Chapter 2: Prerequisites
Support Requirements
At a minimum, the supporting structure usually consists of a base cabinet, or
a base stand and chemically-resistant work surface. When setting up a
chemical station, a mobile stand or cart is allowable. Labconco manufactures
a mobile cart with work surface specifically designed to support the Protector
Demonstration Hood and FilterMate Portable Exhauster. The cart is supplied
with the Mobile Protector Demonstration Hood or can be ordered separately
as an accessory. See Chapter 7 for accessories.
Location and Air Current Requirements
The Protector Demonstration Hood has been designed to contain hazards by
negating typical cross drafts and movements within the opening. As a
precautionary measure it is recommended that the enclosure be placed in such
an area away from:
• High traffic areas where walking might cause an air disturbance.
• Overhead or wall HVAC diffusers, fans, radiators or other lab equipment
producing air currents.
• Next to doorways or windows that may be opened.
Exhaust and Blower Requirements
The exhaust connection has been designed to accept a 2" x 10" (5.1cm x
25.4cm) nominal exhaust collar. The Protector Demonstration Hood has two
possible exhaust connections with either the top exhaust open and the bottom
exhaust closed or vice versa. The bottom exhaust connection is primarily
used in installations where the hose or ductwork will be concealed. The
bottom exhaust is used on the Mobile Protector Demonstration Hood to
conceal the exhaust and facilitate connection to the FilterMate Portable
Exhauster. Labconco offers accessory Transition Adapters for the top or
bottom exhaust connection to either a 5" hose or 6" duct. (See Chapter 7 for
ordering any of these accessories). Only one exhaust connection is required.
The mobile Protector Demonstration Hood includes the lower 5" hose
exhaust transition, FilterMate Portable Exhauster, 5" hose, mobile cart and
work surface. Data for the exhaust volume and enclosure static pressure loss
are listed for each model at face velocities of 60, 80 and 100 fpm.

Chapter 2: Prerequisites
Proper blower selection can be determined from these exhaust requirements
and the total system static pressure loss. The enclosure must be connected to
either a dedicated blower, a house exhaust system or a dedicated filtered
exhauster, such as a Labconco FilterMate Portable Exhauster.
Labconco offers three accessory remote blowers listed in Chapter 7.
Electrical Requirements
Standard duplex electrical receptacles should be nearby for connecting the
Demonstration Hood, FilterMate Portable Exhauster, an airflow monitor,
accessory Fluorescent Light or other equipment. For your convenience both
the accessory FilterMate and accessory fluorescent light kit have auxiliary
outlet receptacles. It is required that the airflow monitor be connected
directly to the auxiliary switched outlet on the rear of the FilterMate so the
airflow monitor is ON when the blower is ON. The FilterMate auxiliary
switched outlet is rated for 8 amps.
For other blower exhaust systems, it is recommended that the airflow monitor
be switched by the same circuit as the exhaust blower. If this is not possible,
then the airflow monitor may be connected to the switched auxiliary outlet on
the accessory fluorescent light kit. The fluorescent light kit auxiliary outlet
can be used for any accessory under 8 amps.
Space Requirements
The dimensions for the different models are shown in Appendix B:

Chapter 3: Getting Started
Connecting the Electrical Supply
A standard duplex receptacle should be nearby for connecting the FilterMate
Portable Exhauster, airflow monitor and accessories. Please review Chapter
2 for electrical prerequisites.
All wiring for the building duplex outlets SHOULD be performed by a
licensed electrician and conform to all local codes.
Sealing to the Work Surface
When the hood has been set in place, ducted and wired, it may be sealed at
the work surface to prevent spilled materials from collecting under the walls.
A bead of silicone sealant is recommended to seal the hood to the work
surface.
Validating the Hood
The exhaust damper, exhaust blower or FilterMate gives you the flexibility to
change the airflow at the sash opening of your enclosure. Determine the
actual face velocity at the sash opening by taking airflow velocity readings.
These should be taken across the sash opening of the enclosure in accordance
with the Industrial Ventilation Manual. (See Appendix D) The “average face
velocity” is achieved by taking readings in two rows across the enclosure
with the readings 6" from the ends and evenly spaced every 12"; the first row
is 3" down from the upper sash foil and the second row is 3" up from the
work surface. Labconco recommends an average face velocity at the sash
opening of 60 to 100 feet per minute for Protector Demonstration Hoods.
Refer to Chapter 2 for proper airflow volumes for your particular model.
Your Protector Demonstration Hood has been tested at the factory per
ASHRAE 110-1995. All enclosures achieve an “as manufactured rating” of
less than 0.05 part per million (ppm) at 4 liters per minute (lpm); AM <0.05
(Consult Labconco for individual ratings). For “field use” ASHRAE testing
contact Labconco for a certified on-site contractor.
NOTE: Face velocity profiles and smoke testing should be performed
frequently per your organization’s quality system to ensure safe
performance.

