4.1 Standard Mounting The following procedure outlines the steps necessary to install the switch: Mount the switch to the chamber where you want the switch to trip. The switch should be mounted 90° from the indicator assembly to insure optimum magnetic coupling. The float must be cycled past the switch in both directions to insure that the switch will operate properly when put into service. -
