4. Procedure
Subtask 36-11-00-480-060-A ** ON A/C NOT FOR ALL

A. Installation of the Tool (HP Bleed Valve with the Deactivation Screw on the Regulator)

Functional Test of the Sense Line between the HP Bleed Valve (with the Deactivation Screw on the Regulator) and the Bleed-Pressure Regulator Valve ** ON A/C NOT FOR ALL

(1) Close the shutoff valve, the purge valve and the pressure regulator valve on the 98L36103002000 TEST SET - ENGINE BLEED (Z01).

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).

(2) Connect the AIR SOURCE 6.9 BAR (100 PSI) - REGULATED,FILTERED, DRY (Z03) to the 98L36103002000 TEST SET - ENGINE BLEED (Z01).
(3) 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 (Z01) to the SBE2213 KIT TOOL-TESTER SENSE LINE (Z02).
(4) Connect the GAGE - ABSOLUTE PRESSURE, DIGITAL, 0.001 BAR ACCURACY 2 to the valve 2 port of the sense line tester (T01) with the adaptor (T04).
(5) TORQUE the adaptor (T04) to between 1.1 and 0.9 m.daN (97.35 and 79.65 lbf.in )

.
(6) Removal of the deactivation screw 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 and discard the lockwire of the deactivation screw of the HP bleed valve.
(7) Remove the deactivation screw.

NOTE: Use a WRENCH 5/16 IN (8MM) - SPANNER if necessary.

(8) Connection of the sense line tester (T01) to the HP bleed valve:

CAUTION: FIRST TRY TO INSTALL THE ADAPTOR WITH THE SHORTEST THREADED AREA (T02). IF YOU CANNOT INSTALL IT, INSTALL THE OTHER ADAPTOR (T03). MAKE SURE THAT THE ADAPTOR (T02 OR T03) IS CORRECTLY HAND TIGHTENED.

(a) Connect the sense line tester (T01) to the HP bleed valve with the adaptor (T02) or (T03).

CAUTION: MAKE SURE THAT THE ADAPTOR (T02 OR T03) IS CORRECTLY HAND TIGHTENED.

(b) Apply force when you tighten the adaptor (T02) or (T03) with your hand.
(c) Make sure the valve 1 and valve 2 are in the open position (valves aligned with the pneumatic ducts).
(9) Do a reset of GAGE - ABSOLUTE PRESSURE, DIGITAL, 0.001 BAR ACCURACY gauges 1 and 2.

NOTE: The pressure value shown on the GAGE - ABSOLUTE PRESSURE, DIGITAL, 0.001 BAR ACCURACY must be equal to 0 psi (0.0000 bar).

(10) Make sure that the regulator valve of the test set is closed before pressurize the system.

B. Installation of the Tool (HP Bleed Valve without the Deactivation Screw on the Regulator)

Functional Test of Sense Line between the HP Bleed Valve (without Deactivation Screw on Regulator) and the Bleed-Pressure Regulator Valve ** ON A/C NOT FOR ALL

(1) Close the shutoff valve, the purge valve and the pressure regulator valve on the 98L36103002000 TEST SET - ENGINE BLEED (Z01).

(2) Connect the AIR SOURCE 6.9 BAR (100 PSI) - REGULATED,FILTERED, DRY (Z03) to the 98L36103002000 TEST SET - ENGINE BLEED (Z01).
(3) Connection of the test set.

(a) Connect the 98L36103002000 TEST SET - ENGINE BLEED (Z01) to the SBE2213 KIT TOOL-TESTER SENSE LINE.
(4) Connect the GAGE - ABSOLUTE PRESSURE, DIGITAL, 0.001 BAR ACCURACY 2 to the valve 2 port of the sense line tester (T01) with the adaptor (T04).
(5) TORQUE the adaptor (T04) to between 1.1 and 0.9 m.daN (97.35 and 79.65 lbf.in )

CAUTION: USE A SECOND WRENCH TO APPLY COUNTERTORQUE TO THE UNION WHEN YOU DISCONNECT/CONNECT THE PNEUMATIC LINES ON UNIONS.

(6) Disconnection of the sense line:

NOTE: Loosen the pneumatic union a quarter turn with a WRENCH 5/16 IN (8MM) - SPANNER. Then shake the sense line with your hand to prevent cross thread damage to the pneumatic union. To prevent damage to the fitting end of the sense line, turn the union with your hand and not with the WRENCH 5/16 IN (8MM) - SPANNER.

(a) Disconnect the sense line from the HP bleed valve.
(b) Put a PLUG - BLANKING on the HP bleed valve.
(7) Connection of the sense line adaptor (T04):

CAUTION: MAKE SURE THE ADAPTOR (T04) IS CORRECTLY TIGHTENED ON THE SENSE LINE.

(a) Connect the sense line adaptor (T04) to the sense line union and TORQUE to between 1.1 and 0.9 m.daN (97.35 and 79.65 lbf.in )

.
(b) Connect the sense line tester (T01) to the sense line adaptor (T04) with the hose (T05).
(8) Make sure that the valve 1 and valve 2 are in the open position (valves are aligned with the pneumatic ducts).
(9) Do a reset of all GAGE - ABSOLUTE PRESSURE, DIGITAL, 0.001 BAR ACCURACY 1 and 2.

NOTE: The pressure value shown on the GAGE - ABSOLUTE PRESSURE, DIGITAL, 0.001 BAR ACCURACY must be equal to 0 psi (0.0000 bar).

(10) Make sure that the regulator valve of the test set is closed before pressurize the system.

Subtask 36-11-00-720-064-A ** ON A/C NOT FOR ALL

CAUTION: DO NOT APPLY A PRESSURE OF MORE THAN 145 PSI (10 BAR). A HIGHER PRESSURE WILL CAUSE DAMAGE TO THE SENSE LINE.

C. Test

ACTION	RESULT
1.Pressurize the test set: If there is a manometer on the air cylinder then 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 100 psi (6.8948 bar). If there is no manometer in the air cylinder, then installation of the primary regulator valve is mandatory. In this case the primary regulator valve will limit the pressure in the test set to 217 psi (14.9616 bar).
2.On the test set (Z01): Open the shutoff valve.
3.On the test set (Z01): With the pressure regulator valve increase the pressure to 21.75 +0.75 psi or -0.75 psi (1.4996 +0.0517 bar or -0.0517 bar).	On the test set (Z01): The pressure value shows on the GAGE - ABSOLUTE PRESSURE, DIGITAL, 0.001 BAR ACCURACY 1.
4.On the sense line tester (T01): Close the valve 1.	On the sense line tester (T01): The valve 1 is not aligned with the pneumatic duct.
5.On the sense line tester (T01): Do a check of the pressure value shown on the GAGE - ABSOLUTE PRESSURE, DIGITAL, 0.001 BAR ACCURACY 2.	On the GAGE - ABSOLUTE PRESSURE, DIGITAL, 0.001 BAR ACCURACY 2: The pressure is more or equal to 5.8 psi (0.3999 bar).
6.On the AIR SOURCE 6.9 BAR (100 PSI) - REGULATED,FILTERED, DRY (Z03): Close the shutoff valve.
7.On the test set (Z01): Slowly open the purge valve to depressurize the test set.
