(4) If the fault continues:

 - replace the CONTROLLER-PACK 2 TEMP (27HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).

 (5) If the fault continues:

 - do a check of the position of the manual override lever of the pack 2 anti-ice valve (37HH).
 (a) If the valve is not closed:
 - disconnect the electrical connector (37HHA) (Ref. AMM TASK 21-61-41-000-001).

 - do a check for 28 VDC at the electrical connector (37HHA) between pins A and B (Ref. ASM 21-61/02).

 1 If the voltage is correct:
_
 - replace the SENSOR-PACK OUTLET PNEUMATIC (11HM10) (Ref. AMM TASK 21-61-19-000-001) and (Ref. AMM TASK 21-61-19-400-002).
 2 If the fault continues:
_
 - replace the VALVE-ANTI-ICE (37HH) (Ref. AMM TASK 21-61-41-000-001) and (Ref. AMM TASK 21-61-41-400-001).
 3 If the voltage is not correct:
_
 - do a check of the wiring (Ref. ASM 21-61/02) from:

 - the VALVE (37HH) to the PC 2 (27HH) and,

 - the VALVE (37HH) to ground.

 (6) If the fault continues:
 (a) Do a check of the reheater (11HM3) for contamination (Ref. AMM TASK 21-52-00-780-001).
 NOTE : This sub-paragraph (7) is only applicable to reheaters
____ with the P/N 755A0000-04 and previous. It is not applicable to reheaters with the P/NIs 755A0000-04 Amendment A or subsequent.
 (b) If the reheater is clogged:
 - do the cleaning of the clogged reheater (11HM3) (Ref. AMM TASK 21-52-00-100-002),
 (7) If the fault continues:

 - do the cleaning of the clogged condenser (11HM2) (Ref. AMM TASK 21-52-00-100-003),

 (8) If the fault continues:

 - do a check of the position of the manual override lever of the pack 2 flow control-valve (8HB).
 (a) If the valve is not fully open:
 - replace the VALVE-FLOW CTL (8HB) (Ref. AMM TASK 21-51-51-000-001) and (Ref. AMM TASK 21-51-51-400-001).

 Aug 01/05 CES (9) If the fault continues:

 - do a check of the water drain line between the extractor (11HM8) and the injector (21HM) and the injector nozzle (21HM) for contamination and clean it if necessary (Ref. AMM TASK 21-52-16-000-001), (Ref. AMM TASK 21-52-16-400-001), (Ref. AMM TASK 21-52-42-000-001) and (Ref. AMM TASK 21-52-42-400-001).
R **ON A/C 401-499,

R D. If the PDT 2 is above 10 Deg.C with the selectors COCKPIT, FWD CABIN and
R AFT CABIN, which are installed on the panel 30VU, set to COLD:
R - open and close the CBs 1HK, 2HK, 3HK and 4HK.

R (1) If the PDT 2 goes below 10 Deg.C:
R - do the functional test of the cockpit and cabin temperature control
R system (Ref. AMM TASK 21-63-00-720-001).

R (2) If the fault continues:

R (a) Remove the inspection panel from the pack 2 ram-air inlet plenum
R (11HM14).

R (b) Do a check of the water injector nozzle for damage or wear:
R - replace the water injector nozzle if it is worn or damaged
R (Ref. AMM TASK 21-52-00-960-001).

R (c) Do a check of the main heat exchanger (11HM7) for contamination:
R - if the main heat exchanger is clogged do the cleaning of the
R clogged main heat exchanger (11HM7) and the clogged primary
R heat exchanger (11HM6) (Ref. AMM TASK 21-52-00-100-001).

R (d) Install the inspection panel on the pack 2 ram-air inlet plenum
R (11HM14).

R (3) If the fault continues:
R - do a check that the resistance of the water extractor temperature
R sensor (31HH) measured between connector A/E and A/F and connector
R A/C and A/D is in these limits (Ref. ASM 21-61/02):
R Temp (Deg.C) OHMS
R ---------------------------R + 10 18820 +/- 5 %
R + 18 13340 +/- 5 %
R + 25 10000 +/- 5 %
R + 30 8197 +/- 5 %
R + 40 5598 +/- 5 %
R + 50 3903 +/- 5 %

R (a) If the resistance values are out of the specified limits:
R - replace the SENSOR-WATER EXTRACTOR TEMPERATURE (31HH) (Ref. AMM
R TASK 21-61-13-000-001) and (Ref. AMM TASK 21-61-13-400-001).
