B. Preparation for the Functional Test

CAUTION: BE CAREFUL WHEN YOU CONNECT/DISCONNECT THE TEST SET TO/FROM THE EQUIPMENT. THE PRESSURE REGULATING VALVE AND THE PRESSURE GAGE ASSEMBLY OF THE TEST SET ARE HEAVY AND CAN CAUSE DAMAGE TO THE ENGINE.

(1) Disconnect the sense line of the FAV.
(2) Put the blanking plug on the disconnected end of the sense line.
(3) Connect manually the 98D36109001000 TEST SET-EBAS,BLEED to the sense line port of the FAV.
(4) Close the shutoff valve, the purge valve and the pressure regulator valve on the 98D36109001000 TEST SET-EBAS,BLEED.

NOTE: If the air cylinder has a regulator valve, it is not necessary to install the primary regulator valve supplied with the test set.

(5) Connect the AIR SOURCE 3 BAR (43.5 PSI) - REGULATED, FILTERED, DRY to the 98D36109001000 TEST SET-EBAS,BLEED.
(6) Set the digital pressure gage to zero.

Functional Test of the Opening of the Fan Air Valve 9HA1 with the Bleed Test Set P/N 98D36109001000 ** ON A/C NOT FOR ALL

(1) Do this test:

ACTION	RESULT
1.On the AIR SOURCE 3 BAR (43.5 PSI) - REGULATED, FILTERED, DRY: Open the shut off valve.	On the AIR SOURCE 3 BAR (43.5 PSI) - REGULATED, FILTERED, DRY: The cylinder pressure gage shows the pressure.
2.On the AIR SOURCE 3 BAR (43.5 PSI) - REGULATED, FILTERED, DRY: Use the primary regulator to pressurize to 20 psi (1.4 bar).	On the AIR SOURCE 6.9 BAR (100 PSI) - REGULATED,FILTERED, DRY: The primary gage shows 20 psi (1.4 bar).
3.On the 98D36109001000 TEST SET-EBAS,BLEED: Slowly pressurize the system to get a pressure value of 15 psi (1.03 bar).	On the 98D36109001000 TEST SET-EBAS,BLEED: The digital pressure gage shows the pressure. On the Fan Air Valve rod (2): Verify the correct position of the rod in OPEN position. NOTE: The FAV butterfly is in the OPEN position when the actuator is fully extended and the lever locking hole is not aligned with the locking hole of the FAV body. On the Fan Air Valve body: Verify the visual position indicator. Open time must be less than 4 seconds.
4.On the 98D36109001000 TEST SET-EBAS,BLEED: Depressurize the system.	On the 98D36109001000 TEST SET-EBAS,BLEED: The digital pressure gage shows 0 psi (0.00 bar). On the Fan Air Valve rod: Verify the correct position of the rod. NOTE: The FAV butterfly is in CLOSE position when the locking hole of the lever and the locking hole of the FAV body is aligned and the locking pin can be installed. On the Fan Air Valve body: Verify the visual position indicator. Close time must be less than 4 seconds.
5.Depressurize the AIR SOURCE 3 BAR (43.5 PSI) - REGULATED, FILTERED, DRY and close the shut off valve.
