Operating the CentriVap
CAUTION: To avoid personnel injury; Do not operate the CentriVap if the
lid is scratched or nicked, or shows signs of damage. A damaged lid could fail
under vacuum.
While the CentriVap Concentrator is operating, do not lean on the lid, do not
stand near it longer than necessary and do not place hazardous materials within 12
inches.
1. Press the Cold Trap “ON” switch. The top amber indicator will illuminate.
Additional indicators will illuminate, as the Cold Trap gets colder. A green
indicator will illuminate when the Cold Trap reaches operating temperature.
2. Press the CentriVap “ON” switch.
3. Select a program or set the set point parameters.
4. Preheat the chamber if desired.
5. Turn on Heat Boost if the CentriVap is so equipped and additional heat is
desired.
6. Place samples in vials. Normally the vials should be no more than half full.
Place vials in a rotor.
7. Load the rotor with samples into the chamber.
8. Close the lid. A safety switch prevents the CentriVap from starting when the
lid is open.
9. Press “RUN.” If the display was showing set point parameters, it will change
to show actual parameters. Press “RUN” again. The “S” (STOP) in the
display changes to “R” (RUN). The program on the display alternately
displays “R” or the number of the program that is running. If you intend to
run program 1, 2 or 3, simply press “PROG 1,” “PROG 2” or “PROG 3” to
start the CentriVap. A latch will activate to lock the lid closed, the rotor will
start, the vacuum break valve will close and the vacuum pump will start after
the rotor reaches operating speed.
