Setup
- Choose Location: Select a suitable location in your pond or water feature where the pump can be fully submerged and the fountain effect is desired.
- Attach Nozzle: Select one of the three provided fountain nozzles according to your preferred water jet pattern. Securely attach it to the top of the riser tube.
- Adjust Riser Tube: Adjust the height of the riser tube to achieve the desired fountain height.
- Position Pump: Place the pump on a stable, flat surface at the bottom of the pond. The four suction cup feet provide optimal stability.
- Connect Power: Route the power cable safely to a grounded electrical outlet protected by an RCD. Ensure the cable is not pinched or damaged.
- Submerge: Ensure the pump is fully submerged in water before connecting to power.

Operating Instructions
- Power On: Once the pump is correctly installed and fully submerged, connect the power plug to the electrical outlet. The pump will start operating immediately.
- Adjust Flow Rate: The pump features an adjustable flow rate. Use the control mechanism (if present, typically a lever or dial on the pump or riser) to fine-tune the water flow and fountain intensity.
- Change Nozzle: To change the fountain effect, disconnect the pump from power, remove the current nozzle, and attach a different one. Reconnect power once the new nozzle is securely in place.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your fountain pump.
- Filter Cleaning: The integrated filter should be cleaned regularly to prevent clogging and maintain efficient water flow. Disconnect power, remove the pump from the water, and clean the filter elements under running water.
- Impeller Cleaning: Periodically inspect the impeller for debris (e.g., leaves, algae) that may impede its rotation. Disconnect power, remove the pump cover, and carefully clean the impeller chamber.
- Winter Storage: During freezing temperatures, remove the pump from the pond, clean it thoroughly, and store it in a frost-free location. Do not allow the pump to freeze with water inside.
- Housing Inspection: Regularly check the stainless steel housing and plastic components for any signs of damage or wear.
