OPERATING PROCEDURES (Continued)
Ensure that the monitor housing bypass line (6) is connected to the valve body on top of the assembly.
Place the monitor housing assembly open line (7) in a container of at least 1.3 gal (5 l) capacity.
Connect all ground clips to the filter separator ground point.
Verify the three position lever (figure 9, 1) is in the OFF position.
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.
m. Attach the monitor housing assembly (figure 7, 23) to the filtration module sample port quick disconnect fitting.
Position the three position lever (1) to FLUSH. Displace the sampling line with 0.5 gal (2 l) of fuel. Capture
displaced fuel in a 1.3 gal (5 l) container.
When 0.5 gal (2 l) of fuel have been collected, move the three position lever (1) to the TEST position. Take a fuel
sample of no more than 1 qt (1 l).
When the required amount of fuel is collected, place the three position lever (1) in the OFF position.
The one minute wait period in the next step is required as a precaution against electrostatic
discharge. A static discharge from any system component could ignite the fuel or cause an
explosion of fuel vapors. Do not operate the system until it has first been grounded properly.
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
After sampling is completed, allow one minute to pass, then disconnect the monitor housing assembly (figure 7, 23)
from the sample connection on the filtration module.
Remove the monitor (figure 9, 3) from the monitor housing (2) and attach the syringe (8) to the lower opening
(spiderweb side) of the monitor (3).
Pull outward on the syringe (8) handle to draw residual fuel from the monitor (3). If fuel remains in the monitor (3),
disconnect the syringe (8) and expel the collected fuel into a suitable container. Repeat the procedure as necessary
to withdraw all the fuel from the monitor (3).
If the gravimetric method of contamination is to be used, proceed to step u. If the color rating method is to be used:
(1) Use the tweezers (figure 7, 12) to pry off the top of the monitor (20).
(2) Use the tweezers (12) to lift the test pad from the monitor (20).
(3) Dry the test pad by placing on absorbent paper and blotting until the test pad is as dry as possible.
