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.
Lift the sensor module with the electronic eye by pulling it straight up. Grasp the electrical connector on the battery compartment and pull it out to remove it.
Turn the screw on the battery compartment cover counterclockwise to loosen and remove it. Lean the battery compartment over with the opening down to slide the batteries out.
Insert four new alkaline batteries into the compartment following the markings on the compartment. The negative end of a battery is flat and the positive side has a raised center. Insert each battery with the correct polarity facing down.
Replace the screw on the battery cover and tighten it in clockwise.
Place the battery compartment on the flush valve and plug the electrical connecter into the cover. Set the sensor module on the battery compartment with the electronic eye facing you.
Align the screw holes in the cover assembly, insert the two screws and tighten them clockwise.
