SECTION 8
HANDLING, SERVICING AND MAINTENANCE
Replenishment procedure
MAKE SURE THAT THE AIRPLANE IS FITTED WITH A GROUDING CABLE AND IS
THE OXYGEN CART MUST BE ELECTRICALLY BONDED TO THE AIRPLANE.
DO NOT OPERATE THE AIRPLANE ELECTRICAL SWITCHES OR CONNECT/DISCONNECT
GROUND POWER DURING OXYGEN SYSTEM REPLENISHMENT.
DO NOT OPERATE THE OXYGEN SYSTEM DURING REFUELING/DEFUELING OR
PERFORM ANY OTHER SERVICING PROCEDURE THAT COULD CAUSE IGNITION.
INTRODUCTION OF PETROLEUM BASED SUBSTANCES SUCH AS GREASE OR OIL TO
OXYGEN CREATES A SERIOUS FIRE HAZARD. USE NO OIL OR GREASE WITH THE
ALWAYS OPEN SHUT-OFF VALVE SLOWLY TO AVOID GENERATING HEAT AND
REPLENISH THE SYSTEM SLOWLY AT A RATE NOT EXCEEDING 200 PSIG (13.7 BARS)
REPLENISHMENT OF THE OXYGEN SYSTEM SHOULD ONLY BE CARRIED OUT BY
The cylinder full charge is assured for a pressure of 1850 PSIG (127 bars) at a
temperature of 70° F (21° C). If the cylinder temperature differs from 70° F (21° C), refer to
Figure 8.7.4 which lists the required pressures according to the cylinder temperature.
Open the oxygen service door on the R.H. rear karman.
Measure the oxygen cylinder temperature.
Make sure the thermometer indication is constant. Note the indication.
Refer to the temperature/pressure chart for the correct oxygen cylinder pressure.
If the pressure on the oxygen cylinder gage is lower, fill the oxygen cylinder.
Make sure the area around the oxygen cylinder charging valve is clean. Remove the cap from the charging valve.
Make sure the oxygen supply hose is clean and connect it to the charging valve.
Slowly pressurize the oxygen cylinder to the correct pressure.
Close the oxygen supply and let the cylinder temperature become stable.
Monitor the oxygen pressure on the gage and fill to the correct pressure if necessary.
Release the pressure in the oxygen supply hose and disconnect from the charging valve.
Install the cap on the charging valve.
Make sure all the tools and materials are removed and the work area is clean and free from debris.
Close the oxygen service door.
