not necessary to calibrate ow with a casse e in line.
2. Remove and retain sealing tabs from casse e inlet and outlet.
3. Connect casse e outlet to pump inlet.
a. Direct method: If pump accommodates direct mounting, insert casse e
adapter into pump inlet and push casse e outlet onto bowl end of
adapter.
b. Indirect method: Use 1/2-in ID tubing to connect casse 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 o pump, remove casse e, and reseal with
sealing tabs.

area samples, and blanks in a corrugated box and ship to a laboratory for
analysis.
