5. Remove the thicker, 1-207 face-seal O-ring (6006680) from the bottom

C a u t i o n
The 1-207 O-ring (6006680) is made of conductive material to ensure
that the impactor is grounded to the classifier chassis. It should not be
replaced with a substitute 1-207 O-ring.
If you set the O-rings on a dirty surface, they will pick up debris. Perform
a visual inspection and remove debris with a clean wipe.
7. Slot new O-rings into the correct grooves in the impactor body.
To replace the 1-025 O-ring (6006389) from the classifier inlet, follow
these instructions:
1. If an impactor or inlet adapter is installed in the inlet of the classifier,
remove it.
2. Locate the O-ring.
