1. Introduction
The OLTEANP 8000VA Step Up/Down Voltage Transformer Converter is designed to safely convert electrical voltage between 110-120V and 220-240V. This device allows you to use appliances from different regions without requiring separate equipment, making it ideal for international travel, relocation, or operating imported electronics. It features automatic voltage recognition, multiple outlet types, and built-in safety protections to ensure reliable operation.
2. Safety Instructions
Please read all safety instructions carefully before operating the converter. Failure to follow these instructions may result in electric shock, fire, or damage to the product or connected appliances.
- Do Not Exceed Rated Capacity: Ensure the total power consumption of all connected appliances does not exceed the converter's 8000W (8000VA) maximum capacity. Overloading can cause damage and fire hazards.
- Ventilation: Place the converter in a well-ventilated area. Do not block ventilation openings. Adequate airflow is essential to prevent overheating.
- Dry Environment: Use the converter only in dry indoor environments. Avoid exposure to moisture, rain, or liquids.
- Grounding: Always connect the converter to a grounded electrical outlet.
- Children and Pets: Keep the converter out of reach of children and pets.
- Unplug When Not in Use: Disconnect the converter from the power source when not in use or before cleaning.
- Fuse Protection: The converter is equipped with a premium fuse protection system. If an overload or over-current occurs, the fuse button will pop up. Reduce the load and press the button to reset. Do not attempt to bypass or modify the fuse.
- Inspection: Regularly inspect the power cord and converter for any signs of damage. Do not operate if damaged.

5. Setup
- Unpack: Carefully remove the converter from its packaging. Retain packaging for future storage or transport.
- Placement: Place the converter on a stable, flat, and dry surface. Ensure there is ample space around the unit for proper ventilation. Do not place it near heat sources or in direct sunlight.
- Connect to Power Source: Plug the converter's power cord into a suitable wall outlet. The converter will automatically detect the input voltage (110-120V or 220-240V).
- Connect Appliances: Plug your appliances into the appropriate outlets on the converter. Use the 100-120V output sockets for appliances requiring 100-120V, and the 220-240V output sockets for appliances requiring 220-240V.

6. Operating Instructions
- Power On: After connecting the converter to the wall outlet and your appliances, switch the ON/OFF button to the 'ON' position. The LCD screen will illuminate.
- Automatic Voltage Recognition: The converter will automatically detect the input voltage and display the corresponding output voltages on the LCD screen (e.g., 120V for US outlets, 220V for universal outlets).
- Monitor LCD Display: The LCD screen displays real-time output voltage. Pay attention to any error codes that may appear.
- Power Off: To turn off the converter, switch the ON/OFF button to the 'OFF' position. Unplug the converter from the wall outlet when not in use.

7. Maintenance
- Cleaning: Ensure the converter is unplugged before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
- Ventilation: Periodically check that the ventilation openings are clear of dust and debris.
- Storage: When not in use for extended periods, store the converter in a cool, dry place, away from direct sunlight and moisture.
8. Troubleshooting
The LCD display provides valuable information for troubleshooting. Refer to the error codes below:
| Error Code | Description | Solution |
|---|---|---|
| Err HI | Input/Output High Voltage Protection | Disconnect from power source. Check the input voltage. If voltage is stable, restart the unit. If issue persists, contact support. |
| Err LO | Input Low Voltage Protection | Disconnect from power source. Check the input voltage. If voltage is stable, restart the unit. If issue persists, contact support. |
| Err 04 | High Temperature Protection | Turn off the converter and unplug it. Allow the unit to cool down in a well-ventilated area for at least 30 minutes. Ensure ventilation openings are not blocked. Restart. |
| Err OL | Over Current Protection / Overload | Immediately unplug some appliances to reduce the load. Press the fuse reset button (if popped out). Restart the unit. Ensure total wattage of connected devices does not exceed 8000W. |
| No Power | Unit does not turn on. | Check if the power cord is securely plugged into a working wall outlet. Ensure the ON/OFF switch is in the 'ON' position. Check the fuse button; if popped out, reset it. |
