Thanks for that shot Dave.
Just curious, that's a shot of the oxygen side? The shut-off is on the intake side or the output side? And where does the third hose go to?
Thanks in advance.
Tom
Hi Tom,
Yes that's the oxygen side.
I guess the shut off will feed the Solenoid, one hose from first stage to Manual add and second hose for off-board, I guess.
Will not know more until I do my course and to be quite honest, apart from sorting out the harness etc I will be leaving it alone.
I have often heard various people say that if you are trained and have a good knowledge of CCR then you should be able to teach yourself a unit. DrMike has always argued against this and I have always agreed with him, both the Ouroboros and the Sentinel are complex units. They require proper training and instruction, so I am looking forward to my time with Al, I'll certainly be getting my money's worth out of him.
Cheers,
Dave Cooper.
