Before You Start
Shipping Information
Inspect all cartons and boxes for flaws and shipping damages. If anything is discovered to be damaged, contact the shipping
company and file a freight claim.
Filter Information
Ensure that all HEPA/ULPA filters are stored in a clean, dry location in a vertical position, as labeled on the carton. Do not
open the HEPA/ULPA filters until they are ready to be installed in the Krown Fan Filter Units. All construction in the space
should be complete, the site and upstream air should be clean so as not to unnecessarily load the filter.
Ensure ductwork is balanced to scheduled flow and that both the space and ductwork is clean, free of debris, and ready for
operation prior to installation of filter. To ensure fan filter units are properly balanced, read
Technical Note: Design with VAV/
Constant Flow Boxes and Ducted Applications
prior to starting installation.
A minimum of two (2) people will be required to install the filters.
NOTE:
Extreme caution should be taken to avoid contact with filter media. Touching filter media may result in filter failure.
Damage to filters can occur during installation or during leak qualification testing. The filters supplied by Keystone have
been 100% tested and certified by the manufacturer to be free of defects and leaks. Keystone cannot accept responsibility
for damage that occurs after shipment, whether through transit, handling or installation, and will not replace filters under
Keystone standard warranty.
