    Bruce, look up "true r290 training" on you tube. Pm me your email, and I will send you some stuff.
    But, yes, standard gauges and vac pump. You purge with nitro before brazing. You add a piercing valve to service the system, and remove it when done.

    Standard stuff is fine.
    They want you to run a combustible gas detector while working since you can't smell 290

    I forgot about that. If you get the true kit, you get a gas leak detector, r290 and adapter hose, a pinch off tool, and a sign you are supposed to put up that says "danger propane" or something like that.

    Isn't there a special certification needed for this stuff?

    No. I've completed an RSES course which is recognized but is not required by Ashrae, Epa or fire Marshall.
    Just gota realize no unit is manufactured with more than 5.5 ozs I think.
    So no big deal,useing a can of mapp gas is more dangerous

    I used to air my tires up with it. The EPA and Dupont had their day. This all started up north, but after all these years they can't afford the cause they started. This is a good thing.

    R290 has no odorant, because the odorant is acidic in a refrigeration system

    That will be fine for a while James. But Like coldsnap said, but the oder additive is dimethyl disulfide. A sulfer compound that will concense to a form of a sulferic acid
    You white people sure can mess up a good thing.
