Performing a Delivery Test
Select the category of delivery test, and then double-click on the individual 1.
valve to be tested in the Test window (or click Test to test all valves within the
category).
The Liberty will vent all pressure from the lines. The valve will be closed and the 2.
line pressurized, then the nitrogen turned off. The Liberty will wait to see if there
is a decrease in pressure. A decrease in pressure indicates the valve is leaking,
and will cause the test to fail. If the test fails, contact CEM Service for help with
troubleshooting.
The valve will then be opened and the pressure should vent. Failure to vent 3.
pressure indicates the valve is not opening or the line is restricted, and will cause
the test to fail. If the test fails, contact CEM Service for help with troubleshooting.
