PFC Operation Manual 

Safety Alerts Defined, Continued 

Preview and understand the safety alerts used in this manual before operating or performing any 
work on the PFC. Safety warnings are provided in this manual before each step that may involve 
hazards to personnel. See the following safety alert icons and text for information on icons, 
which identify potentially hazardous situations/consequences of not avoiding the hazard. Safety 
alerts used in the manual and on the equipment follow ANSI Z535 and use the signal words 

DANGER, WARNING or CAUTION.
