What happens when a vac is not properly pulled?
I noticed that my helper was using the 3/8 hose on the manifold and forgot to cap the other port on the vac when we got to the second job. Can I suck the Ref (410A) back into the compressor and pull a Vac or is the Ref (410A) contaminated?? The unit was running a little high but it was condensing a lot.
What should I do???
