WARNING
Cleanliness is imperative in maintaining and handling diving air system components. All tools and parts

this manual. Foreign substances within an assembly could result in equipment failure and possible injury
or death to personnel.
Ensure that all air lines and components removed or openings into the air system that provides breathing

contaminated and could result in injury or death to the diver.
