- 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.

- on the upper ECAM DU if the pack 2 flow shows in the HI flow position and both pack flow-control valve indications show green,
- replace the VALVE-FLOW CTL (8HB) (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 2 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 21-51/01) from:
- the FCV (8HB/A) pin C to the PACK1 TEMP CONTROLLER (7HH/AA) pin 7B.
(b) If the fault continues:
- replace the P2 FLOW CTL VALVE (8HB) (Ref. AMM TASK 21-51-51-000-001) and (Ref. AMM TASK 21-51-51-400-001).
