This document is a user manual for a personal coffee machine. The manual includes safety precautions, part descriptions, preparation steps before use, and instructions for brewing espresso coffee.
The manual begins with safety precautions and installation guidance, including checking the box contents, proper grounding, and ensuring the water pressure does not exceed the specified limit. It also describes the parts of the machine and how to prepare it for first use, such as installing the water softener and connecting water and power.
Subsequent sections cover daily operation – pre‑heating, steam use, espresso brewing, and adjusting pressure – as well as regular cleaning, water‑softener regeneration, and fault diagnosis. Detailed procedures help users maintain optimal performance and resolve common issues. This manual is written in Chinese.
