Before you install the vented enclosure, you need to prepare your site for
installation. Carefully examine the location where you intend to install the vented
enclosure. You must be certain that the area is level and of solid construction. In
addition, a dedicated source of electrical power should be located near the
installation site to power the accessory FilterMate Portable Exhauster, balance or
other apparatus. Additionally, a balance should be strategically placed in the lab to
provide efficient workflow.

Carefully read this chapter to learn the requirements for your installation site:

 The support, vibration and movement requirements.
 The temperature variation requirements.
 The humidity and static electricity requirements.
 The location and air current requirements.
 The exhaust and blower requirements.
 The electrical power requirements.
 The space requirements.

Refer to Appendix B: XPert/XVS Dimensions for complete enclosure dimensions.
Refer to Appendix C: XPert/XVS Specifications for complete vented enclosure

electrical and environmental conditions, specifications and requirements.

Support, Vibration and Movement Requirements

At a minimum, the supporting structure usually consists of a base cabinet and
chemically resistant work surface.

XPert and XVS:

 When setting up a chemical station not used for weighing powders, a mobile

stand or cart is allowable.

The ability for analytical balances to accommodate vibration varies with type and
brand. More advanced balances have improved reliability, however in the
preparation of a balance enclosure site, please consider the following:

 Avoid tubular stands or carts that have the potential of moving when touched.
 Work surfaces should be of a thick rigid material that remains stable when

buttons are pressed. An epoxy benchtop or accessory work surface is a
minimum requirement.

 A bench that is rigidly mounted to the floor or fixed to the wall, but not both,

may be appropriate.

 The corners of a building typically have less vibration than the center.
 The bench with the balance enclosure should not contain any vibration-

producing equipment, such as shakers or pumps.

 Marble, granite or epoxy balance tables are generally recommended by the

manufacturers of analytical and microbalances. (See the installation
instructions in Chapter 3).

 Marble slabs within the balance enclosure with dampening pads are also an

effective low cost means of controlling vibration.

Temperature Variation Requirements

XPert:

The extent the balance readings are influenced by temperature variations is a
function of the balance design. Most manufacturers would suggest that a
temperature drift of 1-2°C is generally tolerable. Only validation through your
Operational Qualification protocol can define what is acceptable. To minimize the
potential for temperature variations:

 Never install balances near heating sources such as radiators and hot plates.

Product Service 1-800-522-7658

Chapter 2: Prerequisites

4

 Avoid incandescent lighting of the enclosure where radiant heat produced will

raise temperatures. (See Chapter 7 for adding an accessory fluorescent light kit).

 Do not place the balance and enclosure on a bench that would receive direct

sunlight.

Humidity and Static Electricity Requirements

XPert:

Electrostatics can be troublesome in a balance enclosure. It is important to
understand and, to the extent possible, control static charges. An electrostatic
charged vessel, sample or enclosure can apply forces and lead to errors in
weighing. The repulsion or attraction can be detected with micro, semi micro and
analytical balances. Static charges can also lead to particulates being attracted to
surfaces within the balance enclosure. Containment of harmful powders,
prevention of cross-contamination and clean-up is all enhanced when static
attraction of powders is minimized. The construction of the XPert Balance
Enclosure avoids the use of plastics, which are highly insulative. The advantages
to the glass and epoxy-coated metal construction are twofold.

1. The enclosure does not contribute high electrostatic forces affecting the

precision of the balance.

2. The attraction and ultimate accumulation of powders, (hazardous or

nuisance), are minimized on the inside of the enclosure.

To correct or ensure against electrostatic issues, the following additional measures
may be prescribed to improve weighing operations.

 Maintain a humidity level between 45 and 60%. The ability to sustain this

humidity range can be challenging depending upon the regional climate and
HVAC system.

 Ionizers in various forms (guns, bars and blowers) are effective ways to flood

an area with ions and essentially “neutralize” electrostatic electricity.

Background on Electrostatics or Static Electricity

Electrostatic charges on a surface such as the wall of a balance enclosure are not
created by moving air. Gases do not cause the charge. Impurities within the air
impinging upon surfaces dictate the polarity and magnitude of the charge. The
process, triboelectrification, occurs when the friction of the dust particles contact
the surface and electrons move across the interface.

