Depending on ambient atmospheric pressure (depending on altitude or
weather conditions) and on the vapor pressure of the media inside the
collection bottle, the setting of a high underpressure (e. g., 850 mbar, 8
LEDs flash) may lead to continuous operation of the pump. In this case,
a reduction of the suction power is recommended.
Use the keys to select the bottle size (2 liter glass bottle or
4 liter polypropylene bottle), and with it the activation of the
corresponding level sensor. To operate the key “2l Glass“
or “4l PP“ touch the key > 1 second. The LED of the se-
lected bottle flashes blue.
Use the key to turn off the level sensor alarm and to start or stop
the pump during bottle change.
To operate the key “bottle change“, touch the key below the LED
> 0.5 seconds.
