Product Components
The AISITIN Solar Fountain Pump consists of the following main components:

Setup Instructions
- Choose Location: Place the solar fountain pump in an area that receives direct and unobstructed sunlight. The performance of the pump is directly dependent on sunlight intensity.
- Attach Nozzle: Select your desired nozzle attachment and firmly connect it to the pump's outlet. The pump includes various nozzle options to create different water spray patterns and heights.
- Adjust Bracket (Optional): The integrated bracket can be adjusted to different angles to fit various bird bath sizes. Extend the arms of the bracket to secure the fountain in the center of your bird bath, preventing water spillage. When not in use, the bracket can be tucked away.
- Place in Water: Submerge the pump completely in water. Ensure the water depth is at least 2 inches (5 cm) to allow the pump to operate effectively and prevent damage.
- Initial Operation: Once placed in direct sunlight and fully submerged, the pump will start operating immediately. There is no battery storage, so it will only work when exposed to sufficient sunlight.

Operating Instructions
The AISITIN Solar Fountain Pump is designed for simple, automatic operation under sunlight.
- Sunlight Dependent: The pump operates only when the solar panel receives sufficient direct sunlight. It does not store energy in a battery, so it will stop or reduce performance in shadows, cloudy conditions, or at night.
- Spray Height: The height and strength of the water spray are directly proportional to the intensity of the sunlight hitting the solar panel. Stronger sunlight results in a higher spray.
- Nozzle Customization: You can change the spray pattern by interchanging the provided nozzles. Experiment with different nozzles to achieve your desired aesthetic and to suit the size of your water container.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your solar fountain pump.
- Keep Solar Panel Clean: Dust, dirt, and debris on the solar panel can significantly reduce its efficiency. Wipe the surface of the solar panel regularly with a soft, damp cloth to ensure maximum sunlight absorption.
- Change Water Regularly: To prevent impurities from clogging the pump, change the water in your bird bath or pond frequently. Stagnant water can also lead to algae growth.
- Clean the Pump: Periodically clean the pump to remove any accumulated debris, such as leaves, dirt, or algae, which can block the intake or impeller.
- Carefully remove the pump from the water.
- Disassemble the pump cover and impeller housing.
- Clean the impeller and the pump's interior with a small brush or cotton swab.
- Reassemble the pump, ensuring all parts are securely in place.