The ability of a material to become polarized is a property known as permittivity.
On highly insulative materials like acrylic, ions or charged molecules are strongly
bound to the surface by polarization forces. The higher the force, the higher is the
permittivity value of the material. It is suggested that the use of high permittivity
materials, such as plastic be avoided.

Since static electricity is a surface phenomenon, materials can also be classified by
their surface resistivity measured in ohms per square. The table below lists the
surface resistivity of various classes of material.

Surface Resistivity Table

Location and Air Current Requirements

The XPert Balance Enclosure and XVS Ventilation Station both have been
designed to contain hazards by negating typical cross drafts and movements within
the opening. Air movement does not affect most modern balances with draft
shields. However, as a precautionary measure of safety and a higher level of
quality management, it is recommended that the enclosure be placed in such an
area to avoid:

 High traffic areas where walking might cause an air disturbance or be a

nuisance to balance readings.

 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 enclosure has two possible exhaust connections with
either the top exhaust open and the bottom exhaust closed or vise versa. The
bottom exhaust connection is primarily used in installations where the hose or
ductwork needs to be concealed. 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. For house exhaust, only one exhaust
connection is required for the 2' through 6' enclosures and two exhaust connections
are required on the 8' enclosure. Data for the exhaust volume and enclosure static
pressure loss are listed for each enclosure model at face velocities of 60, 80 and
100 fpm. When using the accessory FilterMate Portable Exhausters, it requires the
5" Transition Adapter 3912400, which is sold with the FilterMate. Multiple
FilterMate Portable Exhausters require the airflow to be properly balanced. The 5',
6' and 8' enclosures require two or three FilterMate Portable Exhausters dependent
on face velocity and size.

Proper blower selection can be determined from these exhaust requirements and
the total system static pressure loss. The enclosure must be connected to a
dedicated blower, a house exhaust system or a dedicated filtered exhauster, such as
a Labconco FilterMate. When using multiple FilterMates, the airflow must be
balanced.

Labconco offers accessory remote blowers listed next and in Chapter 7.

Remote Blowers (Roof-Mounted)

A). 1/4 hp direct drive. Corrosion-resistant epoxy-coated steel housing and wheel.
Blower inlet is 6" ID. Outlet dimensions are a rectangular 4.25" x 7.38" OD. See
dimensional data in Chapter 7.

B). 1/4 hp or 1/3 hp belt drive with adjustable sheave to change RPM. Corrosion­resistant epoxy-coated steel housing and wheel. Blower inlet is 10.87" ID. Outlet
dimensions are a rectangular 5.5" x 10" OD. See dimensional data in Chapter 7.

If the enclosure is connected directly to a house exhaust system, an adjustable
damper (or valve) must be installed to control the airflow properly. This is equally
important when a house exhaust system is controlling multiple balance enclosures
or ventilation stations. See Chapter 7 for ordering an accessory adjustable damper.

Electrical Requirements

Standard duplex electrical receptacles should be nearby for connecting the
FilterMate Portable Exhauster, an airflow monitor, accessory fluorescent light or
other equipment, such as a balance for weighing operations. For your convenience
both the accessory FilterMate and accessory fluorescent light kit have auxiliary
outlet receptacles. It is recommended 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 blower exhaust. 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: Enclosure
Dimensions.

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 the Vented Enclosure to the Work Surface

When the enclosure 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 enclosure to the work surface.

Validating the Vented Enclosure

The exhaust damper ductwork, exhaust blower or FilterMate gives you the
flexibility to change the airflow at the sash opening of your enclosure. 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
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 high performance XPert and Protector XVS enclosures.
Refer to Chapter 2 for proper airflow volumes for your particular model.

Your XPert or XVS enclosure 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. For additional validation, Labconco had independent
testing performed to validate the enclosures for
sodium naproxen powder containment. Labconco also had independent ASHRAE
testing performed to validate the enclosures for gas containment. For copies of
these independent validation reports, contact Labconco Customer Service.

NOTE: Face velocity profiles and smoke testing should be performed
frequently per your organizations quality system to ensure safe performance.

