REPLENISHMENT PROCEDURE
WARNING
MAKE SURE THAT THE AIRPLANE IS FITTED WITH A GROUDING
CABLE AND IS PROPERLY GROUNDED.
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 OXYGEN REPLENISHMENT
EQUIPMENT.
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) PER MINUTE
CAUTION
REPLENISHMENT OF THE OXYGEN SYSTEM SHOULD ONLY BE
CARRIED OUT BY QUALIFIED PERSONNEL
NOTE :
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 9.37.3 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.
