5.3 Power Connection
- Connect the pump's cable to the smart controller.
- Connect the power adapter to the smart controller.
- Plug the power adapter into a grounded electrical outlet.
5.4 WiFi Setup (General Guidance)
For detailed WiFi setup instructions, refer to the specific guide provided with the smart controller or the manufacturer's website. Generally, this involves:
- Downloading the designated mobile application (e.g., "SUNSUN Home" or similar).

6. Operating Instructions
6.1 Basic Operation
Once powered on, the pump will start operating at its last saved setting due to the memory function. Use the smart controller or the mobile application to adjust settings.
6.2 Adjusting Flow Rate / Speed
The smart controller allows for 99 adjustable speed settings. Use the '+' and '-' buttons on the controller or the slider/buttons within the mobile app to increase or decrease the pump's output. Observe the flow rate in your system and adjust as needed for optimal performance.
6.3 Feed Mode
The pump features a 10-minute pause feed mode. Activate this mode via the smart controller or mobile app. The pump will stop for 10 minutes, allowing you to feed your aquatic inhabitants without food being immediately drawn into filtration. After 10 minutes, the pump will automatically resume its previous operation.

7. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your pump.
- Disconnect Power: Always unplug the pump before any maintenance.
- Clean Impeller: Periodically remove the pump's front cover and impeller assembly. Clean any debris, algae, or calcium buildup from the impeller and its housing using a soft brush and clean water. For stubborn calcium deposits, a mild vinegar solution can be used, followed by thorough rinsing.
- Check Inlet/Outlet: Ensure the inlet screen and outlet nozzles are free from blockages.
- Inspect Cord: Regularly check the power cord for any signs of damage or wear.
- Reassembly: Ensure all parts are correctly reassembled and securely fastened before reconnecting power.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power; impeller jammed; dry running (external use) | Check power connection and GFCI. Disconnect power, clean impeller. For external use, ensure pump is primed with water. |
| Low flow rate | Clogged inlet/outlet; dirty impeller; incorrect speed setting | Clean inlet screen, outlet, and impeller. Increase speed setting via controller/app. |
| Excessive noise | Debris in impeller; pump not stable; air in pump (external use) | Clean impeller. Ensure pump is securely placed. For external use, check for air leaks in tubing and ensure proper priming. |
| WiFi connection issues | Incorrect WiFi password; router too far; app issues | Verify WiFi password. Move router closer or use a repeater. Restart app/controller. Consult app's troubleshooting guide. |
