Important Safety Instructions
To reduce the risk of fire, electric shock, or injury, always follow basic safety precautions when using this electrical appliance:
- Read all instructions before use.
- Do not expose the converter to rain or moisture.
- Do not operate the converter if it has been damaged in any way.
- Ensure the total wattage of connected appliances does not exceed the converter's continuous power rating (2400W).
- Always connect the converter to a grounded outlet.
- Keep out of reach of children.
- Ensure adequate ventilation around the converter.
- Do not disassemble the unit. Refer servicing to qualified personnel.
- This converter is designed for step-down conversion (220-240V to 100-120V) only. Do not attempt to use it for step-up conversion.
Setup and Installation
1. Unpacking
Carefully remove the converter from its packaging. Inspect the unit for any signs of damage during transit. Retain the packaging for future storage or transport.

Operating Instructions
Follow these steps to safely operate your UMI Voltage Converter:
- Connect to Power: Plug the converter's power cord into a 220-240V wall socket. The display will show the input voltage.
- Connect Appliance: Ensure your appliance is switched OFF. Plug your 100-120V appliance into the appropriate output socket on the converter. The converter features two types of output sockets: one for 110V (for US, Canada, Mexico, Taiwan appliances) and another for 100V (for Japanese appliances).
- Turn On Converter: Press the power switch on the converter to turn it ON. The display will show the output wattage.
- Turn On Appliance: Switch on your appliance.

Power Rating and Usage
The UMI 2400W converter has a continuous rating of 2400W. This means it can safely power appliances up to 2400 watts for extended periods. It also has an intermittent rating of 4600W, which allows for short bursts of higher power (5 minutes on / 15 minutes off duty cycle). Always ensure your appliance's wattage does not exceed the continuous rating for prolonged use.

Maintenance
- Cleaning: Disconnect the converter from the power source before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or abrasive materials.
- Ventilation: Ensure the ventilation openings on the converter are not blocked. Proper airflow is crucial for preventing overheating.
- Storage: When not in use for extended periods, store the converter in a cool, dry place, away from direct sunlight and moisture.
- Inspection: Periodically inspect the power cord and the converter for any signs of damage. If damage is found, discontinue use and contact customer support.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Converter does not power on. | No power from wall outlet, loose connection, or internal fault. | Check wall outlet with another device. Ensure power cord is securely plugged into both the wall and the converter. |
| Appliance not working after connecting to converter. | Appliance is off, appliance wattage exceeds converter capacity, or converter is in overload protection mode. | Ensure appliance is switched on. Verify appliance wattage is within the converter's continuous rating (2400W). If overloaded, the converter will alarm and shut off. Disconnect the appliance, press the power button twice to reset the converter, then reconnect a lower-wattage appliance. |
| Converter display shows "E" or an error message. | Overload condition detected. | This indicates an overload. Disconnect the appliance immediately. Press the power switch button twice to clear the error and restart the converter. Connect an appliance with a wattage below 2400W. |
| Unusual noise or smell from converter. | Internal component issue or severe overload. | Immediately disconnect the converter from the wall outlet and all appliances. Do not attempt to use it again. Contact customer support. |
