After engine shutdown, compressed air continues flowing through some compressed air lines for approximately 3 minutes.
For this reason, start working on the compressed air control unit, after this time has elapsed.

Firstly, slacken the connection screw (4) in two turns to release the pressure of the system and then remove it completely.
