 H. Test
 (1) Do the pre-conditioning through the HP ground connector (Ref. TASK 12-33-21-618-001) or with the APU (Ref. TASK 12-33-21-618-001).
 (2) Do a leak check of the air conditioning pack.
 NOTE : Minimum leakage is permitted. After the pack operates some____ minutes, the leakage of air will reduce because the seals have their correct operating temperature.
 (3) Do a leak check of the sense line connections.
 NOTE : Leaks are not permitted.____
 (4) After aprx. 15 minutes stop the pre-conditioning (Ref. TASK 12-33-21-618-001) or (Ref. TASK 12-33-21-618-001).
 (5) Do the operational test of the cockpit and cabin temperature control (Ref. TASK 21-63-00-710-004).
