Operating Procedures
Supreme Air Venturi Fume Hood Options
Tissue Screen
Your fume hood may be equipped with a tissue screen which is present to catch
any materials light enough to be swept up by fume hood airflow. The tissue
screen is located behind the rear baffles and can be accessed by removing the
Lower Rear Baffles. (see
Rear Baffle Removal and Adjustment
on page 7
)
Vent Holes
The fume hood worksurface may be supplied with optional vent holes which
provide exhaust to the fume hood base cabinets. These vent holes must remain
clear of debris. Any obstruction must be immediately removed.
Cord Pass Through
Your fume hood may have been supplied with optional Cord Pass Throughs
located in the fume hood sidewalls. These provide convenient and safe passage
of hoses, wires, and cords into the fume hood interior.
Safety Shield
Your hood may be furnished with a safety shield designed to provide protection to
fume hood users from small explosions, splattering of chemicals, breaking glass,
etc. The shield slides the full length of the hood face opening on ball bearing
rollers suspended from a track at the top of the sash opening, with a guide at
the bottom to keep the shield from swinging. During research and when the sash
must be open, a user should locate the safety shield in front of them-protecting
their face and torso-and working their arms around the safety shield. When the
shield is not in use, it can be easily removed from the upper track and stored until
it is needed again. Users should lubricant the ball bearings on an annual basis
with a white lithium grease.
Airflow Monitors
An airflow monitor is a safety device designed to notify a user of an unsafe airflow
condition with in their fume hood. To ensure maximum safety, the airflow monitor’s
power source should not be disconnected nor should any monitor parts within the
fume hood be disconnected.
The monitor must be calibrated after the building has been balanced. Once
calibrated, the monitor will give a visual and an audible alarm during a period
of unsafe airflow. In the event of an alarm, the user is advised to close the sash
fully and wait until the alarm stops. Once the alarm has stopped then a user may
continue to use the fume hood. If the alarm continues, even after the sash has
been fully closed, the user should contact the building maintenance supervisor
for further investigation.
For calibration, programming and operating instructions please refer
supplemental airflow monitor instructions.