High Performance Features

The patented (U.S. Patent No. 6,461,233) XPert Balance Enclosure and Protector
XVS Ventilation Station are designed to meet the needs of the laboratory scientist,
and provide superior containment while conserving energy at OSHA approved “low

flow” velocities as low as 60 feet per minute. The XPert/XVS Enclosure has been

designed to effectively contain toxic, noxious, or other harmful materials when
properly installed and operated. What makes the XPert/XVS Enclosure so unique is
the revolutionary way it directs air into and through the contaminated air chamber.
Labconco engineered the XPert/XVS 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 perforated baffle all work in
concert to produce horizontal airflow patterns that significantly reduce both powder
and chemical concentrations through the work area. These concentrations of

materials are predominantly removed on the “first pass” of airflow through the

chamber resulting in high performance containment.

Figure 4-2

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 airfoil, air continues to pass under the air foil and
through the Clean-Sweep openings. See 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.

Product Service 1-800-522-7658

Chapter 4: High Performance Features and Safety Precautions

21

Figure 4-4

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.

4. Zoned Rear Perforated Baffle directs horizontal laminar air streams to

the three-zoned sections of the perforated baffle in a single pass. The
three-zoned sections have increasingly more airflow at the bottom that
helps form the laminar airflow. This smooth horizontal 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. The zoned
rear perforated baffle may be removed or tilted down for cleaning. See
Figure 4-5.

Figure 4-5

5. Side Entry Air Foils allow turbulence free air to enter the enclosure from

the sides and allow clean air to sweep the interior walls of the enclosure.

6. Ergonomic Slope provides maximum visibility, and comfort reduces glare,

thereby minimizing operator fatigue.

7. Internal Depth of 23" provides necessary depth to support modern

balances and other auxiliary equipment without extending outside the
enclosure or resting on the lower air foil.

8. Two Enclosure Heights and Depths available as standard enclosures in

22.75" or 32". Taller height XVS enclosures are typically used for pipet
operations, titration or taller auxiliary equipment. Unit depth of 29" is
available on 2' through 8' enclosures and 35.5" depth is available on 5', 6',
and 8' enclosures.

9. Unique Flush Sash has a wiping seal to contain contaminants and features

a spring-loaded latch or gas spring for loading auxiliary equipment. The
sash pivots down for normal operation.

10. Electrical Pass through Iris allows electrical cords and data cords to pass

through the back of enclosure without leaving a large hole for contaminants
to escape. The unit 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 XPert/XVS enclosures 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. Exhaust transition
connectors are available for either a 6" OD outside exhaust or a 5" ID hose;
5', 6' and 8' enclosures have multiple exhaust connections. All exhaust
transition connectors are reviewed in Chapters 2 and 3 and accessories
displayed for order in Chapter 7.

13. Accessory Guardian™ Airflow Monitors continuously monitor airflow.

An audio/visual alarm alerts the user to low airflow conditions. The
Guardian™ 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 detailed
information, 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

XPert/XVS enclosures when used with an exhaust damper. See Chapters 2,
3 and 7.

16. Accessory FilterMate Portable Exhauster provides up to 280 cfm for

HEPA filtration or up to 220 cfm for combination HEPA/Carbon filtration
when connected to XPert/XVS enclosures. Multiple FilterMates must be
balanced and can be used on 5', 6' and 8' units with multiple exhaust

Safety Precautions

Although the enclosure has been engineered to maintain optimum operator
safety, caution should always be used while working. Prior to using the
enclosure, check to make sure that the exhaust blower is operating and that
air is entering the enclosure 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 enclosure 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 enclosure 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 enclosure as possible. It is
best to keep all powders, chemicals and apparatus inside the lower air foil of
the enclosure.

Do not work with chemicals in this enclosure without the exhaust system
running.

Perchloric acid use in this enclosure is prohibited.
High-level radioisotope materials are prohibited in this enclosure.
Avoid cross drafts and limit traffic in front of the enclosure. Air disturbances

created may draw contaminants out of the enclosure.
A qualified certification technician should test the XPert Balance Enclosure

or Protector XVS Ventilation Station before it is initially used. The enclosure
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 enclosure.
Proper operation of the enclosure depends largely upon its location and the

operator’s work habits. Consult the references in Appendix D.

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.

8. Note: If the low airflow volume or sash opening cannot be adjusted, then a 1/4 to 1/3

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.

Locate the elbow, locknut, and washer and install it in the 1.19" dia. hole
per Figure 6-5 and Figure 6-6. The enclosure baffle pivots down to install
the elbow, washer and locknut.

3. Cut the 1" hose supplied with the kit to 10.5" approximate length and

install it between the airflow sensor and the elbow.

