(7) Check oxygen lines for security of connections to mask and generator outlet fitting. Verify that
each mask lanyard and oxygen line are connected to the same generator.
(8) Check the manufacturer's data plate on each oxygen generator for date of manufacture. If date
is twelve (12) years or older, replace generator.
B. Removal
WARNING: WHEN ACTIVATED, THE EXTERIOR SURFACE OF THE GENERATOR WILL REACH
VERY HIGH TEMPERATURES (UP TO 500° F) UNTIL DEPLETION. IF REMOVING
AN UNEXPENDED GENERATOR, TAKE CARE TO AVOID INADVERTANT
ACTIVATION.
(1) Disconnect the wiring harness and remove the mounting tray/drawer from the aircraft.
(2) Remove the screws (3) securing the heat shield over the generator.
(3) Disconnect the oxygen lines from the generator outlet fitting.
(4) Untie the lanyards from the masks. Retain the sleeves installed over the knots for reuse.
(5) If generator has not been expended, place a plastic protective cover over the percussion cap
and coil and secure the lanyard to ensure the firing pin is not pulled during removal and
handling.
(6) Remove generator from mounting tray/drawer.
C. Installation
NOTE: New generators are delivered from the factory with the lanyards and firing pin installed and
the hammer armed. A plastic protective cover protects the percussion cap from being
ignited if the firing pin is inadvertantly pulled during handling.
If the firing pin has been pulled during handling, verfify that the generator has not been
expended and then rearm the generator by pulling the hammer back and inserting the
firing pin attached to the end of the lanyard in front of the hammer. Ensure the firing pin
covers at least 2/3 of the hammer.
(1) Place a new generator into position in
the mounting tray/drawer, ensuring
proper indexing of locator pins to the
mounting brackets - i. e. - two down, one
up.
(2) Ensure that the hammer is in contact
with the micro switch.
(3) Connect the oxygen lines to the
generator outlet fitting.
(4) Place the heat shield over the generator.
Verify insertion of the indexing pin in the
heat shield and secure with screws (3).
CAUTION: ENSURE
(5) Trim lanyard lengths to 30 inches ± 1.
Using a square knot, tie lanyards to the
appropriate masks and cover knots with
sleeves.
