π οΈ Maintenance Guidelines
πΉ 1. Regular Cleaning π§½
β
Clean the vacuum tubes every 3-6 months to remove dust and dirt.
β
Wipe the outer surface of the tank to prevent corrosion.
πΉ 2. Checking for Leaks π§
β
Inspect pipes, valves, and the tank every 3-6 months for leaks.
β
Ensure seals and fittings are intact to avoid pressure drops.
πΉ 3. Descaling & Flushing π°
β
Flush the system with a descaling solution (vinegar or specialized descaler) every 12-18 months.
β
If you have hard water, install a water softener to reduce scaling.
πΉ 4. Pressure Check π§
β
Monitor the pressure relief valve for safe operation.
β
If pressure exceeds 6 bar, install a pressure relief valve.
πΉ 5. Inspect Insulation & Electrical Components β‘
β
Check polyurethane foam insulation for wear.
β
If using an electric backup heater, inspect wiring and thermostat settings annually.
πΉ 6. Protective Measures ποΈ
β
In cold climates, use anti-freeze solutions in indirect systems βοΈ.
β
Secure the frame to withstand strong winds π¬οΈ or storms βοΈ.
