The unit has a touch panel so the keys need only be touched gently.
Do not press the keys!
The keys “+“ and “-“ have to be touched > 0.25 seconds to be actuated.
The other keys have to be touched > 0.5 seconds.
Touch the keys with LED below the LED.
A successful action is conrmed by a blip and the ashing of LEDs.
Use the keys to set suction power of the system.
The suction power can be set as underpressure (relative to atmo-
spheric pressure) linearly in a range of 150 mbar (1 LED ashes)
to 850 mbar (8 LEDs ash).

A ashing LED indicates that the actual avail-
able suction power differs from the preset suc-
tion power.
Attention: If the collection bottle is under
vacuum and the vacuum demand is reduced,
the existing underpressure inside the bottle
remains until the vacuum is reduced (pres-
sure rises) by further aspiration or venting
with the VHC
pro
.
Venting the BVC: Press the lever of the VHC
pro
or set the VHC
pro
to continuos aspiration.
