Instructions

Car battery protection voltage reference:

The built-in ECO electronic control module automatically monitors the vehicle battery voltage. Before power consumption affects the standard ignition of the vehicle, the onboard refrigerator will automatically disconnect the power supply to ensure the vehicle battery power remains sufficient for ignition.

Note: When the power supply is connected and the refrigerator is turned on, "disconnecting" or "starting" refers to the compressor disconnecting or starting.

Function introduction

After power-on, the digital display screen illuminates for 1 second and then displays normally. The default setting is the last memory function. The display screen temperature figure remains permanently lit in the middle in standby mode.

1. Open and Close

After the power is turned on, the refrigerator is in standby mode. Press the ON/OFF button to open the refrigerator. Once opened, the display will show the current temperature of the storage room, and the unit will begin running.

Warning: The displayed temperature is measured around the sensor. Temperatures may vary at different points within the storage room.

If the displayed temperature differs from the measured temperature, this is normal. When the refrigerator is running, press the ON/OFF button for 3 seconds to return it to standby mode.

2. Temperature Setting

1. After startup, briefly press the ▲ or ▼ key to enter the temperature setting state. The corresponding box temperature number will flash. Each press changes the temperature by 1°C. The maximum settable temperature is 10°C, and the minimum is -20°C.
2. After startup, press and hold the ▲ or ▼ key to adjust the temperature linearly at 2°C per second.
3. In the temperature setting state, if no action is detected for a period, the set temperature will flash for 3 seconds, then exit and save the current setting. The display will show the actual temperature in the box.
4. The default value for initial startup is 0°C / 32°F.
5. Press "Set" to switch between left/right box temperature settings while in the temperature setting state.

3. Celsius/Fahrenheit Temperature Switch

Press the ▲ and ▼ keys simultaneously to change the brightness and Celsius/Fahrenheit degree when the machine is turned on.

4. Operation Mode Switching

In the power-on state, briefly press the ⚙️ button to enter the cooling (MAX)/energy saving (ECO) setting mode. Then, briefly press the ⚙️ button again to switch between cooling (MAX) and energy saving (ECO) modes. "ECO" is displayed in ECO mode, and "MAX" is displayed in MAX mode. The selected mode flashes for 2 seconds before the setting is saved. MAX running mode cools rapidly. ECO running mode operates longer to save energy.

5. Battery Protection Settings

Battery protection is divided into three levels: L (low level), M (middle level), and H (high level).

Press and hold the ? key to enter the battery protection voltage setting state; the current gear icon will flash. Press and hold the ? key again; the H/M/L cycle display will flash. If no key is pressed for 3 seconds, the setting exits, and the corresponding gear icon remains on.

6. Key Lock Setting

After the machine starts, if no operation is performed for more than 1 minute, the host automatically enters the anti-misoperation locking state, and the locking indicator ? will be on for a long time. Press and hold the ? key for 3 seconds to toggle the anti-misoperation locking status.

7. Temperature zone control setting

After starting the machine, press "Set" and ▲ to close the left box, and press "Set" and ▼ to close the right box. There must be one box working between the left and right boxes.

8. Key operation instructions

When keys are pressed, a buzzer rings once to indicate validity. If no key operation occurs within 5 seconds, the key setting exits, and the display returns to the actual temperature. The onboard refrigerator has a power-off memory function; the working state before power-off is restored upon the next power-on.

Install wheels and handles

To ensure product safety during transportation, the pull rod and wheels are packaged separately. The installation method is shown in the following figures.

Accessories:

• Left pull rod ×1
• Right pull rod ×1
• Handle ×1
• Wheels ×2
• Screwdriver ×1
• M4*12 screw ×16
• ST4*12 screw ×4

1. Install handle

Insert the handle into the left and right rods, align the screw holes, and secure them with screws.

Diagrams show inserting the handle into the rods and aligning screw holes, then fixing with screws (ST4*12).

2. Connect brackets with body of fridge

Definition Of Error Codes On The Display

Failures and Solutions

△E1: Low Input Voltage

Failure 1: Insert the refrigerator power cord into the cigarette lighter before the car starts. Solution 1: Wait a while to connect the car after it starts.

Failure 2: The input voltage of the adapter is too low. Solution 2: Adjust the battery protection level to middle-voltage or low-voltage. If it doesn't work, please replace a new adapter.

△E2: Fan Fault

Please replace a new fan if a fan malfunction is identified.

△E3: Input Voltage Fault Due to Compressor Frequently Start

When the refrigerator is used in a car and E3 appears, please shut down for 5 minutes and restart it.

If it doesn't work, it can be identified as an E1 fault; please solve it according to the solution for E1.

When the refrigerator is connecting with an adapter and E3 appears:

1. Please adjust the battery protection level to the middle level or low level.
2. If it doesn't work, please replace a new adapter.

△E4: Low Rotational Speed of Compressor

Please adjust the input voltage and repower it.

△E5: Overheating of Controller Chip

Please power off for 5 minutes and check if the overheating is caused by poor ventilation around the compressor.

Use Suggestions

1. If equipped with a backup battery, you can maintain any set temperature under any circumstances without worries.
2. When placing ice cream, please adjust the temperature to the lowest setting; it requires prolonged power.
3. Prevent health issues from drinking bottled water in high temperatures.
4. Frozen food, rare seafood, and vehicle-mounted refrigerators allow you to enjoy frozen fresh food during your journey.
5. Healthcare products, insulin, and imported drugs require refrigeration; the precise temperature control of onboard refrigerators ensures health safety during travel.
6. Tea leaves are effectively kept fresh in the car refrigerator, allowing you to enjoy fresh and delicious tea anytime during a self-driving tour.
7. The best storage temperature for red wine is 10°C - 18°C (50 - 64.4°F). The precise temperature control of the car refrigerator can effectively ensure the storage temperature of red wine.
8. The storage time of high-grade fruit in a car at high temperatures in summer will not exceed 2 hours. Even with the air conditioner on, the storage time is shorter. Using a car refrigerator can effectively preserve high-grade fruit.
9. The coating of high-grade sunglasses can fall off under high summer temperatures. The car refrigerator is an ideal place to store them.
10. High-grade cosmetics can easily deteriorate in high temperatures in a car. Carrying cosmetics with you and storing them in the car refrigerator is a better choice.
