Kit ACV 90448203 3 anodi hor.28x400 lcA300>500

The ACV 90448203 kit 3 anodes hor.28x400 lcA300>500 is a set of three magnesium anodes intended for use in enamelled hot-water cylinders. Parts of this type protect the cylinder’s internal coating from corrosive attack by sacrificial corrosion; the anode material is consumed over time and must be inspected and replaced at regular service intervals. The reference “hor.28x400” indicates a horizontal design with a diameter of 28 mm and a length of 400 mm, but these dimensions are specific to this kit and not a general rule for all such anodes. The “lcA300>500” denotes the intended cylinder capacity range, though the exact compatibility should always be verified against the appliance data plate. Magnesium anodes are selected by the cylinder’s internal dimensions, the number of anodes required, and the water chemistry. For cylinders of the type that use this kit, the anodes are installed horizontally through threaded openings in the cylinder flange. When replacing anodes, ensure the new ones match the original thread size, length, and diameter to maintain full coverage inside the tank. Over tightening or using an incorrect thread can damage the cylinder boss. Also, if the cylinder has been used with a different water treatment (e.g., softened water), the anode consumption rate may change; inspection intervals should be adjusted accordingly. During servicing, check the residual thickness of the anode core. If it has worn to less than half its original diameter, or if there is significant pitting or partial detachment, replace the complete set. Never mix old and new anodes in the same cylinder, as the electrical potential difference can accelerate wear on the older ones. Proper grounding and electrical continuity between the cylinder and the heating system are also essential for the anode to work effectively.
