4. Setup
Follow these steps to prepare your immersion heater for use:
- Ensure the immersion heater is clean and free of any debris or packaging materials.
- Select a suitable heat-resistant container, such as a glass or ceramic mug, cup, or kettle. Ensure the container is stable and can safely hold the liquid and the heater.
- Fill the container with the desired amount of water or other liquid.
- Carefully immerse the metal heating element into the liquid. Ensure the entire heating coil is fully submerged in the liquid. The liquid level should be above the heating coil but below the electrical connection point where the cord meets the element.

5. Operating Instructions
Once the heater is properly set up, follow these steps to operate it:
- After ensuring the heating element is fully immersed in the liquid, plug the device into a compatible 220V power outlet.
- The element will immediately begin heating the liquid. You may observe small bubbles forming around the coil as the water heats up.
- Monitor the liquid. Once it reaches the desired temperature or begins to boil, immediately unplug the heater from the power outlet.
- Do not remove the heater from the liquid immediately after unplugging. Wait approximately 20 seconds to allow the element to cool down slightly and prevent hot liquid from splashing.
- Carefully remove the heater from the container. Be cautious as the element will still be hot.

6. Maintenance
To ensure the longevity and efficient performance of your immersion heater, regular maintenance is recommended:
- Cleaning: Mineral buildup can occur on the heating element, especially in areas with hard water. To clean, first ensure the device is unplugged and has cooled completely. Gently scrub the heating element with a soft brush (e.g., a toothbrush) and a mild descaling agent or a small amount of toothpaste to remove any residue.
- Rinsing: After cleaning, rinse the heating element thoroughly with water.
- Drying and Storage: Ensure the heater is completely dry before storing it. Store in a cool, dry place, ideally in its original packaging or a protective pouch.

7. Troubleshooting
If you encounter issues with your immersion heater, refer to the following common problems and solutions:
- Heater not working:
- Ensure the device is properly plugged into a functioning 220V power outlet.
- Check for any visible damage to the power cord or the heating element.
- If sparking occurs at the wire connection to the immersion heater, discontinue use immediately and contact customer support. Do not attempt to repair it yourself.
- Slow heating:
- Verify that the power outlet provides 220V. If using a 110V outlet, the heating time will be significantly longer (approximately four times longer for a 600W element).
- Ensure the heating element is fully immersed in the liquid.
- Confirm that the container is not excessively large for the heater's 600W capacity.
- Check for mineral buildup on the element. Refer to the 'Maintenance' section for cleaning instructions.
- Unusual odors or sounds:
- Immediately unplug the device. Allow it to cool and inspect for any visible damage or foreign objects. If the issue persists, discontinue use and contact customer support.
