g.
Flush the inlet hose by turning the three-way valve (1) to the FLUSH position: the valve arm is horizontal to the
base of the valve (2). Pass at least 3.2 quarts (3 or more liters) into a 5 gallon receptacle to remove contaminants from
the inlet valve. (figure 2-6)

h.
Take a sample by holding the sampler in an upright (vertical) position, turn the threeway valve (1) to the TEST
position. Allow no more than 1 liter (1.0 qt) to flow through the monitor. Record the sample volume for reporting. When
the collection is completed turn the three-way valve to the off position before turning off the system pump. Remove the
sampler from the system fitting and replace the protective cap and plug. (figure 2-7)
CAUTION
Some pumping systems (e.g. aircraft refuelers) develop a vacuum when closed which can
cause backflow and rupture the monitor filter, rendering the test ineffective.

i.
Disconnect the bypass hose (1) from the side of the sampler and unscrew the sampler base (2) from the sampler
cover. Hold the sampler in an upright position and remove the monitor (3). (figure 2-8)
