[1] Inflow nominal set point of 105 fpm was established with a direct airflow reading
    instrument. This nominal set point was confirmed using the manufacturer's recommended 
    alternate method with thermal anemometer in a constricted (3 inch high) access opening 
    (consult manufacturer for appropriate correction factor, if applicable), without
    adjusting cabinet airflow balance. The acceptable non-uniform downflow ranges listed
    above begin with zone 1 (54-64 fpm) closest to the back wall of the cabinet, zone 2
    (54-64 fpm) center of the cabinet, and end with zone 3 (40-50 fpm) closest to the front
    sliding window.  Downflow nominal set points were established with the I.V. Pole
    removed.  This cabinet model was Certified to NSF/ANSI 49-2020.  This cabinet qualifies
    only with the armrest installed. Certified for use with a power supply of 100V/50Hz/60Hz
    and 230V/50Hz/60Hz. Additional options are I.V. pole, canopy model BSCA-4C, casters and
    modified-passthrough.
