proper way to recover r-22?

[axeman]

most recovery machines are colored coded like your gauges. Blue means suction or low side on your gauges and is the inlet to the recovery machine. Red is the liquid or discharge pressure gauge - on the recovery machine (red)is the discharge to your recovery tank. You will use the three hoses from your manifold gauge set and need one additional hose to connect the recovery machine to the D.O.T. Recovery Cylinder/Tank. Make sure you dehydrate (vacuum)the recovery tank first and you don't mix refrigerants. Hook your blue hose to the service valve on the large copper tube and your red hose to the small copper tube. Open all valves and recover your refrigerant until you reach required level.
This task is not for beginners becuase you can damage the recovery machine or yourself. I guess your going to attempt to recover or blow the charge no matter what, so I figured I would give you some basics

Hey Dice, now I know why you got that 9mm. It may be time to upgrade to a Howitzer.

There are plenty of tips for recovering freon.


If I had access to ice, what I would do if I were you... I would keep a recovery cylinder ready to use and have a big like .. horse bucket feeder .. they look kinda like a large twenty gallon wash tub. I would get something I can lay in some ice, then a layer of salt and so forth. I would have my cylinder in the midst of this salt and ice.

With one hose attached, I would pull down a small residential system in no time.

Leave it on it's own whil you go and do other work.

This is recovery without having to use a machine.
Then to finish up, I might hook up the recovery pump for just the very last few ounces of refrigerant.

If I felt so inclined.


But that ice with salt will lower your recovery tank temperature so low .... that freon will be walking all over itself just to get inside your tank.

Seriously, this works. And it's foolproof. And it does it's job without you having to stand there while it's working.

I suppose some of us were born with the knowhow to hook up a recovery machine.
When does one cross the line between being a newbie and become an experienced technician?
Is it after one aquires a set of gauges, an acetylene torch, a micron gauge...what? what really sets us apart?

At least the guy is trying to get the knowhow by asking.
I think thats commendable.....

As for loosing it so soon and giving all that xxx material...I don't know

They teach it in school. They teach how to recover and how the HVAC equiptment operates. Do they teach everything? No they don't but they teach the basics. Now for a newbee that did not go to school he should be with an experienced tech. I do give him credit for asking but his response wasn't called for. If you are a tech then you will know how to recover. If you a newbee without your license to recover then you can't and shoudn't touch it. BUT if you have your license you know how the proceedure is done.

All he had to do was read the book and look at the little diagram. I think he needs to increase his blood pressure medicine.
