- Power On/Off: After connecting the power, press the power button (
) on the controller to turn the pump on or off. If the pump is not used for an extended period, it is recommended to turn off the power. - Adjusting Pump Power/Flow: Use the "+" and "-" buttons to adjust the pump's power and flow rate. The controller typically offers 5-speed power adjustments.
- Feeding Mode: Press the "
" button once to activate the 15-minute feeding mode (indicator light will be on). Press it again to activate the 60-minute feeding mode. During feeding mode, the pump stops running. After the set time, the pump will automatically resume operation. You can also press the "
" button again to manually resume pump operation before the timer expires. - Memory Function: The controller features a memory function that retains your last settings after a restart or power interruption.
Remote Control (for WiFi-enabled models):
Some JDP pump models offer WiFi connectivity for remote control via a mobile application.

Maintenance
Regular maintenance ensures the longevity and efficient operation of your pump.
- Cleaning the Mesh Cover: The pump is equipped with a removable mesh cover that effectively filters foreign matter and prevents small fish from being inhaled. Periodically remove and clean this cover to maintain optimal water flow and prevent blockages.

Troubleshooting
If you encounter issues with your SUNSUN JDP pump, refer to the following common problems and solutions:
- Pump Not Starting/No Flow:
- Check if the power adapter is securely plugged into the outlet and the pump/controller.
- Ensure the power button on the controller (if applicable) is pressed.
- Verify that the pump is receiving power (e.g., indicator lights on controller).
- For external use, ensure the pump is primed with water.
- Reduced Flow Rate:
- Clean the mesh cover and impeller for any debris or blockages.
- Check for kinks or obstructions in the hosing.
- Ensure the water level is adequate for submersible operation.
- Adjust the pump power setting on the controller to a higher level.
- Excessive Noise/Vibration:
- Check for foreign objects in the impeller.
- Ensure the pump is securely placed and the damping foot pads are intact.
- Verify that the pump is fully submerged if used submersibly.
- Abnormal Warning/Mobile Notification (WiFi models only):
- If your WiFi-enabled pump sends an abnormal warning to your phone, check the pump for visible issues (e.g., blockages, dry running).
- Refer to the mobile application for specific error codes or messages.

User Tips
- Model Selection: When choosing a pump, consider the required 'lift' (height the water needs to be pumped) and 'flow rate' (volume of water per hour) for your specific application. For example, for a 2-meter high weeping wall, a model with a lift greater than 2 meters would be necessary. Refer to the Specifications table to select the appropriate model.
- Power Plug Compatibility: The power plug type may vary by region. Please ensure the provided plug is compatible with your local electrical outlets or acquire a suitable adapter if necessary.
- Regular Cleaning: To maintain optimal performance and prevent issues, regularly clean the pump's mesh cover and impeller. This prevents debris buildup and ensures quiet operation.
- Priming for External Use: Always remember to pour water into the pump to prime it before operating in an external setup to prevent damage from dry running.
- Utilize Smart Features: If you have a WiFi-enabled model, take advantage of the mobile app for convenient remote control, monitoring, and receiving timely alerts about pump status.
