Removing and replacing the nebulizer's impact bead
The AAnalyst nebulizer utilizes a ceramic, one-piece, impact-bead structure (P/N B050-5086)
which improves nebulization efficiency. The bead itself is held by two fragile support arms.
The bead structure mounts directly on the nebulizer's body assembly, see Figure 9- 14.
To Install Impact Bead
1. Hold the impact bead by its base and carefully push it onto the body of the nebulizer in front
of the venturi.
2. Then rotate it, holding only the base, approximately 1/8 turn clockwise, i.e., until it reaches a
stop.
