Setup Instructions
- Clean Components: Before first use, wash all parts of the fountain (stainless steel bowl, filter tray, silicone mat, food bowl) with mild soap and water. Rinse thoroughly.
- Prepare Filter: Remove the activated carbon filter from its packaging. Rinse the filter under running water for several minutes to remove any loose carbon dust. This is crucial for optimal filtration.

- Fill Water: Place the stainless steel fountain body onto the silicone mat. Fill the fountain with water up to the MAX fill line (approximately 2.5 liters). Do not overfill.
- Position Filter Tray: Carefully place the filter tray with the pump and filter into the stainless steel fountain body. Ensure the pump's power cord exits through the designated groove to prevent pinching.
- Add Spout (Optional): If desired, attach the flower spout to the pump's water outlet for a different water flow style.
- Place Food Bowl: Insert the stainless steel food bowl into the designated slot on the silicone mat.
- Connect Power: Plug the USB cable into a compatible USB power adapter (not included) and then into a wall outlet. The fountain will start operating, and the night light will illuminate.
Operating Instructions
- Power On/Off: The fountain operates continuously when plugged in. To turn it off, simply unplug the power adapter from the wall outlet.
- Water Flow Adjustment: The water flow can be adjusted by changing the configuration of the flower spout.
- Use the flower spout with the yellow cap for a gentle bubbling flow.
- Use the flower spout without the yellow cap for multiple streams.
- Remove the flower spout entirely for a wider, bubbling surface flow.
- Night Light: The integrated blue LED night light automatically turns on when the fountain is powered, providing visibility in low-light conditions.
- Water Level: Always ensure the water level is above the minimum mark to prevent the pump from running dry, which can damage it. Refill as needed.
Maintenance
Regular cleaning and filter replacement are essential to maintain the fountain's performance and your pet's health.
- Daily Checks: Check the water level daily and refill as necessary.
- Weekly Cleaning:
- Unplug the fountain.
- Disassemble all components (stainless steel bowl, filter tray, pump, flower spout, food bowl, silicone mat).
- Wash all parts with mild soap and water. The stainless steel parts are dishwasher safe.
- Rinse thoroughly to remove all soap residue.
- Clean the pump: Open the pump cover and remove the impeller. Clean the impeller and the pump cavity with a small brush to remove any hair or debris. Reassemble the pump.
