Before you install your laboratory fume hood, you need to prepare your site for
installation. Carefully examine the location where you intend to install your
hood. You must be certain that the area is level and of solid construction. In
addition, a dedicated source of electrical power must be located near the
installation site.

Carefully read this chapter to learn:

 The location requirements for your installation site.
 The support requirements for your installation site.
 The exhaust requirements for your installation site.
 The electrical power requirements for your installation site.
 The service line requirements for your installation site.
 The space requirements for your installation site.

Refer to Appendix B: Protector ClassMate Dimensions for complete fume hood
dimensions.

Refer to Appendix C: Protector ClassMate Specifications for complete laboratory
fume hood electrical and environmental conditions, specifications and
requirements.

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

Location Requirements

The fume hood should be located away from traffic patterns,
doors, windows, fans, ventilation registers, and any other air­handling 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 locate the fume hood on a cart, dolly, or mobile
bench. ALL Protector ClassMate installations must be
permanent and stationary. The supporting structure usually
consists of a base cabinet and chemically resistant work
surface. See Appendix D: Protector ClassMate Accessories.

Ne pas placer la hotte sur un panier, chariot, ou banc mobile.
Toutes les installations de protection camarade de classe
doivent être permanents et fixes. La structure de support est
généralement constitué d'une armoire de base et la surface de
travail résistant aux produits chimiques. Voir Annexe D:
Protector ClassMate accessoires.

Exhaust Requirements

The exhaust duct connection has been designed for 8" nominal pipe (8.625" O.D.)
to allow for minimum static pressure loss while operating at 100 fpm face
velocities. The 8" exhaust duct also allows for proper transport velocities away
from the hood in the 1000 fpm to 2500 fpm range. It is acceptable to combine the
air from two hoods with a transition coupling that would basically have two 8"
nominal exhaust inlets and one 12" (12.00" O.D.) nominal exhaust outlet. See
Appendix D Protector ClassMate Accessories for transition coupling. The proper
exhaust volume and static pressure loss are listed next for each hood model:

Sealing the Protector ClassMate Hood

When the hood has been set in place, ducted, wired, and plumbed, it should be
sealed at the work surface. The sealing of the hood structure to the work surface
will prevent spilled materials from collecting under the walls of the hoods.
Materials such as silicone sealants may be used to seal the hood structure.

Certifying the Protector ClassMate Fume
Hood

The combination of your laboratory hood, exhaust ductwork, and exhaust blower
enables you flexibility to change the airflow generated across the sash opening on
the hood. 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 Industrial Ventilation Manual section
on laboratory hoods. Labconco recommends an average face velocity through the

reduced hood opening of 60 to 100 feet per minute. Reference airflow’s for your

particular model in Chapter 3 Fume Hood Components.

Theory of Operation

The Protector® ClassMate Laboratory Hood is designed to meet the needs of
the science instructor. Clear back and sides and taller front viewing window
provide enhanced visibility for the instructor conducting chemistry
demonstrations or observing students using the hood. The ergonomic inclined
front promotes additional visibility into the laboratory. The clear back also
does not obstruct visibility when hoods are placed back-to-back in an island
configuration. A fully featured by-pass hood with baffle and airfoil, this hood
maintains safe airflow while sash opening restriction conserves energy. The
Protector ClassMate Hood is offered in 4', 5', and 6' widths. Additional 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 and
under the airfoil to help control fluctuations in face velocity, which occur as
the sash is closed.

The major components in Protector ClassMate Laboratory Hoods are outlined
as follows and in Figure 4-1, and Figure 4-1A:

1. Clear, tempered safety glass sides, back and baffle provide maximum

visibility. All glass components except sashes are removable for cleaning.
Visibility up to 45" on sides and back.

2. Unique sash provides maximum visibility of 39" high while conserving

energy. Vertical-rising sash may be raised from a closed to 18" operating
height. Exhaust volume, and blower sizing is based on the 18" height. For
loading and cleaning, the sash raise up above the sash stop.

Original instructions

3. Anti-racking shaft provides smooth vertical sash movements.

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

5. Large usable interior work depth of 26" and interior height of 48"

provide ample working space.

6. Baffle directs airflow to the rear of the interior to provide efficient airflow.

The baffle may be removed or pivoted down for cleaning purposes only.

7. Tissue Screen located directly below the exhaust outlet prevents debris

from potentially damaging the remote blower.

8. Interior cover plates are removable for easy access to plumbing.

9. Lift-away front panel provides easy access to electrical wiring, sash

weights, and lighting fixtures.

