Introduction

Congratulations on your purchase of a Labconco XPert® Filtered Balance System or XPert® Filtered Balance Station. 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. 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. See chart below 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.

Product Service 1-800-522-7658

Chapter 2: Prerequisites

 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.

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.

Surface Resistivity Table

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

 Next to doorways or windows that may be opened.

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.

Product Service 1-800-522-7658

Chapter 2: Prerequisites

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.

We recommend that you do not remove the enclosure from its shipping container until it is ready to be placed into its final location. Move the unit by placing a flat, low dolly under the shipping skid, or by using a floor jack.

Do not move the enclosure by tilting it onto a hand truck.

Installing the Filtered Enclosure on a Supporting Structure and Work Surface

Use caution when lifting or moving the enclosure. When installing the enclosure onto a chemical-resistant work surface or benchtop, ensure that the structure can safely support the combined weight of the enclosure and any related equipment. The work surface should be at least as wide as the enclosure to properly support it. The front of the enclosure should be aligned within 0.3" of the front of the work surface. Mounting holes are provided in the Labconco accessory work surfaces to secure the enclosure. RTV Silicone sealant must be applied for additional support.

Work Surface Specifications

The work surface should be smooth, rigid, and durable. The surface should be non-porous and resistant to the powders, solvents and chemicals used in conjunction with the XPert Filtered Enclosure.

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.

Important: Carbon filters do not provide any particulate protection, but provide odor control.

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

Product Service 1-800-522-7658

Chapter 3: Getting Started

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.

Figure 4-4

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.

Product Service 1-800-522-7658

Chapter 4: Performance Features and Safety Precautions

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.

Product Service 1-800-522-7658

Chapter 4: Performance Features and Safety Precautions

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

Product Service 1-800-522-7658

Chapter 4: Performance Features and Safety Precautions

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.

Product Service 1-800-522-7658

Chapter 4: Performance Features and Safety Precautions

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.

Product Service 1-800-522-7658

Chapter 4: Performance Features and Safety Precautions

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 Labconco at 1-800-821-5525 or 1-816-333-8811.

 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.

Product Service 1-800-522-7658

Chapter 5: Using Your Filtered Enclosure

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.

Product Service 1-800-522-7658

Chapter 5: Using Your Filtered Enclosure

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.

Product Service 1-800-522-7658

Chapter 5: Using Your Filtered Enclosure

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:

Product Service 1-800-522-7658

Chapter 5: Using Your Filtered Enclosure



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 motorized impeller cannot be exposed to acids. Where applications require the use of 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.

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.

Chapter 6: Maintaining Your Filtered Enclosure

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).

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 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:

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.

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.

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.

Chapter 6: Maintaining Your Filtered Enclosure

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.

Product Service 1-800-522-7658

Chapter 6: Maintaining Your Filtered Enclosure

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).

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. 78 hours filter life

10 hours per week use

Formaldehyde only

For formaldehyde, use 10% of the impregnated carbon weight. Formalin is 37% formaldehyde by weight. The density of formalin is 1.08 g/ml.

Ammonia only

For ammonia, use 10% of the impregnated carbon weight. Assume use of a 50% solution of ammonia for these calculations.

Chapter 6: Maintaining Your Filtered Enclosure

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)

Fluorescent Light Replacement

1. Disconnect the power.

2. Locate the small light reflector located under the control panel shown in

Figure 6-2 and Figure 6-3.

3. Remove the light reflector support by removing two Phillips screws on the

bottom of the light reflector.

4. Rotate and remove the old fluorescent lamp.

5. Reinstall the new fluorescent lamp and light reflector in reverse order.

6. Power the unit up and try the new fluorescent lamp.

Appendix C: Specifications

This Appendix contains technical information about all the XPert Filtered Enclosures including electrical specifications and environmental operating conditions.

Electrical Specificiations

 2', 3' and 4' – 3 Amps, 115V or 2 Amps, 230V, 50/60 Hz  5' and 6' – 5 Amps, 115V or 3 Amps, 230V, 50/60 Hz

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.

Appendix D: Quick Chart

*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.

Product Service 1-800-522-7658

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.
