Notes For Using

Warning: Do not use your refrigerator if any cabling is damaged, frayed or there is exposed wiring.
Warning: Do not attempt to touch the power plug or continue to operate your refrigerator if it is wet or your hands wet.
When using the refrigerator in the vehicle or boat, please be sure that the electricity has a fuse if using mains power.
Good Ventilation: Your refrigerator requires good ventilation around it, space on the back of the refrigerator at least ≥200mm, side of the refrigerator ≥100mm
Avoid the heat: The refrigerator should be placed in the area where with good kept away from heat and avoid direct sunlight. ventilation,
Stable placement: The location of the refrigerator should be flat and sturdy, when placed it in the car, please use a strap to tighten the cabinet and make sure the refrigerator fixed.
The installation of the DC power source in the boat should be handled by a qualified & professional person.
Please make sure the power should be off when charging with a high-speed battery.
Make sure the voltage connection is right at all times, at the bottom of the products, the approved voltage parameters should be marked on the label.
Don’t place any electrical devices inside the refrigerator.
Avoid Moisture: The refrigerator should avoid the moisture in case of rusting; Do not rinse with water in case of insulation failure and electrical leakage failure.

Part Name

1. ON/OFF
   Press for 5 seconds, car fridge will enter the stand by mode.
   Note: After shutting down the car fridge and restarting, there are 3 minutes delay for the compressor to start to work.

2. Temperature Set
   Press or to set temperature that you want. After operation the light will flash for 5 seconds and display the temperature inside the fridge.
   Note: The cabinet temperature in the fridge > the setting temperature(+3℃), and turned on. When the cabinet temperature in the fridge = the setting temperature, compressor stops working.

3. Parameter Functions
   ℃: Celsius degree ℉: Fahrenheit degree
   ECO: Energy saving mode MAX: Fast cooling mode
   : low/med/high battery protection
   Press and display℃, repeat press the button, display ℃,℉, MAX ECO` in turn. When the corresponding parameter flashes, stop pressing to confirm  the parameter setting.

4. Battery Protection Function
   There is a built-in battery protection module,which can automatically monitor consumption affects the car battery voltage. Before the battery power 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.

Note: The voltage level is testing the voltage value of input terminal of the compressor, not the output terminal of the car battery.

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

Different Error Situation & How To Fix

1. 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 will be, 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.

2. How To Fix****
   Error Code| Problems| Solution Method
   ---|---|---
   Er0| Temperature sensor cutting out| Change the temperature sensor line
   Erl| Battery protection cutting out| 1.Change/charge the battery
   2.Lower battery protection switch to lower setting
   Erg| Fan overload cutting out| Clean fan or change the fan
   Er3| 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
   Er4| Compressor speed error protection.| Reduce load on refrigeration system, increase temperature setting. Change the main controller
   Er5| 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.
   Er9| 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.
