.
(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 fan air 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 fan air 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 fan air 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).

(a) Make sure that the pressure value shown on the GAGE - ABSOLUTE PRESSURE, DIGITAL, 0.001 BAR ACCURACY is equal to 0 psi (0.0000 bar).
(9) Make sure that the regulator valve of the test set is closed before you pressurize the system.

Subtask 36-11-00-720-068-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.

D. 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 primary regulator valve is mandatory. In this case pressurize will be limited to 217 psi (14.9616 bar).
2.On the test set (Z01): Open the shutoff valve.
3.On the test set (Z01): Use the pressure regulator valve of the test set to 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 1.6 psi (0.1103 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.
