Setup
1. Unpacking
Carefully remove all components from the packaging. Inspect the pump and accessories for any signs of damage. If any damage is found, do not proceed with installation and contact customer support.
2. Nozzle Attachment
Select the desired nozzle from the three included options. Attach it firmly to the pump's outlet. Ensure a snug fit to prevent leaks.
3. Placement Options
Image: Multi-function intake design showing non-submersible, bottom suction, and side suction capabilities.
- Submersible Use: Place the pump entirely underwater. The pump is equipped with strong suction cups on its base for secure placement on the bottom or side of your container.
- Non-Submersible Use: The pump can also be used outside of water. Ensure the intake hose is securely connected and submerged in the water source, and the pump is placed on a stable, level surface.

4. Water Level (for Submersible Use)
For submersible applications, ensure the water level is sufficient to completely cover the pump. Operating the pump without adequate water can lead to overheating and activate the auto-power-off function.
5. Power Connection
Once the pump is securely placed and, if applicable, submerged, connect the power cord to a properly grounded electrical outlet with GFCI protection.
Operating
1. Power On/Off
Plug the pump into the electrical outlet to turn it on. Unplug it to turn it off.
2. Adjusting Flow Rate

The pump features an adjustable knob located on the front. Rotate this knob to increase or decrease the water flow rate to achieve your desired effect.
3. Auto-Power-Off Function
This pump is equipped with an auto-power-off feature. If the water level drops too low or the pump runs dry, it will automatically shut off to prevent burnout. The pump will restart once sufficient water is added.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your pump.
1. Cleaning the Filter
The pump includes a foam filter to prevent debris from entering. Periodically remove the filter and rinse it under clean water to remove accumulated dirt and debris. Replace the filter if it is damaged or excessively clogged.
2. Cleaning the Pump
The pump is designed to be detachable for easy cleaning. Disconnect the power, then carefully disassemble the pump components. Use a soft brush and clean water to remove any algae, mineral deposits, or debris from the impeller and housing. Reassemble all parts securely before reconnecting power.
3. Winterization (for Outdoor Use)
If using the pump outdoors in regions with freezing temperatures, remove the pump from the water feature before the first frost. Clean it thoroughly, dry it, and store it in a dry, frost-free location until spring.
