 B. Adjust the Altitude Pressure Switch 43MG
 (1)
 Remove the test adapter from the altitude pressure switch.

 (2)
 Use a 3/32 inch Allen wrench and adjust the screw in the center of the base of the switch.

 NOTE : You must turn the screw to the left to increase the altitude
____ pressure threshold of the switch. Turn the screw to the rihgt to decrease the altitude pressure threshold of the switch.
 NOTE : A 1/2 turn of the screw will give approximately 0.05 bar (0.77
____ psi) to 0.07 (0.96 psi) altitude pressure.
 (3)
 Install the test adapter and do the test in para 4. A. again.

 (4)
 If the test is not satisfactry, do the adjustment in para 4. B. again until the altitude is correct.

 C. Test
 (1)
 Make sure that the electrical connectors are clean and in the correct condition.

 (2)
 Connect the electrical connector to the altitude pressure switch.

 (3)
 Simulate the LGCIU 2 in the flight configuration on the CFDS (Ref. TASK 32-69-00-860-001).

 (4)
 Do the operational test of the vacuum toilet system (Ref. TASK 38-31-00-710-002).
