CAUTION:
Natural gas should be used only in the service
fixture that has been pre-plumbed with brass tubing. Sulfur
content of the gas could cause deterioration of standard copper
supply lines.
PRUDENCE : Le gaz naturel devrait être seulement utilisé dans
l'accessoire de service qui a été pré soudé avec des tuyaux de
cuivre. Le contenu soufré du gaz pourrait causer la
détérioration des lignes d’alimentation en cuivre standard.
Sealing the Fiberglass 30 Hood to the
Work Surface
When the hood has been set in place, ducted, wired, and plumbed, it should be
sealed at the work surface to prevent spilled materials from collecting under the
walls of the hood. Materials such as silicone sealants are recommended to seal the
hood structure.
Certifying the Fiberglass 30 Fume Hood
The combination of your laboratory hood, exhaust ductwork, and exhaust blower
give 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 D – Reference) Labconco recommends an average face velocity at
the sash opening of 80 to 100 feet per minute. Consult Chapter 2 for proper
airflow volumes for your particular model.
The Fiberglass 30 Fume Hood has been tested per ASHRAE 110-1995. All hoods
achieve an “as manufactured rating” of less than 0.10 part per million (ppm) at 4
liters per minute (lpm); AM<0.10 (consult Labconco for individual fume hood
ratings). For “field use” ASHRAE testing by a certified technician, contact
Labconco Customer Service.
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.
