Introduction

Congratulations on your purchase of a Labconco XPert® Filtered Balance System,
XPert® Filtered Balance Station, or RXPert™ Filtered Balance System. Your
enclosure provides personnel protection through superior containment while
conserving energy at OSHA approved velocities as low as 60 feet per minute. It is
the result of Labconco’s more than 50 years of experience in manufacturing fume
hoods and more than 30 years of experience in manufacturing filtered enclosures.

These enclosures will effectively contain toxic or noxious particulates when
properly installed and operated. Each enclosure uses a single HEPA filter, which
is rated at least 99.99% efficient for 0.3-micron particles. Some RXPert enclosures
use a second redundant HEPA filter. Additionally, an accessory Odor Control
carbon filter may be added to adsorb nuisance odors from organic vapors,
formaldehyde or ammonia and amines. The XPert filtered enclosures offer many
unique features to enhance safety, performance, and energy savings. To take full
advantage of them, please acquaint yourself with this manual and keep it handy for
future reference. If you are unfamiliar with how high performance HEPA filtered
enclosures operate, please review Chapter 4: High Performance Features and
Safety Precautions before you begin working in the enclosure. Even if you are an
experienced user, please review Chapter 5: Using Your HEPA Filtered Enclosure,
which describes the XPert features so that you can use the filtered enclosure
efficiently. For weighing hazardous and nuisance powders, Labconco
recommends the purchase of the XPert Filtered Balance System or XPert Filtered
Balance Station. Both XPert filtered enclosures include a true bag-in/bag-out
HEPA filter to properly protect personnel during filter changing operations. With
recent changes for non-sterile compounding to meet USP <800> requirements,
consult with Labconco product specialists concerning RXPerts with double HEPA
filtration or RXPerts with single HEPA filtration ducted to the outside. See chart
that follows next and contact Labconco for additional ordering information.

Chapter 2:
Prerequisites

Before you install the filtered enclosure, you need to prepare your site for
installation. 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 filtered enclosure, balance and other apparatus.
Additionally, the enclosure 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: Dimensions for complete enclosure dimensions.
Refer to Appendix C: Specifications for complete filtered 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 work
surface.

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

 Avoid tubular stands or mobile benches that have the potential of moving

when touched.
 Work surfaces should be of a thick rigid material that remains stable when

buttons are pressed.

Chapter 2: Prerequisites

Product Service 1-800-522-7658

 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 with dampening pads placed within the enclosure are also an

effective low cost means of controlling vibration.

 The balance should be calibrated and verified at least annually; for best

results, the balance should be calibrated inside the enclosure while running at
the desired face velocity.

Temperature Variation Requirements

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

sunlight.

Humidity and Static Electricity Requirements

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 enhanced when static attraction
of powders is minimized. The construction of the XPert Filtered Balance System
and XPert Filtered Balance Station avoid 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.

Chapter 2: Prerequisites

Product Service 1-800-522-7658

5

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 dust particles contact the surface,
creating friction 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 by balance manufacturers 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.

Location and Air Current Requirements

The XPert Filtered Enclosures have been designed to contain hazards by negating
typical cross drafts and turbulence within the opening. Air movement does not
affect most modern balances with draft shields. However, as a precautionary
safety measure and a higher level of quality management, it is recommended that
the enclosure be placed in 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.

Do not position the unit so that it is difficult to operate the main
disconnect device.

Ne placez pas l'appareil de sorte qu'il est difficile de faire
fonctionner le dispositif principal de déconnexion.

Exhaust and Blower Requirements

The XPert Filtered Balance System uses an integral motorized impeller to draw
room air past the operator and through the enclosure. This contaminated air is then
pushed through the HEPA filter. The HEPA-filtered exhaust air is then forced out
the top of the enclosure. An optional carbon filter may be installed on the
downstream side of the HEPA filter to protect against nuisance odors.

The HEPA-filtered exhaust air can be recirculated into the laboratory or exhausted
outside with the addition of the Canopy Exhaust Connection and remote blower
listed in Chapter 7. Electrical connections are covered in Chapter 2 for this
configuration.

The XPert Filtered Balance Station does not include the motorized impeller and
must be exhausted to the outside by a remote blower. The XPert Filtered Balance
Station remote blower may be switched from the blower switch on the enclosure.
See Electrical Requirements in Chapter 2, and Electrical Supply Connections in
Chapter 3. Only one 6" exhaust connection is required for the 2', 3', or 4' XPert
Filtered Balance Stations to exhaust to the outside. Only one 10" exhaust
connection is required for the 5' and 6' XPert Filtered Balance Stations.

Data for the exhaust volume, noise pressure and enclosure static pressure loss are
listed for each filtered enclosure model at face velocities of 60, 80, and 100 fpm.
Balances typically work best between 60-90 fpm with the balance shield closed
tightly.

Proper blower selection can be determined from these exhaust requirements and the total
system static pressure loss. For outside exhaust, the enclosure must be connected to either a
dedicated blower or a house exhaust system. Labconco offers accessory remote blowers
listed in Chapter 7. Contact Labconco for blower sizing assistance.

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 filtered enclosures. See Chapter 7 for accessory
adjustable damper ordering information.

Electrical Requirements

Standard duplex electrical receptacles should be nearby for connecting the filtered
enclosure, or other equipment, such as a balance for weighing operations. The
enclosures include iris pass-thru to allow electrical cords through the back of the
enclosure without leaving a large hole for contaminants to escape.

XPert System

There is no provision for controlling a remote blower for exhausting air from the
XPert Systems. One way to do this, however, is to have a certified electrician connect
a wall mounted switch receptacle nearby so that the switch controls both the remote
blower and the receptacle. The power cord for the XPert System is then plugged into
this receptacle.

XPert Station

The remote blower for the XPert Filtered Balance Station may be connected to the
blower switch on the enclosure. The blower switch is connected to a relay whose
wires are terminated in the junction box behind the front panel. We recommend a
maximum amperage of 6 for this circuit to the remote blower. Connect the blower
wires inside the junction box to the remote blower per local electrical codes.

Space Requirements

The dimensions for the different models are shown in Appendix B: Dimensions.

Installation of HEPA Filters and Accessory Odor

Control Carbon Filters

HEPA Filters

HEPA filters are shipped installed with the gasket on the downstream side. The
HEPA filters are leak checked at Labconco. A second leak check is recommended
before using the enclosure and at least annually thereafter. Consult your Safety
Officer and Chapter 6 for the HEPA Filter Leak Test and HEPA Filter Bag-In/Bag­Out Procedure. See Figure 4-2 for HEPA filter location, HEPA filter gasket, filter
clamp bolts, and bag-in/bag-out flange. The XPert enclosures have a true bag­in/bag-out HEPA filter to safely dispose of the filter. All seams upstream of the
HEPA filter are jacketed by negative pressure. This intrinsically safe design
ensures containment.

Carbon Filters (Accessory for Odor Control only)

For carbon filter installation, first remove the upper perforated cover, secured by
Phillips head screws, on the top of the enclosure. See Figures 4-1 and 4-2 for
location of the upper perforated cover. See Chapter 7 for a list of available carbon
filters. All carbon filters are simply gravity installed with the gasket side down
and down stream on the exhaust side of the HEPA filter. Install the correct carbon
filter for the application.

