1. تعارف
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. حفاظت جي ڄاڻ
- Always ensure the heater is مڪمل طور تي ٻڏي ويو 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, unplug the heater from the power outlet. Allow the heater to cool down for at least 15 minutes before removing it from the water.
- Do not operate the heater if the power cord or plug is damaged.
- هي اوزار استعمال ڪرڻ جو ارادو نه ڪيو ويو آهي ماڻهن (بشمول ٻارن سميت) گھٽ جسماني، حسي يا ذهني صلاحيتن سان، يا تجربو ۽ ڄاڻ جي کوٽ، جيستائين انهن جي حفاظت لاء ذميوار شخص طرفان اوزار جي استعمال بابت نگراني يا هدايت نه ڏني وئي آهي.
- هيٽر صرف اندروني استعمال لاء ٺهيل آهي.
- 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.

5. سيٽ اپ جون هدايتون
- لڳائڻ: 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.
- پاڻي جي گردش: 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.
- ڪنٽرولر جي جڳھ: Place the external digital temperature controller in a dry location, easily accessible for temperature adjustments. Ensure it is not exposed to water splashes.
- پاور ڪنيڪشن: Once the heater is securely placed and fully submerged, plug the power cord into a suitable electrical outlet.

6.1 درجه حرارت مقرر ڪرڻ
- 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. سار سنڀال
- صفائي: 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.
- پاڻي جي تبديلي: 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.
- چڪاس: 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.
8. مسئلا حل ڪرڻ

|---|---|---|---|
| Heater not heating / Display off | None / Display blank | No power, loose connection, power outage. | Check power plug and outlet. Ensure power is supplied. |
| پاڻي تمام گرم | "EE" (Over Temperature) | Water temperature ≥ 36°C. Heater malfunction or external heat source. | Unplug immediately. Allow water to cool. Check for external heat sources. If "EE" persists after cooling, the heater may be faulty. |
| پاڻي تمام ٿڌو | "EU" (Low Temperature) | Water temperature < 12°C. Heater malfunction or insufficient power for tank size. | Check if heater is plugged in and set correctly. Ensure tank size is within recommended range (11-30L). If "EU" persists, heater may be faulty. |
| Heater stops working / Flashing "Er" | "Er" (Out of Water) | Heater is not fully submerged in water. | Ensure the heater is completely submerged. Check water level in the aquarium. The heater will resume once fully submerged. |
| غير مطابقت واري درجه حرارت | ڪو به | Poor water circulation, heater placed in a dead spot. | Ensure adequate water circulation around the heater (e.g., with a filter or pump). Reposition the heater if necessary. |
