NOTE:
Oxygen clean fittings come from a sealed package labeled for oxygen sys-
tem installation. Make sure that you use only oxygen clean fittings. Some
fittings used in the oxygen system are the same as fittings used in other
systems that are not oxygen clean. If it is necessary to clean parts, use the
applicable oxygen procedures to clean the parts. This also applies to tube
caps and plugs, which must be as clean as the installation connections.
WARNING:
USE ONLY OXYGEN CLEAN COMPONENTS IN THE OXYGEN SYS-
TEM. IF YOU DO NOT USE OXYGEN CLEAN COMPONENTS, A FIRE
OR AN EXPLOSION CAN OCCUR. THIS CAN CAUSE DAMAGE TO
EQUIPMENT OR INJURIES TO PERSONS.
