Note Be sure that the preparation steps on pages 10 and 11 are complete before
proceeding with this test.

2. Wait approximately 15 seconds for equilibration.
If pressure cannot be achieved, either a very large leak is present in
the system, or the supply pressure is not high enough.

4. Note the “Actual” reading on the display and monitor the pressure for
10 minutes.
Press [Front Inlet] or [Back Inlet]. Move to the “Pressure” field and enter “25”.
