DO NOT switch CAM OFF when one or more bars are showing
because this action stops the purging of any contaminant
remaining; this would extend the warm-up time on future
The CAM normally clears down to one or zero bars within two
minutes. If CAM is contaminated, it may take at least an
hour to clear down to zero bars.
If display (6) shows zero bars, press G H Pushbutton Switch to change
modes of operation. Observe display again. If display shows zero
bars, CAM is ready for shutdown procedure. In conditions below 401F
(4C), allow CAM to run an additional 5 minutes after the display has
cleared to zero bars. If one or more bars show, let CAM run until
display shows zero bars (Figure 4-35).
Removing CAM from Operation
Make sure you have completed "Removing CAM from Operation". When the
display shows zero bars (in both modes), press ON OFF pushbutton
switch to shut CAM OFF.
