Step 2: Assemble the Pump

Step 3: Place the Pump in the Fountain Base

Water Flow Modes:
Depending on your specific FOFNON fountain model, there may be different water flow modes (e.g., flower waterfall, fountain mode). Refer to your fountain's manual for details on how to adjust these modes, as the pump itself provides continuous flow.
