Acquire the correct replacement filter element from MAHLE’s website, authorized distributors, or local suppliers. Before starting, ensure the system is shut down and depressurized. Wear appropriate personal protective equipment (PPE). Dispose of the used filter element according to local regulations and safety protocols. Open the filter housing according to the manufacturer’s instructions. Carefully remove the old filter element, noting how it was installed.
