I have both indoor units mounted. Tomorrow I will put the outside units in.
I was able to get my nitrogen from the gas place I get my CO2 filled. We have a couple fountain soda machines. $10 for a full cylinder and just need to return it when I get my next CO2 filled.That worked out well.
I took a picture of the outdoor unit wiring because I remembered they only color code the outside unit. The number both sides but I had the numbers and the color code.
The one install is not ideal they want it 6” inches from the wall but I wanted it to point out the door so in winter I can open his door when it is real cold. I will let that unit help heat the house the rest of the house.
