    Charging system using recovery machine



    Hi There

    Can anyone give me a good reason why it would be a bad idea to use a recovery machine to charge a system with refrigerant, apart from the possibility of oil contamination?

    Thanks

    I can't. Since the price of refrigerant has gone through the roof that's the way I do it now to get the dregs in.

    .

    The machine does not know which way it is pushing so if the
    machine can do either direction I see no reason why not.

    I always advise people to push it in with a recovery machine
    especially if you have a lot to do and it is cold, the days of
    trying to warm a cylinder to get enough pressure to charge the system are long gone.

    Suggest that you use a liquid line filter to make sure no impurities get into the system. Otherwise as has been mentioned, it is the best way to recharge a system, especially if you have a lot of gas to put back in.

    Good point and I'd offer you some Luuuuvvve if I didn't have to spread it around
