I want to install a new LG minisplit Heat/cool unit for a new construction office. My question pertains to the lineset. The indoor unit says it can be mounted with 8" of clearance from the ceiling. The lineset is 50' long and I want to run the lineset up the wall about a foot and then over through the ceiling trusses horizontally for about 30', then down a wall about 10' to the outdoor unit on the other side of my attached garage. Does this sound reasonable? The installation diagram shows the lineset running down to the outdoor unit? Also, can I run the condensation tube separately from the lineset or does it have to be combined with the lineset?
