Removal of the Water-Extractor Temperature Sensors

TASK 21-61-13-000-001-A
Removal of the Water-Extractor Temperature Sensors

WARNING: MAKE SURE THAT AIR IS NOT SUPPLIED TO THE AIR CONDITIONING SYSTEM FROM THE MAIN ENGINE, THE APU OR A GROUND SOURCE. HOT COMPRESSED AIR CAN CAUSE INJURY TO PERSONNEL.
NOTE: The procedure is the same for the water-extractor temperature sensors 11HH and 31HH. The water-extractor temperature sensors are installed in the reheaters.