Connecting the Electrical Supply Source to the
Filtered Enclosure

115V Models

Simply connect the 115V power cord supplied to the IEC electrical supply plug on
the back of the enclosure. If using at 50 Hz operations, blower performance
maximum airflow will be reduced by 17%.

For the remote blower used for XPert Stations, follow the wiring diagram on the
enclosure and wire the blower wires in the electrical junction box located behind the
front panel. These wires are switched by the electrical relay via the blower switch.
The maximum circuit load for the electrical relay is 6 amps. Only the remote blower
wiring is connected inside the electrical junction box. The lights and airflow monitor
are powered from a standard duplex electrical receptacle located nearby for connecting
the power cord. All wiring for the XPert Filtered Balance Station should be performed
by a licensed electrician and conform to local codes. In most cases, the XPert Filtered
Balance Station will require the use of shielded conduit to protect the wiring.

Set the Face Velocity with the Speed Control

Adjustment

XPert Filtered Balance System Only

For XPert Filtered Balance Systems, adjustment of the speed control gives the
correct face velocity and is located behind the front panel. The face velocity
should be adjusted from 60 to 100 fpm for weighing operations. (Consult your
Safety Officer for airflow recommendations for your application). Containment is
maximized at a setting within this range. Working at the lowest face velocity
appropriate for the application will give the quietest operation. Face velocity
measurements are made using an anemometer. An electric anemometer can be
obtained from your laboratory supply dealer. Face velocity measurements should
be taken in accordance with the Industrial Ventilation Manual. Using a small
Phillips screwdriver, adjust the speed control to give the required face velocity.
See Figures 6-1 and 6-2 in Chapter 6 to locate the speed control. The face velocity
is increased by turning the speed control counter clockwise and clockwise to
decrease face velocity.

Validating the Vented Enclosure

To determine the actual face velocity at the sash opening, airflow velocity readings
are taken. This should be done across the sash opening of the enclosure in
accordance with the Industrial Ventilation Manual. (See Appendix E) 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. Refer to Chapter 2 for proper airflow volumes for your particular model.

The XPert enclosures have been tested at Labconco’s airflow test facility 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 particulate powder validation, Labconco had
containment testing performed to validate the enclosures for sodium naproxen

powders. The XPert HEPA filtered enclosures demonstrated excellent containment
when used by an operator using excellent technique and good containment when used
by an operator using marginal technique. While no enclosure can compensate for
improper technique, these tests confirm that the XPert HEPA Filtered Enclosures
provide a safe working environment. For particulate powder and gas containment,
Labconco performed extensive testing to validate the enclosures. For balance
stability, Labconco conducted tests with a built-in blower and without a marble
surface; test results were excellent at 78 fpm and 100 fpm, confirming no detectable
instability with the five decimal place balance. For copies of these validation reports,
contact Labconco Customer Service.

The XPert enclosures were also subjected to Biological Containment testing, using
a modified Personnel Protection Test, as described in NSF/ANSI Standard Number

49. An aerosol challenge of approximately 5 x 108 spores of Bacillus subtilus var
Niger were released in the enclosure and appropriate air sampling equipment
established the number of spores that escaped through the sash opening. Each size
enclosure was tested three times. All sizes of the enclosure were tested at 75 FPM
inflow and typically 1 or less than one spore escaped from the enclosure during
each of the tests.

NOTE: Face velocity profiles and smoke testing should be

performed frequently per your organization’s quality system to

ensure safe performance.

Sealing the Filtered Enclosure to the Work Surface

When the filtered enclosure has been set in place, ducted, (if necessary), and wired,
it must 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 filtered
enclosure to the work surface. This seal also provides additional rigidity.

High Performance Features and

Safety Precautions

High Performance Features

The patented1 XPert Filtered Balance System and XPert Filtered Balance 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 filtered enclosures have been tested to effectively
contain toxic and noxious materials when properly installed and operated. What
makes the filtered enclosures so unique is the revolutionary way they direct air into
and through the contaminated air chamber. Labconco engineered the filtered
enclosures 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 powder, chemical and
particulate 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. The
plenum and the HEPA filter are jacketed by negative pressure. Should a leak
occur in the filter gasket or the plenum, the contaminated air is recaptured and
refiltered.

The XPert Filtered Balance System and XPert Filtered Balance Station include a
true bag-in/bag-out HEPA filter disposal system to protect the worker from contact
with hazardous powders and particulates. Users of both products are encouraged
to routinely check airflow with the use of the airflow monitor.

1. Aerodynamic Clean-Sweep™ Air Foil has a unique shape that allows air

to sweep the work surface for maximum containment. The Clean-Sweep™
openings create a constant protective barrier from contaminants. 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 Figures 4-1 and 4-3.

2. Containment-Enhancing Upper Sash Foil includes an open air passage

directly atop the sash foil to bleed air into the hood chamber and direct
chemical, powder and particulate materials away from the sash opening.
The radiused sash foil sweeps airflow into the hood with minimal
turbulence. See Figures 4-1 and 4-4.

Figure 4-3

Figure 4-4

Chapter 4: Performance Features and Safety Precautions

Product Service 1-800-522-7658

3. Upper Dilution Air Supply provides bypass air from above the work area.

This feature constantly bathes the inside of the sash with clean air and
reduces powders, particulate materials 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.
The upper dilution air supply also reduces stagnant pockets of air in the
upper interior. See Figure 4-2.

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

the three-zoned sections of the perforated baffle. The three-zoned sections
have increasingly more open area at the bottom that help form laminar
airflow. This minimizes the potential for air to roll forward preventing
contaminants from moving toward the sash opening. The majority of
contaminants are highly diluted, captured and removed on the first pass
through the enclosure. Rear perforated baffle may be tilted or removed for
ease in cleaning. See Figures 4-1 and 4-2.

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.
See Figures 4-1 and 4-2.

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

thereby minimizing operator fatigue. See Figure 4-1.

7. Internal Depth of 23" or 30" and 22.8" or 32" Interior Height provides

necessary depth and height to support modern balances and other auxiliary
equipment without extending outside the enclosure or resting on the lower air
foil. See Figure 4-1. The 2' and 3' sizes are available with 23" internal depth
and 22.8" interior height. The 4' sizes are available in 22.8" or 32" interior
height and are available with 23" or 30" interior depth. The 5' and 6' sizes
have standard 32" interior height and are available with 30" interior depth.

8. Safety Glass Sash has a wiping seal to contain contaminants and features a

spring-loaded latch to secure sash open for loading and cleaning. The sash
must be down for normal operation. See Figure 4-1. The 5' and 6' units
utilize a gas spring assist in place of the latch.

9. Utility Ports with Iris allows electrical cords and data cords to pass

through the back of enclosure without leaving a large hole for contaminants
to escape. The enclosure ships with solid plugs. Iris plugs are included
with the User’s Manual. See Figure 4-1 and 4-2.

10. Accessory Guardian Airflow Monitor or Guardian™ 1000 Digital

Airflow 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. Both airflow
monitors are available options on all XPert models. See Figure 4-1 and 4-2.

