Freon lines (they are quite small) run with normal domestic insulated piping held in place with styrene foam (aerosol) to prevent vibration. Drain lines also domestic a/c running through electrical conduit bends to keep shape. Removed section of wall ply (lots of staples!) in bathroom to run lines, electrical & drain inside wall for main room unit. Bedroom ones run in plastic a/c ducting normally used outside of house (see LHS of window). Dropped underside coreplast to run lines, etc from one end to the other. Did not have to use anti-vibration mounts as no noise or vibration when getting to sleep. Easy install!
