Introduction

Congratulations on your purchase of a Labconco XPert® Nano Enclosure. 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 Nano Enclosure uses an ULPA filter, which
is rated at least 99.999% efficient for 0.12-micron particles. The XPert Nano
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. The XPert Nano Enclosures include a true
bag-in/bag-out ULPA filter to properly protect personnel during filter changing
operations.

If the unit is not operated as specified in this manual it may
impair the protection provided by the unit.

Chapter 2:

Prerequisites

Before you install the filtered enclosure, you must be certain that the area is level
and of solid construction. In addition, a dedicated source of electrical power
should be located near the installation site to power the filtered enclosure.
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 or stand.
For weighing applications 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.

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

may be appropriate.

Product Service 1-800-522-7658

Chapter 2: Prerequisites

4

 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 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 Nano Enclosure avoids
the use of plastics, which are highly insulative.

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.

 The XPert Nano Enclosure is offered with a factory installed ionizer which

will neutralize surface charges.

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. 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 line of 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 control, 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.

Exhaust and Blower Requirements

The XPert Nano Enclosure uses an integral motorized impeller to draw room air
past the operator and through the enclosure. This contaminated air is then pushed
through the ULPA filter. The ULPA-filtered exhaust air is then forced out the top
of the enclosure.

The ULPA-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. Consult your local regulations or guidelines for ventilation of the
filtered exhaust in nanoparticle applications.

If external exhaust is required, data for the exhaust volume, noise pressure and
enclosure static pressure loss is listed for each filtered enclosure model at face
velocities of 60, 80, and 100 fpm. Weighing and handling nano materials is best done
with lower flow rates (60-70 fpm or 0.31-0.36 m/s).

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.

Space Requirements

Connecting to the Exhaust System (Optional)

ATTENTION: The weight of the exhaust ductwork system
must be supported independently of the enclosure
superstructure or damage may occur.

The exhaust system should be installed by a qualified HVAC
contractor.

The exhaust connection on the 2', 3' and 4' XPert Nano Enclosure have been
designed to accept 6" diameter ductwork as shown in Figure 3-2. The 5' and 6'
models have been designed for 10" diameter ductwork as shown in Figure 3-3.
For the 2', 3' and 4' sizes, the exhaust connection ships uninstalled on the top and
needs to be fastened with the screws provided. See Chapter 7 for ordering Canopy
Exhaust Connection. Canopy Exhaust Connection aids in the removal of
chemicals or applications where a higher degree of powder and particulate removal
is required. Review Chapter 2 for exhaust prerequisites and review Chapter 7 for

Connecting the Electrical Supply Source to the
Nano Enclosure

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%.

The same procedure applies for the 230V except it is shipped without a plug.
Install the appropriate plug for your electrical specifications per local codes. All
models use less than 5 amps.

All wiring for the XPert Nano Enclosure should be performed by a licensed
electrician and conform to local codes.

Do not use any detachable power cord that is not adequately rated

for the unit.

Ne pas utliser un fil électrique amovible qui n’est pas du tension

nominale de l’appareil.

Set the Face Velocity with the Speed Control Adjustment

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. (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
permissible for the application will give the least turbulent, quietest operation. Face
velocity measurements are made using an anemometer. An electric anemometer can be
obtained from your laboratory supply dealer.

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
performed containment testing to validate the enclosures for sodium naproxen
powders. The XPert 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 Nano Enclosures provide a safe working
environment.

High Performance Features and

Safety Precautions

High Performance Features

The patented1 XPert Nano Enclosure is 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 Labconco line of
enclosures so unique is the revolutionary way they direct air into and through the
contaminated air chamber. Labconco engineered them 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 ULPA 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 Nano Enclosure includes a true bag-in/bag-out ULPA filter disposal
system to protect the worker from contact with hazardous powders and
particulates. Users 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. The air foil is easily removable for cleaning. Do
not operate the enclosure without the air foil installed.

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.

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.

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. The rear perforated baffle may be tilted or removed
for ease in cleaning.

