6.4.4 Installation of an External Gas Cylinder
The gas regulator has to be mounted on the gas cylinder (be careful, the thread is
anti-clockwise). If the gas regulator is not shipped with the instrument, it is the responsibility
of the user to obtain and install the regulator locally as well as a safe ty valve (preloaded to
max 6.5 Bar) on the input gas circuit to avoid any overpressure inside of th e instrument.
A feedthrough with a female quick fitting is located on the back panel
and labeled “GAS IN”.
A short hose with a 6 mm diameter with a male quick fitting already
mounted is shipped with the instrument.
Connect the hose to the gas regulator. The connector is a standard
Swagelok gas connector.
1.
Open the gas cylinder and slightly open the gas regulator in order to have a small gas
flow.
2.
Connect the long hose male fitting in the input receptacle “GAS IN” located on the back
panel.
3.
Adjust the outlet gas pressure on the regulator to the recommended value (6 Bar).
If the gas pressure is set to a too high value, a purging connector is located inside the
instrument. Switch OFF the instrument. To access the purging connector “PURGE”, remove
the right side panel with the window. To decrease the pressure, close the gas regulator and
insert a male quick fitting in the purging connector (consisting of a female quick fitting
receptacle) for a few second. Increase the pressure again by opening slowly the gas
regulator. Remount the side panel of the instrument.
