• Periodically inspect dosing tubes for blockages, kinks, or wear. Replace tubes as needed to prevent leaks or dosing inaccuracies.
• Clean the exterior of the unit with a damp cloth. Avoid using harsh chemicals.
• If using solutions that can precipitate or clog, periodically flush the dosing lines with distilled water.

6. Troubleshooting

6.1 Wi-Fi Connection Issues

• Ensure your router is broadcasting a 2.4GHz signal.
• Temporarily disable 5GHz band on your router during initial setup if you have a combined network.

• Reset the dosing pump's Wi-Fi by pressing the ESC button for 5 seconds until the indicator blinks, then retry pairing.

6.2 Inaccurate Dosing

• Perform a calibration check using a graduated cylinder and adjust settings in the app.
• Inspect dosing tubes for blockages, air bubbles, or wear.
• Ensure dosing solution containers are placed below the output point to prevent siphoning. Consider using check valves if siphoning is suspected.

6.3 Pump Not Dispensing

• Check power connection to the unit.
• Verify the dosing schedule is correctly programmed and enabled in the app.