11. Inherently Safe Impeller has a negative pressure plenum that surrounds

the positive pressure impeller so that if a leak should occur, the unfiltered
air is captured and refiltered. See Figure 4-2.

Chapter 4: Performance Features and Safety Precautions

Product Service 1-800-522-7658

25

12. Vibration-Isolated Motorized Impeller has vibration isolation supports,

which eliminates transfer of vibration to the work surface. This is
extremely useful in weighing operations with precision balances. The
impeller wheel is also dynamically balanced. See Figure 4-2.

13. Speed Control regulates the speed of the motorized impeller and is used

by the certifier to validate and adjust the inflow velocity. Located behind
the front panel. See Figure 4-2.

14. Space-Saving Design increases effective laboratory workspace, because

the impeller and HEPA filter are contained within the enclosure, a separate
filtered blower module is not required. See Figure 4-1

15. Fluorescent Lamp is located above the work area, out of contact with

contaminated air. A safety glass window beneath the lamp distributes the
light evenly across the work surface. See Figure 4-1.

16. Filter System Pressure Gauge indicates the total system pressure across

the HEPA filter and pressurized plenum to help predict HEPA filter
loading. See Figure 4-1.

17. Filter Clamping Bolt evenly seals the HEPA filter to the frame of the

enclosure. See Figure 4-1 and 4-2.

18. Sash. The sash is constructed of 1/4 inch tempered safety glass. It pivots

up for loading and cleaning. See Figure 4-1

19. Control Panel. The control panel, which is located above the sash,

contains the filter system pressure gauge, control switches and the
electronics. See Figure 4-1.

20. HEPA (High Efficiency Particulate Air) Filter is rated to remove

99.99% of all particles 0.3 micron in size. See Figure 4-2. HEPA filters
listed in Chapter 3 and 7.

21. Lamp Ballast (Not Shown) for the fluorescent lamp is located behind the

control panel.

22. Accessory Work Surface (not shown) is contoured to fit the dimensions of

the enclosures to contain spills.

23. XPert Filtered Balance Station Exhaust Collar (Not shown) provides a

6" (2', 3' and 4') or 10" (5' and 6') diameter transition to a remote blower or
house exhaust system. See Figure 3-2 in Chapter 3.

24. Accessory Odor Control Carbon Filters are available for nuisance odor

control. Accessory carbon filters are designed to remove trace amounts of
noxious fumes; capacity is not adequate to remove continuous fume
generation. The carbon filters are supported above the HEPA filter and the
gasket side is down and compressed by the weight of the carbon filter.
Carbon filters are listed in Chapter 3 and 7. See Figure 4-2.

25. Accessory Thimble Exhaust Connection is available to duct integral

blower models including the XPert Filtered Balance System to the outside.
The Thimble Exhaust Connection allows the operator additional protection

from hazardous particulates, fumes or vapors and should also be used if the
carbon filter capacity is not adequate. Each Canopy Exhaust Connection
includes an epoxy-coated steel exhaust transition adapter designed for 6"
diameter nominal duct on 2', 3' and 4' sizes. The 5' and 6' sizes use 10"
nominal duct. See figure 3-3 in Chapter 3 and figure B-3 in appendix B.

26. Upper Diffuser Screen provides protection for the HEPA Filter and

(LED) airflow sensor. See Figure 4-1 and 4-2.

27. HEPA Filter Access Port to access HEPA filter during filter changing

procedures. For harmful powders and particulates, the true bag-in/bag-out
procedure is used to properly dispose of the contaminated HEPA filter. See
Figure 4-2.

28. Utility Shelves (not shown) allow the user to hold utensils and printers on

shelves inside the enclosure. See Chapter 7.

Safety Precautions

1. 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 to a problem with airflow.

2. Use good housekeeping in the enclosure at all times. Clean up spills

immediately. Periodically clean enclosure interior.

3. 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 objects 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.

4. 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).

5. Always work with your hands as far back into the enclosure as possible.

Keep all powders, chemicals and apparatus inside the lower air foil of the
enclosure.

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

7. Perchloric acid use in this enclosure is prohibited.

8. High-level radioisotope materials are prohibited in this enclosure. Consult

your Safety Officer.

9. Avoid cross drafts and limit traffic in front of the enclosure. Air

disturbances created may draw contaminants out of the enclosure.

10. A qualified certification technician should test the enclosure before it is

initially used. The enclosure should be validated whenever it is relocated.

Chapter 4: Performance Features and Safety Precautions

Product Service 1-800-522-7658

27

11. The use of safety goggles, protective clothing, gloves and any other

personal protective equipment recommended by your safety officer should
be used.

12. The sash must remain in the down position while using the enclosure.

13. Proper performance of the enclosure depends largely upon its location and

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

14. The enclosure should be recertified whenever it is serviced or at least

annually thereafter.

15. The HEPA filter provides personnel and environmental protection from

particulate matter. Because room air is drawn over the work surface during
operation, this enclosure should not be used for operations requiring
product protection from environmental contamination.

16. Avoid the use of flammable gases or solvents in the enclosure if possible.

Care must be taken to ensure against the concentration of flammable or
explosive gases or vapors. Use of an open flame should be avoided in the
enclosure. Open flames may disrupt the airflow patterns in the cabinet,

burn the HEPA filter and damage the filter’s adhesive. Gases under high

pressure should not be used in the enclosure as they may disrupt the airflow
patterns of the cabinet.

17. HEPA filters are only effective for entrapment of particulate matter.

Manipulations that generate gases or vapors from toxic chemicals or
radionuclides, must be evaluated carefully from the standpoint of buildup
to dangerous levels, the decontamination of the enclosure and compliance
with applicable regulations.

18. The surface of the HEPA filter is fragile and should not be touched. Care

must be taken to avoid puncturing the HEPA filter during installation or
normal operation. If you suspect that a HEPA filter has been damaged DO
NOT use the enclosure; contact a local certification agency or Labconco.

19. The HEPA filter in the enclosure will gradually accumulate airborne

particulate matter from the room and from work performed in the
enclosure. The rate of accumulation will depend upon the cleanliness of
the room air, the amount of time the enclosure is operating and the nature
of work being done in the enclosure. With normal usage, the HEPA filters
will last two to five years before requiring replacement.

20. Ensure that the filtered enclosure is connected to an 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 filtered enclosure from
electrical service.

21. Use of an open flame must be avoided with the enclosure. Open flames

may disrupt the airflow patterns in the enclosure and cause a fire hazard
with volatile solvents.

Chapter 4: Performance Features and Safety Precautions

Product Service 1-800-522-7658

28

22. Increase the face velocity by adjusting the speed control of the motorized

impeller on the XPert Filtered Balance System or change the HEPA filter
when the face velocity falls below acceptable limits established by your
Safety Officer.

23. Exhaust carbon filters and HEPA filters are disposed as hazardous waste.

The user is responsible for recording the chemicals adsorbed or treated by
the filters and disposing properly. HEPA filters should be disposed using
the disposal bag on XPert enclosures.

24. Ensure only trained operators use the enclosure. New users should review

the User’s Manual and become familiar with the operation of the enclosure.

