[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's operator's manual for appropriate correction factor) without
    adjusting cabinet airflow balance. Downflow nominal set point of 65 fpm was established
    with I.V. Pole and U.V. Light removed.  This cabinet model was Certified to NSF/ANSI
    49-2020. Canopy connection model number is 2FT-CC.
[2] Certified for use with power supplies of 230V/50Hz and 230V/60Hz.
[3] 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's operator's manual for appropriate correction factor) without
    adjusting cabinet airflow balance. Downflow nominal set point of 65 fpm was established
    with I.V. Pole and U.V. Light removed.  This cabinet model was Certified to NSF/ANSI
    49-2016. Canopy model 3FT-CC was evaluated as a part of the NSF Certification testing
    procedures.
[4] Inflow nominal set-point of 105 fpm was established with a direct airflow reading
    instrument. A corresponding inflow nominal set-point of 105 fpm (corrected to local air
    density) was confirmed using manufacturer's recommended alternate method with thermal
    anemometer in a constricted (3 inch high) access opening and applying appropriate
    correction factor without adjusting cabinet airflow balance. The downflow nominal
    set-point of 65 fpm was established 4 inches above the bottom of the sash with the I.V.
    Pole and U.V. Light removed. This cabinet model was Certified to NSF/ANSI 49-2014.
    Canopy model 4FT-CC was evaluated as a part of the NSF Certification testing procedures.
[5] 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's operator's manual for appropriate correction factor) without
    adjusting cabinet airflow balance. Downflow nominal set point of 65 fpm was established
    with I.V. Pole and U.V. Light removed.  This cabinet model was Certified to NSF/ANSI
    49-2016.
[6] Inflow nominal set-point of 105 fpm was established with a direct airflow reading
    instrument.  A corresponding inflow nominal set-point of 105 fpm (corrected to local air
    density) was confirmed using manufacturer's recommended alternate method with thermal
    anemometer in a constricted (3 inch high) access opening and applying appropriate
    correction factor without adjusting cabinet airflow balance.  The downflow nominal
    set-point of 65 fpm was established 4 inches above the bottom of the sash with the I.V.
    Pole and U.V. Light removed.  This cabinet model was Certified to NSF/ANSI 49-2014.
