Operating Instructions
The Moongiantgo Automatic Watering System allows for easy scheduling of watering times and intervals. The dual pump system enables two independent watering schedules (A and B) for different plant needs.
Setting Watering Schedules
Use the buttons on the main unit to set your desired watering parameters:
- ON/OFF Button: Press to turn the system on or off.
- SET Button: Press to enter setting mode. Use this to cycle through watering duration and interval settings for both Pump A and Pump B.
- '+' and '-' Buttons: Use these buttons to adjust the values (seconds, minutes, hours, days) for watering duration and interval.
- MA Button: Manual watering. Press to initiate immediate watering.
- MB Button: Manual watering. Press to initiate immediate watering.
Watering Duration: Can be set from 1 second to 59 minutes (for seconds) or 1 to 99 minutes (for minutes). This determines how long the pump will run during each watering cycle.
Watering Interval: Can be set from 1 hour to 23 hours (for hours) or 1 to 9 days (for days). This determines the frequency of watering cycles.
The dual pump system allows you to set two distinct schedules. For example, Pump A can water delicate plants for a short duration every day, while Pump B can water succulents for a longer duration every few days.

Maintenance
Regular maintenance ensures the longevity and efficient operation of your watering system.
- Clean Filters: Periodically check and clean the water filters to prevent blockages and ensure consistent water flow.
- Inspect Tubes and Nozzles: Regularly inspect the tubes and drip nozzles for any blockages, kinks, or damage. Clean or replace as needed.
- Water Source: Ensure the water reservoir is clean and free of debris to prevent contamination of the system.
- Battery Check: If using batteries, check their charge regularly and replace them when low to avoid interruption of watering schedules.
- Storage: If storing the system for an extended period, drain all water, clean components, and store in a dry, cool place.
Troubleshooting
If you encounter issues with your watering system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No water flow | Pump not running, clogged filter, kinked tube, empty water reservoir. | Check power supply (USB/batteries). Clean filter. Straighten tubes. Refill water reservoir. |
| Inconsistent water flow | Partially clogged filter or nozzle, low water level, air in tubes. | Clean filters and nozzles. Ensure sufficient water in reservoir. Prime the system by running manual watering to remove air. |
| System not turning on | No power, dead batteries, loose USB connection. | Check USB connection. Replace batteries. Ensure ON/OFF button is pressed. |
| Watering schedule not activating | Incorrect settings, system turned off. | Verify watering duration and interval settings. Ensure the system is turned ON. |
| Water pressure is weak | Pump limitation, too many drip nozzles, main unit placed too high above water source. | The pump has a specific pressure rating. For optimal performance, ensure the main unit is not significantly higher than the water source. Consider reducing the number of active drip nozzles if flow is too low for all. |
