Original instructions
Location Requirements
The fume hood should be located away from traffic patterns,
doors, windows, fans, ventilation registers, and any other air-
handling device that could disrupt its airflow patterns. All
windows in the room should be closed.
La hotte aspirante devrait être localisé loin des voies de
circulation, des portes, des fenêtres, des ventilateurs, des
bouches de ventilation, et de tout appareil qui pourrait
interrompre ses voies de flux d'air. Toutes les fenêtres dans la
pièce devraient être fermées.
Support Requirements
DO NOT install the fume hood on a cart, dolly, or mobile
bench. ALL Protector XStream Hood installations must be
permanent and stationary. The supporting structure usually
consists of a base cabinet and chemically resistant work
surface.
NE PAS installer la hotte aspirante sur un chariot ou un banc
mobile. TOUTES les installations de la Hotte Protecteur
doivent être permanentes et fixes. La structure de soutien
consiste habituellement en un meuble doté d’une surface de
travail chimiquement résistante.
Exhaust Requirements
The exhaust duct connection has been designed for 12" nominal duct (12.75" OD)
to allow for minimum static pressure loss while operating at 50 to 100 fpm face
velocities. The 12" diameter exhaust duct also allows for proper transport
velocities away from the hood with minimal static pressure loss. Should higher
transport velocities of 1000 fpm to 2500 fpm be required, simply install a reducer
after the exhaust outlet. The exhaust volume and fume hood static pressure loss
are listed for each hood model at two sash heights and for face velocities from 40
to 100 fpm. When sizing the exhaust requirements, the choice must be made for
air foil, sash height and face velocity.
