4.  Reinstall the grille by reversing the above sequence, ensuring that the 
grille properly engages the bottom edge of the cabinet. 
Towel Catch and Prefilter Removal: 
The towel catch should be removed periodically for inspection. 
Note: The work surface of the cabinet and the towel catch must be 
thoroughly decontaminated before removing either. 
1.  Remove the work surface as described above. 
2.  Remove the towel catch/prefilter assembly by pivoting the bottom out 
toward you, as shown in Figure 6-2a; it is spring loaded, and you will feel 
some resistance. Note the orientation of the towel catch. 
3.  Surface decontaminate the towel catch before removing it. Inspect the 
prefilters. Disinfect, clean or replace as necessary. Remove the prefilter 
elements by loosening the thumbscrew in the middle of the towel catch, 
and sliding the prefilters out of the towel catch, as shown in Figure 6-2b. 
Note: The metal prefilter elements used in the Procedure Station are 
washable, and can be autoclaved if necessary. 
4.  Reassemble the prefilters onto the towel catch, and reinstall the towel 
catch by sliding it back into position, in the correct orientation. Also 
ensure that the Sampling/Decontamination Tube (the black tube with an 
orange cap) rests behind the towel catch, allowing the catch to contact the 
rear wall of the cabinet.
