6. Operating Instructions
- Submersion: Ensure the pump is completely submerged in clear water before applying power. Operating the pump dry will cause damage.
- Power On: Once submerged, connect the USB cable to a DC 5V power source. The pump will begin to circulate water.
- Flow Rate: The maximum flow rate is 500 L/H (130 GPH). The maximum lift height is 1.8 meters (6 feet). Note that the lift height refers to the maximum vertical distance the water can be pushed after connecting a pipe to the nozzle. Actual flow and lift may vary based on hose diameter, bends, and resistance.
- Monitoring: Periodically check the pump's operation and water level to ensure it remains fully submerged and free from obstructions.
