Once plumbing is complete, slowly fill the system with water, ensuring all air is purged from the pipes and tank. Check for any leaks during this process.

5. Mode d'emploi

The Racold Alpha Pro Solar Water Heater operates automatically once installed and filled. Sunlight heats the water within the vacuum tubes, which then rises into the insulated storage tank.

• Chauffage initial : Allow sufficient time for the system to heat water after installation or prolonged periods of non-use. This may take several hours depending on sunlight intensity.
• Consommation d'eau chaude : Use hot water as needed. The system will continuously replenish the hot water supply as long as there is adequate sunlight.
• Auxiliary Heating (if applicable): If your model includes an electric backup heater for cloudy days or high demand, refer to its specific operating instructions.

6. Entretien

Regular maintenance ensures optimal performance and longevity of your solar water heater.

• Vacuum Tube Cleaning: Periodically inspect and clean the vacuum tubes to remove dust, dirt, or debris that may reduce solar absorption. Use a soft cloth and mild detergent if necessary.
• Inspection des fuites : Regularly check all plumbing connections and the tank for any signs of leaks. Address any leaks promptly to prevent water wastage and damage.
• Soupape de limitation de pression: Annually test the pressure relief valve by lifting the lever briefly to ensure it operates freely. Follow manufacturer guidelines for this procedure.
• Régions où l'eau est dure : In areas with very hard water, consider periodic descaling of the tank and tubes by a professional to prevent mineral buildup, which can reduce efficiency.
• Vérification structurelle : Inspect the support structure and mounting for any signs of corrosion or loosening, especially after severe weather.
