4. Setup Instructions
- Prepare Water Source: Place a water reservoir (e.g., a bucket or tank) in a suitable location. Ensure it is filled with water.
- Position the Solar Pump:
- Attach the ground stake to the solar pump unit.
- Insert the stake into the ground near your plants, ensuring the solar panel faces direct sunlight for maximum charging efficiency.
- Alternatively, use the provided screws to mount the pump unit on a wall or fence.

The solar panel charges the internal battery even on cloudy days, providing up to 30 days of standby power.
- Connect the Filter and Main Tube:
- Connect one end of the main tube (Ø4 mm) to the pump's water outlet.
- Attach the filter to the other end of the main tube and place the filter into your water reservoir. Ensure the filter is fully submerged.
- Install the Anti-siphon Valve:
Insert the anti-siphon valve into the main tube at a point higher than the water level in your reservoir. This prevents water from continuously siphoning out of the reservoir.

The anti-siphon valve prevents accidental over-watering and backflow.
- Distribute Tubing and Drippers:
- Lay out the main tube to reach your plants.
- Cut the main tube at desired points and insert T-connectors.
- Connect the branch tube (Ø3 mm) to the T-connectors and run it to individual plants.
- Insert a micro dripper into the end of each branch tube and place it near the base of the plant.
- Use the cross connector for parallel irrigation to ensure uniform distribution to up to 15 pots.

RAINPOINT's cross connector enables parallel irrigation for uniform water distribution to multiple plants.
- Secure Tubing: Use the provided cable ties to secure the tubing and prevent kinks or dislodgement.
- Seal Unused Ends: Use the tube end caps to seal any unused branch tube ends.
