   (2) Remove the protective covers from the open ends of the flange (23), the pack flow-control valve (29) and the ozone filter (30).
   (3) Clean the component interfaces and the adjacent area.
   (4) Make sure that the parts retained from the removed component are clean and in the correct condition.
   (5) Make sure that the O-ring (17) is in a good condition. If necessary, replace the AIPC 21-51-03-11-090 PACKING-PREFORMED (17) or AIPC 21-51-83-07-290 SEAL (17) or AIPC 21-51-03-12-090 PACKING-PREFORMED (17).
   (6) Put the O-ring (17) in position on the ozone filter flange (16).
   (7) Make sure that the bolts (32), the washers (33) and the nuts (34) are loosely assembled with the bracket (12).
   (8) Carefully put the ozone filter (30) in position on the bracket (12) and on the pack flow-control valve (29).
NOTE: You must make sure that you do not move the O-ring (17) when you install the ozone filter (30).
   (9) Install the bolts (24), the washers (25) and the nuts (26).
   (10) Tighten the nuts (26).
   (11) Put the tie-rod (1) in position and install the bolt (15), the washer (14) and the nut (13).
   (12) Tighten the nut (13).
   (13) Install the clamp (22).
   (14) TORQUE the clamp (22) to between 0.930 and 0.810 m.daN (82.30 and 71.68 lbf.in ) T.
   (15) Move the sleeve (11) and the flange (23) in position on the ozone filter (30).
NOTE: Turn the sleeve (11) when you move it.
This will help to prevent damage to the seals in the sleeve (11).
   (16) Install the clamp (31) and make sure that the connecting straps (35) are:
  • Not twisted
  • In a horizontal position
  • Parallel to each other.
   (17) TORQUE the clamp (31) to between 0.500 and 0.400 m.daN (44.25 and 35.40 lbf.in ) T.
   (18) TORQUE the nuts (34) to between 0.8 and 0.7 m.daN (70.80 and 61.95 lbf.in ) T.
   (19) Put the bonding strap (19) in position and install the screw (18), the washer (20) and the nut (21).
   (20) Tighten the nut (21).
   (21) Do the electrical resistance measurement and the final protection of the bonding point(s)
(Ref. AMM TASK 20-28-00-912-802).
