Mini split total pipe length calculation
We are trying to select a mini split system for our house. I was reading the Fujitsu Halcyon system manuals, and there is something not clear to me in copper pipe length calculations. Each connection from an outdoor unit to indoor unit (or branch box) is composed of two copper tubes: A liquid pipe (1/4"), and a gas pipe (3/8").
The maximum allowed pipe length between a branch box and an indoor unit is 50 ft. Does it mean that the pipe distance between the branch box and indoor unit should be less than 50 ft, or should it be less than 25 ft ( 25 ft for each pipe) ?
So, the question is: Do we add the length of all copper pipes between two units while calculating the total pipe length distance?
