 A. Job Set-up
 (1) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
 (2) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001). 
R  B. Test 
R R R R R R  (1) Start the APU: - GTCP 36-300 (Ref. AMM TASK 49-00-00-860-003) or - APS 3200 (Ref. AMM TASK 49-00-00-860-005) or - 131-9(A) (Ref. AMM TASK 49-00-00-860-008).

R R R (2) On the AIR COND panel 30VU, push the APU BLEED pushbutton switch (5HV) (the ON legend comes on). 
4. Fault Isolation_______________
 A. On the upper ECAM DU, if the AIR L WING LEAK warning comes into view: - do a leak test on the bleed air ducts (Ref. AMM TASK 36-22-00-790-001).
 (1) If there are leaks: - replace the defective ducts or seals as necessary.
 (2) If there is no leak: - do a hot-air leak check in the air conditioning bay (Ref. AMM TASK 21-52-00-200-010).
 (a) If there are cracks or damage on the ducts: - replace the defective ducts.
 (b) If there are leaks on the seals: - replace the defective seals.
 5. Close-up________ 
R  A. Put the aircraft back to its initial configuration. 
R R  (1) On the AIR COND panel 30VU, release the APU BLEED pushbutton switch (5HV) (the ON legend goes off).