High Performance Features:
The patented (U.S. Patent No. 6,461,233) Protector Demonstration Hood
is designed to meet the needs of a variety of laboratory applications, and
provide superior containment while conserving energy at OSHA
approved “low flow” velocities as low as 60 feet per minute. The
Protector Demonstration Hood has been designed to effectively contain
toxic, noxious, or other harmful materials when properly installed and
operated. What makes the Protector Demonstration Hood so unique is
the revolutionary way it directs air into and through the contaminated air
chamber. Labconco engineered the hood to minimize the effects of
turbulence. The containment enhancing and aerodynamic designs of the
upper sash foil, side air foils, lower air foil, upper dilution air supply, and
rear baffle all work in concert to produce airflow patterns that
significantly reduce both powder and chemical concentrations through the
work area. The Protector Demonstration Hood incorporates unique 360°
visibility, which is useful in laboratory demonstrations and visibility
across classrooms.

Chapter 4: High Performance Features and Safety Precautions
1. Aerodynamic Clean-Sweep™ Air Foil has a unique low profile
shape that allows air to sweep the work surface for maximum
containment. The Clean-Sweep™ openings create a constant
protective barrier from contaminants. In addition, should the operator
inadvertently block the airflow entering the air foil, air continues to
pass under the air foil and through the Clean-Sweep openings. See
Figure 4-2.
Figure 4-2
2. Containment-Enhancing Upper Sash Foil includes a perforated air
passage directly atop the sash foil to bleed air into the hood chamber
and direct chemical and powder concentrations away from the sash
opening. The radiused sash foil sweeps airflow into the hood with
minimal turbulence. See Figure 4-3.
Figure 4-3
Product Service 1-800-522-7658

Chapter 4: High Performance Features and Safety Precautions
3. Upper Dilution Air Supply provides bypass air from above the work
area. This feature constantly bathes the sash interior with clean air and
reduces powders and chemical fumes along the sash plane, near the
critical breathing zone. Five to seven percent of the required air
volume is introduced through the upper dilution air supply to ensure
maximum containment. Additionally, the upper dilution air supply
reduces stagnant pockets of air in the upper interior. See Figure 4-4.
Figure 4-4
4. Visible Clear Rear Baffle directs air streams to the baffle in a single
pass. The baffle and rear panel are manufactured from framed glass
panels to provide maximum visibility on all sides. This smooth flow
minimizes the potential for air to roll forward preventing
contamination from moving toward the sash opening. The
concentrations of materials are largely removed on the first pass
through the contaminated chamber.
5. Side Entry Air Foils allow turbulence-free air to enter the hood from
the sides and allow clean air to sweep the interior walls.
6. Ergonomic Slope provides maximum visibility, and comfort reduces
glare, thereby minimizing operator fatigue.
7. Internal Depth of 23" provides necessary space to support
equipment without extending outside the hood or resting on the lower
air foil.
8. Two Heights available as standard enclosures in 22.75" or 32".
Taller height Demonstration Hoods are typically used for pipet
operations, titration or taller auxiliary equipment.
9. Unique Flush Sash with Spring-Loaded Latch has a wiping seal to
contain contaminants and features a spring-loaded latch for loading
auxiliary equipment. The sash pivots down for normal operation.

