- Plug the other end into a compatible USB power adapter (not included) or a USB port.
- The indicator light will show charging status (e.g., red for charging, green for fully charged).
- A full charge may take several hours.
2. Assembly
- Rinse Components: Thoroughly rinse the water tank, stainless steel tray, and filter housing with clean water. Do not use soap on the filter.
- Install Filter: Place the filter sponge into its designated slot, then insert the 4-layer filter element into the filter housing. Ensure it is seated correctly.

Operating Instructions
1. Filling the Water Tank
- Remove the stainless steel tray.
- Fill the water tank with clean tap water up to the MAX fill line. Do not overfill.
- Replace the stainless steel tray securely.
2. Smart Water Modes
The fountain offers three operating modes. Press the mode button on the main unit to cycle through them.
- Sensor Mode: The fountain activates for 12 seconds when a pet is detected within 4-6 feet by the motion sensor. This mode conserves battery life and provides fresh water on demand.
- Timer Mode: The fountain activates for 12 seconds every 15 minutes. This mode balances water freshness with battery conservation, offering up to 60-80 days of operation on a full charge.
- Continuous Mode: The fountain provides a continuous flow of water 24/7. This mode requires the fountain to be plugged into a power source via the USB cable. It is ideal for pets who prefer constant running water.
Note: Battery life estimates are based on typical usage in Timer Mode. Actual battery life may vary based on usage frequency and environmental factors.
3. Motion Sensor Functionality
In Sensor Mode, the integrated motion sensor detects your pet's presence. Ensure the sensor window is clear of obstructions for optimal performance. The detection range is approximately 4-6 feet.
Maintenance
Regular cleaning and filter replacement are crucial for maintaining water quality and extending the life of your fountain.
1. Cleaning the Fountain
- Frequency: Clean the fountain at least once a week, or more frequently if multiple pets use it or if the water appears dirty.
- Disassembly: Unplug the fountain (if applicable) and disassemble all components: stainless steel tray, water tank, filter housing, filter element, and main unit.
- Washing: Wash the stainless steel tray, water tank, and filter housing with mild soap and water. Rinse thoroughly to remove all soap residue. Do not use abrasive cleaners.
- Main Unit: Wipe the exterior of the main unit (containing the pump and battery) with a damp cloth. Do not immerse the main unit in water.
- Reassembly: Reassemble all components once they are clean and dry.
2. Filter Replacement
The 4-layer filtration system includes activated carbon, ion-exchange resin, and non-woven fabric to purify water. Replace the filter element regularly.
- Frequency: Replace the filter element every 2-4 weeks, depending on the number of pets and water quality.
- Procedure:
- Remove the stainless steel tray and filter housing.
- Discard the old filter element.
- Rinse the new filter element under running water for several minutes to remove any loose carbon dust.
- Place the rinsed new filter element into the filter housing.
- Reassemble the fountain.
