Connecting the Electrical Supply
A four-plex electrical box with four outlets is located under the stainless work
surface. It is rated at 115V, 12 amps or 230V, 6 amps. The four-plex electrical box
is a convenience for connecting the upper XPert Filtered Balance System or
Station, the main electrical hydraulic lift, accessory FilterMate Portable
Exhausters, airflow monitor, balance and other accessories. Simply connect the
electrical box power inlet to a standard duplex receptacle located nearby. Please
review Chapter 2 for electrical prerequisites. See Figure 3-1 for location.
All wiring for the building requires a licensed electrician and
should conform to all local codes.
Do not use any detachable power cord that is not adequately
rated for the unit.

Setting the Face Velocity
The face velocity should be adjusted from 60 to 100 fpm for all weighing
operations. Consult your safety officer for airflow recommendations for your
applications. Refer to the manual for your particular model. Depending on your
specific model, face velocities can be set in numerous ways such as through the
remote blower, accessory FilterMate Portable Exhausters for the XPert Bulk
Powder Enclosure or through the built-in motorized impeller for the XPert Bulk
Powder System.
Sealing the Upper Enclosure to the Work Surface
When the upper 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 clear bead of silicone sealant is recommended to seal the
enclosure to the work surface. The sealant also provides support.
Validating the Bulk Powder Enclosure
The XPert Bulk Powder Enclosure has been tested at the factory 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 (lmp); AM <0.05 (consult Labconco
for individual ratings). For additional validation, Labconco had independent testing
performed to validate the enclosures using sodium naproxen powder for
containment. For copies of these independent validation reports, contact Labconco.
Face velocity profiles and smoke testing should be performed
frequently per your organization’s quality system to ensure safe
performance.
