I don't have a diagram, but maybe I can help you. You have 2 compressors, o.k. 2 stage system. A single phase contactor? do you mean a single pole, one side breaks, the other is always hot? Speaking of phases, is this a commercial unit with 3 phase? Also, Each compressor needs a separate contactor to carry the load. What is the question?

I assume you know if this is correct voltage and single or 3 phase, and whether it will fit your application or not, how is the duct work going to attach, how many people will be in the conditioned area, what is the building made of, how much insulation is has...
A little more to it than just "turn it on".
If you get the models and serial and can contact the manufacturer or their representative you might get a wire diagram. Most any package unit would do. As long as you keep the original equipment controls. If you "patch" it up it may be hazardous by not having safety's where it was designed for. Or for instance It may have a anti freeze thermostat. By passing this could lead to coil freeze up and compressor damage. Leaving out a pressure switch (if any) may do the same or could become dangerous to people in the event of fan motor failure. A low temperature fan speed switch may not be needed now unless you plan to run the AC in below 55'f.
And a few dozen other factors that might need to be considered.
If you feel confident after this then contact carrier.
Please rate me as high as you can and thanks for using fixya.

Search this web site. It has lots of manuals. It is Carrier site.
Hope this helps. Wiring diagrams are hard to find but I know they are there if you input enough of the right info.
Hope this helps and be patient while you search.
