Setup Instructions
Follow these steps for proper installation of your drip irrigation system:
- Prepare the Tubing: Before installation, it is recommended to soak the water pipe in hot water for a few minutes. This will soften the tubing, making it more flexible and easier to cut and connect.
- Position the Solar Panel: Choose a location for the solar panel that receives maximum direct sunlight throughout the day. Use the provided ground stake to secure it, or mount it to a suitable surface using the included hardware.
- Place the Controller: Position the controller unit near your water source (e.g., a bucket or reservoir). Ensure it is in a stable location and protected from extreme weather if possible.
- Connect the Water Source: Attach the filter to the intake hose and place it into your water reservoir. Connect the intake hose to the controller.
- Install the Anti-Siphon Device: Connect the anti-siphon device to the outlet of the controller. This prevents water from flowing back into your reservoir.
- Lay Out the Main Tubing: Connect the 15-meter water hose to the anti-siphon device. Route the main tubing to reach all the plants you intend to water.
- Branch to Plants: Cut the main tubing where you need to branch off to individual plants. Use the provided "T" connectors to create branches.
- Insert Drippers: At each plant, attach a dripper to the end of the branch tubing. Ensure the dripper is positioned near the base of the plant, allowing water to reach the root zone directly.
- Secure Tubing: Use the provided ties or other securing methods to keep the tubing in place and prevent kinks.

Programming the Timer:
- Power On: Press the "ON/OFF" button to activate the controller. The digital display will light up.
- Set Watering Duration: Press the "SET" button to enter the watering duration setting mode. Use the "+" and "-" buttons to adjust the watering time from 1 to 90 seconds. This determines how long the pump runs during each watering cycle.
- Set Watering Interval: Press the "SET" button again to enter the watering interval setting mode. Use the "+" and "-" buttons to adjust the interval from 1 to 72 hours. This determines how often the watering cycle repeats.
- Confirm Settings: After setting both duration and interval, press "SET" one more time to save your settings and exit programming mode. The system will now operate according to your programmed schedule.

Smart Solar & Battery Hybrid Power:
The system intelligently switches between solar power and the internal 2200mAh battery. During daylight hours with sufficient sun, the solar panel powers the system and charges the battery. At night or on cloudy days, the system automatically draws power from the charged battery, ensuring uninterrupted watering.
Water-Saving Precision Drippers:
The drippers deliver water directly to the plant's root zone, minimizing evaporation and runoff. This targeted delivery system (400-500ml/min flow rate) can save up to 70% water compared to traditional watering methods, promoting deeper root growth and healthier plants.

Maintenance
Regular maintenance ensures optimal performance and longevity of your irrigation system.
- Clean the Filter: Periodically check and clean the water filter to prevent blockages and ensure consistent water flow. Rinse it under running water to remove debris.
- Inspect Tubing and Drippers: Regularly inspect all tubing for kinks, cracks, or damage. Check drippers for clogs; if a dripper is blocked, gently clean it or replace it if necessary.
- Solar Panel Cleaning: Keep the solar panel clean from dust, dirt, and debris to ensure efficient charging. Wipe it gently with a soft, damp cloth.
- Winterization (if applicable): In regions with freezing temperatures, disconnect and drain the system before winter to prevent damage from freezing water. Store components in a dry, protected area.
