You should always familiarize yourself with the equipment that you are working with, but IвЂ™ve included a simple diagram of how to connect the required equipment as well as a вЂњstep by stepвЂќ guide for the newer techs.

There are two typical methods, direct recovery and push/pull. IвЂ™ll cover all this at the bottom of this article, but weвЂ™ve got to start with the basics! I had a reasonably repeatable situation on my hands, and I had the opportunity to try all sorts of things: recovery cylinder size, hose size, hose type, etc. So it was time to install a single valve core in 50 operational units in critical spaces and each of them holding between 50 and 100 pounds of R-410A. This was a possible disaster for an unsuspecting tech, remove the cap expecting a valve core and well. This all originated from some personal trial and error when a manufacturer I worked for had a recall, a missing Schrader core at the receiver service valve (king valve) of all things.