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

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

6. 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. The 5' and 6' units utilize a gas spring
assist in place of the latch.

7. Utility Ports allow electrical cords and data cords to pass through the back

of enclosure without leaving a large hole for contaminants to escape.

8. 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.

9. Inherently Safe Plenum 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.

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

which eliminates transfer of vibration to the work surface. The impeller
wheel is also dynamically balanced.

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

by the certifier to adjust the inflow velocity. Located behind the front
panel.

12. 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.

or 10" (5' and 6') diameter transition to a remote blower or house exhaust
system.

20. Optional Accessory Canopy Exhaust Connection (not shown) is

available to duct the XPert Nano Enclosure to the outside. The Canopy
Exhaust Connection affords the operator additional protection from
hazardous particulates, fumes or vapors. 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.

21. Optional Ionizer (not shown), when activated, floods the work area with

positive and negative ions to neutralize static charges on the surface of non­conductive items. Ionizer cannot be installed after manufacture.

22. Upper Diffuser Screen provides protection for the ULPA Filter and (LED)

airflow sensor. See Figure 4-1.

23. Optional Utility Shelves (not shown) allow the user to hold utensils and

printers on shelves inside the enclosure. See Chapter 7.

Safety Precautions

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

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

Product Service 1-800-522-7658

Chapter 4: Performance Features and Safety Precautions

21

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.)

5. Always work far back into the enclosure as possible. Keep all powders,

chemicals and apparatus inside the lower air foil.

6. Perchloric acid use in this enclosure is prohibited.

7. Radioisotope materials are prohibited in this enclosure. Consult your

Safety Officer.

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

annually thereafter.

9. Use safety goggles, protective clothing, gloves and any other personal

protective equipment recommended by your safety officer.

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

11. The ULPA 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.

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

13. ULPA filters are only effective for entrapment of particulate matter.

Manipulations that generate gases or vapors from toxic chemicals or
radionuclides, must be evaluated carefully and vented in compliance with
applicable regulations.

14. The surface of the ULPA filter is fragile and should not be touched. Care

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

15. The ULPA 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 operating time and the nature of work being done.

16. 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.

Product Service 1-800-522-7658

Chapter 4: Performance Features and Safety Precautions

22

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

impeller on the XPert Nano Enclosure. Change the filter when the face
velocity falls below acceptable limits established by your Safety Officer.

18. Exhaust ULPA filters are disposed as hazardous waste. The user is

responsible for recording the material and disposing properly. Filters
should be disposed using the disposal bag on XPert enclosures.

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

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

20. 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 (see
references in Appendix D).

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

effective operation.

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

been completed.

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

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

24. Tag enclosures with appropriate warning, if the enclosure has been disabled

for service.

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

be vacated and ventilated.

Chapter 5:

Using the Nano Enclosure

Now that the installation of your Nano enclosure is completed, you are ready to
use your Nano enclosure.

Read this chapter to learn about:

 Routine Daily Work Procedures
 Appropriate ULPA Filter Applications, Suitability and Guidelines
 Optional Ionizer
 Prohibited Acid Use

Routine Daily Work Procedures

Planning

 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 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.

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.

Product Service 1-800-522-7658

Chapter 5: Using the Nano Enclosure

24

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.

ULPA Filter Applications, Suitability and Guidelines

 Weighing and handling of powders.
 Release of nonvolatile particulates appropriate for use with a ULPA filter.
 The ULPA 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.

 ULPA 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 ventilation to the outside of
the building. The surface of the filter is fragile and should not be touched. Care
must be taken to avoid puncturing the ULPA filter during installation. If you
suspect that a ULPA filter has been damaged, DO NOT use the enclosure. See
Chapter 6 for replacing the ULPA Filter or using a Bag-In/Bag-Out Disposal Bag.

 The ULPA 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 operating time, and the
nature of work being performed.

 Each Nano Enclosure is provided with a ULPA filter. For powders and

particulates follow the ULPA 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.

