6.3.2.2 Setup and test:
Step 1) Plug the outlet side of the DISS fitting.
Step 2) Connect the tube (originally connected to ATF) to oxygen or nitrogen gas at 10 ± 1 psig.
Step 3) Using a pressure gage with 0-15 psig range, verify the system is pressurize to 10 ±1 psig.
Step 4) Once the system is pressurized, shut the supply valve on the pressure source.
Step 5) Start timing for 60 seconds.
Step 6) Verify that the pressure did not drop more than 1.8 psig for the 60 second test.
NOTE:
If a leak is found, check the connection, at which tubing was removed and
reconnected. Repair of the leak can be done by cutting ½” of tubing and
reconnecting, so tubing sealing will be re-established. Repeat the test.