25. If the filtered enclosure is to be used in a confined space, make sure the

space is well ventilated and the concentration of toxic contaminants cannot
accumulate greater than the TWA.

26. Proper operation of the enclosure depends largely upon the enclosure

location and the operator’s work habits. The enclosure should be located

away from traffic patterns, doors, fans, ventilation registers, fume hoods,
and any other air-handling device that could disrupt its airflow patterns.
Consult Chapter 2: Prerequisites and Chapter 3: Getting Started sections of
this manual for further details.

27. Only powders and particulates removed by HEPA filters and trace

chemicals, which can be safely adsorbed and treated with specific carbon
based filters are appropriate for use in this enclosure.

28. The warning properties (i.e., odor, taste) of the volatile organic compounds

or other material being used in the enclosure must be adequate to provide
an early indication that the carbon filter may be saturated or inadequate.
Contact Labconco for help with chemical assessment.

29. Use the smallest possible quantity of chemical(s) within the enclosure and

never exceed the amount, which can be effectively adsorbed by the Odor
Control carbon filter before breakthrough.

30. For weighing procedures, adjust face velocity between 60 and 100 FPM for

effective operation.

31. Leave the blower on for at least one minute after work in the enclosure has

been completed.

32. If a chemical, powder or particulates are spilled on the work surface, DO

NOT switch off the blower until all traces have been removed.

33. Tag enclosures with appropriate warning, if filters have been removed for service.

34. If the blower fails during use, processes should cease and the area should

be vacated and ventilated.

35. Always refer to the NIOSH Pocket Guide to Chemical Hazards before

proceeding. For additional help with filter and chemical selection contact

tightly and the enclosure set between 60-90 fpm.

 Arrange for minimal disruptions, such as room traffic or entry into the

room while the enclosure is in use.

Start-up

 Turn on exhaust system and accessory light.
 Only raise the sash for loading and cleaning.
 Check the baffle air slots for obstructions.
 Allow the enclosure to operate unobstructed for 1 minute.
 Wear a long sleeved lab coat and rubber gloves. Use protective eyewear.

Wear a protective mask if appropriate. Consult your Safety Officer for
additional personal protective equipment recommendations.

Chapter 5: Using Your Filtered Enclosure

Product Service 1-800-522-7658

30

Loading Materials and Equipment

 Load only the materials required for the procedure. Do not overload the

enclosure.

 Do not obstruct the air foil, or rear baffle slots.
 Large objects should not be placed close together and should be elevated

above the work surface to permit airflow to sweep under the equipment.

 After loading, wait one minute to purge airborne contaminants from the

work area.

Work Techniques

 Keep all materials inside the lower air foil, 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 enclosure.

Final Purging

 Upon completion of work, the enclosure should be allowed to operate for

two to three minutes undisturbed, to purge airborne contaminants from the
work area before shutting down the blower.

Unloading Materials and Equipment

 Objects in contact with contaminated material should be surface

decontaminated before removal from the enclosure.

 All open trays, weigh vessels or containers should be covered before being

removed from the enclosure.

Shutdown

 Turn off the exhaust system and light.

Suitable Applications

NIOSH (National Institute for Occupational Safety and Health, USA) has
established guidelines for chemical cartridge and HEPA filtered respirators.
Suitable applications for the filtered enclosures are based on these guidelines. As
with respirators, chemical contaminants are adsorbed or treated by carbon;
particulates, powders and biohazardous materials are filtered by the HEPA filter
before air is returned to the room. Biohazardous materials or other hazardous
solids can be used with the HEPA filtered enclosure as long as appropriate
decontamination occurs before filter changing operations. See Chapter 6 for
decontamination procedures.

Listed below are suitable applications for HEPA filters and accessory Odor
Control Carbon Filters.

Chapter 5: Using Your Filtered Enclosure

Product Service 1-800-522-7658

31

HEPA Filter Applications, Suitability and Guidelines

 Biohazardous materials and hazardous solids to protect only the operator and

the surrounding environment.

 Weighing of powders.
 Release of particulates using a HEPA filter.
 Powder or particulate procedures traditionally performed on an open bench.
 The HEPA filtered enclosure provides personal and environmental protection

from particulate matter, hazardous powders and biohazardous materials.
Because room air is drawn through the enclosure during operation, this
enclosure should not be used for operations requiring sample protection from
environmental contamination.

 HEPA filters are only effective for entrapment of particulate matter, hazardous

powders and biohazardous materials. Manipulations that generate gases or
vapors, i.e., toxic chemicals or radionuclides, require the use of a HEPA and
carbon filter in combination. Otherwise the enclosure should be ducted to the
outside. The surface of the HEPA filter is fragile and should not be touched.
Care must be taken to avoid puncturing the HEPA filter during installation. If
you suspect that a HEPA filter has been damaged, DO NOT use the enclosure.
See Chapter 6 for replacing the HEPA Filter or using a Bag-In/Bag-Out
Disposal Bag.

 The HEPA filter will gradually accumulate airborne particulate matter from

the room and from work performed in the enclosure. The rate of accumulation
will depend upon the cleanliness of the room air, the amount of time the
enclosure is operating, and the nature of work being done. With normal
usage, the HEPA filters will last two to five years before requiring
replacement.

 Each filtered enclosure is provided with a HEPA filter. For powders and

particulates follow the HEPA Filter Bag-In/Bag-Out procedure in Chapter 6
for disposal instructions. For biohazardous materials, follow the
Decontamination Procedure in Chapter 6 for disposal instructions.

Odor Control Carbon Filter Applications (sold as an accessory)

 Release of low concentrations of vapors effectively adsorbed or treated in

carbon based filters.

 Treatment of low-level carcinogens or suspected carcinogens. (See Chemical

Carcinogens in Chapter 5)

 Procedures that may have traditionally been done on the open bench (low

levels only).

 Odoriferous chemicals that are an unpleasant nuisance.

Chapter 5: Using Your Filtered Enclosure

Product Service 1-800-522-7658

32

Other applications, not fitting the above guidelines, would be better suited with the
exhaust ducted to the outside. The exhaust connection kit (See Chapter 3 and
Chapter 7) can be added to the XPert Filtered Balance System for ducting to the
outside. Additionally, the XPert Filtered Balance Station is factory prepared to be
connected to a remote blower, or house exhaust system for ducting to the outside.
Labconco also manufactures fume hoods and Class II Biological Safety Cabinets
for exhausting to the outside. Consult Labconco product specialist for additional
information.

Appropriate Chemicals for Odor Control Carbon

Filters

Below is a general set of rules to determine appropriateness of chemical usage.
Selected organic chemicals considered to be occupational carcinogens by NIOSH

– National Institute for Occupational Safety and Health/Mine Safety and Health
Administration. (U.S.A.) can be used in the filtered enclosure with carbon filters
under rigid restrictions. See separate discussion on carcinogens for special
instructions. Organics must have time weighted exposure limits TWA (Time
Weighed Average) of 1 PPM or greater.
Chemicals must have a detectable odor at concentrations below the TWA for the
chemical.

Chemicals must be designated by NIOSH (National Institute for Occupational
Safety and Health/Mine Safety and Health Administration) guidelines as
acceptable for use with chemical cartridge-type respirators (the exception is
formaldehyde and ammonia/amines, which used impregnated carbon).

