OPERATING PROCEDURES (Continued)
b.
Sampling
(1) Attach the flexible extension tube (figure 7, 5) to the monitor housing assembly (23).
(2) Verify the three position lever (figure 8, 9) is in the STOP position.
(3) Separate the monitor housing (10) and install the monitor (11). Reassemble the monitor housing (10).
(4) Connect the attached monitor housing bypass line (12) to the valve body (13) on top of the monitor housing
(10).
(5) Place the 1000 ml sample bottle (figure 7, 19) near the filtration module and monitor housing assembly (23).
(6) Place the monitor housing assembly open line (figure 8, 14) into the 1000 ml sample bottle (figure 7, 19).
WARNING
The filtration module may be under pressure during the next step. Wear proper safety
equipment. Prevent fuel from spilling on the ground. Use rags to prevent fuel from spraying
on personnel and equipment. Death or personal injury may result.
(7) Attach the monitor housing assembly (23) to the filtration module sample port quick disconnect.
(8) Connect monitor housing assembly (23) ground cables to the ground point on the filtration module.
(9) Move the three position lever (figure 8, 9) on the monitor housing to FLUSH. Flush the monitor (11) assembly
immediately prior to sampling. Displace the sampling line with at least two volumes of test fuel. Capture
displaced fuel in the 1000 ml sample bottle (figure 7, 19).
(10) Disconnect the monitor housing bypass line (figure 8, 12) from valve body (13) on top of monitor housing (10).
(11) Place the three position lever (9) on the monitor housing (10) to STOP. Remove the monitor (11) from the
monitor housing (10), open the monitor (11) and use tweezers (figure 7, 12) to insert a new test pad (14),
making sure that the treated side of the pad, (ORANGE), is facing upstream, to the inlet side of the monitor
(figure 8, 11).
(12) Reassemble the monitor housing (10) and connect the monitor housing bypass line (12) to the valve body (13).
(13) Place the three position lever (9) on the monitor housing (10) to the TEST position. Pass 500 ml of fuel through
the test pad (figure 7, 14). Accurately measure the test sample quantity. The normal volume of test fuel is 500
ml. Place the three position lever (figure 8, 9) on the monitor housing (10) to STOP.
WARNING
Use caution when disconnecting the flexible extension tube from the filtration module. Use
rags to prevent fuel from spraying on personnel or equipment. Death or personal injury
may result.
(14) Disconnect the flexible extension tube (figure 7, 5) from the filtration module.
