Split System

I really like the system easy to use and perfect for our needs but one thing i have noticed there needs to be a startup sheet in with the instructions todays contractors do not seem to understand the concept of them when I was in the trade we did them on every system we installed now I am trying to get one from them so I can register the unit before time runs out
