4.  Thoroughly clean the nozzle sealing surface and the vane crosshairs with a cotton-tipped 

applicator and isopropyl alcohol (see Figure 5-6). Any hardened deposits may have to be 
carefully scraped off with the wooden end of the applicator.

5.  Inspect the nozzle lip and vane for any burrs which may cause leaks or tape damage. 
6.  After the cleaning process, it is recommended to use canned dusting air to blow down 

through the vane crosshairs. This removes any filter debris from the face of the beta 
detector, which is located directly under the vane. Be careful not to damage the beta detector 
window! 

7.  Reinstall the filter tape and perform a final leak check. 

Figure 5-7 shows the difference between good and bad filter tape spots. The tape on the right is 
from an E-BAM with a clean nozzle and vane. The particulate spots have crisp edges, are perfectly 
round, and are evenly distributed. The tape on the left is from a unit with a dirty vane. A spot of 
debris has built up and is punching a pin-hole at the edge of each spot. The spots also show a 
“halo” effect from an air leak because the debris has built up to the extent that the nozzle no longer 
seals correctly. These faults are easily prevented by keeping the nozzle and vane clean.
