Setup Guide
- Unpack and Inspect: Carefully remove the pump from its packaging. Inspect all components for any signs of damage. Ensure all parts, including the pump body, impeller, and power cord, are intact.
- Attach Tubing: Connect appropriate tubing (not included) to the pump's outlet nozzle. Ensure a secure fit to prevent leaks.
- Placement: Place the pump securely at the bottom of your sump or aquarium. Ensure it is stable and will not shift during operation. The pump must be fully submerged in water.
- Electrical Connection: Route the power cord safely, avoiding kinks or sharp bends. Plug the pump into a grounded electrical outlet. Ensure a drip loop is formed to prevent water from traveling along the cord to the outlet.
- Initial Test: Once submerged and connected, power on the pump to ensure proper water flow. Check for any unusual noises or vibrations.
Operating Instructions

- Power Off: To stop the pump, simply unplug it from the power outlet. Always unplug before handling the pump or performing any maintenance.
- Water Level: Always ensure the water level in your aquarium or sump is sufficient to keep the pump fully submerged. Running the pump dry will cause damage and void the warranty.
