4. Operating Instructions
Once assembled and powered on, the FEELNEEDY FN-W04 pet water fountain will continuously circulate and filter water, providing a fresh drinking source for your pets. The multi-layer filtration system ensures that pet hair, impurities, and odors are removed, improving water quality.

Water Level Indicator
The fountain features a gentle light indicator. When the water level is sufficient, the light will be violet. If the water level becomes too low, the light will turn red, indicating that water needs to be refilled. The pump will also stop functioning to prevent damage when the water level is critically low.

Cleaning the Fountain
Regular cleaning of the water fountain and its components (tank, pump, spout) is crucial to prevent mineral buildup and maintain hygiene. Disassemble the fountain, clean all parts with mild soap and water, and rinse thoroughly before reassembling.
6. Troubleshooting
- Water not flowing or weak flow:
- Check the water level. If the indicator light is red, refill the water tank.
- Ensure the pump is properly installed and not clogged with debris or pet hair. Clean the pump if necessary.
- Verify that the power cord is securely connected.
- Loud pump noise:
- Mineral buildup can cause increased pump noise. Disassemble and thoroughly clean the pump.
- Ensure the water level is adequate, as low water can cause the pump to run louder.

- Avoid overfilling the water tank.