Product Service 1-800-522-7658
Chapter 4: High Performance Features and Safety Precautions
10. Electrical Pass through Iris allows electrical cords and data cords to
pass through the back of hood without leaving a large hole for
contaminants to escape. The hood ships with solid plugs and the iris
plugs are included with the instruction manual for your convenience.
11. Shipped fully assembled to eliminate the need for costly onsite
assembly. Accessories such as the exhaust transition connections,
work surfaces, airflow monitors and fluorescent light kits are easily
installed.
12. Accessory Exhaust Connections. The Protector Demonstration
Hoods feature two exhaust locations: One is located on the top of the
rear plenum and the other is located on the bottom of the rear plenum.
The bottom exhaust incorporates a tissue screen to prevent debris
from clogging the exhaust blower. Exhaust transition connectors are
available for either a 6" OD outside exhaust or a 5" ID hose. All
exhaust transition connectors are illustrated in Chapters 2 and 3 and
accessories listed in Chapter 7. The lower 5" ID hose exhaust
connection is used with the mobile cart for connection to the
FilterMate Portable Exhauster which rests on the lower shelf.
13. Accessory Guardian™ Digital 1000 Airflow Monitor or Guardian
500 Monitor continuously monitors airflow. An audio/visual alarm
alerts the user to low airflow conditions. The Guardian™ 1000
Digital Airflow Monitor also displays a face velocity value, provides
an RS232 output, a night setback mode and several auxiliary relay
ports. See Chapter 7 for ordering information. See Chapter 6 for
details, installation and calibration.
14. Accessory Fluorescent Light Kits provide excellent illumination
with an auxiliary outlet plug for supplying power to auxiliary
equipment such as a balance or printer. See Chapter 7 for ordering
information.
15. Accessory Roof-Mounted Blower sized to provide adequate airflow
to Protector Demonstration Hoods when used with an exhaust
damper. See Chapters 2, 3 and 7.
16. Accessory FilterMate Portable Exhauster provides up to 280 cfm
for HEPA or Carbon filtration or up to 220 cfm for combination
HEPA/Carbon filtration when connected to the hood. See Chapters 2,
3 and 7.
17. Mobile Demonstration Hood includes FilterMate Portable
Exhauster, Demonstration Hood, work surface and mobile cart to
allow easy transport throughout the facility. See Figure 3-6. Mobile
cart can be ordered separately as shown in Chapter 7.

Chapter 4: High Performance Features and Safety Precautions
Safety Precautions
Although the hood has been engineered to maintain optimum operator
safety, caution should always be used while working. 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. The use of an
airflow monitor is recommended to alert the user if there is a problem
with airflow.
Use good housekeeping in the hood at all times. Clean up spills
immediately. Periodically clean enclosure interior.
Do not overload the work surface with apparatus or work material. The
safe operation of the hood is based upon having proper airflow through
the structure. Do not place large, bulky objects such as block heaters,
directly on the work surface. Instead, elevate the object 3/4" on blocks
to allow a flow of air under the object and into the rear baffle exhaust
slots. Ensure blocks are level and secured in place.
Blocking large portions of the rear baffle will change the airflow pattern
in the hood causing turbulence. (Do not store containers or supplies
against the rear baffle, as this will affect airflow).
Always work with your hands as far back in the hood as possible. It is
best to keep all powders, chemicals and apparatus inside the lower air
foil of the hood.
Do not work with chemicals in this hood without the exhaust system
running. Perchloric acid use in this hood is prohibited.
High-level radioisotope materials are prohibited in this hood.
Avoid cross drafts and limit traffic in front of the hood. Air
disturbances created may draw contaminants out of the hood.
The hood should be tested by a qualified certification technician before it
is initially used. The hood should be validated whenever it is relocated,
serviced or at least annually thereafter.
The use of safety goggles, protective clothing, gloves and any other
personal protective equipment recommended by your safety officer
should be used.
The sash should remain in the down position while using the hood.
Proper operation of the hood depends largely upon its location and the
operator’s work habits. Consult the references in Appendix D.

