b	Net buoyancy of float has been calculated with float 80% submerged, thus allowing 20% factor of safety.

c

Buoyancy data above is calculated for use in water. Consult factory for buoyancy data media having specific gravity different than water. When ordering Float Accessories, first specify the desired Float Accessory Package such as 9049A6, 9049A6CS, etc., then as a second item give the number of additional rod kits required. For Example: To get a 9049 A6 with 15 feet of rod, order as follows: Item A (1) 9049A6 Item B (4) 9049T1

Refer to page 22-20 for Float Accessories.

The Class 9036 Type FG30 pedestal style float switch is designed for liquid level control with electric motor operated pumps either directly or through a magnetic starter. It can also be used to activate alarms in liquid level control systems. The upward or downward movement of the lever arm of the Class 9036 Type FG30 float switch controls the ON and OFF positions corresponding to the water level changes required to turn the pump or alarm on and off.
