Supply HEPA Filter Leak Test
All Logic models were tested to the HEPA Filter Leak Test as described in ANSI/NSF
Standard 49:2007.
Note: ensure all internal surfaces of the Logic have been appropriately
decontaminated before proceeding.
Note: For all Logic models, the prefilter element should be removed, and the
aerosol generator should be placed nearby to inject the aerosol as shown in
Figure 6-1.

Measuring the Upstream Concentration
The Logic utilizes a unique aerosol access tube for sampling the upstream concentration
of aerosol. If after reading these instructions, you have further questions, please
contact Labconco's Product Service Department.
Note: Logic B2 models manufactured prior to December 2010 (serial numbers
1011xxxxx and lower) have two sampling tubes. Disregard the tube on the
left side of the rear duct.
1. Remove the work surface by lifting the handles on either end. Pull the work
surface straight out of the Logic.
