A/c system

with a manifold gauge, recover tank and a vacuum pump what else is needed to safely

recover r-134 from a system. and what is the correct procedure for this.

You need a refrigerant recovery machine to correctly reclaim the refrigerant. The vacuum pump doesn’t produce enough pressure to convert the refrigerant from a gas to a liquid. And using the vacuum pump to transfer the refrigerant from the vehicle to the recovery tank will result in burning up the vacuum pump.


I agree. This isn’t a DIY job.

Sooner or later, it all gets released into the atmosphere anyway…What are you trying to do? What is your end goal?
