Sloan manufactures flush valves for commercial toilets and urinals with electronic eyes. The eye senses when you enter a bathroom stall or the area and when you leave to flush the toilet automatically without touching it. The sensor range is fully adjustable to ensure the correct flush cycle in an area. The eye is battery powered and requires replacement batteries occasionally. A light flashing four times quickly when a user steps into the eye range signifies low battery voltage and the need for replacement.

Insert a screwdriver into one of the two screws on the flush cover assembly. Turn the screw counterclockwise to loosen it and pull it straight out. Repeat this process to remove the second screw. Pull the cover assembly straight up and set it aside.
