Original instructions
Interrupting a Cycle After it Has Begun
At any time during a run, the cycle may be stopped by pressing the “STOP”
button. This shuts off all operating functions. After the rotor stops, the lid may
be opened. If it is necessary to re-start the CentriVap, close the lid and press
“RUN.” The CentriVap resumes operation at the same set point parameters and
the timer continues to count down from the time at which the CentriVap was
stopped.
Gas Ballast
The vacuum pump has a gas ballast that can be used to reduce condensation of
vapors in the pump and exhaust line. This is most likely to occur if the Cold Trap
is not running in conjunction with the evaporation process. The gas ballast is
OPEN if the arrow on the gas ballast cap is pointing “IN” towards the CentriVap.
The gas ballast is CLOSED if the cap is rotated 180°, so that the arrow is pointing
“OUT” of the CentriVap.
Safety Precautions
Special precautions must be observed if the materials used in the CentriVap
Concentrator are known to be hazardous, toxic, radioactive, or contaminated with
pathogenic micro organisms. These actions should include but are not limited to
the following:
• Refer to the World Health Organization Laboratory Biosafety Manual,
paying special attention to information about centrifuges and the handling
of hazardous materials.
• Operate or vent the CentriVap Concentrator inside a suitable fume hood or
ventilation device. Load rotors in a ventilation device.
• Periodically inspect all parts of the CentriVap Concentrator including the
lid, gasket, chamber, plumbing components and rotors.
