When not in use, the manufacturer recommends that you close the main valve
on the primary side only and keep the gas tubes connected. This way, you do
not have to find the right pressure level on the secondary side the next time. If
you want to move EasyOne Pro/LAB, you must close both valves, and you can
disconnect the gas tubes.

 To close the gas valves
1 On the primary side, close the main valve A.
 The main valve A closes clockwise.
 The pressure that is displayed on the manometer on the primary side B
does not drop, but stays the same because the pressure is not relieved.
This is correct.
