same for five seconds, the set value will automatically save.

Refrigerator temperature mode setting

• Press the M button to switch between 'ECO' and 'MAX'.
• Select 'MAX' to quickly cool down to a lower temperature.
• Select 'ECO' to save energy and maintain a constant temperature in the refrigerator.

Low-voltage protection setting

This product has a low-voltage protection function. When the battery voltage is lower than the set value, it automatically stops the compressor to prevent damaging the battery. This is indicated by ‘E1' being displayed on the screen. If the voltage returns to a normal level for one minute, the refrigerator automatically enters the working state. The factory default range is 'mid-range'. To change it, follow the steps below:

• Unlock the keyboard.
• Hold down the SET button for three seconds until a confirmation tone is heard.
• Lightly press the M button again to display one of the battery protection level icons (L, M or H) flashing on the screen.
• Press the TEMP UP or TEMP DOWN buttons to change the setting to your desired protection level.

For a specific value, refer to the table below:

Note: If your refrigerator triggers the low-voltage protection prematurely, it is possible that the power supply voltage is too low or the low-voltage protection value is set too high. It could also be due to your DC supply wiring being inadequate – it is unable to provide sufficient current. Check the suitability of the power wiring and consider lowering the battery protection value if needed.

To ensure the car starts normally, it is recommended to set the protection level to 'H' when using the refrigerator in a car.

Single and double temperature zone function

This product automatically identifies the temperature zone. By inserting the middle partition, the default configuration is the double temperature zone. The left zone serves as the freezing zone, whilst the right zone serves as the refrigeration zone. In this configuration, the freezing zone temperature is adjustable.

When the middle partition is removed, it becomes a single temperature zone. The temperature is set to the desired value.

Cleaning and maintenance

• Before cleaning, unplug the appliance and wipe the inner and outer surfaces with a damp cleaning cloth. Do not clean this appliance directly with water – this can damage electrical components.
• When not in use for long periods, ensure you clean the inside and outside of the refrigerator and keep it dry.

Error code description

If there is an abnormality in the compressor, module, fan, temperature sensing head or input voltage, an error code will display on the screen and the compressor will stop working. To solve this problem, unplug the power supply and plug it back in. The refrigerator temperature display will return, and after one minute, the compressor will start in refrigeration mode again.

The code description is shown in the table below:

Frequently asked questions

• Why does my refrigerator not work properly?
  1. Ensure the power is on.
  2. Check to see if the voltage is too low.
  3. Ensure all connections from the battery to the refrigerator are secure.
  4. Check the fuse.
  5. Ensure the refrigerator is turned on.
  6. Ensure the temperature is not too high.
• Why is the performance of my refrigerator poor?
  1. There is too much food in the refrigerator.
  2. The food in the refrigerator is too hot.
  3. The door is not closed properly.
  4. The door seal (sealing ring) is damaged.
  5. Ventilation around the refrigerator is not good.
  6. Ambient temperature is too high.
  7. Incorrect temperature setting.
• Why can I hear the sound of water flowing in the refrigerator?

  This is normal. It is caused by the flow of refrigerant.

• Why does my refrigerator make a loud noise when starting?
  1. Ensure the refrigerator is on a flat surface.
  2. Check the surrounding objects for vibration.
  3. When the compressor starts, it may initially produce a slightly louder sound as the motor transitions from static to high speed. However, as the speed stabilises, the sound should decrease. This is a normal occurrence and nothing to be concerned about.
• There are water drops around the shell or door seal

  It is normal for moisture in humid air to condense into water droplets when touching cold surfaces. This is known as condensation and is a natural occurrence.
