Setup Instructions
- Clean Before Use: Thoroughly clean all components of the fountain before initial use.
- Place the Fountain: Position the fountain in an easily accessible location for your pet.
- Prepare the Filter: The filter must be fully soaked in water for 5-10 minutes before installation. This prevents water from not diffusing properly and causing overflow.

Maintenance
Regular cleaning and filter replacement are crucial for maintaining water quality and the longevity of your fountain.
- Weekly Cleaning: Clean the entire fountain, including the pump, water tray, and water tank, every week.
- Filter Replacement: Replace the Activated Carbon Filter and Sponge Filter every 2 to 4 weeks, or immediately if you notice a decrease in water flow or water quality.
- Multiple Pets: If you have multiple pets, their saliva can make the water tray and tank sticky. In such cases, clean the inner components and replace the water more frequently. Timely filter replacement is especially important.
- Cleaning Precautions:
- Do not wash plastic parts in a dishwasher.
- Avoid getting soap into the filter, as it may not rinse out completely.
