8. Install the bobbin into the housing (Fig. 9), white side up, aligning
the slots on the bobbin with the ridges inside the threaded

9. Install the cap by screwing clockwise until it meets the
housing shoulder.
10. Check the new cylinder/bayonet assembly to ensure the o-ring is
in place and the sensor ring is attached (Fig. 9). Ensure that the
CO cylinder has not been pierced (Fig. 8).

YOU WILL DAMAGE THE SENSOR RING IF BOBBIN AND CAP ARE NOT
INSTALLED FIRST.
11. Push, and hold, the lever into the inflator housing. The pull-cord
should be situated in the groove (Fig. 9). Install a new cylinder/
bayonet assembly by engaging bayonet tabs in housing, pushing
in, then turning clockwise 1/8 turn to a full stop (Fig. 9).
FLOTATION DEVICE WILL ONLY INFLATE IF CYLINDER IS TURNED TO A FULL STOP.
12. Examine the service indicator (Fig. 9) and ensure it is GREEN. If
the service indicator is red, the mechanism has been fired or is
incorrectly fitted and the inflator requires service.
13. Ensure you have successfully re-armed by performing a leak test
(see "Care and Maintenance/Every Six Months," page 16). (If the
cylinder is improperly installed, the o-ring won't make a proper
seal and the air will leak around it.)
