yep, your screwed. Reclaim, pull a new vacuum......CHARGE THE SYSTEM.....open the valves THEN start it up.

how long did it run without freezone in it?

[zman420]

i charged it, it has freon ,but the nitrogen from the condensor is also in it mixed? i was in a hurry and screwed up

[zman420]

Do I need shut it down asap?

[jmac00]

Do I need shut it down asap?

YES !!!!!!!!!!!!!!!!!!!!! your running this thing with R-22 AND Nitrogen in the system??? How long has this been running???

Reclaim whatever you have in there, pull a vacuum, recharge and restart and hope the system last a few years

[zman420]

I ran it for for an hour or so and then the t stat at 75 its been 4 hours now

Uh oh

[jmac00]

Uh oh

that would be an understatement LOL, i think Zman may have killed the patient. This can't be good.

You need to empty the system and start over.

The R22 in there is no good now

Open both king valves and leave them open , you are done using those now.

Using the shrader valves , reclaim the bad gas , vacuum it down , add new R22 , done .

Is this for real? Between this and fengHVAC I'm starting to think someone is pranking the members.

With 420 in the username it is probably easy to forget something like that.

[Brent Ridley]

Do as stated above ASAP!

Do not operate the system until you have recovered contaminated charge, pulled a vacuum to below 500 microns, and weighed in the charge using the correct refrigerant.

Failing to do so will cause that system to fail VERY soon!

I'm sure that's just dinner time lol

Zman,

I was checking your previous posts and you stated you've been in the trade for 25 years? You were inquiring about a Florida contractor license.

I understand accidents happen but with that many years experience, you should know exactly what to do!

I'm kinda confused.

[SBKold]

Relatively easy to seperate the two in a cylinder.

Oh and did this happen before or after 4:20pm on Friday?

Ill go ahead and admit doing the same thing before. I thought I read serial and saw 0911 and thought I had a older 2009 unit. Oops.

[jmac00]

not me, the guy has to be a troll, 25 years and he pulls this???

something is definitely not right here

[Brent Ridley]

I was trying to put it nicely. Haha. That post was from 2011...so he should have 27 years experience now!

When are people going to learn? The key is to be humble and truthful. If you possess these things, you'll gain more education from this site than you've ever dreamed of! I sure know I have.

But if you do the opposite, we aren't so willing to help and you will get run off quickly.

See.....! now some people are already suffering the repercussions from chasing Feng away. Had he been here to lend his master tutelage in the hvac, this poor soul would never have been in this predicament in the first place.
