4. Setup and Installation

The installation process involves assembling the base, mounting the vacuum tubes, and connecting the water lines. While the product is described as 'Indoor Installation' style, solar water heaters are typically installed outdoors to maximize sun exposure. Please consult a professional for proper outdoor installation.

• Site Selection: Choose a location with maximum sun exposure throughout the day. The preferred orientation for the solar collector is South.
• Support Structure Assembly: Assemble the stainless steel support frame according to the provided diagrams (not included in this manual, refer to packaging).
• Collector Placement: Mount the solar collector on the support structure. The optimal inclination angle for the tubes is 22.5 degrees to maximize solar absorption.
• Vacuum Tube Installation: Carefully insert the borosilicate vacuum tubes into the collector manifold. Ensure the silicone seals are properly seated between the vacuum tubes and the tank to prevent leaks.
• Water Connections: Connect the cold water inlet and hot water outlet pipes to the thermotank. Ensure all connections are secure and leak-free.
• Filling the System: Slowly fill the system with water, allowing air to escape. Check for any leaks during the filling process.

5. Operating Instructions

Once installed and filled, the solar water heater operates automatically by absorbing solar radiation to heat the water stored in the thermotank. The system uses water as the working fluid.

• Initial Heating: Allow several hours of direct sunlight for the water to reach its operating temperature. The typical operating temperature can reach up to 80°C.
• Water Usage: The 24-tube model has a storage capacity of 280 liters, suitable for 9-11 people. Use hot water as needed. The system will replenish and reheat automatically with sufficient sunlight.
• Monitoring: Periodically check the water temperature if a thermometer is installed.

6. Maintenance

Regular maintenance ensures the longevity and efficiency of your solar water heater. The expected lifespan of the unit is 25 years.

• Vacuum Tube Cleaning: Periodically clean the exterior of the vacuum tubes to remove dust, dirt, or debris that may reduce efficiency. Use a soft cloth and water.
• Leak Inspection: Regularly inspect all pipe connections and seals for any signs of leaks. Address any leaks promptly.
• Magnesium Anode Rod: The system includes a magnesium anode rod. This rod helps prevent corrosion inside the thermotank. It should be inspected and replaced periodically, typically every 1-3 years, depending on water quality. Consult a professional for anode rod replacement.
• Drainage: In areas prone to freezing temperatures, ensure the system is properly drained or protected with an anti-freeze solution if it's not designed for freeze protection.

7. Troubleshooting

This section provides solutions to common issues. For problems not listed here, please contact customer support.

• Insufficient Hot Water:
  • Check for sufficient sunlight exposure.
  • Ensure vacuum tubes are clean and free of obstructions.
  • Verify proper water level in the tank.
  • Check for leaks in the system.
• Water Leaks:
  • Inspect all pipe connections and tighten if necessary.
  • Check the silicone seals around the vacuum tubes. Replace if damaged.
• No Water Flow:
  • Ensure the cold water supply valve is open.
  • Check for blockages in the piping.
