DO NOT switch CAM OFF when one or sore bars are showing because this
action stops the purging of any contaminant remaining; this would
extend the wars-up time on future use.
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
e. Observe Display (6).
If display 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 40€ F (4€ C),
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 2-11).
Removing CAN 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.
