If you have a leak checker:

1. Turn off power to the analyzer and 501Y, and unplug the external Pump.

2. Disconnect the external Pump from the analyzer’s rear panel. Cap the

sample inlet of the external Converter, the BYPASS OUT port of the 501Y,

the ozone generator air inlet (located inside the analyzer, Figure 6), and

connect the leak checker to the instrument exhaust port.

CAUTION!

Pressure must be less than 15 PSI.

3. Pressurize the system and check for leaks by watching overall pressure.

The pressure should not drop more than 1"Hg (.5psi) in 5 minutes.

If the instrument fails the pressure test, each fitting needs to be leak checked to

find the location.

NOTE

Be careful that the system is always pressurized so as not to draw soap solution into the

plumbing system. Make sure you dry off any accumulated bubble solution. Start by

checking the external fittings first.
