Need serial # for build date & location, not model #.
The model # indicates unit characteristics including capacity not the serial#. The serial # generally tells where , when , by whom and what components were used when it was made.
Wild guess here... Goodman dealer? Goodman.com? Try a Google search on Goodman manuals, you will need the complete model and serial #`s for what you are looking for no matter where you go.

5tonne
That is a 3-ton A/C. I used to have a Goodman ck36-1b model that was installed in 1996, and was just replaced last week with a newer Goodman.
The Goodman model CPKE48-1B typically has a cooling capacity of 4 tons. This is indicated by the model number, where "48" generally refers to a cooling capacity of 48,000 BTUs, which equates to 4 tons (since 1 ton equals 12,000 BTUs). Always consult the specific product documentation or manufacturer's specifications for precise details.
