B. CONCURRENT REQUIREMENTS
For 1XC15-0100-Series Oxygen Container - Not Applicable
For all 1CX22-0100-Series Oxygen Container

This SB requires the simultaneously ac complishment of the Service Bulletin No. 1XC22_0100-35-006.

C. REASON

During manufacturing at the manufacturer facilities partic les 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 . Green Dot

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) Open the Door Assy as follows:

CAUTION : EXERCISE CAUTION WITH THE MASK LANYARDS WHEN YOU OPEN THE DOOR ASSY, AN ACCIDENTAL PULL CAN REMOVE THE RELEASE PIN FROM THE OXYGEN GENERATOR ASSY AND START THE FLOW OF OXYGEN THAT CANNOT BE STOPPED.

(a) Set the test button into the test position.

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 Outlet port O-ring E20274-06

(c) Put the manifold together with the mask hoses on the Mask Hose Assembly Tool PNR. 2231070 .

(d) Fully move the masks with the Mask Hose Assembly Tool PNR. 2231070 on the fittings of the manifold as shown on Figures 22 and 23. Then remove the manifold from the Assembly Tool.

(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. (See Figures 4 and 27). Cable Tie Pliers

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.

# SB 1XCXX-0100-35-005 (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 YOUEITHER 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 br idle 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. Insulation Shield Torque Wrench with hexagon spanner head (1⁄4 in.)

(3) Final Assembly

(a) Restore the masks in the oxygen container assembly as shown on the mask installation instru ction 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).

(c) Remove the rubber bands from the masks.
(d) Look at the unit before you close the door (See Figure 33). Make sure that:

- all rubber bands are removed from the masks, - all parts are assembled and properly oriented, - that none of the masks elastic head bands, oxygen supply tubes, nor lanyards will be closed in the door, - the eyelet of the release pin shows face upward, - the generator release pin has been turned in parallel to the oxygen generator.

# SB 1XCXX-0100-35-005 (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 te st 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).
