3.3.9 LEAK TEST OF SCBA:
Remove the CDV from the SCBA by unscrewing the CDV from the facepiece or hood. To do this turn
the CDV counterclockwise and pull it out of the facepiece or hood. On the First Breath CDV, push
button "in" prior to removal. With the CDV disconnected from the facepiece or hood, open the cylin-
der valve and place the test cap over the CDV outlet port. Do not seal with test cap until air flow has
begun. Allow the pneumatics to pressurize and then close cylinder valve. Lightly place a finger over
the hole in the test cap to restrict air flow. The needle on the pressure gauge should not fall more
than 1/8 inch per minute. Remove the test cap to drain pneumatics.
3.3.10 Connect CDV to the facepiece or hood. Pull gently outward on the CDV to ensure it is
docked properly.
3.3.11 Return apparatus to storage, or proceed to donning instructions.

If any of the tests listed above fail, remove the apparatus from service, tag and return for repair
by authorized personnel.
WARNING
NOTE
The CDV flows a very small amount of air past the pilot jet. The test cap has a small hole to allow
the air to escape. It may be necessary to hold the test cap in place while performing the leak test.
Complete all routine checks and inspection procedures outlined in Section 3 before starting don-
ning procedures provided in Section 4.
IMPORTANT
NOTE
After every 100 hours of use, or at least once per year, the entire SCBA should be taken out of
service and tagged for comprehensive maintenance by an authorized, trained technician.