Chemicals not listed by NIOSH in the Pocket Guide must be approved by
Labconco Product Specialist (or Engineering). Inlet concentration must never
exceed the IDLH (Immediately Dangerous to Life and Health) concentrations.

Chemicals having a recommendation by NIOSH of at least “Escape GMFOV”

(Gas Mask Full-Face Respirator).
When evaporating a mixture of chemicals, the chemical having the lowest TWA

will be used to determine if the mixture meets the guidelines.
Call a Labconco Product Specialist at 1-800-821-5525 for assistance in chemical
appropriateness.

Hazardous Misapplications for Odor Control Carbon

Filters with Volatile Chemicals

There is one scenario where the accessory carbon filter misapplication would be a
part of a hazardous condition. If the user continues to operate the enclosure with
any of the following conditions present a potentially hazardous condition will
exist:

Chapter 5: Using Your Filtered Enclosure

Product Service 1-800-522-7658

33

1. The inlet concentration of vapors is greater than the TWA.

2. The carbon filter becomes saturated.

3. The ventilation of the room is insufficient to dilute the exhaust of the

enclosure to below the TWA for the chemical.

When the inlet concentration is greater than the TWA, extra measures must be
taken to monitor the filter and number of room air exchanges.

Chemical Carcinogen Use with Odor Control Carbon

Filters

Selected carcinogens may be used safely with Odor Control carbon filters under
the following restrictions.

The use of a vented fume hood or ventilated enclosure with
ducting to the outside is always the preferred method when
working with carcinogens. The Odor Control carbon filters
should only be used, as a last resort when venting to the outside is
not an option. Another option is the use of the XPert Filtered
Balance Station, which uses a remote blower.

The potential carcinogens are listed in the NIOSH Pocket Guide to Chemical

Hazards as “Ca.” Each potential carcinogen must have a TWA of 1 or greater;

have minimum respirator recommendation of Escape GMFOV, and an odor
threshold significantly lower than the TWA for the chemical. The inlet
concentration or the evaporation rate of the chemical must never exceed the TWA
for the chemical.

Consult a Labconco Technical Specialist for estimated saturation life. See Chapter
6 for an example of estimating saturation life. Another source is the Labconco
chemical guide for carbon-filtered enclosures.

Prohibited Acid Use

The XPert Filtered Balance System and RXPert motorized impeller cannot be
exposed to heavy acid use. Where applications require the use of heavy acids, a
separate ventilated enclosure or vented fume hood should be used with a remote
blower ducted to the outside. No exceptions are permitted, as the impeller life
span will be limited with acid use. Accessory odor control acid-sulfur filters are
only used with very light duty acids.

LOW-LEVEL ACIDS CAN BE USED WITH THE XPERT
FILTERED BALANCE STATION, WHICH USES A REMOTE
BLOWER.

Routine Maintenance Schedule

Weekly

 Wipe down the interior surfaces of the enclosure with a disinfectant or

cleaner, depending upon the usage of the unit and allow to dry.

 Using a damp cloth, clean the exterior surfaces of the enclosure,

particularly the front and top to remove any accumulated dust.

 Operate the exhaust system, noting the airflow velocity through the

enclosure using a source of visible smoke. Airflow monitors are
recommended for constant monitoring.

Monthly (or more often as required)

 Determine the actual face velocity through the sash opening of the

enclosure where the average reading should be at the specified velocity.
(Use calibrated thermal anemometer or other approved apparatus). Airflow
alarms are recommended for constant monitoring.

 The enclosure rear baffle should be checked for any blockage to ensure that

the enclosure is maintaining proper airflow.

 All weekly activities.
 Check face velocity. Increase speed control or change HEPA filter when

face velocity of the enclosure drops below the recommended speed for your
facility or if the airflow alarm monitor alerts you. Airflow monitors are
recommended.

 While the enclosure is filled with the contaminant, test filter condition on

Odor Control carbon filters using the appropriate gas detector tube at
intervals of 20% of the total estimated time. The exception to the 20%
recommendation is formaldehyde or any carcinogen or suspected
carcinogen. These hazardous chemicals must be checked at least every
10% of the total estimated time. Gas detector tubes for the specific
chemicals that are being used in the enclosure can be obtained from your
laboratory supply dealer.

 Replace Odor Control carbon filters when chemical breakthrough is

indicated by odor, time, detector tube, or for some chemicals, analytical

instrumentation. See “Replacing Odor Control Carbon Filters” section of

this manual in Chapter 6.

Annually

 Replace the fluorescent lamps.
 Have the enclosure validated by a qualified certification technician. See

Certification and Recertification in Chapter 6.

 All monthly activities.

Decontamination

When used in conjunction with biohazards, the XPert Filtered Balance System and
XPert Filtered Balance Station should be decontaminated with formaldehyde gas before:

 Maintenance work in contaminated areas
 HEPA filter changes
 Moving the cabinet to a new location
 Changing research programs
 After a gross spill of biohazardous material

The procedures for performing a gaseous decontamination are thoroughly outlined
in the U.S. Department of Health, Education and Welfare booklet entitled
Formaldehyde Decontamination of Laminar Flow Biological Safety Cabinets,
available from NIH, Division of Safety, Bethesda, MD 20892, call 301-496-2801,
or from Labconco Corporation.

Determination of When to Replace HEPA Filters

The HEPA filters in the filtered enclosures gradually accumulate airborne
particulate matter and powders from the enclosure and room. The rate of
accumulation will depend upon the cleanliness of the room air, the amount of time
the enclosure is operating, and the nature of work being done in the enclosure. In
typical installations and usage, the HEPA filters will last two to five years before
requiring replacement. Replace HEPA filters when face velocity drops below the
recommended 60-80 fpm velocity, and the speed control is adjusted to full speed.
Replace HEPA filters if it fails the HEPA Filter Leak Test in Chapter 6.

How to Install a New HEPA Filter with the Bag-In/
Bag-Out Procedure for XPert Filtered Balance

Systems and Stations

The XPert enclosures include a true bag-in/bag-out filter disposal system for safely
removing the HEPA filter and protect the worker from toxic powders and
particulates. See Figures 6-1 for the Bag-In/Bag-Out Procedure. For your safety,
wear appropriate personal protective equipment during the change of HEPA filters.
If working with biohazardous materials, use the decontamination procedure outlined
in Chapter 6. (Consult your Safety Officer before performing filter changes).

Do NOT contact blower wheel while still in motion.

NE PAS être en contact avec la roué du ventilateur tant qu’il est

en marche.

2. Remove the bungee cords and retaining strap on the bag and extend it out.

The retaining strap provides an extra level of safety even though the
enclosure is under negative pressure when the blower is on. Do not remove
the black trim seal on leading edge of access port flange.

3. Loosen the two filter clamp bolts with a 9/16" socket securing the HEPA

filter. See Figures 4-1 and 4-2.

4. Place both arms in the rear gloves of the bag, and carefully draw the HEPA

filter out of the enclosure. Rest the HEPA filter on the floor, table or cart.
Remove arms from bag gloves.

