- T-connector for air hoses
- Screws and Wall Plugs for mounting

All components of the Biling Solar Pond Aerator, including dimensions for the solar panel and pump unit.
Setup Instructions
- Solar Panel Placement: Choose a location for the solar panel that receives direct sunlight for the majority of the day. The panel can be mounted using the provided ground stake or wall-mounted with screws. Ensure the panel is angled to maximize sun exposure.
- Air Pump Connection: Connect the solar panel cable to the air pump unit. The air pump unit contains a 4400mAh battery for nighttime operation.
- Air Hose and Air Stone Installation: Attach the two air hoses to the outlets on the air pump. Connect an air stone to the end of each hose. Place the air stones at the desired depth in your pond or tank. Ensure hoses are not kinked.
- Initial Charge: Allow the solar panel to charge the battery for at least 8 hours in direct sunlight before initial use, especially if operating in battery backup modes.

Operating Modes
The Biling 8W Solar Pond Aerator features three distinct working modes to suit various oxygenation needs and extend battery life:
- Strong Bubble Mode: Provides continuous, strong aeration. Ideal for situations requiring maximum oxygen. Expected working time on a full charge is approximately 24 hours (22 GPH).
- Soft Bubble Mode: Offers gentler, continuous aeration. Suitable for maintaining oxygen levels with reduced power consumption. Expected working time on a full charge is approximately 48 hours (11 GPH).
- 10S ON/OFF Bubble Mode: Operates in a cycle of 10 seconds on, 10 seconds off. This intermittent mode conserves battery power, providing the longest operational duration. Expected working time on a full charge is approximately 72 hours.
To switch between modes, press the mode button on the air pump unit. The indicator lights will change to reflect the selected mode.

Maintenance
Regular maintenance ensures optimal performance and longevity of your solar pond aerator:
- Solar Panel Cleaning: Periodically wipe the surface of the solar panel with a soft, damp cloth to remove dust, dirt, and debris. A clean panel ensures maximum sunlight absorption and charging efficiency.
- Air Stone Inspection: Check the air stones regularly for blockages caused by algae or mineral buildup. Clean them by gently scrubbing with a brush or replacing them if heavily clogged to maintain consistent bubble output.
- Hose Inspection: Ensure the air hoses are free from kinks, cracks, or damage that could restrict airflow. Replace damaged hoses as needed.
- Pump Unit Placement: Keep the air pump unit in a dry, protected location, away from direct water immersion, to prevent damage.

Troubleshooting
If you encounter issues with your Biling Solar Pond Aerator, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No bubbles or weak bubbles | Insufficient sunlight for solar panel | Relocate solar panel to an area with direct, unobstructed sunlight. Clean the solar panel surface. |
| No bubbles or weak bubbles | Air stones are clogged | Clean or replace the air stones. |
| No bubbles or weak bubbles | Air hoses are kinked or blocked | Straighten any kinks in the hoses. Check for internal blockages. |
| No bubbles at night | Battery is not sufficiently charged or depleted | Ensure the solar panel receives adequate sunlight during the day to charge the 4400mAh battery. Select a lower power mode (Soft Bubble or 10S ON/OFF) for extended nighttime operation. |
| Pump unit not functioning | Unit is damaged or defective | If all other troubleshooting steps fail, contact customer service for assistance. |
