Installation of the Compressor Overheat - Temperature Sensor
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 compressor overheat temperature sensors 15HH and 35HH.
