(3) Slide the fully charged cylinder into the carrier, with cylinder valve gauge facing away from the
backplate, then align the retainer into the dove tail (if equipped).
(4) Close the latch mechanism until the buttons lock in place.
NOTE: Be sure that the latch is closed when a cylinder is installed.
(5) To check that the cylinder is secure, place one hand on the backplate and grasp the cylinder
valve with the other hand. Try to pull the cylinder and valve down and out away from the carrier.
Make sure that the band and latch holds the cylinder securely in the carrier.
NOTE: If the cylinder feels loose, check that the latch engages with the proper slot on the band.
Ensure that the latch is fully tightened. Do not use the SCBA if the cylinder is not held securely in the
carrier.
(6) Align the handwheel assembly to the cylinder valve.
WARNING!
Care must be taken to protect the quick connect coupling and adapter from damage, dirt, and debris
during cylinder replacement. Dirt and debris can cause the cylinder connection seals to leak. Visually
inspect the coupling and adapter prior to connection. If dirt or debris is observed, the material must be
removed prior to connecting the cylinder.
