The lines will go through the closet to reach the exterior wall, and I’d like to fasten them up to the closet ceiling, protected and out of the way. So I’ll be adding a condensate pump to this room, and one other. I can power the pump from the indoor unit.
Question: the hi and low pressure lines don’t care about the slope of lateral runs, correct? I.e. they can leave the indoor unit and go up before they exit the exterior wall and turn down?
