VACUSAFE – Operating instructions V12

ARNING
When working with dangerous substances, you must comply with the
material safety data sheet (MSDS) and the additionally applicable
regulations of trade associations, health authorities, supervisory offices, etc.
In addition, when working with hazardous volatile substances or
biohazardous agents, either place the VACUSAFE inside a biosafety cabinet
or connect the instrument's air outlet (16) to a safety ventilation by means of
a tube and of a connector (Part No. 158427).
4.2 Use of the level sensor
When the VACUSAFE bottle is full, the level sensor prevents foam or liquid from
overflowing and accidentally soaking filter and instrument. As soon as foam or liquid is
detected, the pump switches off (models 158300, 158 310) to avoid overfilling of the
bottle. Additionally, an audible alarm is activated and the switch indicator lamp starts
blinking.
It is possible to deactivate the level sensor by simply disconnecting the sensor cable
(confirmed by a double beep).
Instrument, sensor cable and bottle lid constitute an assembly and they must be calibrated
to match one another (see "3.3.4 Connection and calibration of the level sensor" on
page 8). If you have several lids, sensor cables and instruments and swap them, you have
to recalibrate the newly formed assemblies. Depending on the degree of soiling of the
sensor pins inside the lid, it may be necessary to clean them and to calibrate the level
sensor periodically.
