4. Procedure
Subtask 21-61-19-420-050-A ** ON A/C NOT FOR ALL
A. Installation of the Pack-Outlet Pneumatic Sensor
   (1) Make sure that the parts retained from the removed component are clean and in the correct condition.
   (2) Make sure that the removed packing (5) is in a good condition. If necessary replace the AIPC 21-52-41-26-100 PACKING (5).
   (3) Remove the blanking plugs from the disconnected line ends.
   (4) Clean the component interfaces and the adjacent area.
   (5) Apply a small quantity of Mineral Oil base Grease-- Vaseline or Petrolatum - (Material No.03FAB1) to the screws (1).
   (6) Put the packing (5) in position on the pack-outlet pneumatic sensor (4).
   (7) Put the pack-outlet pneumatic sensor (4) in position in the condensor (6) and install the washers (2) and the screws (1).
   (8) Make sure that the pack-outlet pneumatic sensor (4) is in the correct position and tighten the screws (1).
   (9) Wipe clean the excess Mineral Oil base Grease-- Vaseline or Petrolatum - (Material No.03FAB1) from the screws (1) and safety with 14QDB1Wire-Locking Dia: 0.5 mm (0.020 inch) CRES Nickel Alloy -.
   (10) Connect the sense line (3).
   (11) TORQUE the sense line (3) connector to between 0.915 and 0.9 m.daN (80.97 and 79.65 lbf.in ) T.

C. Test
   (1) Do the pre-conditioning through the HP ground connector or with the APU (Ref. AMM TASK 12-33-21-618-001) (Ref. AMM TASK 12-33-21-618-001).
   (2) Do a leak check of the pack-outlet pneumatic sensor sense line connection.
NOTE: Leaks are not permitted.
   (3) After approx. 15 minutes stop the pre-conditioning (Ref. AMM TASK 12-33-21-618-001) (Ref. AMM TASK 12-33-21-618-001).
   (4) Do the operational test of the pack temperature control system (Ref. AMM TASK 21-61-00-710-001).
5. Close-up
