Hi Peter,
You are referring to the 38HDL model. Unfortunately, these are now obsolete.
Is this an existing system that needs a replacement condensing unit? Ductless Split?
If you need to replace with a 'standard residential-type C/U' you will be looking at the 24ABS (in order to retain the use of R-22). If you are looking to replace the C/U portion of a Ductless Split, your only option is to go with a new R-410A system (ie. 40QNC/38HDF, or 40QAC/38HDR).
Hope that helps.
