INFICON Explorer Portable Gas Chromatograph - Manual (Page 41)

Introduction
5. Turn the filling station valve so that it points towards the cylinder.
A steady flow of gas will be heard escaping from the end of the flexible hose.
This serves to purge the hose of any impurities.
6. Return the filling station valve to point away from the cylinder.
7. Hold the knurled collar of the Explorer refill port and slide it down towards the
top panel.
8. Insert the fitting at the end of the flexible hose into the refill port until it seats
against the port.
You will hear a click.
9. Release the knurled collar and allow it to slide up to its original position.
10. Turn the filling station valve so that it once again points towards the cylinder
and watch the pressure increase on the cylinder contents gauge on
Explorer’s side panel.
WARNING
Do not leave Explorer unattended while filling the internal cylinder.
NOTE: When the cylinder contents indicates approximately 1500 psig, the pressure relief
valve on the filling station will begin venting and prevent any further increase. The
contents pressure indicated MUST NOT exceed 1800 psig and the 3-way valve
should be switched before this occurs.
11. Turn the filling station valve handle to point away from the cylinder to allow
high pressure gas trapped in the flexible hose to escape.
A check valve in
Explorer prevents gas in the cylinder from escaping.
12. Close the gas cylinder valve.