10. Energy efficient fluorescent lighting is located behind a tempered safety

glass shield mounted to the top of the hood interior. The factory wired
light is serviceable from outside the hood cavity.

11. Low mounted, factory wired light and blower switches are ADA

compliant.

12. Ergonomic airfoil allows air to sweep work surface for maximum

containment and provide a Patented Clean Sweep™ on the upper surface to

provide maximum containment.

13. Low profile trough below airfoil contains spills. The trough is the same

depth as the work surface (1.25") and requires no cabinet overhang.

14. Streamlined corner posts provide maximum visibility.

15. All hoods are factory prepared for up to 8 service fixtures (four

controlled from the front of the hood and four from the base cabinet). Four
service fixtures are factory installed on fixtured models. ADA compliant
fixtures are fully plumbed with copper tubing. The upper right fixture is
brass for gas service. Because the fixtures are remotely controlled, they
can be used regardless of sash position.

16. Duplex electrical receptacles are mounted on the right and left fixture

panels on fixtured models to allow convenient and safe connections.
Receptacles are factory wired to hood junction boxes.

17. Shipped fully assembled and eliminates the need for costly onsite

assembly.

18. Accessory Guardian™ Digital Airflow Monitor continuously monitors

face velocity. An audio/visual alarm alerts the user to low airflow
conditions. The front panel can be factory prepared to accommodate the
Guardian Digital Airflow Monitor (sold separately).

19. Energy Reducing A-Style Combination Sash Models. See Figure 4-1A.

Clear static viewing panel above the sash frame has a 39" viewing height
permitting the hood to be mounted in a low or high position to
accommodate persons of different heights and still maintain the same

visual accessibility. The 4' hoods have a single vertical rising sash; 5' and
6' hoods have combination horizontal sliding/vertical rising sashes. These
combination sashes allow the operator to use the hood with sashes either
half open vertically or horizontally to conserve energy. Two sets of
integral sash stops prevent raising the vertical sash above the half-open and
fully closed positions unless manually defeated by the operator.

20. Epoxy coated steel sash enclosure located behind the front panel prevents

laboratory exposure to contaminated interior sash surfaces for energy
saving A-Style models only.

21. Frame of epoxy coated steel and aluminum is durable and corrosion

resistant.

22. Exhaust Connection. The hood features 8" (8.62" O.D. pipe) molded

exhaust connections sized to allow for a minimum static pressure loss
through the hood structure while providing a good transport velocity
through the exhaust system. Dual exhaust Adapter is sold separately.

23. Accessory solid Epoxy Work Surface is dished to contain spills. Work

surface is sold separately.

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 the proper velocity of 100 fpm.

Bien que la hotte de laboratoire a été conçu pour maintenir une
sécurité optimale de l'opérateur, la prudence doit toujours être
utilisé tout en travaillant dans la hotte. Avant d'utiliser la hotte,
assurez-vous que le ventilateur d'échappement est en marche et
que l'air entre dans la hotte à la bonne vitesse de 100 pieds par
minute.

USE GOOD HOUSEKEEPING IN THE HOOD AT ALL TIMES.
CLEAN UP SPILLS IMMEDIATELY. 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, PLACE THE OBJECT ON A BLOCK UP 2" TO 3"
TO ALLOW A FLOW OF AIR UNDER THE OBJECT AND
INTO THE LOWER REAR BAFFLE EXHAUST SLOT OF THE
HOOD. ENSURE BLOCKS ARE LEVEL AND SET 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).

Le blocage de la partie inférieure de la chicane à l'arrière du
capot va changer le modèle d'écoulement d'air dans la hotte
provoquant une turbulence et une fuite possible à la face du
capot. (Ne pas entreposer les contenants ou des fournitures
contre chicanes, car cela aura une incidence sur le débit d'air à

Now that you have an understanding of how to work in the fume hood, we will
review the suggested maintenance schedule and the common service operations
necessary to maintain your fume hood for peak performance.

Only trained and experienced certification technicians should
perform some of the service operations after the fume hood has
been properly decontaminated. DO NOT attempt to perform
these operations if you are not properly trained. The wrench
icon precedes the service operations that require qualified
technicians.

Techniciens de certification Seulement formés et expérimentés
devraient effectuer certaines des opérations de service après la
hotte a été correctement décontaminés. NE PAS tenter de
réaliser ces opérations si vous n'êtes pas correctement formés.
