WARNING
To prevent the spread of disease, serious injury and/or death, oxygen breathing systems
must be maintained hygienically clean and free from dust, dirt, and all hydrocarbon
contamination. Refer to oxygen system prework procedures para. 4-10 to avoid violating
this warning.
(1) Close valve (1) on manifold (2).
(2) Remove gage (3).
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.
(3) Apply teflon tape to all pipe threads.
(4) Install gage (3) on manifold (2).
