Function Description & Operation Method

Using of DC12V/24V
Plug the DC power connector into the inlet of the refrigerator

Insert the DC Plug into the cigarette lighter

Using of AC100-240V,50/60Hz

AC connector plug in AC power line insert AC connector inlet

Plug the power connector on the adapter into the inlet of the refrigerator

Plug the AC power line into the home outlet (AC 100-240V,50/60Hz)

Part Name

1. ON/OFF
   Press for 5 seconds,car fridge is at power on/standby mode； When power on, the LCD screen light is on; When shutting down, the LCD screen light goes out
   Note: When shutting down the car fridge and restart,there are 3 minutes time delay for the compressor start to work.

2. ECO/MAX
   Press to choose the working mode(ECO:Energy saving mode;MAX:Fast cooling mode)

3. Temperature Set
   Press or to set the temperature you want,if you do not press any button,the temperature inside the box will be displayed after 3 seconds of flashing.
   Note: When cabinet temperature in the fridge≥the setting temperature+3C° compressor start to work; When cabinet temperature in the fridge≤the setting temperature+3C° ，compressor stop working;

4. Power Memory Function
   After restart, the temperature set will be the same with the one you set before power off.

5. Battery Protection Function
   There is a built-in battery protection module,which can automatically monitor the car battery voltage. Before the battery power consumption affects the normal start of the car, the car fridge will automatically stop working and the LCD screen display the “E1” code to ensure that the car battery will not be exhausted.

6. Battery Protection Gear Adjustment
   Long press for 6 seconds, the LCD screen flashes F1, then short press for seven times, when the LCD screen flashes F8, then press or to adjust to the desired battery protection gear; Stop pressing, the gear value flashes for 3 seconds, and the refrigerator saves the set gear value. The LCD screen redis plays the temperature in the box. The factory default value of the refrigerator is P2 (medium).

Note: The voltage at above form refers input voltage of the compressor, not the battery output voltage.

Different Error Situation & How To Fix

Error Situation

• 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 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 evenly
  Hit the wall or other items
  internal parts loose or fall off

• Condensation on the surface of the refrigerator

  • When the ambient 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 sealing strip is damaged or deformed, and the sealing
  • property is deteriorated;
  • Poor ventilation in the car
  • Put too much hot food
  • Improper working mode of the 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.

How To Fix

2.    Lower battery protection switch to lower setting

E2| Fan overload cutting out| Clean fan or change the fan
E3| Motor start error (the rotor is blocked or the differential pressure in refrigeration system is too high| Disconnect power for 30 minutes then re- start
E4| Compressor speed error protection.| Reduce load on refrigeration system, increase temperature setting. Change the main controller
E5| Thermal cut-out

(overload or internal temp too high)

| Move refrigerator to a well ventilated

place, allow compressor to cool, then

re-start. Ensure all vents and internals

are clean. Clean with compressed air.

E9| Temperature sensor disconnection| 1.Tighten the temperature sensor line

2. Change the temperature sensor line

Cleaning & 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.
  It is forbidden to wash the refrigerator directly with water in order to avoid the decrease of electrical insulation and the rust of sheet metal.
  The following things will damage the coated surface, plastic parts, such as alkaline detergent, soap, grinding powder, hot water, brushes, toluene water, gasoline, alcohol.

• 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.
  Do not store products inside the refrigerator if the unit is not on.
