Setup Instructions
Follow these steps to install the AONBOY F2-Pump into your compatible cat water fountain:
- Unpack: Carefully remove the pump from its packaging.
- Rinse: Rinse the pump and all fountain components thoroughly with clean water before first use.
- Assemble Fountain: Assemble your cat fountain according to its specific instructions, ensuring all filters and components are correctly placed.
- Place Pump: Position the pump at the bottom of the fountain's water reservoir. The suction cups on the pump's base will help secure it.
- Connect Tubing: Attach the fountain's water outlet tubing to the nozzle of the pump. Ensure a snug fit.
- Fill Water: Fill the fountain with water to the recommended maximum level, ensuring the pump is fully submerged. Do not overfill.
- Connect Power: Connect the pump's USB cable to a compatible 5V USB power adapter (not included) and then plug the adapter into a wall outlet.

Operating Instructions
The AONBOY F2-Pump operates continuously once connected to power. No additional controls are typically required for basic operation.
- Continuous Flow: The pump will provide a continuous flow of water, encouraging pets to drink more.
- Water Level: Regularly check the water level in the fountain. Ensure the pump remains fully submerged to prevent dry running, which can damage the pump. Refill as needed.
- LED Light: The integrated LED light will illuminate when the pump is powered, providing visibility and a gentle glow.
Maintenance
Regular cleaning is crucial for extending the life of your pump and maintaining water quality. Clean the pump every 2 weeks.
- Disconnect Power: Always unplug the pump from the power source before cleaning.
- Disassemble: Remove the pump from the fountain. Gently detach the front cover and impeller cover. Remove the impeller (rotor) assembly.
- Clean Components: Use a small brush (e.g., a toothbrush or pipe cleaner) to clean the impeller, impeller well, and the inside of the pump housing. Remove any hair, debris, or mineral deposits.
- Rinse: Rinse all components thoroughly under running water.
- Reassemble: Carefully reassemble the impeller, impeller cover, and front cover. Ensure all parts fit securely.
- Clean Fountain: While the pump is disassembled, clean the entire fountain thoroughly, including the water reservoir and any filters.
- Reinstall: Place the cleaned pump back into the fountain and follow the Setup Instructions to resume operation.
