Just curious....On your second picture, are these condensing units mounted far enough away from the wall for adequate air flow? And..your HP/LP switch could be located on the base plate as vibration up high, as you have it currently on the plastic electrical box, may cause premature mechanical failure.
Thanks for posting pictures.
