Sealing rack air leaks
After you have attached all the conduit to the rack and connected all wiring,
you must seal any air leaks in the rack cabinet created during the installation
process. Use urethane aerosol foam to fill air gaps in conduit.
1. Seal all conduit access holes.
2. Re-install access panels removed during installation, or completely cover
their openings with fiche paper and urethane aerosol foam.
3. Seal any air gaps caused by bent access panels.
4. Fill in any gaps inside partially filled wiring conduit.
5. Fill in other gaps or holes in the cabinet created during installation.
