NOTE: As far as still available at the Airbus final assembly line a few aircrafts have

already been reworked before handover to the operator .Those units have

been marked with a green dot on the test button label as shown below and do 

not need further rework.

B. CONCURRENT REQUIREMENTS

For 1XC15-0100-Series Oxygen Container - Not Applicable

For all 1CX22-0100-Series Oxygen Container 

This SB requires the simultaneously accomplishment of the Service Bulletin No. 

1XC22_0100-35-006.

C. REASON

During manufacturing at the manufacturer facilities particles had been detected in the 

oxygen generator manifolds. Investigation revealed that those particles (chips) are chafed 

from the mask hoses when installed onto the generator outlets. It was found out that a 

defective mask hose installation device has caused the chips. Such chips may reduce or 

block the oxygen supply .

F. ASSEMBLY

WARNING: STRICTLY OBEY THE PROCEDURES FOR USE OF OXYGEN 

EQUIPMENT. DO NOT USE ANY OIL, GREASE OR OTHER 

LUBRICANTS MADE FROM PETROL IN THE WORK AREA OF THIS 

OXYGEN EQUIPMENT. THIS CAN CAUSE A DANGEROUS FIRE 

HAZARD RESULTING IN SERIOUS PERSONAL INJURY OR DEATH.

CAUTION: IN GENERAL THE WORK ON OXYGEN EQUIPMENT REQUIRES THE 

USE OF LINT-FREE GLOVES. HOWEVER SOME STEPS OF THIS 

REWORK MAY BE HINDERED WHEN WEARING GLOVES. 

THEREFORE THIS REWORK IS RECOMMENDED TO BE DONE WITH 

DRY AND CLEAN FINGERS. ENSURE YOUR FINGERS ARE DRY AND 

CLEAN.

(1) Installation of the Manifold

(a) Put a new O-ring in the first groove of the oxygen generator outlet port 

(See Figures 19 and 20).

Figure 20 (15 Min. Unit shown)

CAUTION: ALWAYS USE A NEW MANIFOLD. A DEFECTIVE MANIFOLD

MAKES THE OXYGEN GENERATOR UNSERVICEABLE.

CAUTION: ENSURE THAT THE MANIFOLD IS EQUIPPED WITH A BLUE 

SILICON RING USED AS A SAFETY RELIEF VALVE AS SHOWN 

IN FIGURE 4.

(b) Move the mask hoses over the recessed part of the manifold fitting as 

shown on Figure 21

(f) If necessary, use a new spring loaded disc PNR E61063-00.

CAUTION: MAKE SURE THE SPRING LOADED DISC PNR E610632-00 

HAS THE CORRECT POSITION. THE DISC MUST BE 

INSTALLED WITH THE COMPRESSION SPRING FIRST INTO 

THE MANIFOLD. IF THE DISC HAS NOT THE CORRECT 

POSITION THE OXYGEN GENERATOR IS NOT 

SERVICEABLE.

(g) Put the assembled disc with the compression spring first into the manifold.

CAUTION: DO NOT APPLY UNCONTROLLED FORCE TO THE MANIFOLD 

DURING INSTALLATION AND EXERCIZE CAUTION TO THE 

O-RING PNR E20274-06. TOO MUCH FORCE CAN CAUSE 

DAMAGE TO THE O-RING. ENSURE THAT THE GROOVED 

PINS ARE IN THE CORRESPONDING RECESS OF THE 

GENERATOR OUTLET. THE GROOVED PINS MUST NOT BE 

PUSHED INTO THE O-RING RECESS. A DEFECTIVE O-RING 

MAKES THE OXYGEN GENERATOR UNSERVICEABLE.

(h) Carefully install the assembled manifold on the generator outlet port. Do 

this by slightly turning and pushing (See Figure 28). Make sure you do not 

cause damage to the O-ring PNR E20274-06.

(i) Attach the manifold to the generator outlet port with two grooved pins 

PNR E71070-00. 

