Recharge after recovery question.

[lilroud]

Ok, ill admit it, been awhile since i have been on the job, starting a new job Monday with a local company, and im having a brain fart... I know how to properly recover and what levels to bring the system down to, but after a repair of a leak or other repairs that require a recovery and evacuation of a system, in order to get the refrigerant that you originally recovered from the system back to the system from my recovery tank, i just reverse my hoses on the recovery machine? Such a newb question i know... Thanks

I would simply connect my manifold to the recovery tank and charge from there, no need for the recovery machine. And if you remember your EPA stuff make sure the tank only contains used refrigerant from that customer's unit, you cannot use it in another owner's unit without proper recycling so if it contains refrigerant from other properties you better use a virgin tank.

you dont know how to get gas out of a recovery machine?......just hit the reverse switch on the recovery machine. Next to the flush valve.

Usually this type of issue is like driving, you get cold feet and butterflies everywhere before you face it, but then once you are on it your body starts moving automatically just like good old days and before you realizes you are in same thing over again. get the hex key out turn off the dis tap and suck till - and switch off immed. if you got a leaked skipped current.

It's true, when you have a pretty long break from work, you start to "lose" some of the usual work methods you were used to--trust me, it happens to everyone. But once you get back into the swing of things, you'll be back to business in no time Just takes some time first.

Of course, one should test to see if there is any acid in the refrigerant, in case there was a burnout in that unit that eventually killed the compressor, etc.

I use the Qwik-test kit for that check, before I consider re-using refrigerant.

Make sure you only use liqiud and run it through a filter drier. That will keep any non-condensables out.

When you run into a leaker and don't really know any history on the unit or who has been working on it the possibility exist that if the unit has been worked on several times the refrigerant is already contaminated. First run a P/T Test on the recovered gas. If it checks OK then acid test oil/gas mix. If still OK pull a good vac. Charge thru the Liquid Line off the liquid side of the tank thru a drier. You would be amazed how much air and moisture you will find in some operating systems

Personally I only use virgin gas. Time is money...period. You have to spend the time with your analysis drives up the customers cost. Cover your backside, do your customer justice and leave the refrigerant history and the chem analysis up to the recyc company in the end game you will have done the right thing by your customer and your employer.
Why are you leaving your rec. EQ attached while charging anyhow? Recover, purge, "cut the cord" and treat the recovery tank as you would a virgin tank depending on its type 22,410a. Our goal isnt saving time afterall.
