4. Procedure
Subtask 36-12-00-710-055-A

A. Operational Test of the Crossbleed Valve in the Manual Mode

ACTION	RESULT
1.On the ECAM control panel 11VU:	On the ECAM control panel 11VU:
push the BLEED pushbutton switch.	the light in the BLEED pushbutton switch comes on (white).
	On the lower ECAM display unit: the BLEED page comes into view
2.On the AIR COND overhead control panel 30VU:	On the crossbleed valve 6HV:
set the X-BLEED selector switch to the SHUT position.	the manual override lever and position indicator is in the 'C' (close) position.
	On the BLEED page of the lower ECAM display unit: the crossbleed valve symbol is in the crossline (green) position.
3.On the AIR COND overhead control panel 30VU:	On the crossbleed valve 6HV:
put the X-BLEED selector switch in the OPEN position.	the manual override lever and position indicator moves from the 'C' to the 'O' position.
	On the BLEED page of the lower ECAM display unit: after approximatly 5 seconds the crossbleed valve symbol changes from the cross line (green) to in line (green) NOTE: The crossbleed valve symbol is amber during movement of the crossbleed valve.

A. Put the aircraft back to the serviceable condition.
(1) On the AIR COND overhead control panel 30VU turn the X-BLEED selector switch in the AUTO position.
(2) Do the EIS stop procedure
(Ref. AMM TASK 31-60-00-860-002).
(3) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
