3.  Install a vacuum gauge, regulator and isolation / shut-off ball valve in-line, onto the vacuum pump. With the ball valve 

closed, power on the vacuum pump. Adjust the regulator to 6.5" – 7" Hg maximum. Power the vacuum pump off.

4.  Remove the plug in the leak generator port on the SCCM. Connect the vacuum pump to this port.

5.  Power the vacuum pump on. Open the isolation ball valve slowly to evacuate the containment area to 6" Hg. Close the 

isolation ball valve:

• If the vacuum level does not increase after 30 seconds while the vacuum pump is running; large 

containments may take up to 10 minutes. Inspect each component for leaks.

• If the gauge drops below 6" Hg immediately after closing the valve then steadies before zero. 

Slowly open the isolation ball valve again to evacuate the containment to 6" Hg. Repeat as 

necessary until containment remains at 6" Hg and close the isolation ball valve. 

• If the gauge immediately drops to zero. This indicates that a leak exists. All leaks must be 

identied and repaired before continuing this test.

Note:  Vacuum leaks can be identied by pressurizing the containment area per the manufacturer’s specied levels, then 

spraying a solution of water and liquid soap on connections and ttings. Consistent bubbling on soaped connec-

tions/ttings will give a visual indication of the source of a leak. Consult the manufacturer’s documentation for

appropriate pressure levels.

6.  Once a stable vacuum level is reached (4.5" – 7" Hg on the vacuum gauge 

in-line with the vacuum pump), record the level. Use the table to the right 

to determine the required wait time. The containment vacuum level should 

remain stable throughout the entire wait time; the vacuum pump may be shut 

off at this point.

If the vacuum level drops more than 1" Hg during the required wait time, then 

the containment failed the test. All leaks must be identied and repaired rst, 

then the Containment Tightness Test should be repeated until it successfully 

completes.

7.  If a vacuum gauge has been installed at the end of the system, compare the

gauge reading with the console. If the measurements are not within ±2" Hg, a blockage may exist within the 

containment and/or between the SCCM and vacuum gauge. All blockages must be identied and corrected. Once the 

blockage is corrected, restart the Containment Tightness Test.

8.  Uninstall the vacuum pump, regulator, isolation / shut-off valve and vacuum gauges at this time. Continue on to the 

STP Vacuum Test in the next section. Do not replace the Leak Generator Port Plug.