5. Create two seals between the enclosure bag access port and the old HEPA filter.

Seals can be heat sealed or sealed with tie wraps. Cut off the bag between the
two seals and leave the bag stub on the access port to the enclosure.

6. Place the new HEPA filter in the new bag. Slide the shock cord of the old

bag forward against the back edge of the black trim seal. Place the new
bag and new HEPA filter over the old bag stub and onto the enclosure
access port. The new bag shock cord should be located past the old bag
shock cord, and against the access port mounting flange. The new bag
should be oriented on the access port with one glove down and two gloves
centered on the upper part of the bag.

7. Carefully remove the black trim seal and old bag stub using the single

glove near the access port. Reattach the retaining strap on the perimeter of
the new bag at the enclosure access port. Draw the black trim seal and old
bag stub into the single glove and turn the glove inside out. Double seal
this glove and cut off the glove with the contaminated bag stub inside.

8. Carefully install the new HEPA filter and uniformly tighten the two filter

clamp bolts until the HEPA filter gasket is compressed 50%.

9. Carefully fold and roll the new bag in four-inch pleats and push the bag

into the access port. Install the new black trim seal with the inside barb

the switched control panel and below the front panel. See Figure 6-1.

3. Adjust the speed control with a small Phillips screwdriver by turning the

screw counterclockwise to increase blower speed or clockwise to decrease
the blower speed. The speed control is very sensitive, so proceed with
caution.

4. Measure the inflow velocity per the averaging technique outlined in

Chapter 3 and adjust the speed control slowly for the desired speed. Allow
the speed to stabilize and re-measure the inflow velocity to confirm.

5. Replace the front panel and tighten the screws.

Calibrate and Operate the Airflow Monitors

Option

Guardian Airflow Monitor (LED Monitor)

Refer to Figure 6-2 for operation and calibration.

Labconco Airflow Monitor/Airflow Switch Operation

The Guardian Airflow Monitor (LED) consists of a circuit board and an airflow
switch. This switch indicates airflow as safe or low. It does not provide an actual
face velocity, but a small setscrew in the back of the sensor can adjust the airflow

level that it classifies as “good/safe” or “low/alert.”

The circuit board provides power to the sensor and also contains a “safe (green)”
and “alert (red)” airflow LED indicators, as well as a “SILENCE ALARM” button

to quiet the audio alarm. When first powered up, the PCB will light both red and



Chapter 6: Maintaining Your Filtered Enclosure

41

green LED indicators and sound the alarm to indicate it is working. After 5
seconds, the air monitor will indicate either good or bad airflow based on what the
connected airflow switch detects. For low airflow, the unit will wait for 10

seconds of bad indications before it sounds both the audio alarm and the red “alert”
LED indicator. If the “SILENCE ALARM” button is pressed, the audio alarm will

be silenced, but the red “alert” LED will remain on. The alarm is silenced
indefinitely unless an airflow change is detected. If safe airflow is later detected

for 10 seconds, the green “safe” LED will be lit and the “alert” (red) LED will be

shut off. At any time the airflow is safe/good, one can press the SILENCE
ALARM test button and the audio alarm and the red LED will turn on as long as
this button is held down. The PCB has also a two-pin connector for use as an
external output with isolated relay contacts that close when the red/alert LED is lit

(low airflow). These relay contacts are not affected by the “SILENCE ALARM”

button.
The PCB is mounted behind the front panel using standoffs and an appropriate

label is used to highlight the “SILENCE ALARM” button with clear areas for the

red and green LED’s. No holes to allow sound to be broadcast louder are

necessary.
The PCB can be prepared as a factory special with an additional connector for the

following external inputs, and having the following possible functions:
 External Alarm allows an external signal to sound the alarm, such as a sash

open switch, or a “fail” signal from the building airflow system.

 Alarm Disable allows an external signal to prevent a “low” airflow alarm from

occurring.

 Night Setback allows an external signal to prevent a “low” airflow alarm from

occurring (not any different from Alarm Disable above other than the
terminology.)

Contact Labconco for ordering information on this special PCB.

Calibration

1. Ensure the flow switch and alarm circuit board are installed and

operational.

2. Allow the enclosure to operate for at least two minutes.

3. If factory installed, the monitor will alarm at 60±10 fpm with the inflow

velocity set at 90±10 fpm.

4. To change the factory setting, set the inflow velocity required by your

Safety Officer to the desired alarm condition using the speed control
adjustment procedure outlined in Chapter 6.

5. Once the alarm condition is set, use a small screwdriver to turn the

adjustment screw on the airflow switch counterclockwise (facing the

screw) until the “low” airflow red LED lights and the audible flow alarm

sounds.

Chapter 6: Maintaining Your Filtered Enclosure

6. Adjust the inflow velocity to the nominal operating point required by your

Safety Officer.

7. Over time the HEPA filter will load and eventually slow the inflow

velocity. Once the alarm condition is met, simply increase the speed
control outlined in Chapter 6 or replace the HEPA filter if the speed control
is maximized.

8. The table below lists typical alarm conditions based on normal operating

conditions. Typical alarm conditions are set at face velocities of 10 to 30
feet per minute below the normal operating conditions due to supply air
and exhaust air fluctuations, as well as room air cross drafts. Consult your
Safety Officer for proper operating speeds.

Guardian Digital 1000 Airflow Monitor

Option

Refer to Figure 6-3 for operation and calibration. Refer to the separate Labconco
1000 Alarm Manual for detailed information.

Operation

The Guardian Digital Airflow Monitor consists of the airflow sensor, the Alarm
Unit, and the 15 VDC power supply. For 115V operation the alarm unit is
powered by plugging the power supply into the factory-prepared digital airflow
monitor socket. For 230V operation, the Alarm Unit is powered by plugging the
power supply into a building outlet. The alarm has “Enter,” “+,” and “-” buttons to

program the monitor. There is also a green LED “SAFE,” yellow LED
“CAUTION,” and red LED “LOW” with audible alarm for airflow conditions.

The audible alarm can be permanently muted if desired. The Guardian Digital
1000 Airflow Monitor displays a face velocity value, provides an RS232
communications port to a PC or building computer system, can be configured for
external input connections such as night setback or external alarm and provides up
to three output relays that can be configured. For complete detailed information,

please refer to the separate Labconco 1000 Alarm User’s Manual provided with

the enclosure.

Calibration

The filtered enclosure comes factory calibrated with the monitor alarm at 60 ± 10
fpm with the inflow velocity set at 90± 10 fpm.

Programming the Guardian 1000 Digital Alarm

Set the desired face velocity of the enclosure with the sash in the down position
using an average face velocity of readings from a thermal anemometer.

a. 2 ft enclosure – 2 readings
b. 3 ft enclosure – 3 readings
c. 4 ft enclosure – 4 readings

Configure Alarm

To successfully calibrate the airflow monitor, it will be necessary to change the
face velocity by adjusting the airflow exhaust volume. The exhaust volume can be
adjusted using the speed control located behind the front panel on the XPert
Filtered System. For the XPert Filtered Station, the exhaust volume is adjusted
through a damper in the building exhaust system.

The following inflow face velocity speeds are recommended to successfully
calibrate. To begin, determine what the low airflow, low warning airflow, normal
airflow, and high airflow shall be.

