| 2 O2 and Dil manual add's! OK, so I'm new to the silent world. I bought my unit 2nd hand, it is basically standard, well was until I got hold of it.
Now the question is :-
I have 2 manual diluent adds, and 2 manual O2 adds, why?
Is there not enough onboard gas? I know that answer, but why have a 2nd of either let alone both?
Would it be usefull? I've blanked them off as it was getting confusing on my course. |
