Alternate Air Inflator & DIR

[Soggy]

as Dr. Kent Hovind puts it "Ignorance can be fixed . . . stupid is forever"

I prefer the CFD rule..."Can't fix dumb"

Would the isolator usually be open or closed? The valve would just turns off the left tank right, Not the 1st stage mounted on the left post?

I was confused as well when I was first leaning about doubles. I learned what each knob does this way:

ISOLATOR: separates left side from right side
LEFT/RIGHT VALVE: *****think of these knobs as turning off the regulator, not the tank.*****

Therefore a problem with a regulator (first or second stages) can be dealt with by turning off the offending post. A problem with a tank (neck oring, burst disk) is dealt with by turning off the isolator
