What is the best way to check oil % in a system?
I have a McQuay ALS 425A with 2 comps D.O.A. I would like to save the other 2 that had leaks I had to repair leaks and added 25% of the circut charge. McQuay is telling me that the oil is mineral but its poe,even after I give them the Part # blasted all over the unit they still insist I am wrong.
The cost of repairs to the other 2 comps is going to be close to compleat replacement so If I can Keep 2 going till that can be accomplished is my goal.
