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.
