5.2.5 Actuating Levels*, Steam Service Ratings and Specific Gravities

For float operated units, minimum specific gravities and actuating levels vary depending upon the

material of construction code used with the unit.

NOTE: The minimum specific gravities and actuating levels shown are for single switch units with 1" process

connections only. Minimum specific gravities and levels will change for multistage units and levels

*The level decals on the control identify the actuation levels for units with three switches at the corre-

sponding minimum specific gravity of the three switch configuration.
