- make sure that the pack 1 inlet pressure indication shows a minimum of 24 PSI.
NOTE : If the indication shows less than 24 PSI you must:
____
- increase the ground pressure supply until the indication shows a minimum of 24 PSI.
B. Start the engines (Ref. AMM TASK 71-00-00-710-003) if necessary.

A. This procedure is only applicable for the Flow Control Valves P/N 751 series.
(1) When the pack flow selector is at the LO or NORM position:
- on the upper ECAM DU if the pack 1 flow shows in the HI flow position and both pack flow-control valve indications show green,
- replace the VALVE-FLOW CTL (11HB) (Ref. AMM TASK 21-51-51-000-001) and (Ref. AMM TASK 21-51-51-400-001).

(1) When the pack flow selector is at the LO or NORM position:
- on the upper ECAM DU if the pack 1 flow shows in the HI flow position and both pack flow-control valve indications show green,
(a) do a check of the wiring (Ref. ASM 21-51/01) and (Ref. ASM 21-51/02) from:
- the FCV (11HB/A) pin C to the PACK2 TEMP CONTROLLER (27HH/AA) pin 7B.
(b) If the fault continues:
- replace the VALVE-FLOW CTL (11HB) (Ref. AMM TASK 21-51-51-000-001) and (Ref. AMM TASK 21-51-51-400-001).

A. Bleed Air Supply Source from the HP Ground Connection
NOTE : The HP ground supply source must be able to give a pack inlet
____ pressure of 24 PSI minimum. If it can not do this then you must get the bleed air supply from the engines. The work steps which follow show the conditions necessary before you get the minimum pack-inlet pressure.
(1) Do the pre-conditioning through the HP ground connection (Ref. AMM TASK 12-33-21-618-001).
(2) On the AIR COND panel 30VU:
- push the HOT AIR pushbutton switch to the on position (the OFF legend goes off),
- turn the COCKPIT, FWD CABIN and the AFT CABIN temperature selectors to the HOT positions and,
- make sure that the PACK 1 and the PACK 2 pushbutton switches are in the on position (the OFF legends are off). 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 AIR CONDITIONING 空调2(6)
