1. Select a fl ow rate (see Flow Rate Guide on back) and calibrate pump fl ow rate.
VersaTrap ® Cassett es do not produce signifi cant back pressure, therefore, it is
not necessary to calibrate fl ow with a cassett e in line.
2. Remove and retain sealing tabs from cassett e inlet and outlet.
3. Connect cassett e outlet to pump inlet.
a. Direct method: If pump accommodates direct mounting, insert cassett e
adapter into pump inlet and push cassett e outlet onto bowl end of
adapter.
b. Indirect method: Use 1/2-in ID tubing to connect cassett e outlet to pump
inlet.
4. Turn on sample pump and sample for appropriate sampling time. See
Sampling Interval Guide on back.
5. When sampling is complete, turn off pump, remove cassett e, and reseal with
sealing tabs.
6. Place sample cassett es, outdoor background samples, non-complaint
area samples, and blanks in a corrugated box and ship to a laboratory for
analysis.
