Operating Instructions
1. Initial Calibration
For accurate dosing, it is recommended to calibrate the pump's flow rate. Access the calibration function within the Kamoer app. Follow the prompts to measure and adjust the actual dispensed volume against the target volume.
2. Setting Dosing Schedules
- In the Kamoer app, navigate to the 'Plan' or 'Schedule' section for your X1 PRO2 V2 pump.
- Create new dosing tasks by specifying the start time, end time, total volume to be dosed, and frequency (e.g., daily, specific days of the week).
- The app allows for multiple dosing events throughout the day, providing flexibility for various nutrient regimens.

3. Manual Dosing
For immediate or one-time dosing, use the 'Manual' control option within the app. You can specify the volume to be dosed and initiate the process instantly.
Maintenance
1. Cleaning the Pump Head
Periodically inspect the peristaltic pump head for any residue or buildup from the dosed solutions. If necessary, disconnect the pump from power and carefully clean the rollers and tubing path with a soft, damp cloth. Avoid using harsh chemicals.
2. Tubing Replacement
The dosing tubing inside the pump head is a wear-and-tear component. If you notice reduced flow, inconsistent dosing, or visible wear on the tubing, it should be replaced. Refer to the Kamoer website or your retailer for compatible replacement tubing and instructions.
Troubleshooting
- Pump not turning on: Ensure the power adapter is securely connected to both the pump and a working power outlet. Check the power indicator light.
- Inaccurate or no dosing:
- Verify that the inlet tubing is submerged in the solution and not blocked.
- Check for air bubbles in the tubing.
- Recalibrate the pump's flow rate via the app.
- Inspect the peristaltic tubing for wear or damage.
- App connection issues (WiFi/Bluetooth):
- Ensure your smartphone is connected to a 2.4GHz Wi-Fi network.
- Restart the Kamoer app.
- Press and hold the Reset button on the pump to re-enter pairing mode.
- Ensure the pump is within range of your Wi-Fi router or smartphone (for Bluetooth).
