For float operated units, minimum specific gravity andactuating levels vary depending upon the material ofconstruction code used with the unit.
For displacer operated units, minimum specificgravity and actuating levels vary depending upon thetemperature at which the unit is operated.
NOTE: The minimum specific gravity and actuating levels shownare for single switch units with 1" process connections only.
Minimum specific gravity and levels will change formultistage units and levels will change for units with11⁄2" or 2" process connections. Consult factory for thesechanges.
