5. Setup
Follow these steps for proper installation of your submersible pump:
- Placement: Ensure the pump is placed on a stable, level surface within the water body (aquarium, pond, or waterfall basin). The pump must be fully submerged during operation to prevent overheating and damage.
- Fountain Attachment: Connect the desired fountain nozzle attachment to the pump's outlet. Ensure a secure fit to prevent leaks and ensure proper water flow.
- LED Lighting (Optional): If using the LED lighting ring, position it around the fountain attachment as desired.
- Power Cord Routing: Route the power cord safely, ensuring it is not kinked or pinched. The electrical socket must be positioned at a higher level than the pump to prevent water from flowing back into the socket.
- Final Check: Before plugging in, double-check that all connections are secure and the pump is fully submerged.

Operating your SOBO LED-3800FP pump is straightforward:
- Power On: Once the pump is correctly installed and fully submerged, plug the power cord into a suitable electrical outlet. The pump will begin operating, creating a fountain effect, and the LED lights will illuminate.

- Power Off: To turn off the pump, simply unplug it from the electrical outlet.