The Guardian 500 Airflow Monitor is designed to continuously monitor airflow
through enclosures and fume hoods. This permanently installed device provides both
visual and audible alarms to alert the user of abnormal airflow conditions. A green
light on the front of the monitor indicates normal flow conditions. When flow
conditions lower than the set point are encountered, a flashing red light is activated
along with an audible alarm. To temporarily mute the audible alarm, press and
release the test/reset button. The Guardian 500 Airflow Monitor has a built-in sensor,
3 relay inputs and 1 relay output. The relay inputs can be configured for night
setback, external alarm, and sash high alarm. The night setback features disables the
alarm. The relay output is configured for Low Air Alarm.

Guardian 500 Calibration Procedure
Each alarm module and enclosure/fume hood is unique and needs to be individually
calibrated in the field. The procedure for the adjustment is as follows:
1. Double check the installation to make sure that monitor and power supply are
properly installed.
2. Allow 10 minutes for the monitor to warm up once power has been connected.
3. Determine the low flow set point for your monitor. This is the value where
the monitor will first indicate a low flow condition. The red light will be on
for this value. Refer to your industrial hygiene officer for the proper low flow
set point or consult the table below.
4. Adjust your enclosure/fume hood airflow to the low flow set point as
previously determined. The exhaust flow can be lowered by adjusting the
speed control on the FilterMate or by using an adjustable damper on the
exhaust blower. Typical alarm conditions are set at face velocities of 10 to 20
feet per minute below the normal operating conditions due to supply air and
exhaust air fluctuations, as well as room air cross drafts. See note 8 if the low
airflow volume or sash opening cannot be adjusted.
5. Using a properly calibrated thermoanemometer, determine the velocity
through the face of the enclosure by taking a detailed velocity traverse.
Divide the face area into equal increments. One reading per square foot of
face area is normally recommended for an accurate traverse. Compute the
average velocity for this area.
6. If the red light alarm is on, slowly turn the adjustment screw counterclockwise
until the green light is activated. If the green light is on, slowly turn the
adjustment screw clockwise until the red light comes on. Slowly turn the
adjustment screw back until the red light is activated. It is important that
these adjustments be done in small increments, at intervals about 30 seconds
apart to allow for delayed reaction of the alarm itself. The alarm low flow set
point should now be set and the red light activated.
7. Readjust the enclosure airflow to its normal operating levels. The green light
should now be activated. Calibration is now complete.
Enclosure Operating In Flow Speed Alarm Condition Set Point Speed
100 fpm 80 - 90 fpm
80 fpm 60 - 70 fpm
60 fpm 40 - 50 fpm
8. Note: If the low airflow volume or sash opening cannot be adjusted, then a 1/4 to
1/3 of a turn counterclockwise can be adjusted to set the airflow alarm condition
at 10-25% below normal operating levels.
Guardian 500 Alarm Activation
The audio and visual alarm will activate approximately 10-30 seconds after an alarm condition
is detected. To temporarily mute the audible alarm, press and release the test/reset button.
NOTE: After an alarm condition has been detected, the red light will stay on. The
audible alarm will remain muted until airflow returns to normal levels.

Guardian Digital 1000 Calibration
1. Calibrate the airflow monitor according to the instruction manual that
comes with the kit. To successfully calibrate, it will be necessary to
change the face velocity by adjusting the airflow exhaust volume. The
exhaust volume can be adjusted with the speed control on the FilterMate
or by using an adjustable damper on the exhaust blower. Typical
calibration conditions are set at face velocity air sample differences of at
least 20 feet per minute. The airflow monitor is factory set to be
calibrated with a difference of at least 50 fpm and can be changed by
changing the “lower/higher air sample difference”. The following
suggested in flow face velocity speeds are recommended to successfully
calibrate. Typical low air alarms are set 10-20 fpm below operational
speeds. Follow Step 2 below and review the Labconco 1000 Alarm
User’s Manual that comes with the airflow monitor.
Low Air
Alarm
Set Point
40 - 50 fpm 60 fpm 40 - 60 fpm 100 – 120 fpm
60 - 70 fpm 80 fpm 50 - 90 fpm 100 – 150 fpm
80 – 90 fpm 100 fpm 50 – 110 fpm 100 – 170 fpm
2. Go to setup and then CAL CONFIG MENU and change the
“lower/higher air sample difference” to 20 fpm. This will allow you
to successfully calibrate with values of a minimum of 20 fpm
difference.

