Change “Run Time” set points:
To change the time set points, press the set point “SELECT” button until arrows
point to the “Time at 1” or “Time at 2” set point which can be changed from 1 to
999 minutes by pressing the increase or decrease buttons. If it is desired to have
the CentriVap run continuously without alarming at the end of a time period,
press the increase button until the “Time” display says “ON.” The last entered set
point is stored in memory.
If during a run the “STOP” button is pressed, the timers remember the time at
which stop occurred. If “RUN” is then pressed, the timers continue to count
down from the time at which they were stopped. If running program 1, program 2
or program 3, pressing “PROG 1,” “PROG 2” or “PROG 3” resets the timers to
the original set point time and the CentriVap starts a new run.
To reset the timers to the original set point time when running programs other
than program 1, program 2 or program 3, press the start button and hold it for five
seconds. The display will indicate that the timer is reset.
