WARNING: MAKE SURE THAT THERE ARE NO PERSONS OR EQUIPMENT NEAR THE RAM AIR OUTLET FLAPS. MOVEMENT OF THE RAM AIR OUTLET FLAPS AND HOT EXHAUST GASES CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.
CAUTION: MAKE SURE THAT THE AREA NEAR THE RAM AIR INLET IS CLEAN AND FREE FROM LOOSE ARTICLES. LOOSE ARTICLES CAN GO INTO THE RAM AIR INLET AND CAUSE DAMAGE TO EQUIPMENT.
B. Stage 2 Cleaning of the ECS
NOTE: You can use the engine bleed or the APU bleed or the HP ground air-supply to do this procedure. Airbus recommends that you use the engine bleed.
NOTE: It is possible that you can get smoke and/or fumes when you do this procedure. Airbus recommends you to open one or more of the passenger/crew doors if possible. This will supply fresh air to the cabin and the cockpit.

   (1) Do one of the steps that follow to start the bleed air supply:
     (a) Start engine 1(2) and keep the engine RPM to idle (Ref. AMM TASK 71-00-00-710-043).
     (b) Start the APU (Ref. AMM TASK 49-00-00-860-005) or (Ref. AMM TASK 49-00-00-860-008).
     (c) Start the HP ground air-supply (Ref. AMM TASK 36-12-00-860-002).
   (2) On AIR COND panel 30VU:
     (a) Make sure that:
  • The X BLEED selector is kept in position as given in the X BLEED selector table
  • The APU BLEED pushbutton switch is pushed (the ON legend is on) if you use the APU bleed
  • The PACK 1 pushbutton switch is pushed (the FAULT and the OFF legends are off) if the source of contamination is engine 1
  • The PACK 2 pushbutton switch is pushed (the FAULT and the OFF legends are off) if the source of contamination is engine 2

     (d) On the lower ECAM DU, make sure that the duct inlet temperature is not more than 70 DEG.C (158 DEG.F) MAX.
     (e) If one of the temperatures go above MAX you must stop the procedure and do the troubleshooting of the ECS (refer to TSM, chapter 21).
   (6) If you use the engine bleed:
     (a) Move the applicable throttle control lever to the idle position.
   (7) On AIR COND panel 30VU:
     (a) Push the HOT AIR pushbutton to the off position (the OFF legend comes on).

   (8) If you use the engine bleed:
     (a) Move the applicable throttle control lever forward until the upper ECAM DU shows N1 between 35 and 40 percent (immediately before HPV closure):
       1 On the lower ECAM DU, the BLEED page shows:
  • PRV ENG 1(2) as in-line and green
  • HPV ENG 1(2) as in-line and green
  • ENG 1(2) pressure: 36 -4 psi or +4 psi (2.4821 -0.2758 bar or +0.2758 bar)

WARNING: MAKE SURE THAT THERE ARE NO PERSONS OR EQUIPMENT NEAR THE RAM AIR OUTLET FLAPS. MOVEMENT OF THE RAM AIR OUTLET FLAPS AND HOT EXHAUST GASES CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.
CAUTION: MAKE SURE THAT THE AREA NEAR THE RAM AIR INLET IS CLEAN AND FREE FROM LOOSE ARTICLES. LOOSE ARTICLES CAN GO INTO THE RAM AIR INLET AND CAUSE DAMAGE TO EQUIPMENT.
B. Stage 2 Cleaning of the ECS
NOTE: You can use the engine bleed or the APU bleed or the HP ground air-supply to do this procedure. Airbus recommends that you use the engine bleed.
NOTE: It is possible that you can get smoke and/or fumes when you do this procedure. Airbus recommends you to open one or more of the passenger/crew doors if possible. This will supply fresh air to the cabin and the cockpit.

   (1) Do one of the steps that follow to start the bleed air supply:
     (a) Start engine 1(2) and keep the engine RPM to idle (Ref. AMM TASK 71-00-00-860-823).
     (b) Start the APU (Ref. AMM TASK 49-00-00-860-005) or (Ref. AMM TASK 49-00-00-860-008).
     (c) Start the HP ground air-supply (Ref. AMM TASK 36-12-00-860-803).
   (2) On CARGO HEAT panel 22VU, push the HOT AIR pushbutton switch to the OFF position (the OFF legend comes on).
   (3) On AIR COND panel 30VU:
