    You can probably call it the carrier tech support for that if it's a really long mine said it will be a different orifice size recommendation. It was over a hundred feet it'll be different than what comes for with it with a 2-ton coil. You can always put it expansion valve in there. If you can get a PDF on the condensing unit and the air handler it might be in there also that orifice that you need

    Do a Google on your model numbers of the air handler and the condensing unit and see if you can get a PDF if not get ahold of carrier

    Have a update—
    Carrier tech support called and back and said, 56 or 57 - depending on what indoor coil it is.

    Product Data manual stated - #57 indoor piston and #46 outdoor piston (heating).

    If you want the manuals, let me know and I will email them to you.
    Instead of learning the tricks of the trade, learn the trade.
