6. Load the rotor with samples into the chamber.
7. Close the lid. A safety switch prevents the CentriVap from starting when the

lid is open.

8. 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.

9. Set point parameters can be altered at any time during a run by first selecting

the parameter using the set point “SELECT” button and then pressing the
“INCREASE” or “DECREASE” switch.

10. If the time set point is used, at the end of the set time an alarm sounds. All

functions cease.

11. Press “STOP” to terminate operation if the CentriVap has not already stopped

itself.

12. When the evaporation is complete, allow the rotor to stop moving, lift the lid

and remove the samples.

Operational Note

When the CentriVap power switch is turned ON, the CentriVap returns to the
same mode (“RUN” or “STOP”) that it was in when the power switch was turned
OFF. If the CentriVap was in the “RUN” mode when the power switch was
turned OFF, when the power switch is turned ON, the CentriVap attempts to
return to the programmed set points and continue the run.

Cycle Interruption

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.
