8.2 Replacing the Gas Cylinder
SERVICE!
This task should be performed by qualified personnel only.
We advise to replace the gas cylinder as soon as it reaches 20 bar. The cylinder pressure can
be checked using either the side window or by opening the side cover and reading the
indicator (the left indicator in case of using the FM53 gas regulator).
Gas circuit
The gas cylinder (1) is
connected to the
instrument gas inlet (2)
fast connector. The T
(4) distributes the gas
in the detector (3) and
the external gas inlet
(5). The detector out (6)
is connected to the
micro-leak valve (7).
This one is connected
to the isolating valve (8)
and go to external
exhaust (9). The last
circuit is the
overpressure line from
the safety valve (10) to
external exhaust (11).
CAUTION!
The gas leak valve (7) is adjusted in the factory and should not be modified. It allows
controlling the right consumption of gas, allowing an optimum regeneration of the
gas inside detector.
