The control panel can be mounted either inside or outside the dwelling.
For outside installations, the control panel is to be mounted on a 2" X 10" pressure treated board (Figure Below). Placement of the control panel should be from 1-2 feet above the ground and about 3-5 inches away from the side of the house (Figure Below).
For INSIDE installations, the control panel is to be mounted on a piece of plywood so the control panel is not mounted directly to the concrete basement wall.
