Original instructions
Operating the Blower
Your Protector Fume Hood utilizes a remote style blower, which can be activated
by turning the blower switch to “ON.” You can validate the hood performance by
watching smoke drawn into the hood face opening.
Operating the Lights
Your Protector Fume Hood utilizes a factory-wired fluorescent light to illuminate
the hood interior. Simply turn the light switch to “ON” to operate.
Working in your Protector Fume Hood
Planning

Thoroughly understand procedures and equipment required before
beginning work.

Arrange for minimal disruptions, such as room traffic or entry into the
room while the hood is in use.
Start-up

Turn on fluorescent light and hood blower.

Slowly raise the sash.

Check the baffle air slots for obstructions.

Allow the hood to operate unobstructed for 5 minutes.

Wear a long sleeved lab coat and rubber gloves. Use protective eyewear.
Wear a protective mask if appropriate.
Loading Materials and Equipment

Only load the materials required for the procedure. Do not overload the
hood.

Do not obstruct the front air foil, or rear baffle slots.

Large objects should not be placed close together and spaced above the
work surface to permit airflow to sweep under the equipment.

After loading the hood, wait one minute to purge airborne contaminants
from the work area.
Work Techniques

Keep all materials at least 6 inches inside of the sash, and perform all
contaminated operations as far to the rear of the work area as possible.

Segregate all clean and contaminated materials in the work area.

Avoid using techniques or procedures that disrupt the airflow patterns of
the hood.
Final Purging

Upon completion of work, the hood should be allowed to operate for two
to three minutes undisturbed, to purge airborne contaminants from the
work area before shutting down blower.
