  • 0.5 min / 1 min / 2 min / 4 min / 8 min

• Built-in water level sensor stops the pump when water is low

• Automatic battery charging (Ni-MH 7.2V)

3. Main Components

• Control unit (pump + electronics)

• Solar panel with ground spike

• Water level detector

• Filter

• Siphon breaker

• Main supply hose 7m in length (8 mm) Maximum suggested length

• Distribution hose 48m in length for take off lines (4 mm )Maximum suggested length

• Tee connectors, end caps, earth rods

• 50 adjustable drippers (2 L/h max)

4. Installation Overview

1. Place control unit:

   • Vertical is recommended

   • Above max water level but within 2 m of reservoir bottom
     

2. Install solar panel:

   
   

   • Point toward midday sun

   • Avoid artificial light sources

    

3. Set up water intake:

   • Place filter + water level detector at reservoir bottom

4. Connect siphon breaker:

   • Between control unit and main water line

5. Lay water lines:

   • Main supply line (8 mm)

   • Distribution lines (4 mm)

6. Install drippers:

   • Near plants using ground stake

⚠️ Important: At least 20 drippers must be connected to avoid over-pressure.

5. Operation

1. Turn SYSTEM ON/OFF switch ON

2. Check SYSTEM indicator:

   • Green = ready

   • Yellow = charging

   • Red = battery empty

3. Use TEST MODE to manually test water flow

4. Select watering time using MODE SELECT.

5. Adjust each dripper’s flow as needed

6. Watering Performance (Max)

• Per dripper: up to 0.67 L/day

• All drippers combined: up to 21.3 L/day

• Water amount depends on:

  • Number of drippers

  • Selected watering time

  • Dripper flow settings

7. Maintenance & Troubleshooting

• Red flashing ALARM → refill water reservoir

• Clean:

  • Filter

  • Water level sensor

  • Drippers (if blocked)

• If watering time becomes shorter → replace battery

• If battery doesn’t charge → check solar panel position and wiring

8. Safety & Cautions

• Do not modify the system (voids warranty)

• Pump must operate in water only

• Avoid dirty water with particles

• Keep system frost-free in winter

•  Use hot water only to heat water line if requited)
