4. Operating Instructions
Once assembled and plugged in, the fountain will begin operating automatically. The water pump is designed for ultra-quiet operation (≤30dB, 1W), ensuring minimal disturbance.
- Water Level Indicator: The translucent water tank features a built-in LED light. When the water level is sufficient, the light will be blue. When the water level is low, the light will turn red, indicating that water needs to be refilled.
- Continuous Flow: The fountain provides a continuous flow of filtered water, which naturally encourages pets to drink more.

LED light prompt indicating water levels: Blue for normal, Red for low.

The ultra-quiet pump ensures a peaceful environment for both pets and owners.
5. Maintenance
Regular cleaning and maintenance are crucial for your pet's health and the longevity of the fountain.
- Weekly Cleaning: We recommend cleaning the entire fountain, including the water tank, filter tray, and pump, every 1-2 weeks. The simple design allows for easy disassembly and cleaning.
- Filter Replacement: The 4-layer filtration system effectively removes hair, food residues, dust, odors, and heavy metals. For optimal filtration, replace the filter (L75) and sponge every 1-2 weeks, or more frequently if you have multiple pets or notice reduced water flow.
- Pump Cleaning: Clean the pump (P75) regularly to prevent mineral buildup and ensure efficient operation.
