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
Under 700 psig (48 Bar)
50 psig (3.5 Bar)
Over 700 psig (48 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 the pipeline
pressure plus 100 psi (6.9 Bar) is achieved at the
sample discharge.
7.8 Return the mode switches to their off positions.
7.9 Check all connections from the sampler
discharge 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.