(2) Installation of the Oxygen Generator into the Container

CAUTION: EXERCISE CAUTION WITH THE MASK LANYARDS DURING 

INSTALLATION OF THE OXYGEN GENERATOR.AN 

ACCIDENTAL PULL CAN REMOVE THE RELEASE PIN FROM 

THE OXYGEN GENERATOR ASSY AND START THE FLOW OF 

OXYGEN THAT CANNOT BE STOPPED.

CAUTION: REFER TO THE UNIT PART NUMBER THAT TELLS YOU 

EITHER THE UNIT IS LEFT HAND OR RIGHT HAND. LEFTHAND UNITS HAVE THE STARTER SIDE (RELEASE PIN) OF 

THE OXYGEN GENERATOR LOCATED ON THE LEFT-HAND 

SIDE OF THE CONTAINER.

(a) Put the oxygen generator between the arms of the generator mounting 

clamp into the container assembly. Make sure the HOT label shows face 

up (See Figure 29). Make sure the orientation of the container is correct.

Figure 29

(b) Turn the generator mounting clamps so that the clamp screws (after

tigthening) are covered by the insulation shield (approx. mid of the oxygen 

generator) (See Figure 30)

(c) Attach the oxygen generator with the generator mounting clamps. Use an 

applicable torque wrench and tighten the clamp screws to a torque value 

of 1,0 Nm (0.4426 ft./lbf).

(d) Install each green generator release lanyard (30) with its metal ring on the 

generator release pin (20)as shown on Figure 31. Do not connect the 

other side of the green generator release lanyard (30) to the mask 

assemblies (47) at this stage.

NOTE: Put the metallic ring of one green generator release lanyard 

(30) in the eyelet of the release pin (13) as shown on Figure.31

(e) Loosen the adjustment screw of the bridle assy (100).

(f) Push the oxygen generator (10) down against the bottom of the container 

assy (140) and hold it tightly in position.

(g) Move the wire loop of the bridle assy (100) over the generator release 

plate (70) and through the hole in the generator release plate (70) as 

shown on Figure 31.

(h) Put the generator release pin (20) together with the green generator 

release lanyards (30) through the wire loop of the bridle assy (100) to hold 

the oxygen generator (10) in position. Fully push the generator release pin 

(20) into the wire loop and turn it to the side (See Figure 31).

(i) Tighten the adjustment screw of the bridle assy (100) to a torque value of 

0.2 Nm +/-0.05 Nm (1.77 in.lbf +/-0.044 in.lbf). This keeps the oxygen 

generator tightly on the bottom of the container.

(a) Restore the masks in the oxygen container assembly as shown on the 

mask installation instruction label in the inside of the container door.

CAUTION: EXERCISE CAUTION WITH THE MASK LANYARDS AND THE 

GENERATOR RELEASE LANYARD WHEN YOU CONNECT 

THEM TO THE SNAP HOOKS OF THE MASKS. AN 

ACCIDENTAL PULL CAN REMOVE THE RELEASE PIN FROM 

THE OXYGEN GENERATOR ASSY AND START THE FLOW OF 

OXYGEN THAT CANNOT BE STOPPED.

(b) Use the pointed pliers to connect the white mask lanyards and the green 

generator release lanyards to the snap hooks of the masks. Make sure 

you connect only one lanyard of each color to a snap hook (See Figure 

32).

(e) Let the flag of the warning flag assy go out of the container at the starter 

side of the generator. Make sure that no lanyards or supply tubes lay on 

the warning flag.

CAUTION: MAKE SURE THAT NO ITEMS ARE BETWEEN THE DOOR 

AND THE CONTAINER BEFORE YOU CLOSE THE DOOR. 

DO NOT APPLY UNCONTROLLED FORCE WHEN YOU CLOSE 

THE DOOR. YOU CAN CAUSE DAMAGE TO THE DOOR. A 

DEFECTIVE DOOR MAKES THE CONTAINER 

UNSERVICEABLE.

(i) Push tightly and equally on both sides of the door until it locks at both 

latch hooks.

(j) Push the right hand side to set test button into the test position.

(k) Turn the container upside down as shown on Figure 34.

(l) Put the manual release tool PNR E60100-00 into the release access hole 

of the door. Unlock the door latch with a slight push. The door must open 

a few degrees and stops at the test position (held by the hook of the test 

button).
