For most of the day the unit is quiet,until much later in the day,then a vibration noise begins,& gets louder. Sounds like a pipe vibrating,but appears the 3/8" copper line is clearing. The unit is 6 inches away from the Wall,& instructions state 12 inches to prevent overheating. Any help appreciated... Thanks

Call the installer, not much we can do from afar
