5 Press the POWER button on the membrane panel of the evacuator.
6 Press the up or down arrow button to set the suction control rate to 20%.
Each time either arrow button is pressed, the suction will increase or
decrease by 10%. When two lights are lit on the suction control indicator,
the actual air flow is the value between the two illuminated percentages.
7 Verify that the filter flow gauge reads less than 2.4 inches of H
2
O
(Figure C-5 on page 287).
For a new filter, the gauge should read 1.1–1.4 inches of H
2
O. As the filter
is used, the reading will increase. If the gauge reads 2.4 inches of H
2
O or
greater, replace the filter. See Replacing the ULPA Filter on page 290.
Do not set the suction control rate above 20%. Higher rates could affect
the stability of the side streams.
