Operating Instructions
The Biling Solar Fountain Pump operates automatically when the solar panel receives sufficient direct sunlight. There is no battery storage, so the pump will only function during daylight hours.
- Sunlight Dependency: The pump's performance, including spray height and flow rate, is directly related to the intensity of direct sunlight hitting the solar panel.
- Nozzle Selection: Choose from the four included nozzles to achieve different spray effects. Easily swap nozzles by detaching the current one and attaching another.
- Adjustable Flow: The pump features an adjustable flow control. Rotate the dial on the pump to increase or decrease the water flow and spray height.

Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your solar fountain pump.
- Clean Filters: The pump features a double filtration system to prevent debris from entering. These filters are detachable for easy cleaning. Regularly remove and clean the filters to maintain strong water flow.
- Clean Solar Panel: Periodically wipe the solar panel surface with a soft, damp cloth to remove dust, dirt, or leaves that may obstruct sunlight and reduce efficiency.
- Check Water Level: Ensure the pump is always fully submerged in water. Low water levels can trigger the dry run protection and potentially damage the pump over time.
- Winter Storage: In freezing conditions, remove the pump from the water and store it indoors to prevent damage from ice.

Troubleshooting
If your solar fountain pump is not operating as expected, consider the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not working or weak flow | Insufficient direct sunlight | Relocate the solar panel to an area with maximum direct sunlight. Ensure no shadows are cast on the panel. |
| Pump not working or weak flow | Solar panel is dirty or blocked | Clean the surface of the solar panel to remove any dirt, dust, or debris. |
| Pump not working or weak flow | Water level is too low | Add water to ensure the pump is fully submerged. The dry run protection will activate if water is too low. |
| Pump not working or weak flow | Pump is clogged with debris | Remove the pump from the water and detach the filters. Clean any debris from the filters and the pump impeller. |
| No water spray | Nozzle or tube is blocked | Check the nozzle and any connected tubes for blockages and clear them. |
| Water spray is inconsistent | Partial sunlight or fluctuating light conditions | Ensure consistent direct sunlight. Performance will naturally vary with cloud cover. |
