WARNING
The Model 3077A/3077 Aerosol Neutralizer, which is installed inside the
Model 3080 Electrostatic Classifier, contains radioactive material that is
subject to the regulations of the U.S. Nuclear Regulatory Commission
and local regulations. Carefully read the enclosed Model 3077/3077A
Aerosol Neutralizers Instruction Manual to determine your legal
responsibilities regarding the neutralizer.
Before the Classifier will operate, the neutralizer must be installed
according to the following steps:
1. Remove the two screws securing the neutralizer outlet block on

2. Inspect the ¼-in tubes on the neutralizer to make sure that the
ends do not have sharp edges. If the outer edges of the ends are
sharp, they will cut the O-ring seals in the Classifier and cause
a leak. Remove any sharp edges using a fine file or fine grit
sandpaper suitable for stainless steel.
3. Put a light coating of grease on the outer diameter of the ¼-in
tubes on the neutralizer.
