1. Ifihan
Thank you for choosing the hygger Mini Aquarium Heater 30W. This digital, adjustable temperature heater is designed to maintain a stable and optimal water temperature for small aquariums, including Betta and turtle tanks, ranging from 11 to 30 liters (3-8 gallons). Please read this manual thoroughly before installation and operation to ensure safe and efficient use of the product.
This heater features advanced safety mechanisms, including explosion-proof components, overheat protection, and low water level detection, providing a reliable heating solution for your aquatic environment.
2. Alaye Aabo
- Always ensure the heater is ni kikun submerged in water during operation. Operating the heater out of water will cause it to overheat and trigger the "Er" error code, leading to automatic shutdown.
- Before performing any maintenance, water changes, or cleaning of the aquarium, yọ ẹrọ ti ngbona kuro from the power outlet. Allow the heater to cool down for at least 15 minutes before removing it from the water.

- Ensure the power outlet is equipped with a Ground Fault Circuit Interrupter (GFCI) for added safety.
- The heater's internal components include insulated explosion-proof quartz heating tubes and an ABS outer casing designed not to melt at high temperatures, enhancing safety and durability.
- In case of an error (e.g., "EE" for overheat, "EU" for low temperature, "Er" for out of water), the system will emit a buzzing sound and automatically shut off. Address the issue immediately. While the system cuts power, residual heat may still be present.

- Ibi: Position the heater vertically or horizontally inside the aquarium. Ensure it is fully submerged in water. Use the provided suction cups to secure the heater firmly to the aquarium glass.
- Yiyi Omi: For optimal performance and even heat distribution, it is recommended to install a water pump or filter to maintain good water circulation around the heater. This prevents localized overheating.
- Ibi Alakoso: Place the external digital temperature controller in a dry location, easily accessible for temperature adjustments. Ensure it is not exposed to water splashes.
- Asopọ agbara: Once the heater is securely placed and fully submerged, plug the power cord into a suitable electrical outlet.

6.1 Ṣiṣeto iwọn otutu
- After plugging in the heater, the digital display on the external controller will show the current water temperature.
- Press the "SET" button on the controller. The display will flash, showing the currently set temperature.
- Continue pressing the "SET" button to cycle through the desired temperature range (15°C - 34°C). Each press will increase the set temperature by 1°C.
- Once your desired temperature is displayed, stop pressing the "SET" button. The display will flash a few times and then return to showing the current water temperature, indicating that the new setting has been saved.
- The heater will automatically begin heating if the current water temperature is below the set temperature. A red indicator light on the controller signifies active heating. A blue indicator light signifies that heating has stopped (temperature reached or exceeded set point).

6.2 Error Indicators and Protection
- Over Temperature Protection ("EE"): If the water temperature reaches or exceeds 36°C (96.8°F), the LED display will show "EE", and the heater will emit a buzzing sound before automatically switching off. This protects your aquatic life from excessive heat.
- Low Temperature Protection ("EU"): If the water temperature drops below 12°C (53.6°F), the LED display will show "EU", and the heater will emit a buzzing sound before switching off. This indicates a potential issue with heating or an extremely cold environment.
- Out of Water Protection ("Er"): If the heater is not fully submerged or leaves the water, it will automatically power off and flash an "Er" error code, accompanied by a buzzing sound. The heater will resume normal operation once fully submerged again.

7. Itọju
- Ninu: Regularly inspect the heater for algae or mineral buildup. To clean, unplug the heater and allow it to cool completely (at least 15 minutes) before removing it from the water. Gently wipe the heater surface with a soft cloth or sponge. Do not use abrasive cleaners or harsh chemicals.
- Awọn iyipada omi: Always unplug the heater and allow it to cool before performing water changes in your aquarium. This prevents thermal shock to the heater and potential injury.
- Ayewo: Periodically check the power cord and the heater body for any signs of damage, cracks, or wear. If any damage is observed, discontinue use immediately and replace the unit.
