🛠️ Maintenance & Care

🧼 Regular Cleaning

• Keep vacuum tubes free from dust and debris 🌫️
• Ensure collector surface is not obstructed by leaves or dirt 🍂

💧 Water Quality Check

• Use soft water to prevent scaling inside tubes & tank 🚰
• Add a descaling solution annually if hard water is used ⚗️

🔍 Leakage Inspection

• Check tank & pipe connections for leaks or corrosion 🔎

🔄 Vacuum Tube Check

• Look for cracks or damage in the glass tubes 🏺
• Replace any damaged tubes immediately 🛠️

🛡️ Insulation & Frame Check

• Ensure PU foam insulation is intact to prevent heat loss ❄️
• Tighten loose bolts or screws in the mounting frame 🔩

❄️ Winter Care (For Cold Regions)

• Drain the system to prevent freezing in subzero temperatures 🌡️
• Install an anti-freeze mechanism or heating rod if needed 🔥

📅 Annual Professional Servicing

• Schedule a technician visit once a year for efficiency check 🔧