Determination of When and How to Replace Odor

Control Carbon Filters

The carbon filters MUST be replaced when any one of the following two
conditions are met:

1. The filtered enclosure outlet (exhaust) concentration approaches the inlet

concentration, indicating filter saturation.

2. The odor in the work area becomes intolerable or the concentration of the

chemical in the work area is greater than the TWA.

There are four means of determining when its time to change the carbon filters (not
shown in the order of preference).

Odor - A person’s sensitivity to odor, tolerance of odor and their comfort level

under odoriferous conditions vary with the individual. While odor is an indicator
that chemicals are passing through the carbon filter, several points need to be
understood:

 Odor within the room is not necessarily an indication of saturation or

hazardous exposure concentrations.

 Odor can be used as a prompt to sample the chemical concentration on the exit

side of the carbon filter.

 Organic chemicals approved for use in the filtered enclosure have odors that

are detectable before reaching the time weighted exposure limits.

Detection Tubes - Color change indicators can be used to measure the
concentration of the chemical at the exit side of the carbon filter or in the outlet
exhaust. A kit including syringe pump and flexible tubing can be purchased as an
accessory from Labconco (Catalog # 6924900). Labconco Customer Service
Representatives are supplied with detector tube catalog numbers, as well as
telephone numbers to direct you to where to purchase these items.

For Organic, Formaldehyde and Ammonia, chemical specific detector tubes should
be purchased when installing fresh filters. Each kit contains instructions on how
many strokes of the syringe are required to obtain the stated sensitivity. The
sampling syringe is connected to the filtered enclosure exhaust. Connect the
syringe to the detector tube while the system is running and pull the air through the
tube with the syringe. Each stroke of the syringe represents a 100-ml sample and
corresponds to the number of strokes necessary to give the indicated color changes.

Due to the wide variety of organics and varying TWA’s, it is recommended that

specific detector tubes be purchased directly from Sensidyne, Draeger or your
laboratory supply dealer. Alternate detector pumps can also be purchased from
your laboratory supply dealers.

The vast majority of detector tubes available start measuring at the TWA. When a
user observes a color change in the tube, they should replace the filter
immediately. If no detector tube for your specific chemical is available, other
means of detection must be used.

Chapter 6: Maintaining Your Filtered Enclosure

Product Service 1-800-522-7658

48

Time - For applications that have very consistent inlet concentrations and

operating time, “Time” can be used to anticipate saturation or TWA levels based
on prior experience. However, this does not replace the need for sampling.
Consult Labconco technical specialist for an estimate of carbon filter life based on
chemical usage. Detector tubes, or analytical instrumentation should always be
used to determine concentrations in the carbon filter. It is recommended that the
carbon filters be checked with detector tubes or other means at intervals of 20% of
the total estimated filter life. The exception to the 20% recommendation is
formaldehyde and any carcinogen or suspected carcinogen. These more hazardous
chemicals must be checked at least every 10% of the total estimated time.

Analytical Instrumentation - This is the most accurate means of measuring
concentrations of any chemical. It is the method of choice when no detector tubes
are available or the tubes are not sensitive enough to measure at the TWA
concentration for the chemical. This method is also to be used to determine
saturation when the chemical concentration is below the measurement range of
detector tubes.

Odor Control Carbon Filter Replacement Procedure – See Figures 4-1 and 4-2
for Carbon Filter Replacement.

1. The carbon filters are replaced by first removing the two screws, which

hold the clips to secure the upper diffuser screen. Remove the screws, clips
and upper diffuser screen.

2. Remove the carbon filter in a careful way to avoid the flow switch and

HEPA filter.

3. Re-install the new carbon filter with the gasket down. Replace the upper

diffuser screen, clips and two screws.

4. The weight of the carbon filter with the gasket down will compress the

gasket.

Calculating Odor Control Carbon Filter Life

Labconco developed a modeling program to estimate the filter life for typical
carbon filters. Since filter life is dependent on the chemical used, the airflow, filter
size, and the dwell time, refer to the Chemical Guide for the Paramount® Filtered
Enclosure. The estimated life for Odor Control carbon filters for the filtered
enclosures is conservatively calculated at 50% or half of the published values for
the Paramount in the Chemical Guide. For example, if you use isopropyl alcohol
to disinfect and use approximately 100 ml per week during 2 hours of use per day
then follow these steps to calculate the concentration in parts per million (ppm).

Chapter 6: Maintaining Your Filtered Enclosure

Product Service 1-800-522-7658

49

Steps for Calculating PPM and Filter Life

1. Determine the amount of the proposed chemical lost to evaporation over a

given amount of time. For example, if you use isopropyl alcohol and lose
approximately 100 ml per week during 2 hours of use per day.

2. Convert the amount lost into ml/min. For this example:

100 ml X 1 week X 10 hours = 100 ml lost
week 10 hours use 600 minutes 600 minutes

3. Convert ml/min to PPM by multiplying ml/min by the conversion factor

found in the second to the last column on the right. For isopropyl alcohol
.17 x 41 = 7.0 PPM.

4. Find the PPM value on the chart that comes closest to the value you just

calculated in step #3. In this example, round up to 10 PPM, which is close to
the calculated 7.0. We may approximate the filter life to be around 155 hours
of actual use, but use 50% of this for the Odor Control filters or 78 hours.

5. Insert the estimated filter life into the estimated usage to determine how

long filters will last.

Initial Certification

The filtered enclosure has been certified at the factory for an inflow velocity of
90±10 fpm along with the HEPA Filter Leak Test. The filtered enclosure should
be certified for the proper inflow velocity required by your Safety Officer. It is
also a conservative recommendation to perform the HEPA Filter Leak Test again
should there be any damage caused during transport.

Re-Certification

Under normal operating conditions, the enclosure should be recertified at least
annually if serviced. The certifier should perform the following tests.

 Inflow Velocity Test
 HEPA Filter Leak Test

In addition, the following tests should also be performed at the user’s discretion:

 Measure of Line Voltage and Current
 Smoke Test to determine proper airflow patterns
 Lighting Intensity Test (when appropriate)
 Noise Level Test (when appropriate)
 Vibration Test (when appropriate)

Chapter 8:
Troubleshooting

Refer to the following table if your filtered enclosure fails to operate properly. If
the suggested corrective actions do not solve your problem, contact Labconco for
additional assistance.

PROBLEM

CAUSE

CORRECTIVE ACTION

Contaminants outside of
enclosure.

Improper user
techniques for the
enclosure.

See “Certifying the Enclosure” Chapter 3 and
“Safety Precautions” Chapter 4 sections in the

manual. (Ref. Appendix D).

Restriction of the baffle
air slots or blockage of
the exhaust outlet.

Remove obstruction to ensure that all air slots
and the exhaust outlet are unobstructed.

External factors are
disrupting the enclosure
airflow patterns or
acting as a source of
contamination.

See “Location Requirements” Chapter 2,
“Certifying the Enclosure” Chapter 3, and
“Safety Precautions” Chapter 4 sections of

this manual. (Ref. Appendix D).

Enclosure has improper
face velocity.

Have enclosure certified and check exhaust
system. Check HEPA filters for loading.
Adjust enclosure speed control. Enclosure
should have an average face velocity of 60­100 fpm for weighing procedures and 75-105
fpm for biohazardous procedures.

