If not, make sure you calibrated it. If needed, recalibrate it until it is correct. To do
this turn the hood off and reselect the sash type and then recalibrate it.
They should all match your notes from step 2 and your GFH settings sheet except
that the days will start over at 0 and count to 730 or the number that was entered.
***If everything was entered correctly, the filtered hood will function properly.
Otherwise you must turn it off and reenter the correct parameters. If you still have
a problem please contact Labconco Product Service.***
Certifying the Protector Echo Filtered
Fume Hood
The filtered hood gives you the flexibility to change the airflow at the sash
opening of your hood. To determine the actual face velocity at the sash opening,
airflow velocity readings will need to be taken. This should be done across the
sash opening of the hood in accordance with the Industrial Ventilation Manual
section on laboratory hoods (see Appendix E: References). Labconco
recommends an average face velocity at the sash opening of 60 to 100 feet per
minute. Consult Chapter 2 for proper airflow volumes for your particular model.
Your Protector Fume Hood has been tested at the factory per ASHRAE 110-1995.
All hoods achieve an “as manufactured rating” of less than 0.05 part per million
(ppm) at 4 liters per minute (lpm); AM<0.05 (consult Labconco for individual
fume hood ratings). For “field use” ASHRAE testing contact Labconco Sales
Engineering Team or Customer Service for a certified on-site contractor. A “field
use” ASHRAE method is used with isopropyl alcohol and a full report and
method is available upon request and posted on Labconco’s website.
NOTE: Face velocity profiles and smoke testing should be
done periodically to ensure safe performance.
NOTE : Les profils de flux frontal et les tests de fumée
devraient être régulièrement faits pour garantir une utilisation
en toute securité.
