Chapter 3: Getting Started

Sealing the Protector XLE Fume 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 Protector XLE Fume Hood

The combination of your laboratory hood, exhaust ductwork, and exhaust blower
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 D – Reference) Labconco recommends an
average face velocity at the sash opening of 80 to 100 feet per minute. Consult
Labconco Customer Service for proper airflow volumes for your particular model.

Your Protector XLE Fume Hood has been tested at the factory 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 contact
Labconco Sales Engineering Team or Customer Service for a certified on-site
contractor.

NOTE: Face velocity profiles and smoke testing should be

!

done periodically to ensure safe performance.

Performance Features

The Protector® XLE Laboratory Fume Hood is designed to meet the needs of the
laboratory scientist. The laboratory fume hood has been designed to effectively
contain toxic, noxious, or other harmful materials when properly installed. A
fully featured by-pass hood with baffle and air foil, this hood maintains safe
airflow. Optional energy saving A-Style Combination Sash models are also
available. The hood features by-pass airflow design that allows the hood face
velocity to remain relatively stable as the sash is closed. Airflow is diverted
behind the front panel and under the air foil to help control fluctuations in face
velocity, which occur as the sash is closed.

1. Unique sash provides maximum visibility of 35.00" high while
conserving energy by limiting sash travel to 28". Vertical-rising sash
may be raised from a closed position to 28" operating height. Optional
sash stops are available to limit sash height and reduce energy usage. The
sash can be locked open at the 28" height for loading and unloading
operations. When the upper sash lock is released the sash will
automatically lower to its designed operating height at 18". The sash can
be lowered manually to any position lower than the 18" operating position.

2. By-pass airflow design ensures relatively stable face velocities.

3. Large usable interior work depth and interior height of 48" provides
ample working space.

Chapter 4: Performance Features and Safety Precautions

Safety Precautions

Although the laboratory hood has been engineered to

!

)

!

maintain optimum operator safety, caution should always
be used while working in the hood. Prior to using the hood,
check to make sure that the exhaust blower is operating
and that air is entering the hood at its specified face
velocity.

USE GOOD HOUSEKEEPING IN THE HOOD AT ALL
TIMES. CLEAN UP SPILLS IMMEDIATELY WITH A
MILD DETERGENT. PERIODICALLY CLEAN HOOD
INTERIOR, INCLUDING FLUORESCENT LIGHT GLASS
PANEL. REPLACE BURNED OUT LIGHT BULBS TO
MAINTAIN MAXIMUM ILLUMINATION.

DO NOT OVERLOAD THE WORK SURFACE WITH
APPARATUS OR WORK MATERIAL. THE SAFE
OPERATION OF THE LABORATORY HOOD IS BASED
UPON HAVING PROPER AIRFLOW THROUGH THE
STRUCTURE. DO NOT PLACE LARGE, BULKY
OBJECTS SUCH AS BLOCK HEATERS, DIRECTLY ON
THE HOOD WORK SURFACE. INSTEAD, ELEVATE THE
OBJECT 2" TO 3" ON BLOCKS TO ALLOW A FLOW OF
AIR UNDER THE OBJECT AND INTO THE LOWER REAR
BAFFLE EXHAUST SLOT. ENSURE BLOCKS ARE
LEVEL AND SECURED IN PLACE.

Blocking the bottom of the baffle at rear of hood will
change the airflow pattern in the hood causing turbulence
and possible leakage at the face of the hood. (Don’t store
containers or supplies against baffles, as this will affect
airflow through the hood).

Avoid placing your head inside hood. Keep hands out of
hood as much as possible.

Always work as far back in hood as possible. It is best to
keep all chemicals and apparatus 6" inside the front of the
hood.

This hood does not feature explosion-proof electrical
components, unless ordered separately. Therefore, use of
flammable or explosive materials in quantities above the
explosive limit are not recommended.

Product Service 1-800-522-7658

19

Chapter 4: Performance Features and Safety Precautions

Do not work with chemicals in this hood without the
exhaust system running. Do not store chemicals in a fume
hood.

Perchloric acid use in this hood is prohibited.

High level radioisotope materials are prohibited for usage
in this hood.

DO NOT PLACE ITEMS ON THE AIRFOIL AS THEY
WILL EFFECT THE HOODS ABILITY TO CONTAIN.

)

!

AVOID CROSS DRAFTS AND LIMIT TRAFFIC IN FRONT
OF THE HOOD. AIR DISTURBANCES CREATED MAY
DRAW FUMES OUT OF THE HOOD.

The use of heat-generating equipment in this hood without
the exhaust system operating properly can cause damage to
the hood.

The Protector Laboratory XLE Hood should be certified by
a qualified certification technician before it is initially used.
The hood should be re-certified whenever it is relocated,
serviced or at least annually thereafter.

Ensure that the unit is connected to electrical service in
accordance with local and national electrical codes. Failure
to do so may create a fire or electrical hazard. Do not
remove or service any electrical components without first
disconnecting the hood from electrical service.

Proper operation of the fume hood depends largely upon
the hood’s location and the operator’s work habits.
Consult the Reference Manual in Appendix D.

Operating the Vertical-Rising Sash

Because of the Protector XLE Hood counterbalanced sash mechanism, it will take
only a few pounds of force to move the sash up or down between the fully closed
position and the 18" open position. You can operate the sash smoothly with one
or two hands positioned any where along the handle. The vertical-rising sash may
be raised to a maximum 28" operating height, but the sash will automatically
close back to the 18" opening position unless locked in the full open position.
The airflow requirements should be sized for the 18" operating height.

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.

S

A

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 XLE

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.

Product Service 1-800-522-7658

21

Chapter 5: Using Your Protector XLE

Start-up

• Turn on fluorescent light and hood blower.

• Slowly raise the sash to the 18" sash height position.

• 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

• Lock the sash in the upper position to load materials. 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.

• Release sash stop and allow sash to return to the 18" opening.

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.

Unloading Materials and Equipment

• Objects in contact with contaminated material should be surface
decontaminated before removal from the hood.

• All open trays or containers should be covered before being removed from
the hood.

Shutdown

• Turn off the fluorescent light and hood blower, then close the sash.
