Be sure to tighten the lever when mounting it. To maintain the seals around the mounting screws, O-rings have been supplied with the switch. Insert each O-ring and secure it with a lock nut. When routing wires into the conduit opening, be sure that no wire cuttings or other foreign matter enter the switch.
