incoming power or motor wiring must be reversed.
3.
Do read and follow procedures
before attempting to energize actuator.
4.
Do cut off electric power before opening switch compartment.
5.
Do install pressure relief vent in highest point of gearbox.
6.
Do use stem covers
of sufficient length to protect valve stem.
7.
Do clean Electrical Enclosure flange
thoroughly & lightly grease before closing.
8.
Do secure all Electrical bolts.
9.
Do follow an annual maintenance procedure.
10.
Do use caution
when working on, with, or around valves and actuators. You are
