A. Fault Confirmation Test
(1) Do the leak check of the Vacuum Toilet System (Ref. AMM TASK 38-31-00-790-002).
4. Fault Isolation
_______________
A. If the required negative differential pressure (Ref. to the GRAPH 1 and GRAPH 2 in figure 503 of the AMM TASK 38-31-00-790-002) is lower than the measured value:
- Examine the toilet drain lines for leaks with the vacuum system under pressure.
(1) If you find leaks, repair or replace the defective toilet drain lines (Ref. AMM TASK 38-30-00-010-002) and (Ref. AMM TASK 38-30-00-410-002).
