Note: Always ensure the pump is properly installed and submerged (if applicable) before connecting to power to prevent dry-run damage.

5. Operating Instructions

5.1 Manual Control

The LCD display controller allows for direct adjustment of the pump's flow rate. Use the up/down arrows on the controller to increase or decrease the pump's power output and flow. The display will show the current power level (e.g., P23w) and a bar graph indicating intensity.

5.2 WiFi Control (App)

For advanced control and scheduling, download the Jebao Aqua app from the App Store (iOS) or Google Play Store (Android). Follow the in-app instructions to connect your pump to your smartphone via WiFi.

Download and install the "Jebao Aqua" app.
Open the app and create an account or log in.
Select "Add Device" and follow the prompts to connect your MDP pump. The controller supports Smart AP mode, allowing direct connection without a router for initial setup.
Once connected, you can adjust flow rates, set schedules, and monitor pump status remotely.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Jebao MDP pump.

Disconnect Power: Always unplug the pump from the power outlet before performing 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 chamber using a soft brush and warm water. For stubborn buildup, a mild vinegar solution can be used, followed by thorough rinsing.
Inspect Ceramic Shaft: Check the wear-resistant ceramic shaft for any signs of damage or excessive wear. Replace if necessary.
Clean Inlet/Outlet: Ensure the inlet and outlet ports are free from obstructions.
Reassemble: Carefully reassemble the pump, ensuring all parts are correctly aligned and seals are intact.

Frequency of cleaning depends on water quality and usage, but a monthly check is recommended.

7. Troubleshooting

Problem	Possible Cause	Solution
Pump not running	No power; Dry-run protection activated; Locked rotor protection activated.	Check power connection. Ensure pump is submerged (if applicable). Check for obstructions around the impeller. Reset power.
Reduced flow rate	Clogged impeller or intake; Air in the system; Incorrect flow setting.	Clean impeller and intake. Bleed air from plumbing. Adjust flow rate via controller or app.
Unusual noise/vibration	Debris in impeller; Worn impeller or shaft; Improper installation.	Clean impeller. Inspect impeller and ceramic shaft for damage and replace if necessary. Ensure pump is securely installed and not vibrating against surfaces.
Controller not responding/WiFi issues	Controller malfunction; WiFi signal interference; Incorrect app settings.	Restart controller. Check WiFi signal strength. Re-pair with app. Ensure app is updated.

The pump features IC electronic detection for dry/locked rotor protection, automatically shutting off power if no water is detected or the motor is blocked. If these protections activate, address the underlying issue before restarting the pump.
