Chapter 2:
Prerequisites
Before you install the enclosure, you need to prepare your site for installation.
Carefully examine the location where you intend to install it. You must be certain
that the area is level and of solid construction. A dedicated source of electrical
power should be located near the installation site to power the enclosure.
Additionally, the balance used inside the enclosure should be strategically placed
in the lab to avoid environmental influences.
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 XPert Bulk Powder Enclosures, Filtered
Systems and Filtered Stations.
Refer to Appendix C: Specifications for environmental conditions.

Support, Vibration and Movement Requirements
The XPert Bulk Powder Enclosures all come standard with a support stand, electric
lift and stainless steel work surface.
The ability for analytical balances to accommodate vibration varies with type and
brand. More advanced balances have improved vibration compensation; however
in the preparation of a balance enclosure site, please consider the following:
The corners of a building typically have less vibration than the center.
The work surface with the Bulk Powder Enclosure should not contain any
vibration-producing equipment, such as shakers or pumps.
Although the enclosure’s work surface is a very stable platform, adding a
marble slab with dampening pads is also an effective low cost means of
controlling vibration.
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.
Avoid incandescent lighting of the enclosure where radiant heat produced will
raise temperatures. (See Chapter 7 for adding an accessory fluorescent light
kit to models without a light).
Do not place the enclosure in a location 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 are all enhanced when static
attraction of powders is minimized. The construction of the XPert Bulk Powder
Enclosure avoids the use of plastics, which are highly insulative. The advantages
to the glass and epoxy-coated metal construction are twofold.
1. The enclosure does not contribute high electrostatic forces affecting the
precision of the balance.
2. The attraction and ultimate accumulation of powder (hazardous or
nuisance) are minimized on the inside of the enclosure.

To correct or ensure against electrostatic issues, the following additional measures
may be prescribed to improve weighing operations.
Maintain a humidity level between 45 and 60%. The ability to sustain this
humidity range can be challenging depending upon the regional climate and
HVAC system.
Ionizers in various forms (guns, bars and blowers) are effective ways to flood
an area with ions and essentially “neutralize” electrostatic electricity.
Background on Electrostatics or Static Electricity
Electrostatic charges on a surface such as the wall of a balance enclosure are not
created by moving air. Gases do not cause the charge. Impurities within the air
impinging upon surfaces dictate the polarity and magnitude of the charge. The
process, triboelectrification, occurs when the friction of the dust particles contact
the surface and electrons move across the interface.
The ability of a material to become polarized is a property known as permittivity.
On highly insulative materials like acrylic, ions or charged molecules are strongly
bound to the surface by polarization forces. The higher the force, the higher is the
permittivity value of the material. It is suggested that the use of high permittivity
materials, such as plastic, be avoided.
Since static electricity is a surface phenomenon, materials can also be classified by
their surface resistivity measured in ohms per square. The table below lists the
surface resistivity of various classes of material.
Surface Resistively Table
Location and Air Current Requirements
The XPert Bulk Powder Enclosure has been designed to contain hazardous
powders by negating typical cross drafts and movements within the opening. Air
movement does not affect most modern balances with draft shields. However, as a
precautionary measure of safety and a higher level of quality management, it is
recommended that the enclosure be placed in such an area to avoid:
High traffic areas where walking might cause an air disturbance or be a
nuisance to balance readings.
Overhead or wall HVAC diffusers, fans, radiators or other lab equipment
producing air currents.
Next to doorways or windows that may be opened.
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 for Bulk Powder
Enclosures
The exhaust connection has been designed to accept a 2" x 10" (5.1cm x 25.4cm)
nominal exhaust collar. Labconco offers accessory transition adapters for the top
exhaust connection to either a 5" dia. hose or 6" dia. duct. When using the
accessory FilterMate Portable Exhausters, it requires the 5" Transition Adapter
3912400 which is sold with the FilterMate. Multiple FilterMate Portable
Exhausters require the airflow to be properly balanced. The 5', 6' and 8' enclosures
require two or three FilterMate Portable Exhausters dependent on face velocity and
size. See the following chart and refer to Chapter 3 for installation startup. See
Chapter 7 for ordering any of these accessories, FilterMate Portable Exhausters or
remote blowers.
Only one exhaust connection is required for the 5' and 6' enclosures when
connecting to house exhaust. Two exhaust connections are required for the 8'
enclosure when connecting to house exhaust. A 3981600 Exhaust Transition (6" x
6" x 8") may be used for the 8' enclosure connected to house exhaust. Data for the
exhaust volume and enclosure static pressure loss is listed for each enclosure
model at face velocities of 60, 80 and 100 fpm.
Proper blower selection can be determined from these exhaust requirements and
the total system static pressure loss. The enclosure must be connected to either a
dedicated blower, a house exhaust system or dedicated filtered exhausters, such as
FilterMate Portable Exhausters. Labconco offers accessory remote blowers and
FilterMate Portable Exhausters listed in Chapter 7.

