WARNING
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.

WARNING
Leave 1 1/2 threads exposed on fitting when applying teflon tape. This will ensure that no teflon tape will

blockage of the air system and subsequent possible injury or death to the diver.
