Operating Instructions

- Water Level: Regularly check the water level through the clear window. Refill when the water level approaches the MIN indicator to prevent the pump from running dry.
- Flow Modes: The fountain provides two distinct water flow options. You can switch between the gentle waterfall and bubbling spring by adjusting the top nozzle component.
- Quiet Operation: The ultra-quiet pump operates at a low noise level (as low as 23dB), ensuring it does not disturb your pets or household.
