7.1 When all of the tubing connections have been
completed, close the purge valve on the front of the
sampler probe body. Open the sample probe
supply valve to allow pipeline pressure into the
sampler. Check all connections using a liquid leak
detector.
7.2 Adjust the filter/regulator from the following
ranges:
Pipeline Pressure
Actuation Pressure
10 psig (0.69 Bar) to
50 psig (3.5 Bar)
Use Full P/L Pressure
Pipeline Pressure
50 psig (3.5 Bar) to
700 psig (48 Bar)
50 psig (3.5 Bar)
Over 700 psig (48 Bar) to
1500 psig (103.4 Bar)
65 psig (4.5 Bar)
7.3 Turn the stroke adjustment knob on the top of
the pump counterclockwise to set the pump
displacement at .4cc/stroke.
7.4 Move all of the mode switches on the Z-65 to
their off positions.
7.5 Move both timer/counter dials to the 0 position
(00 minutes).
7.6 Move mode switches 1, 2 and 3 to the on
position. The pump will begin stroking once every 2
seconds in a diagnostic test mode.
7.7 Allow the sampler to operate until pipeline
pressure plus is achieved at the sample discharge.
7.8 Return the mode switches to their off positions.
7.9 Check all connections from the sampler dis-
charge to the connection on the sample cylinder
using a liquid leak detector.
7.10 If no leaks are found, the pump and tubing
should be considered tested and functional.
NOTE: Black indicates
the switch position.
