- do the functional test of the cockpit and cabin temperature control system (Ref. AMM TASK 21-63-00-720-001).
(2) If the fault continues:
(a) Remove the inspection panel on the pack 1 ram-air inlet plenum (10HM14).
(b) Do a check of the water injector nozzle for damage or wear:
- replace the water injector nozzle if it is worn or damaged (Ref. AMM TASK 21-52-00-960-001).
(c) Do a check of the main heat exchanger (10HM7) for contamination:
- if the main heat exchanger is clogged do the cleaning of the clogged main heat exchanger (10HM7) and the clogged primary heat exchanger (10HM6) (Ref. AMM TASK 21-52-00-100-001).
(d) Install the inspection panel on the pack 1 ram-air inlet plenum (10HM14).
(3) If the fault continues:
- do a check that the resistance of the water extractor temperature sensor (11HH) measured between connector A/E and A/F and connector A/C and A/D is in these limits (Ref. ASM 21-61/04):
Temp (Deg.C) OHMS ---------------------------
+ 10 18820 +/- 5 %
+ 18 13340 +/- 5 %
+ 25 10000 +/- 5 %
+ 30 8197 +/- 5 %
+ 40 5598 +/- 5 %
+ 50 3903 +/- 5 %
(a) If the resistance values are out of the specified limits:
- replace the SENSOR-WATER EXTRACTOR TEMPERATURE (11HH) (Ref. AMM TASK 21-61-13-000-001) and (Ref. AMM TASK 21-61-13-400-001).

(4) If the fault continues:
- replace the CONTROLLER-PACK 1 TEMP (7HH) (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 1 anti-ice valve (17HH).
(a) If the valve is not closed:
- disconnect the electrical connector (17HHA) (Ref. AMM TASK 21-61-41-000-001).
- do a check for 28 VDC at the electrical connector (17HHA) between pins A and B (Ref. ASM 21-61/04).
1 If the voltage is correct:
_
- replace the SENSOR-PACK OUTLET PNEUMATIC (10HM10) (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 (17HH) (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 and repair the wiring if necessary between: VALVE (17HH) connector A/A and PC 1 (7HH) connector AB/8A, VALVE (17HH) connector A/B and GND, VALVE (17HH) connector A/C and GND (Ref. ASM 21-61/04).
(6) If the fault continues:
- do a check of the reheater (10HM3) 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.
(a) If the reheater is clogged:
- do the cleaning of the clogged reheater (10HM3) (Ref. AMM TASK 21-52-00-100-002),
(7) If the fault continues:
- do the cleaning of the clogged condenser (10HM2) (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 1 flow control-valve (11HB).
(a) If the valve is not fully open:
- replace the VALVE-FLOW CTL (11HB) (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 (10HM8) and the injector (20HM) and the injector nozzle (20HM) 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).
