# 23. Service Room (0), what for?

A room assigned the number **0** is called the **Service Room** — it is designed for placing special machines, such as the **Cooling System**, for example.

Once you register, you can access this room **for free** and place a machine there, if available.\
Just make sure to click on it:

<div data-full-width="false"><figure><img src="/files/cJxhqMNCirzmOqt92Rgw" alt="" width="563"><figcaption></figcaption></figure></div>

After that, you will see either an **empty Service Room** or one **filled with installed machines**.
