6.3 Pump Maintenance
WARNING
Fuels and solvents are flammable and may cause
irritation to the eyes or skin. Wear protective gog-
gles, gloves, and an apron; avoid contact with skin,
eyes, and clothing. Use in well ventilated areas and
keep away from heat or flame. Follow all Material
Safety Data Sheet (MSDS), Hazardous Materials
Identification System (HMIS), ISO 9000, Lab Stan-
dard Operating Procedures (SOP), and related in-
structions. Failure to comply may result in person-
nel injury or death.
Air in the lines is indicated by visible air pockets in the
sample output line, the lack of fuel being expelled; or
the lack of a steady stream of fuel expelled through the
sample-out line while the pump is running (assuming
fluid is in the sample beaker and the supply in line is
properly installed). It is recommended the first attempt to
free the system of air is to run the automated 'Prime'. If af-
ter running the 'Prime' for 2-3 minutes and a steady fluid
flow is not achieved, the automated 'Purge' should be
used. Should the 'Purge' not produce a steady flow the
manual prime pump method can be used. Access the
automated methods through the maintenance software
screen. The 'Maintenance' screen is accessed from the
'Main' screen

6.3.1 Prime Pump
Select the Prime Pump button on the maintenance screen
. Before beginning the Prime Pump operation
[Figure 58]
be sure the sample beaker has plenty of fluid, 250 ml
allows for 15 minutes of priming. Attach the sample-in
line properly, placing the filter end into the beaker. At-
tach the sample-out line and be sure there is a beaker
under the properly attached sample-out line. Pressing
the Start button begins an automated prime pump se-
quence
. The appropriate valves are open and
[Figure 59]
closed as needed as can be seen by the lighted Digital
Point (green=open, red=closed). The pump is adjusted
to a flow rate of 9 ml/minute during this prime. The Status
bar returns feedback during the prime sequence. There
is no time limit to the prime sequence and the operator
must press the Stop button to end the pump priming.
Watch the fuel flow into the outlet beaker. When a steady
stream is reached (no air in the line) the priming is suc-
cessful. Should air pockets still be visible in the lines,
proceed to the purge sequence. If the prime pump did
remove all air pockets, dispose of the fuel properly and
begin testing.
