AK. Inspection of the ECS for Contamination

WARNING: MAKE SURE THAT AIR IS NOT SUPPLIED TO THE AIR CONDITIONING SYSTEM FROM THE MAIN ENGINE, THE APU OR A GROUND SOURCE. HOT COMPRESSED AIR CAN CAUSE INJURY TO PERSONNEL.

WARNING: DO NOT TOUCH THE COMPONENT UNTIL IT IS SUFFICIENTLY COOL TO PREVENT BURNS.

(1) Do a check by hand for the oil contamination in condensers 10HM2 and 11HM2.
(2) If there is no oil contamination in the condensers then continue with the preparation for and stage 2 cleaning of the ECS.
(3) If you find the oil contamination in the condensers then you must:

Clean the components in the system as necessary (Ref. AMM TASK 21-00-00-100-001),
Continue with the preparation for and stage 2 cleaning of the ECS.

(4) If you find large deposits of oil contamination in the condensers then you must overhaul or replace the air cycle machine:
(a) To do an overhaul:
1 Remove the air cycle machine (Ref. AMM TASK 21-52-21-000-001).
2 Send the air cycle machine to the workshop for an overhaul.
3 Install the air cycle machine (Ref. AMM TASK 21-52-21-400-001), or
(b) To replace the air cycle machine (Ref. AMM TASK 21-52-21-000-001) and (Ref. AMM TASK 21-52-21-400-001).

AL. Preparation for Stage 2 Cleaning of the ECS
(1) Do one of the steps that follow to install the clamps and the sleeves between the condenser(s) and the check valve(s):
(a) If the source of contamination is engine 1:
1 Remove the clamps from the special blanking cap.
2 Remove the special blanking cap from check valve 15HM.
3 Install the clamps and the sleeve between condenser 10HM2 and check valve 15HM (Ref. AMM TASK 21-52-43-400-001) and (Ref. AMM TASK 21-52-32-400-001).
(b) If the source of contamination is engine 2:
1 Remove the clamps from the special blanking cap.
2 Remove the special blanking cap from check valve 16HM duct flange.
3 Install the clamps and the sleeve between condenser 11HM2 and check valve 16HM duct flange (Ref. AMM TASK 21-52-43-400-001) and (Ref. AMM TASK 21-52-32-400-001).
(c) If the source of contamination is APU or unknown:
1 Remove the clamps from the special blanking caps.
2 Remove the special blanking caps from check valve 15HM and from check valve 16HM duct flange.
3 Install the clamps and the sleeve between condenser 10HM2 and check valve 15HM (Ref. AMM TASK 21-52-32-400-001) and (Ref. AMM TASK 21-52-43-400-001).

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.

AN. 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.

AN. 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.
