• Observe the display of the manometer: The overpressure must not drop below 25 Pa (recommendation:
>40 Pa).
• Connect the USB stick.
• If the USB stick remains on the unit for a longer period of time, the pressure can be set to an overpres-
sure of at least 25 Pa (recommendation: >40 Pa) on the pressure regulator.
• Close the USB cover on the controller housing (triangle instrument box)
• Now the pressure regulator can be turned back (counter-clockwise rotation) until the clamping ring
touches the upper stop. (Only tighten to the stop by hand)
