Performance
The Basic Hood maximizes work area due to its unique single wall design. The
hood is available with or without a blower and in both an assembled or
unassembled configuration.
The hood features by-pass airflow design that promotes full containment as the
sash is moved. Airflow is diverted to behind the front panel and under the sash foil
to help minimize face velocity increases as the sash is lowered to the working
position the operator chooses.
!
If the unit is not operated as specified in this manual it may
impair the protection provided by the unit.
Si l'unité n'est pas utilisée comme spécifié dans ce manuel il
peut diminuer la protection fournie par l'unité.
Component Identification
1. Sash Foil. The sash foil is located directly underneath the sash opening of the
fume hood. The aerodynamic shape of the foil directs a smooth flow of air into
the hood with minimum turbulence. The sash foil is also part of the air by-pass
system on the hood, which allows a portion of the room air to flow under the
foil and into the fume hood. The by-pass airflow feature promotes full
containment as the sash is moved.
2. Adjustable Baffle. Epoxy-coated steel baffle features an adjustment slot to
change the internal airflow patterns within the hood. The slot adjustment is
regulated by loosening the baffle retaining knobs located directly on the baffle
and then pushing the upper portion of the lower baffle inward to expose the
slot opening in the baffle.
3. Tempered Safety Glass Sash. A vertical rising tempered safety glass sash
assembly allows the hood operator the flexibility of positioning the sash at any
suitable height for various procedures that he may perform within the fume
hood.

Chapter 1: Introduction
4. Light Fixture. The hood interior is illuminated by a single vapor-proof
incandescent light fixture. An explosion-proof incandescent light fixture is
also featured on the explosion-proof models. Both light assemblies are suitable
for use with a 100-watt light bulb.
5. Exhaust Connection. The hood features an epoxy-coated steel exhaust outlet
ring sized to accept either the built-in motor/blower assembly or a ten-inch
diameter plastic duct. When used with a remote blower, the exhaust duct slips
down directly over the exterior of the exhaust connection. The duct is then
attached directly to the exhaust connection ring using sheet metal screws and
caulking. When the built-in motor/blower is used, the exhaust duct is
connected directly to the exhaust connection on the blower itself. The
ductwork should be secured to the blower by using sheet metal screws and
caulking.
!
WARNING: The weight of the exhaust ductwork should be
supported independently of the hood structure as excess weight
could cause damage to the hood structure.
AVERTISSEMENT: Le poids des gaines d'échappement doit
être pris en charge indépendamment de la structure de la hotte
comme l'excès de poids peut causer des dommages à la
structure de la hotte.
6. Blower Assembly (not shown). A fractional horsepower motor/blower
assembly comes complete with a coated metal blower housing, exterior cover
and aluminum impeller wheel. Depending upon your specific application or
preference, the motor/blower assembly can be mounted directly in the top of
the fume hood or located externally in your duct run or on the roof itself.

Chapter 2: Installation
The electrical wiring of your hood is dependent upon your exact model. Review
the wiring diagrams for your specific hood located on pages 13 and 14 prior to
installation. All wiring should be done in accordance with local and National
Electrical Codes.
Le câblage électrique de votre hotte dépend de votre modèle exact. Passez en
revue les schémas de câblage pour votre capot spécifique situé sur les pages 13 et
14 avant l'installation. Tout le câblage doit être fait conformément aux codes
électriques locaux et nationaux.
If your hood is an explosion-proof model, it will not be internally wired. All
wiring for the enclosure MUST be done by a licensed electrician and conform to
all local codes. In most cases, the hood will require the use of conduit shielding
to protect the wiring being brought into the hood and the grounding connection of
the wiring shall be made in such a manner that the terminal box cover may be
removed without disturbing the electrical connections.
Sash Weight Release
The sash weight has been secured in the sash weight tracks located on the back of
your fume hood during shipment. The weight has been strapped to the bottom of
the hood back panel through the use of two plastic wire ties. Cut and remove
these ties to release the weight. Next, remove the cardboard packing material
placed behind the weight for shipment. Then slide the sash weight up to the top
position and attach the two sash cables directly into the slots provided on the
weight to begin proper operation.

