    HELP! I'm new and may have damaged r22 compressor

    So I'm new to the field and just changed out an evap coil. I pumped it down triple evacuated it. I turned the r22 bottle upside down to do so.(Is this necessary or hurt anything?) The problem is that I don't have power hooked up in the breaker so I chared the unit while its off. I put in 3 1/2 pounds right into the suction port. *When it gets power is the system going to be damaged?

    Yes you just ruined it!

    No settle down take a breath. It will be fine. I rarely ever charge vapor ( you can't on blends)

    Chared? As in: burned?

    Or Charged? As in: I'm short on small G's right now ?

    You "pumped it down"?
    Does that mean" into the condenser of the system?
    Or does that mean: into a recycle cylinder with a recovery unit?

    Why was the breaker to the condensing unit not wired just to change out an evaporator coil?

    What is the system charge in total?
    What percentage of the total system charge does 3 1/2 lbs. represent?

    PHM

    The conventional view serves to protect us from the painful job of thinking.

    3 1/2 #'s of liquid isn't going to help!

    Better get some one out there to help before starting that pump

    Charged.

    Yes it was recovered into recovery tank. And then after new coil was put in I vacuumed it down.

    The breaker is kind of a weird story. Long story short one of the owners unhooked it. I told them to put it back because it was unnecessary and also not my job.

    The factory charge for the unit said 56oz. Its a mobile home so I wouldn't think it's need too much.

    So it won't damage the compressor putting all that in the suction side?

    Do you have your epa 608? If so keep posting and apply for Pro membership. This is a great place to learn. I'm sure it will be ok as stated. I never charge vapor either especially with blends.

    How did you get the full charge in there without it running?

    Did you have the disconnect pulled and locked out while working on it?

    I'm not sure if that's unusual but it took 3 1/2 pounds turned off. It did it fast too, probably within a minute or 2 max.

    The unit didnt have power to it
