(only if the power supply lamp is ON, otherwise, the instrument is switched
off, or there is a defect in the power supply). A ready condition exists when
there is sufficient vacuum in the micro vacuum degasser.
exists when the vacuum degasser is in its startup phase.
exists when the micro vacuum degasser detects an internal defect that does
not allow the vacuum to be kept below the error threshold (180 Torr).
In case of an internal leak it is possible that solvent may enter the vacuum chamber
and solvent may leak into the waste drain.
To prevent any damage, switch off the micro vacuum degasser and remove the
solvent bottles from the solvent cabinet to stop any gravity-caused flow of solvent
into the vacuum chamber.
