The tabs on the outer casing must fit in the U-shaped slot on the housing assembly. Slide the outer casing onto the assembly until it is approximately 1/2” (12 mm) from the face of the door. Then drop the casing down approximately 1/2” (12 mm), push casing toward door so that it is flush with the door surface (approximately ½” or 12 mm), and lift the casing approximately ½” (12 mm).
