Introduction
Congratulations on your purchase of a Labconco TXE. Your enclosure provides
personnel protection through superior containment. 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. The TXE offers 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 TXE features so that you can use the filtered enclosure
efficiently.
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 TXE, 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 TXE, 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 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 TXE electrical and
environmental conditions, specifications and requirements.
Location and Air Current Requirements
The TXE has been designed to contain hazards by negating typical cross drafts and
turbulence within the opening. As a precautionary safety measure and a higher
level of quality management, it is recommended that the enclosure be placed in an
area to avoid:
High traffic areas where walking might cause an air disturbance or be a
nuisance to balance readings.
Overhead or wall HVAC diffusers, fans, radiators or other lab equipment
producing air currents.
Next to doorways or windows that may be opened.
Do not position the unit so that it is difficult to operate the main
disconnect device.
Ne placez pas l'appareil de sorte qu'il est difficile de faire
fonctionner le dispositif principal de déconnexion.

Exhaust and Blower Requirements
The TXE 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.
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.
Data for the exhaust volume, noise pressure and enclosure static pressure loss are
listed for the TXE at face velocities of 80 and 100 fpm.
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 TXE or
other equipment. The enclosure includes pass-thrus to allow electrical cords through
the back of the enclosure without leaving a large hole for contaminants to escape.
TXE Connected to Building Exhaust
There is no provision for controlling a remote blower for exhausting air from the TXE.
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 TXE is then plugged into this receptacle.
Space Requirements
The dimensions for the different models are shown in Appendix B: Dimensions.

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 TXE has been designed to accept 6" diameter
ductwork as shown in Figure 3-2. The exhaust connection ships uninstalled and
needs to be fastened with the screws provided. See Chapter 7 for ordering Canopy
Exhaust Connection for the TXE. Canopy Exhaust Connection aids in the removal
of chemicals or odors not captured by HEPA filters. Review Chapter 2 for exhaust
prerequisites and review Chapter 7 for ordering blower exhaust equipment.
Consult Labconco Customer Service should you require help sizing your blower
for the exhaust volume and system static pressure loss.
To ensure compatibility, the selected exhaust duct material
should match the enclosure, procedures and chemical
applications.

Installation of 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 TXE has a true bag-in/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.
Connecting the Electrical Supply Source to the TXE
115V Models
Simply connect the 115V power cord supplied to the IEC electrical supply plug on
the back of the enclosure.
For the remote blower used for the TXE, 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 TXE should be
performed by a licensed electrician and conform to local codes. In most cases, the
TXE will require the use of shielded conduit to protect the wiring.
See Figure 3-3. The grounding connection shall not be made to the terminal box
cover. The building electrical supply system for the remote blower should include
overload protection such as a switch or circuit breaker in close proximity and
within easy reach of the operator. The switch or circuit breaker shall be marked as
the disconnecting device. Consult NEC-2002 for proper installation.
