A. Connection of the Test Set

Functional Test of the Bleed-Pressure Regulator Valve with the Bleed Test Set P/N 98L36103002000 ** ON A/C NOT FOR ALL

(1) Removal of the lockwire:

WARNING: USE PROTECTIVE GOGGLES AND GLOVES WHEN YOU REMOVE OR INSTALL LOCKWIRE. EACH TIME YOU CUT LOCKWIRE, REMOVE AND DISCARD IT IMMEDIATELY. LOOSE LOCKWIRE CAN CUT YOU OR MAKE YOU BLIND, AND/OR CAN CAUSE DAMAGE.

(a) Cut, remove and discard the lockwire from the blanking cap of the test port of the PRV.
(2) Remove the blanking cap from the test port of the PRV.
(3) Connect the M82000460 CLAPPER,BLEED-EXTERNAL to the test port of the bleed-pressure regulator valve.
(4) Close the shutoff valve, the purge valve and the pressure regulator valve on the test set.

WARNING: MAKE SURE THAT THE PRESSURE SUPPLIED TO BLEED TEST SET 98L36103002000 NEVER EXCEEDS 217 PSI (15 BAR). IF THE PRESSURE SUPPLIED TO THE BLEED TEST SET EXCEEDS THIS VALUE, THERE IS A RISK OF INJURY TO PERSONNEL AND DAMAGE TO EQUIPMENT. IF THE AIR CYLINDER DOES NOT HAVE A MANOMETER INSTALLED, YOU MUST INSTALL THE PRIMARY REGULATOR VALVE BETWEEN THE AIR BOTTLE AND BLEED TEST SET 98L36103002000. THE PRIMARY REGULATOR VALVE WILL LIMIT THE PRESSURE IN THE BLEED TEST SET TO 217 PSI (15 BAR).

(5) Connect an air cylinder to the 98L36103002000 TEST SET - ENGINE BLEED.
(6) Connection of the test set.

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.

(a) Connect the 98L36103002000 TEST SET - ENGINE BLEED with the short bend flexible-assembly to the M82000460 CLAPPER,BLEED-EXTERNAL.
(7) Do a reset of the digital pressure gage.
(8) Make sure that the regulator valve of the test set is closed before pressurize the system.

Bleed-Pressure Regulator Valve - Test Set Installation ** ON A/C NOT FOR ALL

(1) On the AIR COND panel 30VU:

Push the ENG 1(2) BLEED pushbutton switch (the OFF legend goes off).

(2) Do this test:

ACTION	RESULT
1.Pressurize the test set: If there is a manometer in the air cylinder then the installation of the primary regulator valve is not necessary. Use the air cylinder shut off valve and the manometer to slowly pressurize the test set to 200 psi (13.7895 bar). If there is no manometer in the air cylinder then the installation of primary regulator valve is mandatory. In this case the primary regulator valve will limit the pressure of the test set to 217 psi (14.9616 bar).
	On the bleed-pressure regulator valve (4001HA): Make sure that the visual position indicator shows that the valve is closed.
2.On the test set: Open the shutoff valve. Use the pressure regulator valve of the test set to slowly pressurize the system to 31 psi (2.1374 bar). NOTE: Read the pressure on the digital pressure gage. NOTE: The pressure value given in this test is applicable to all types of valves. But the opening pressure can change with the reference of the valve.	On the bleed-pressure regulator valve (4001HA): Make sure that the visual position indicator shows that the valve is open.
3.In the cockpit, on the AIR COND panel 30VU: Release the related ENG BLEED pushbutton switch (the OFF legend comes on).	On the bleed-pressure regulator valve (4001HA): Make sure that the visual position indicator shows that the valve is closed.
4.In the cockpit, on the AIR COND panel 30VU: Push the related ENG BLEED pushbutton switch (the OFF legend goes off).	On the bleed-pressure regulator valve (4001HA): Make sure that the visual position indicator shows that the valve is open.
5.On the test set: Use the pressure regulator valve of the test set to decrease the pressure of the system to 0 psi (0.0000 bar).	On the bleed-pressure regulator valve (4001HA): The visual position indicator shows that the valve is closed.
	On the test set: The digital pressure gage shows that the pressure is to 0 psi (0.0000 bar).
