Troubleshooting and Error Protection:
The manual provides a troubleshooting guide for common issues like the unit not turning on or low refrigeration performance. It also details an error protection function with specific error codes (ER0, ER1, ER2, ER3, ER4, ER5, ER9) displayed on the LED, indicating compressor malfunctions or temperature sensor failures. Solutions for each error code are provided, such as changing the temperature sensor line, checking the battery, changing the fan, or restarting the unit after a power interruption. If issues persist, users are advised to contact Costway.
Safety Instructions:
- Do not use if cabling is damaged, frayed, or has exposed wiring.
- Do not attempt to operate if the unit is wet.
- Ensure the circuit used in a vehicle is fused (recommended 15 Amp for 12V DC, 7.5 Amp for 24V DC).
- Verify voltage compatibility with the socket and cable.
- Do not place electrical devices inside the refrigerator.
- To avoid suffocation, do not allow children/babies to play in or around the fridge/freezer.
Disposal Guidelines:
The product should not be disposed of as unsorted municipal waste. Separate collection facilities should be used for electrical appliances to prevent hazardous substances from leaking into the environment and food chain. Local government should be contacted for information on available collection systems.
