C. Aircraft Maintenance Configuration

WARNING: MAKE SURE THAT THE FWD AVIONICS ACCESS DOOR 811 IS OPEN WITH A WARNING PLACARD ATTACHED TO IT. THE WARNING NOTICE MUST TELL PERSONS NOT TO CLOSE THE DOOR. THIS PREVENTS ACCIDENTAL PRESSURIZATION OF THE AIRCRAFT.

(1) Pre-condition the Aircraft

do the pre-conditioning with the APU (Ref. AMM TASK 12-33-21-618-001) or through the HP ground connector (Ref. AMM TASK 12-33-21-618-001) .

(2) On the AIR COND panel 30VU make sure that:
(a) the PACK FLOW selector is in the NORM position and,
(b) the PACK 1 and the PACK 2 pushbutton switches are in the on position (the OFF legend is off).
(3) Do the EIS start procedure (upper ECAM DU and lower ECAM DU only)
(Ref. AMM TASK 31-60-00-860-001).

WARNING: MAKE SURE THAT THERE ARE NO PERSONS OR EQUIPMENT NEAR THE RAM AIR OUTLETS. HOT EXHAUST GASES CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.

A. Functional Test of the Temperature Control System

System Display Pages - Component Location

NOTE: Make sure that the cabin doors and the cockpit windows are closed when you do the test.

NOTE: Due to low pressure in the trim system, with fully closed trim air valves the trim-air pressure regulating-valve symbol (6) can be indicated as closed and show amber.
You must ignore this indication for the purposes of this test.

ACTION	RESULT
1.On the ECAM control panel: push the BLEED pushbutton switch.	On the System Display (SD): the BLEED page comes on, the pack flow-control valves symbols (1) move to the open positions and show green.
2.On the AIR COND panel 30VU: put the COCKPIT, the FWD CABIN and the AFT CABIN temperature selectors to the mid (12 o'clock) position ( 24 deg.C (75.20 deg.F)).
3.On the ECAM control panel: push the COND pushbutton switch.	On the SD: the COND page comes on.
4.Wait until the CKPT, the FWD and the AFT zone temperatures (5) have stabilized at 24 deg.C (75.20 deg.F).	On the SD (COND page): the CKPT, the FWD and the AFT zone temperatures (5) are shown in green.
5.On the AIR COND panel 30VU: put the COCKPIT, the FWD CABIN and the AFT CABIN temperature selectors to the HOT position ( 30 deg.C (86.00 deg.F)).	On the SD (COND page): the trim-air pressure regulating-valves symbols (6) show green and open. the CKPT, the FWD and the AFT zone temperatures (5) start to increase. the trim-air valves position needles (4) show green and open to a maximum of 80%, then start to close, if the target temperature is reached, or if the duct temperature limits are reached.
6.On the ECAM control panel: push the BLEED pushbutton switch.	On the SD: the BLEED page comes on, the temperature control valves position needles (2) show green and move to the open (H) positions, the pack outlet temperatures (3) show a maximum of 70 deg.C (158.00 deg.F).
7.On the AIR COND panel 30VU: put the COCKPIT, the FWD CABIN and the AFT CABIN temperature selectors to the COLD position ( 18 deg.C (64.40 deg.F)) and wait for apprx. 3 minutes.	On the SD (BLEED page): the temperature control valves position needles (2) show green and move to the closed (C) positions, the pack outlet temperatures (3) decrease, (the lowest pack outlet temperatures reached are dependant upon the outside air temperature).
8.On the ECAM control panel: push the COND pushbutton switch.	On the SD: the COND page comes on, If the actual temperature is more than the selected temperature, or the duct temperatures are more than the allowed lower duct temperatures then, the trim air valves position needles (4) show green and move to the closed (C) positions, the CKPT, the FWD and the AFT zone temperatures (5) decrease.

A. Aircraft Maintenance Configuration
(1) On the AIR COND panel 30VU put the cockpit and the cabin TEMP selectors to the 12 o'clock position.
(2) Push the PACK 1 and the PACK 2 pushbutton switches to the off position (the OFF legends are on).
(3) Do the EIS stop procedure
(Ref. AMM TASK 31-60-00-860-002).
(4) Stop the pre-conditioning with the APU (Ref. AMM TASK 12-33-21-618-001) or through the HP ground connector (Ref. AMM TASK 12-33-21-618-001) .
