2.
Attach tubing to sampling pump by inserting tubing through "T" handle
opening.

threads, and tighten "T" handle.
3.
Attach the bottle to the sampling pump.
4.
Carefully insert tubing into reservoir.
Do not allow the tubing to
touch the bottom or sides of the reservoir, since any sludge entering the
tubing will contaminate the sample.

bottle. Fill the bottle to approximately 1/2 inch from the top.
Depress
the vacuum relief valve (on top of pump) to stop flow.

Loosen "T" handle and remove tubing
from pump. Discard tubing.