Optional Ionizer

The XPert Nano’s optional built-in ionizer is designed to control static charge on
surfaces within the enclosure. The discharge of the ionizer is uniquely located at
the front face of the work surface, safe from the contaminants and cleaning within.

The emitters within the ionizer have a finite life and therefore there may be times
when one might choose to use the enclosure with the ionizer OFF. The
Blower/Ionizer control switch allows the blower to be operated independently of
the ionizer. Push the top of the switch to activate the blower only; push the bottom
to energize the ionizer along with the blower. The green light adjacent to the
ionizer emitters (on the face of the work surface) will illuminate when the ionizer
is active.

Refer to the Maintenance section of this User’s Manual to keep the ionizer

working at its full potential. Cleaning of the emitter points is recommended every
two to three months (based on 8-hr daily operation).

ATTENTION: NEVER operate the enclosure in an explosive
environment. The ionizer may cause detonation. NEVER
operate the ionizer without the emitter points installed; damage
will occur.

Product Service 1-800-522-7658

Chapter 5: Using the Nano Enclosure

26

Prohibited Acid Use

The XPert Nano Enclosure motorized impeller and stainless steel interior should
not 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.

facility or if the airflow alarm monitor alerts you. Airflow monitors are
recommended.

 If equipped with optional Ionizer, clean and inspect emitter points.

Annually

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

Certification and Recertification in this chapter.

 All monthly activities.

Decontamination

When used in conjunction with biohazards, the XPert Nano Enclosure should be
decontaminated with formaldehyde gas before:

 Maintenance work in contaminated areas
 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,

Setting the Inflow Face Velocity with the Speed
Control Adjustment

1. Remove the front panel by loosening the (2) Phillips screws on top that

secure the front panel.

2. The speed control is located on the electrical subassembly located behind

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

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

Product Service 1-800-522-7658

Chapter 6: Maintaining the Nano Enclosure

33

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 circuit board 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 circuit board 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 circuit board 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.

Contact Labconco for ordering information on this special circuit board.

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 ULPA 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 ULPA filter if the speed control
is maximized.

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.

Digital 1000 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 Nano
Enclosure. For XPert Nano Enclosures that are ducted to a roof blower, 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.

Initial Certification

The filtered enclosure has been certified at the factory for an inflow velocity of
90±10 fpm along with the 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 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
 ULPA 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.

Maintenance on the Optional Ionizer

Occasional cleaning of the ionizer’s emitter points is the only routine maintenance

required. Regularly scheduled cleaning extends the life of the unit and sustains the
delivery of ionized air. Clean the emitter points every 60 to 90 days (based on 8-hr
daily operation).

Emitter Point Cleaning

NOTE: Disconnect power to the XPert Nano Enclosure at least
one minute before performing cleaning or replacement of the
Ionizer Emitter Points. The ionizer has a high voltage power
supply that must discharge over that one minute time period.

Emitter points are better cleaned without removal. Use a clean room compatible
(non-shedding) swab moistened with the following solution to gently wipe the
points.

Cleaning solution of 50% IPA (laboratory or electronic grade
isopropyl alcohol and 50% de-ionized water).

Emitter Point Replacement

If the ionizer fails to neutralize charges in the airstream, the only portions of the
ionizer that can be serviced are the emitter points. Do not attempt to disassemble
the ionizer bar located under the work surface. A surface static charge meter is
required to test the ionizer’s effectiveness. Apply a static charge to a piece of
plastic with a synthetic fabric and measure the voltage at the surface before and
after placing it in the airstream with the ionizer ON.

Ionizer Emitter Points Part Number 3884300

Emitter points may require replacement in two to three years or when erosion or
damage is evident. To replace the points:

1. Remove power to the unit for at least one minute

2. Grasp each emitter point with a small needle nose pliers and pull them

out of their socket

3. Install the replacement point with care. Using the needle nose pliers

and gripping the emitter away from the sharp point.

4. Follow the Emitter Point Cleaning instructions above before use.

Appendix C:
Specifications

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

Electrical Specifications

 3 Amps, 100V/115V, 50/60 Hz
 2 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

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.
