D. Preconditioning
(1) Do the Procedure to Start the APU: or

(2) Do the preconditioning through the HP connector (Ref. AMM TASK 12-33-21-618-001), or
(3) Do the preconditioning with engine bleed.

Start the engine 1(2) (Ref. AMM TASK 71-00-00-710-043) or (Ref. AMM D/O 71-00-00-86).
Make sure that the X BLEED selector is at the AUTO position on the AIR COND panel 30VU.
Make sure that the PACK 1 and the PACK 2 pushbutton switches are in the on position (the FAULT and the OFF legends are off).
Move the applicable throttle control lever forward until on the BLEED page a pack inlet pressure of 30 psig is shown.

NOTE: Use this alternative procedure if during the test the pack flow indicator does not reach the predetermined position.

E. Aircraft Maintenance Configuration
(1) Do the EIS start procedure (Ref. AMM TASK 31-60-00-860-001).
(2) On the AIR panel 30VU:

put the APU BLEED pushbutton switch to the on position (the ON legend comes on) and,
put the PACK 1 and the PACK 2 pushbutton switches to the on position (the OFF legends go off).

(3) Make sure that the BLEED page is shown on the ECAM lower display.
(4) Cockpit Effects
(a) After approximately 60 seconds:

on the COND page the message ALTN MODE shows above the aircraft symbols and,
on the upper ECAM display the message, COND ZONE REGUL FAULT, is shown.
