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 the adaptor assembly to the sense-line test port on the FAV.
(4) Tighten the adaptor assembly.
(5) Connect the short hose to the adaptor assembly.
(6) 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.

(7) Connect the AIR SOURCE 3 BAR (43.5 PSI) - REGULATED, FILTERED, DRY to the 98D36109001000 TEST SET-EBAS,BLEED.

ACTION	RESULT
1.On the AIR SOURCE 3 BAR (43.5 PSI) - REGULATED, FILTERED, DRY: Open the shutoff 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 3 BAR (43.5 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 15 +1 psi or -1 psi (1.03 +0.07 bar or -0.07 bar).	On the 98D36109001000 TEST SET-EBAS,BLEED: The digital pressure gage shows 15 +1 psi or -1 psi (1.03 +0.07 bar or -0.07 bar).
