Setup
- Choose Location: Place the pump in the desired location within your fountain, hydroponic system, or aquaponics setup. Ensure it is on a stable surface. The integrated suction cups on the bottom of the pump can be used to secure it to a smooth surface.
- Attach Hose: Select the appropriate hose adapter for your tubing size. Attach one end of your tubing (not included) to the pump's outlet nozzle and the other end to your water feature or system.
- Submerge Pump: Ensure the pump is fully submerged in water before connecting to power. Operating the pump dry will cause damage.
- Connect Power: Plug the pump's power cord into a properly grounded electrical outlet.
