1. Choose a Nozzle: Select one of the three provided nozzles based on your desired water effect. Attach it firmly to the pump's outlet.
2. Position the Pump: Place the pump in the desired location within your water feature. Ensure it is fully submerged and resting on a stable surface. The four strong rubber suction cups on the bottom of the pump can be used to secure it to a smooth, clean surface, preventing it from moving or vibrating during operation.
