The manual begins with safety information, warning that the descaling solution contains up to 25 % lactic acid and can cause serious eye damage. It advises wearing protective gloves, goggles and clothing, and provides emergency contact numbers for poison‑center assistance.
The core of the document describes the descaling procedure: pour the solution into the water tank, run two 150 ml water cycles through the steam wand, let the solution sit for 15‑20 minutes, repeat the cycle every three minutes until the tank is empty, then thoroughly rinse the tank and run two litres of fresh water through the machine to clear any residue.