4. While in CAL CONFIG MENU, adjust the red low air alarm to the
desired setting such as 55 fpm. Then adjust the yellow “CAUTION
or WARNING” to 59 fpm. Then adjust the “CAUTION or
WARNING” air reset to 3 fpm. This sets the alarm condition.
5. To complete the CAL CONFIGURATION, be sure to enter “DONE”.
6. To start the calibration mode, use the Labconco 1000 Manual and
enter “CALIBRATION” mode on the display from the SETUP menu.
7. Follow the instructions on the display and alter the low exhaust
volume with the speed control on the FilterMate or exhaust damper.
Measure the average face velocity and enter the low value on the
display. Be careful not to block the opening. The low exhaust
volume calibration will take about 5 seconds.
8. Now alter the high exhaust volume with the speed control on the
FilterMate or exhaust damper. Measure the average face velocity and
enter the high value on the display. The high value must be at least
20 fpm greater than the low value. The high exhaust volume
calibration will take about 5 seconds.

Product Service 1-800-522-7658
Chapter 6: Maintaining Your Protector Demonstration Hood
9. Be sure to enter “DONE” after successfully completing the low and
high calibration set points.
10. Once calibration is completed, go to “RUN” and hit “ENTER”. The
value should read close to the high calibration set point.
11. To lower the face velocity to the operating point, simply alter the
exhaust volume with the speed control on the FilterMate or exhaust
damper. Then recheck the face velocity with an anemometer to
confirm the display on the digital airflow monitor.
Digital 1000 Alternate Calibration Procedure Constant Volume Conditions
1. To successfully calibrate, it will be necessary to change the face
velocity by opening and closing the enclosure’s sash. The airflow
monitor is factory set to be calibrated with a difference of at least 50
fpm and can be changed by adjusting the “lower/higher air sample
difference”. The in flow face velocity speeds provided in the chart
below are suggested to successfully calibrate the Digital 1000.
2. Before proceeding with calibration, it will first be necessary to
configure the airflow monitor. Go to the setup and then CAL
CONFIG MENU and adjust the “lower/higher air sample difference”
to 10 fpm. This will allow you to successfully calibrate with
minimum difference values of 10 fpm.
3. While in CAL CONFIG MENU, change the “sensor difference” from
10% to 3%.
4. While in CAL CONFIG MENU, adjust the red low alarm to the
desired setting (See the chart below for range and suggested settings).
Then adjust the yellow “CAUTION or WARNING” to the desired
setting (See the chart below for range and suggested settings). Then
adjust the “CAUTION or WARNING” air reset to 3 fpm. This sets
the alarm condition.

5. To complete the CAL CONFIGURATION, be sure to enter “DONE”.
If needed, refer to the Configuration procedure provided on the
following page for additional details.
6. To start the calibration mode, enter “CALIBRATION” mode on the
display from the SETUP menu.
7. Follow the instructions on the display and simulate the low exhaust
volume by fully opening the sash. You may measure the average face
velocity for the low calibration set point or utilize the calculated value
provided in the chart above. The average face velocity for the low set
point is accurately measured by dividing the opening of the enclosure
into equal area grids consisting of at least 9 data collection points and
measuring the velocity at the center of each grid with a calibrated
thermo anemometer. Enter the low value on the display. Be careful
not to block the opening. The low exhaust volume calibration will
take about 5 seconds.
8. Now simulate the high exhaust volume by fully closing the sash to its
normal operating position. Measure the average face velocity for the
high calibration set point to confirm that the source of constant air
volume is providing the desired face velocity for the enclosure. The
average face velocity for the high set point is accurately measured by
dividing the opening of the enclosure into equal area grids consisting
of at least 3 data collection points and measuring the velocity at the
center of each grid with a calibrated thermo anemometer. Enter the
high value set point on the display. The high value must be at least 10
fpm greater than the low value. The high exhaust volume calibration
will take about 5 seconds.
9. Be sure to enter “DONE” after successfully completing the low and
high calibration set points.
10. Once calibration is completed, go to “RUN” and hit “ENTER”. The
value should read close to the high calibration set point.
11. With the sash fully open, the Digital 1000 monitor should go into
“RED LED” low air alarm if successfully calibrated.