Blower won’t operate.

Unit not plugged into
outlet.

Plug the enclosure into appropriate electrical
service.

Circuit breaker(s) or
Ground Fault
Interrupter.

Reset circuit breaker.
Blower wiring is
disconnected.

Inspect blower wiring.

Blower switch is
defective.

Replace switch.

Motorized impeller or
blower is defective.

Replace motorized impeller or blower. See
Chapter 6.

Low face velocity or poor
containment of contaminants.

Enclosure sash not
closed.

Close sash to the lowest position.
HEPA filter clogged.

Replace HEPA filter or increase speed.

Carbon filter loaded
with chemicals.

Replace carbon filter.

Blower and lights won’t

operate.

Unit not plugged into
outlet.

Plug enclosure into appropriate electrical
service.

Circuit breaker(s)
tripped.

Reset or replace circuit breaker.

Chapter 8: Troubleshooting

Product Service 1-800-522-7658

63

PROBLEM

CAUSE

CORRECTIVE ACTION

Lights do not work.

Lamp not installed
properly.

Inspect lamp installation.

Lamp wiring
disconnected.

Inspect lamp wiring.
Defective lamp.

Replace lamp.

Light switch is
defective.

Replace light switch.

Defective electronic
ballast.

Replace ballast.

Airflow monitor malfunction.

No power.
No lights.
No display.

Power cable to circuit board is disconnected
and needs to be connected. Sensor cable
needs to be connected. Power supply is not
plugged into proper voltage; plug in power
supply. Verify that all airflow monitor
interface cables are connected. Check fuses
on enclosure.

No audible alarm.

Alarm has been temporarily silenced using
“SILENCE ALARM” or “enter” buttons.

Wrong alarm set point.

Airflow monitor was not properly adjusted.
Repeat calibration steps outlined in this
manual in Chapter 6 or in the supplied
Digital 1000 Monitor Manual.

Constant audible alarm.

Check airflow and calibration of airflow
monitor. See Chapter 6.

Continuous alarm.

Check the face velocity of the enclosure as
the airflow of the system may have changed.
If incorrect, adjust the speed control to
increase face velocity. The HEPA filter may
have become loaded. If face velocity is
correct, calibrate the airflow monitor
outlined in this manual in Chapter 6.

Monitor alarms; air way
to airflow monitor
sensor is blocked by
insects, dust or debris.

Lightly clean the airway with clean air. Be
careful not to touch sensitive electrical
components.

Audible disable will not
stay operational.

An alarm condition must be continuously
present before the audible alarm can be
silenced. If flow conditions fluctuate near
the alarm set point, the airflow monitor will
automatically reset it. Action should be
taken to bring the enclosure airflow into
proper operating parameters or adjust the
alarm set point lower.

*Excludes XPert Filtered Balance Station, since it has no integral blower.

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. 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.

Appendix E:
Balance Stability

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.

Appendix F:
DOP Test Kit for Dual HEPA
Filters

Operation

The DOP Test Kit (5242401) for Dual HEPA filters includes the connections,
hoses, and test procedure necessary to conduct a HEPA filter leak test on the
secondary redundant HEPA filters. The HEPA filter leak test is performed to
determine the integrity of the HEPA filter(s), the filter housing, and the filter seals.
The leak test is to be done by a qualified technician with calibrated equipment.
Reference Leak Testing and Photometer scanning from the Institute of
Environmental Services (IES-RP-CC001.3). Important: Refer to the following
pictorials to successfully set up the Dual DOP Test Kit and test equipment and run
the test procedure.

Equipment Required

1. An aerosol photometer ATI model 2D, 2E, 2G or equivalent. Air

Techniques Hamilton Associates Inc. 11403 Cron Ridge Dr. Owings Mills,
MD 21117

2. One aerosol generator of the Laskin nozzle(s) type. An aerosol of mineral

oil or suitable liquid shall be created by flowing air through it. The compressed
air supplied to the generator should be adjusted to a pressure of 10± 1 psig.
during operation. Air Techniques Inc. Model TDA-4A or equal. One nozzle at
10 psig is (67.5 cfm x 100ug/l)/(Vol. of air), For the 2' at 90 fpm or 130 cfm,
one nozzle @10 psig is 6,750/130 cfm = 52 ug/l. However, to enable proper
DOP coverage for the upper 2' Dual HEPA filter, test each third section
separate and set photometer at 3 times or 156 ug/l. For the 3' at 90 fpm or 200
cfm, one nozzle @ 10 psig is 34 ug/l. For the 4' at 90 fpm or 265 cfm, one
nozzle at 10 psig is 26 ug/l. For the 5' at 90 fpm or 215 cfm, one nozzle at 10
psig is 31 ug/l. For the 6' at 90 fpm or 260 cfm, one nozzle at 10 psig is 26
ug/l. Note 5' and 6' use two filters.

3. Mineral oil (Catalog #1491400).

4. Sampling Nozzle, Rectangular 1/2" x 3-1/4", Air Techniques, Inc.

Procedure

For the ATI 2G Photometer

1. Turn on the photometer and allow it to operate for a minimum of 5 minutes.

Leave the valve in the “CLEAR” setting.

2. Press the “ENTER” keypad. Press the “REF” keypad.

3. The display will display “P1” for approximately 1 second, and then display a

numerical value.

4. Using the “^” or “ν” keypads, respectively, increase or decrease the numerical

value until it equals 52 (2'), 34 (3'), 26 (4'), 62 (5'), 52 (6') for the enclosure at
90 fpm inflow velocity.

5. Press the “ENTER” Keypad. The photometer will scan for 15 seconds, and

then the “0” keypad will flash. Press the “Enter” keypad. The unit will scan for
5 seconds, the display will read “0000,” and the unit will sound a confirming

tone.

6. Set the valve to “DOWNSTREAM.” Place the palm of your hand over the

sampling port of the pistol. There should be a strong vacuum at this port. If the
vacuum is weak, contact Air Techniques Hamilton Associates.

7. Turn the enclosure on and let it operate for a minimum of 5 minutes.

8. If necessary, adjust the speed control of the enclosure to maintain the following

airflows at 90 fpm; 2' (130cfm), 3' (200 cfm, 4' (265 cfm.), 5' (108 cfm), 6'
(130 cfm). The 5' and 6' uses two filters.

9. Position the aerosol generator discharge to the three ports below the secondary

HEPA Filter. See pictures that follow.

10. Start the aerosol generator (Pressure to be +/- 1 psig). (10 psig). Ensure that

one Laskin nozzle is in the “open” position.

11. Allow the generator to operate for a minimum of 15 seconds. For all integral

motorized impeller models, scan the downstream exhaust side of the HEPA
filter by passing the sampling nozzle of the gun in slightly overlapping strokes
over the entire surface the filter, with the sampling port not more than 1 inch
from the surface of the filter media. Scan the entire periphery of the filter and
the gasket between the filter frame and the enclosure frame. Scanning shall be
done at a traverse rate of not more than 2 inches per second.

Acceptance

Aerosol penetration shall not exceed 0.01 percent measured by the photometer.
