5. Setup
5.1 Initial Cleaning
Before first use, rinse all components (water reservoir, filter tray, pump module) with clean water. Do not use soap or harsh detergents on the pump module.
5.2 Filter Installation
Rinse the new filter element under running water for 2 minutes to remove any loose carbon dust. Place the rinsed filter into the filter tray.

5.3 Filling Water
Fill the water reservoir with clean water up to the 'MAX' line. Do not exceed the 'MAX' line to prevent overflow. Ensure the water level is above the 'MIN' line for proper pump operation.
5.4 Charging the Pump Module
The pump module contains a built-in 4000mAh rechargeable battery. For optimal performance, fully charge the pump module before first use. Connect the charging cable to the pump module and a suitable USB power adapter (not included). The charging indicator light will show the charging status.

5.5 Assembly
Place the filter tray with the installed filter into the water reservoir. Then, position the wireless pump module securely into its designated slot on the filter tray. Ensure it is firmly seated.

6. Operating Modes
The pump module features a power button that also functions as a mode switch. Long press for 2 seconds to power on/off. Short press to cycle through operating modes.

Image: The fountain offers two primary water modes: Timer Mode, which operates for 10 seconds every 10 minutes, and Sensing Mode, which activates for 10 seconds when a pet approaches within 50cm.
6.1 Timer Mode
In Timer Mode, the fountain will dispense water for 10 seconds every 10 minutes. This mode ensures regular water circulation and freshness throughout the day.
6.2 Sensing Mode
In Sensing Mode, the fountain activates when a pet approaches within approximately 50cm (19.68 inches) and dispenses water for 10 seconds. This conserves battery life and water, providing fresh water on demand.

6.3 Continuous Mode
If the fountain is connected to a power source via the charging cable, it will operate in Continuous Mode, providing a constant flow of water.
6.4 Indicator Lights
The pump module has indicator lights for:
- Sensing Mode: Indicates active sensing.
- Low Battery: Alerts when battery needs charging.
- Add Water: Indicates low water level.
- Timer Mode: Indicates active timer operation.
7. Maintenance
Regular cleaning and filter replacement are crucial for maintaining water quality and extending the life of your fountain.
7.1 Fountain Cleaning

7.3 Filter Replacement
Replace the filter element every 2-4 weeks, or more frequently if you have multiple pets or notice reduced water flow. Always rinse new filters before use.
8. Troubleshooting
- No water flow: Check if the water level is above the 'MIN' line. Ensure the pump module is correctly seated. Clean the pump and impeller for any obstructions. Check battery level.
- Pump is noisy: Ensure the water level is sufficient. Clean the pump and impeller as hair or debris can cause noise.
- Indicator lights not working: Ensure the pump module is charged. If charging, check the connection.
- Fountain not responding to pet: In Sensing Mode, ensure there are no obstructions between the pet and the sensor. The detection range is approximately 50cm.
