    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?

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

    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 .

    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!
