WARNING
Cleanliness is imperative in maintaining and handling diving air system components. All tools
and parts must be kept free of oil, grease, rust, or other contamination in accordance with
accepted army diving cleaning procedures. 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 air are covered with a plastic bag and secured with a rubber band or taped shut. Small
components should be stored in a plastic bag and sealed. Failure to do so will cause air system to
become contaminated and could result in injury or death to the diver.
(b)
Loosen coupling nut (3) and move condenser (4) out of way.
(c)
Remove adapter (5).
WARNING
Leave 1 1/2 threads exposed on fitting when applying teflon tape. This will ensure that no teflon
tape will hang down inside the air system. Teflon tape should be wrapped in such a manner that
when the fitting is tightened the tape will not loosen. Failure to wrap teflon tape correctly may
result in contamination or blockage of the air system and subsequent possible injury or death to
the diver.
(d)
Apply teflon tape to threads on adapter (5).
