A. Installation of the Solenoid Valve
(1) Put the solenoid valve (5) in position and install the screw (4), the washer (6), and the nut (7).
(2) Remove the blanking plugs from the disconnected line ends.
(3) Apply a small quantity of Lubricant-Anti Seize High Temp. - (Material No.03PBB1) to the threaded parts of the connectors (2) and (3).
(4) At the solenoid valve (5), install the sense line connectors (2) and (3).
(5) TORQUE the sense line connectors (2) and (3) to between 0.915 and 0.9 m.daN (80.97 and 79.65 lbf.in ).
(6) Remove the blanking caps and connect the electrical connector (1).

. (6) Remove the blanking caps and connect the electrical connector (1).
B. Leak and Operational Test of the Sense Lines Assembly
(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 sense line connectors (2) and (3) at the solenoid valve (5).
(4) Do the operational test of the pack temperature control system (Ref. AMM TASK 21-61-00-710-001).
5. Close-up(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 sense line connectors (2) and (3) at the solenoid valve (5).
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).
