(6)
On the P1 pitot−static test adaptor, connect the static hose assembly to the S2 static port.
(7)
On the P2 pitot−static test adaptor, connect the static hose assembly to the S1 static port.
(8)
Connect the other end of the static hose assembly to the pitot−static pressure output line of
the air test panel.
(9)
Connect the dry compressed air source to the air test panel.
(10) Start an airflow at 20 psi (137.90 kPa) into the P1 static port S2 and P2 static port S1.
(11) Connect the purging hose on the openings that follow and make sure that there is an
airflow:
– Static connector for the ADC 2
– S2/S1 drain assembly on the ADC 2 static line
– S2/S1 drain assembly on the static manifold.
(12) Disconnect the purging hose.
(13) Decrease the airflow to the static ports to 0 psi (0 kPa).
(14) Remove the pitot−static test adaptors from the P1 and P2 pitot−static heads.
NOTE:
Make sure that there is no fluid or other contamination on the pitot−static head.
(15) Install the drain collector tubes on the static line drains that follow:
– S2/S1 drain assembly on the ADC 2 static line
– S2/S1 drain assembly on the static manifold.
(16) Remove the cap from the static connector on the ADC 2.
(17) Connect the static connector to the ADC 2.
(18) Disconnect the dry compressed air source from the air test panel.
(19) Disconnect the pitot−static test adaptor from the pressure output line of the air test panel.
