    R-22 to R-410a conversion; distributor nozzle sizing?

    When converting an evaporator from R-22 to R-410a and there's a distributor nozzle, do you replace the nozzle when the TXV is replaced? If so, what would be the effect of not replacing the nozzle?

    Sorry, never mind, Sporlan Bulletin 20-10 answered my question.

    If you're talking about the orifice/metering device (piston) it should be removed entirely if you're installing a txv.
