Leak Checking Sample Lines - Honeywell Vertex M User Manual

4.9 Leak Checking Sample Lines

Perform a leak check of the sample lines following installation and also whenever a line is
changed or moved. The leak check procedure involves plugging the end of the sample line and
verifying that there is no flow through the line. To perform a leak check:
1. Put the affected Analyzer in Idle mode.
2. Choose Main Screen, Menu, Service, Authorized Service.
3. Select Analyzer.
4. Press pump on.
5. Securely plug the end of the sample line being tested.
6. Verify that the sample Point Vacuum equals the Supply Vacuum within a tolerance of +/-
0.5 inches Hg (see Point Vacuum (in Hg)) on "Verify Flow Rates" on page 73
7. Verify that the sample flow is less than 20cc.See Flow (cc/min) and (see Point Vacuum (in
Hg)) are links.
8. After testing all points on the selected analyzer, press Pump Off.
Note: The Pumps On button must be touched even if the pumps are operating. Touching
Pumps On turns on the solenoid valve to provide vacuum to the analyzer.
A sample point failing to meet both the flow and vacuum conditions of steps 6 and 7 indicates
either a leak in the sample line or a faulty sample inlet connection.
To troubleshoot the condition, disconnect the sample line at the inlet port at the top of the
Vertex M cabinet. Securely plug the inlet port and repeat the above leak check procedure.
If the sample point passes the test with the top port plugged, the leak is somewhere in the
sample line and the line must be replaced. If the sample point fails the leak check procedure
with the top inlet port plugged, contact Honeywell for assistance.