4. Secure the Guardian Digital alarm to the enclosure with double stick tape

as shown in Figure 6-7. The airway passage between the alarm module and
the enclosure is now complete.

5. Locate the metal hose cover and install with double stick tape per Figure 6-6.

6. Locate the power supply transformer. One end should already be connected

to the two-pin connector labeled 15 VDC on the back of the alarm module
and through the strain relief bushing. If disconnected, then reconnect to
power the airflow monitor. Plug the 115V power supply into a standard
115V duplex receptacle, the back of the accessory FilterMate portable
exhauster or the back of the accessory light. For 230V, plug into a standard
receptacle with your specific outlet plug. (It is recommended that the

airflow monitor be connected directly to the FilterMate switched
auxiliary outlet so the airflow monitor is powered at the same time.)

7. Installation is now complete.

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.

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.

3. While in CAL CONFIG MENU, change the “sensor difference” from 10%

to 3%.

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.

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 inflow 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.

* Because of airflow fluctuations in a typical laboratory environment Labconco suggests

setting the “RED LED” low alarm set point to 20% below the enclosure’s operating speed.

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 calibration set

point at the normal sash operating position. 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 3-9 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 calibration set point by blocking the sash opening

by ¾ (with cardboard) for the high average speed. 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 low calibration set point.

11. With the sash fully pivoted open, the Digital 1000 monitor should go into

“RED LED” low air alarm if successfully calibrated.

9. Utility Shelf Kit and Holders

Labconco offers a utility shelf kit part number 3925000 consisting of three
shelves to hold items inside the enclosure. One shelf may be used for the
printer, one shelf for spatulas and weigh brushes, and one miscellaneous shelf.
The shelves hang from slots in the rear baffle. The printer shelf can be
inverted and rest on top of the enclosure as an alternate location.

The 3927700 Bottle Holder holds a squirt bottle and has a 3" diameter opening.
The 3927800 Tissue Holder permits tissues to be dispensed from the bottom.

10. Hoses, Hose Clamps, and Hose Kits

Provides alternatives for ducting.

11. Prefilter Kits (Nuisance Powders Only)

Pre-filter kits are not required for potent compounds and are rarely used unless
otherwise specified. Pre-filter kits are primarily used for nuisance powder
applications only and typically with large quantities of powder. Pre-filter
material is 0.4" thick polyester designed to trap about 80-90% of nuisance
powders to preserve HEPA Filter life. Pre-filter kits are located before the
HEPA Filter and behind the rear baffle.

Environmental Conditions

 Indoor use only.
 Maximum altitude: 6562 feet (2000 meters).
 Ambient temperature range: 41° to 104°F (5° to 40°C).
 Maximum relative humidity: 80% for temperatures up to 88°F (31°C),

decreasing linearly to 50% relative humidity at 104°F (40°C).

 Main supply voltage fluctuations not to exceed ±10% of the nominal

voltage.

 Transient over-voltages according to Installation Categories II (Over-

voltage 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.

Chemir Analytical Services conducted balance stability tests on the XPert Filtered
Balance System mounted on a Solid Epoxy Work Surface. No marble slab was
used. The enclosure was tested while operating at three face velocities – 0, 78 fpm
(factory setting), and 100 fpm. Samples of 5 mg, 50 mg and 100 mg were weighed
on an analytical balance located inside the enclosure. Test results were excellent
and confirm that the XPert Filtered Balance System, including its built-in blower
and the airflow through the enclosure, caused no detectable instability to the
balance. The weight of each sample was stable to five decimal places.

Listed next are some hints on balance stability.

1. Balance is not calibrated (or at least not recently) – All balances should be

calibrated at least annually or after they have been shipped or moved
around frequently. If the balance has just been moved around the lab, it
probably will not require recalibration. Most new balances have an internal
mechanism that compensates for drift and vibration. If in doubt, schedule
recalibration.

2. Shield is not tight on the balance – If the balance shield is loose, air can get

into the weighing chamber and cause fluctuation in sensitive weigh
applications. In other words, air can get into the balance and cause the
weigh plate to fluctuate. The best way to address the problem is to have
the balance servicer fix the balance shield.

3. There is no shield on the balance – Sometimes open balances without

shields fluctuate. Try running the ventilated balance enclosure at slower
speeds such as 60-70 feet per minute, getting a shield placed around the
balance, or using a balance with a tight shield.
