2. Safety Precautions
To prevent electric shock, injury, or damage to the heater, please observe the following safety guidelines:
- Always unplug the heater and all other electrical devices in the aquarium before performing maintenance, water changes, or handling the heater.
- Ensure the heater is fully immersed in water before plugging it in. Operating the heater out of water will cause it to overheat and fail.
- Do not operate the heater if the cord or plug is damaged.
- Do not attempt to repair the heater yourself. Refer to qualified service personnel.
- Keep the external controller dry. It is not waterproof.
- Ensure a drip loop is formed with the power cord to prevent water from traveling along the cord and reaching the electrical outlet.
- This heater is designed for indoor use only.

4. Setup and Installation
Follow these steps to properly install your YOFOTHS aquarium heater:
- Unpack: Carefully remove the heater and all components from the packaging. Inspect for any damage.
- Position the Heater: Place the heating rod fully submerged in your aquarium. It can be positioned vertically or horizontally using the provided suction cups. Ensure good water circulation around the heater for even temperature distribution.
- Ensure Full Immersion: The heating rod must be completely submerged in water at all times when powered on. Failure to do so will cause the heater to overheat and malfunction.
- Connect Power: Once the heater is fully submerged, plug the power cord into a standard electrical outlet. Ensure the external controller is kept dry and away from water splashes.

5. Operating Instructions
The YOFOTHS aquarium heater features an external controller for easy temperature adjustment and monitoring.
5.1 Setting the Temperature
- Plug in the heater. The LED display on the external controller will show the current water temperature.
- Press the SET button once. The displayed temperature will begin to flash.
- While the temperature is flashing, press the SET button repeatedly to cycle through the desired temperature settings (range: 64°F to 93°F).
- Stop pressing the button when your desired temperature is displayed. The display will flash a few more times and then return to showing the current water temperature, indicating the setting has been saved.

5.2 Indicator Lights
- Red Light: Indicates the heater is actively heating the water.
- Green Light: Indicates the water temperature has reached the set point and the heater is maintaining a constant temperature.
5.3 Intelligent Memory Function
The heater is equipped with an intelligent memory function. If power is interrupted, the previously set target temperature will be automatically reloaded once power is restored. This prevents the need to reset the temperature after a power outage.
5.4 Overheating Protection
The heater includes an overheating protection feature. If the water temperature exceeds 95°F (35°C), the LED display will show the error code "HI" and the heater will stop operating. Once the water temperature drops below 95°F, the error code will disappear, and the heater will resume normal operation.

6. Maintenance
Regular maintenance ensures the longevity and efficiency of your aquarium heater:
- Cleaning: Periodically clean the heating rod to remove algae or mineral deposits. Always unplug the heater and allow it to cool completely before removing it from the water for cleaning. Use a soft cloth or sponge and warm water. Do not use harsh chemicals or abrasive materials.
- Inspection: Regularly inspect the power cord, plug, and heating rod for any signs of damage, cracks, or wear. If any damage is observed, discontinue use immediately.
- Water Level: Always ensure the water level in your aquarium is above the minimum immersion line of the heater. Evaporation can lower water levels, potentially exposing the heater.
7. Troubleshooting
If you encounter issues with your YOFOTHS aquarium heater, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater not turning on / No display | No power; Loose connection; Heater malfunction | Check power outlet and connections. Ensure the plug is fully inserted. If still unresponsive, contact support. |
| Water temperature too high / "HI" error code | Overheating protection activated; Set temperature too high; Heater too powerful for tank size | The heater will automatically stop. Allow water to cool naturally. Verify set temperature. Ensure heater wattage is appropriate for your tank volume. |
| Water temperature too low / Not heating | Set temperature too low; Heater not fully submerged; Heater malfunction; Tank too large for heater wattage | Increase set temperature. Ensure heater is fully submerged. Check for proper water circulation. Verify heater wattage is sufficient for your tank volume. |
| Inaccurate temperature reading | External thermometer placement; Sensor obstruction | Compare with a reliable external thermometer. Ensure the heater's sensor area is clear of debris. |
