Exhaust requirements for Canopy Exhaust Connection (CEC)
* = All exhaust flow rates are based on a nominal 105 fpm [0.533 m/sec] intake velocity.
** = When building exhaust is off, cabinet running.
If the cabinet intake varies from the nominal 105 fpm [0.533 m/sec], adjust the building exhaust flow rate to a
minimum of 20% over the intake airflow.
