My answer to your question above was:

HOWEVER, the instructions for startup I was given was incorrect! Randen your first response was the answer. The compressor was going in reverse.
Today my brothers HVAC friend suggested like Randen that it maybe going in reverse. When I told him how we were instructed, he said that the condenser and blower fans are not 3 phase and wouldn't go backwards anyway. He suggested I switch the phases.
After switching two phases, it started heating the space
and without the heat strips. The compressor was a lot quieter too! I hope we didn't ruin the compressor? Also is there a proper way to test and see if the phasing is wired correctly?
Thank you to Randen and Jeff5may for your assistance getting this unit up and running again. Speaking for my friends, they are also very grateful. It was really neat to watch a couple of older (70 year old) men happy and excited today about having heat in their hobby shop as they call it. 32*F outside and 60*F inside, they are "Happy Okies" he said.
