Hello Dennis, thanks for reaching out. The Air Distribution Box # ADV48SR will work with any of the 2025 or newer Advent AC units that use the new R32 refrigerant. The part in your picture appears to the Advent ACM135. This part number is an older unit that uses the old R410a refrigerant. If this is what you have, this would not be compatible with the # ADV48SR distribution box.
The distribution box you would need is Advent part ACDB, but sadly this was discontinued when they switched to the R32 refrigerant. So unless you can find the ACDB elsewhere, the only solution I can offer would be to get a new R32 AC unit.

Hi Jesse Thank-you for the clear explanation. Any suggestions on where I can find an Advent part ACDB distribution box? The AC is new and I cannot return it. Dennis
