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

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.

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!