Chapter 2: Installation
Placing and Sealing the Fume Hood
The Basic Hood performs best with the front of the lower airfoil placed flush with
the front of the work surface. Alternatively, the Basic Hood can be placed in
front of the work surface by one inch. The Basic Hood lower airfoil shall not be
placed behind the front edge of the work surface.
Once the Basic Hood has been set into position and all the plumbing and exhaust
ducting has been completed, it should be sealed to its work surface. The sealing
of the hood structure to the work surface will prevent any spilled materials from
collecting underneath the walls of the fume hood. Silicone sealant is normally
used for this purpose, and can be purchased locally or directly from Labconco.
Exhaust Connection for Hoods with
Built-In Blower
The exhaust connection on your Basic Hood with built-in blower features a round
exhaust outlet sized to accept ten-inch diameter PVC ducting. The exhaust duct
size allows for a minimum of static pressure loss through the hood at normal face
velocities and generates a sufficient transport velocity through the duct to safely
exhaust the toxic materials being handled in the laboratory hood.
The exhaust duct used on this hood will be under positive pressure during
operation. It is essential that all duct joints be sealed properly to eliminate the
possibility of leaking exhaust contaminants into your laboratory.
!
WARNING: The weight of the exhaust duct system must be
supported independently of the fume hood structure. Do not
allow the weight to be supported by the hood structure as
damage to the hood structure may result.
AVERTISSEMENT: Le poids du système de conduit
d'évacuation doit être soutenu indépendamment de la

CHAPTER 4
NORMAL OPERATION
Although the laboratory hood has been engineered to maintain the optimum in
operator safety, caution should always be used while working in the hood. Good
general housekeeping procedures with the following specific recommendations
should allow you to operate your laboratory hood safely.
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 store containers or supplies against the baffle, as this will affect
airflow through the hood. Blocking the bottom of the baffle will change
the airflow pattern in the hood causing turbulence and possible leakage at
the face of the hood.
Using flammable or explosive materials in this hood, unless it has been
equipped with explosion-proof components, is not recommended.
Do not work with or store chemicals in this hood without operating the
exhaust system.
Perchloric acid should not be used in this hood.
Radioisotope materials are not recommended for use in this hood.
The use of heat generating equipment in this hood without operating the
exhaust system may cause damage to the hood liner.
Seal all duct joints properly to prevent the leakage of any exhaust
contaminants from the duct.

Chapter 4: Normal Operation
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
Labconco follows the recommendations of the American National Standard
Institute with regards to fume hood exhaust systems. A full list of requirements
can be found in the ANSI Standard No. Z9.5 Laboratory Ventilation. If you are
unsure of the proper use of the exhaust blower for your fume hood, contact your
safety officer or industrial hygienist before making any modifications to the
constant negative pressure is an excellent way to ensure hazardous fumes in the
fume hood do not enter the laboratory space inadvertently.
Turn on the light.
Slowly raise the sash and verify the fume hood has proper airflow.
Check the baffle air slots for obstructions.
Allow the hood to operate unobstructed for two 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 (sill), 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 at least two
inches from the side walls and perform all contaminated operations as far
to the rear of the work area as possible.
Keep all clean and contaminated materials in the work area separate for
clear identification.
Avoid using techniques or procedures that disrupt the airflow patterns of
the hood.
16

Transient over-voltages according to Installation Categories II (Overvoltage Categories per IEC 1010). Temporary voltage spikes on the AC
input line that may be as high as 1500V for 115V models and 2500V for
230V models are allowed.
Used in an environment of Pollution degrees 2 (i.e., where normally only
non-conductive atmospheres are present). Occasionally, however, a
temporary conductivity caused by condensation must be expected, in
accordance with IEC 664.

APPENDIX B
ROUTINE MAINTENANCE
The exhaust blower motor has been factory lubricated for two years of
service. After this period 20 to 30 drops of SAE 20 automotive oil
annually is sufficient. Reference the nameplate on the motor for
additional oiling instructions.
Periodically check the belt tightness on the motor/blower assembly for
proper adjustment.
The belt on the motor/blower has been factory set at a desired tension
level. The tension on the belt can be measured by the amount of pressure
exerted to deflect the belt 1/2" from its normal position and this should be
approximately 5 pounds.
!
Do NOT contact blower wheel while still in motion.

APPENDIX C
PERFORMANCE TESTING
Your Labconco laboratory hood has been designed to allow you the flexibility of
setting your own face velocity based upon the work being performed inside of the
hood. The combination of your laboratory hood, exhaust duct, and exhaust
blower enables you to achieve this flexibility by regulating airflow across the sash
opening.
To determine the actual face velocity through 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 section on laboratory hoods in Industrial
Ventilation.
