Heat Pump Installation?

I recently bought a newer, off-brand heat pump system from a guy that had it in storage and never hooked it up. It was such a good deal I couldn't turn it down. The problem is that I know nothing about how to hook one up, and what is needed. What I got was the unit that sits outside and the a/c coil. We have an upflow propane furnace. My question: Is there any additional parts that I'm lacking to join one to the other? (aside from the obvious wiring and tubing) Thanks for your time. Dan
