 A. Draining and Flushing of the Standby Static and the Standby Total Pressure Lines
 (1) Blow the gas into each of the instrument hoses (5) and into the hose (7), from one to the other, at a pressure of 2 bars (29 psi). Do this for approximately 5 minutes.
 (2) Put the pneumatic cleaner pitot adapter on the draining hole of the pitot probe 3 and blow the gas for approximately 30 seconds.

 (3)
 Make sure that there is no contamination in the pressurized gas at these outlets:

 -L static probe 3 and R static probe 3
 -Pitot probe 3
 -Water drain
 -Pipe of the cabin-pressure detection pressure-switch.

 (4)
 Put an ADAPTER COVER-STATIC PORT on the L static probe 3 then on the R static probe 3.

 (5)
 Make sure that the flow of gas is correct at :

 -
the pipe of the pressure switch

 -
the water drain.

 (6)
 Stop the flow of gas.
