In the near future I've got two Argosies that need the dash A/C installation completed and I'm looking for advice on how to go about finishing up the installation
On my Argosy I will be done with the hose installation next weekend at which point I will install Peanut's hoses.
A) Both have new compressors, both of which came with the manufacturers recommended amount of oil.
B) Both systems have all new components with the exception of Peanut's evaporator which is original and untouched. My evaporator has been cleaned by a radiator shop.
This is the first time I've dealt with a totally new and empty A/C system so I have some questions on what steps to take next once the hoses are installed. I know one of the next steps is to draw a vacuum on the system and I've got a good vacuum pump to perform that task.
The first question is since the compressors have been pre filled with oil won't pulling a vaccum suck that oil out?
If so then why do manufacturers send the compressors with oil? If not please explain why not!
Assuming it's acceptable to just go ahead and pull the vacuum how long should I vacuum the system and (assuming everythings tight) how long should the system hold the vacuum once the pump is off?
Assuming it holds a vacuum for X amount of time is this the point where you actually charge the system with freon and oil?
Thanks!
