Maintenance
- Regularly inspect the solar panel for dirt or debris and clean it with a soft, damp cloth to ensure optimal charging efficiency.
- Check the fountain nozzles periodically for blockages and clear them to maintain consistent water flow.
- During winter months or extended periods of non-use, it is recommended to remove the fountain from the pool, clean it thoroughly, and store it in a dry, protected area.
Troubleshooting
Light Not Turning On at Night (Light Sensor Issue)
If the light does not turn on automatically at night, it may be because the light sensor was paused. This happens if the light was turned off using the [OFF] button on the remote.
- Press the [ON] button on the remote control.
- Alternatively, long-press the light's side button to restart it.
- The white indicator light on the unit means the light sensor is active again.
- To test the light sensor, cover the solar panel with an opaque object (e.g., towel, cardboard, or hand) for 1-2 seconds. If the light turns on and the indicator light is white, the sensor is active. If it stays off, press [ON] and test again.
Light Flickering
If the light flickers, it may indicate a pairing issue or low battery.
- Ensure the solar panel is receiving adequate sunlight for charging.
- Hold the [SUN] button on the remote control to re-pair the remote with the fountain unit.

Insufficient Water Spray
- Ensure your pool filter pump meets the minimum requirements. A filter pump of at least 0.2 HP or higher is recommended for optimal performance.
- Check for any blockages in the fountain's nozzles or the connecting pipes.
- Adjust the pressure regulator to increase water flow.