Exhaust and Blower Requirements
Bulk Powder Filtered System
The XPert Bulk Powder Filtered Balance System uses an integral motorized
impeller to draw room air past the operator and through the enclosure. This
contaminated air is then pulled through the rear perforated baffle and 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 located under the exhaust diffuser screen to protect against
nuisance odors.
The HEPA-filtered exhaust air can be re-circulated into the laboratory or exhausted
outside with the addition of the Thimble Exhaust Connection and remote blower
listed in Chapter 7.
Bulk Powder Filtered Station
The XPert Bulk Powder Filtered Balance Station does not include the motorized
impeller and must be exhausted to the outside by a remote blower. The remote
blower may be activated from the blower switch on the enclosure. See Electrical
Requirements in Chapter 2 and Electrical Supply Connections in Chapter 3. Only
one 10" dia. exhaust connection is required for the 5' and 6' XPert Filtered Balance
Stations to exhaust to the outside.
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.
Proper blower selection may 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 filtered enclosures. See
Chapter 7 for accessory Adjustable Damper ordering information.

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 rated for 115V, 12A or 230V, 6A should be
nearby for connecting the XPert Bulk Powder Enclosure. Other equipment, such as
a balance, can be connected to the four-plex electrical box located underneath the
stainless steel work surface. The four-plex electrical box has four outlets rated at
115V, 12 A or 230V, 6 A. The XPert Filtered System/Station or accessory
FilterMate Portable Exhausters can also be powered through the four-plex
electrical box for your convenience. The enclosures include iris pass-through to
allow electrical cords through the back of the enclosure without leaving a large
hole for contaminants to escape.
XPert Station Only
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 with
wires that are terminated in the junction box behind the front panel. We
recommend a maximum amperage of 9 amps, 115V or 4.5 amps, 230V for this
circuit to the remote blower. Please refer to the wiring diagram on the unit.
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.
Leave 6-12" around the enclosure for proper airflow.

AUTHORIZATION OF LABCONCO. UNAUTHORIZED
RETURNS WILL NOT BE ACCEPTED.
IF ENCLOSURE WAS DAMAGED IN TRANSIT, YOU MUST
FILE A CLAIM DIRECTLY WITH THE FREIGHT CARRIER.
LABCONCO CORPORATION AND ITS DEALERS ARE NOT
RESPONSIBLE FOR SHIPPING DAMAGES.
Do not discard the packing material until you have checked all of the components
and tested the unit.
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 Enclosure and Work Surface on the
Lift Stand
Use caution when lifting or moving the upper enclosure or lift
stand. A hydraulic lift, electric lift or forklift is highly
recommended.
See Figure 3-1 for installation.
1. The lift stand has leveling feet to adjust the height. Be sure the lift stand
height will allow the transfer caddy to latch properly. The lower face of the
transfer cart’s square handle must be placed level with the lower side of the
2" sq. frame on the lift stand. This adjustment allows the transfer cart to
engage properly. (see Figure 3-1)
2. The stainless steel work surface and upper portion of the enclosure are
shipped as one unit and connected by fasteners. Slide both items as one unit
onto the lift stand. It is easy to do this by elevating both items with a
hydraulic lift table or forklift.
