This is the question we were concerned with.
If you had an 80psi reading with the first can of refrig., you did not have a
valve open and your gauge was showing can pressure. The comp did not come on b/c there was never any refrig in the system yet. With a fully vac system, one can would not give you a system pressure of 80psi.
But when you did it the second time you posted , you noticed the can got cold..it got cold b/c you now had refrig. going into the system. So, the logical conclusion is you did not have the correct charge ports open the first time around.
That was our question.
But, you now have the system charged, so..nevermind.
