6.4.4 ARL EQUINOX 5000/5500: 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 safety valve (preloaded to
max 6.5 bar) on the input gas circuit to avoid any overpressure inside of the 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 re
ceptacle “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, the gas output “OUT” on the detector has to be
disconnected and it will be used to decrease the gas pressure. To decrease the pressure,
close the gas regulator and insert but not completely the male quick fitting of the output gas
hose of the detector. Let some gas to flow for a few second. Increase the pressure again by
opening slowly
the gas regulator. Remount the output gas hose on the “OUT” connector on
the detector.
