❓ Frequently Asked Questions (FAQ) Technical
💡 What does it mean for the membrane to be "Replaceable according to EN"? 13831"?
The EN 13831 standard establishes the design, manufacturing, and testing requirements for expansion vessels. The fact that the membrane is replaceable allows only the part in contact with the water to be replaced when necessary, extending the tank's lifespan and reducing maintenance costs.
💡 How should I adjust the air preload of 1.5 bar?
The preload of 1.5 bar This is the factory default setting. It needs to be adjusted. in situ to a slightly lower value (typically 0.2 bar less) than the pump's starting pressure or the minimum static system pressure. It is crucial to do this with the tank empty of water to ensure proper operation.
💡 The boiler 24 AMR-E Stainless Steel Does it offer different performance than the standard?
The Inox model (shot-blasted stainless steel) of 24 liters It has the same technical specifications for pressure and volume as the standard model. Its advantage lies in a superior resistance to external corrosionmaking it ideal for humid or harsh environments.
