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.

Do not use any detachable power cord that is not adequately rated
for the unit.

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
