C. 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 anti-ice valve sense line connections at the anti-ice valve (7), the air cycle machine (2) and the condensor (7).
(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 anti-ice valve sense line connections at the anti-ice valve (7), the air cycle machine (2) and the condensor (7).
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).
