Before proceeding, check the H20 and O2
readings in the upperleft corner of the
display and verify that the values are less
than or equal to 0.1.
If the values are not as
indicated in A , please
contact a LSM.
To light the work area
within the box, touch the
“Boxlight” control on the
panel.
There are two antechambers on this
model, a small forward chamber and
a larger one toward the rear.
To load materials into the box, first verify
the pressure gauge on the chamber is
reading 0, the inner door is closed, and
the valve is in the closed position. 6
Open the outer door by turning the knob
in the center. Then slide the tray out and
place materials on it. When the chaber is
loaded, slide the tray back in and reseal
the outer door.

Evacuate the small chamber by
turning the valve to “evacuate”
as indicated by the diagram
below the pressure gauge.
Once the pressure gauge has settled,
allow 3 minutes for non-pourous and 12
hours for pourous materials.
Refill the chamber by turning the valve to
“refill,” as indicated by the diagram. For
non-porous materials, wait for the gauge
to settle at the halfway point. For porous
materials, wait for the gauge to settle at 0.
For non-porous materials, repeat 2 more
times with 3 minute evacuation cycles,
refilling the chamber halfway then, finally
to atmospheric pressure (0). For porous
materials, repeat the procedure one more
time, waiting another 12 hours for
evacuation.
Turn the valve to the “closed” position
and open the inside antechamber door,
slide the tray out, remove materials, then
close the chamber.
The procedure for the large
antechamber is the same as for the
small except the non-porous
materials should have 5 minutes
during evacuation instead of 3.
