AC contamination question
I have a new funace and coil. I wish to connect to it an older AC outside compresser unit that I scrapped from a house being demolitioned. The unit was removed and the lines to it crushed down, but not compleatly sealed off. IT has been sitting outside for a year and I am wondering what I have to do to be sure I do not have acid or other contamination inside that might damage my new furnace coil, etc.
How much of a problem is having the compresser lines...open to air? NO dirt is inside, etc. Of course I would have the system evacuated before putting it in service. Anything more I need to do? What are my risks in using this unit? Thank you very much!
