4. Place photometer pickup over the exhaust
discharge and sample the concentration. The
concentration must not exceed 0.005%.
5. If the unit fails, check the gasket between the
control panel and the upper cabinet flange.
Also, check gasket attached to underside of the
upper cabinet for contact with the upper edge of
the sash when it is in the closed position.
6. Use a Laskin nozzle-type generator. DO NOT
use more than one nozzle. Operate the
generator at 10 PSIG. The calculations listed

as an aerosol challenge. You may need to
correct the valves listed if you use an alternate
fluid.
7. Place the generator discharge near the work
access opening of the enclosure.
8. Start the generator. Ensure that only one nozzle
is operating at 10 PSIG.
9. To establish the downstream concentration of
aerosol, place the photometer pick up over the
exhaust discharge, and sample the concentration
at several locations.
10. The average concentration at each of the points
must not exceed 0.005% of the upstream
concentration.
