WARNING
Do not stand in front of valve outlet when open-
ing.
2. Each cylinder must be equipped with an adjustable
high-pressure regulator capable of outlet pressures up
to 100 psi (6.9 bar) maximum and flows of up to 400
scfh (188.7 lpm).
CAUTION
Pressure should be set at 100 psi (6.9 bar) at the
high pressure gas cylinder regulator.
3. When using gas cylinders as the plasma and second-
ary gas supplies the connections will depend on the
number of cylinders used. Refer to one of the follow-
ing procedures and make the gas connections.
• Using Single Gas Cylinder for Plasma and Sec-
ondary Gas
If the Plasma and Secondary gas source are to be
the same and will use the same high pressure cyl-
inder, connect the gas regulator supply hose from
the gas cylinder to the Power Supply per the fol-
lowing:
a. Remove the Plasma and Secondary Hoses
from the Inert-B Fitting at the Plasma and Sec-
ondary Regulator/Filter Assemblies of the
Power Supply.
b. Remove the factory installed Two Stage Air
Line Filter Assembly and gas supply hoses
from the Power Supply.
c. On the Two Stage Air Line Filter remove the
two hoses and the T-Fitting at the output port
(OUT).

If the Plasma and Secondary gases will be differ-
ent or two separate high pressure cylinders are to
be used, connect the gas regulator supply hoses
to the Power Supply per the following:
a. Remove the Plasma and Secondary Hoses
from the Inert-B Fitting at the Plasma and Sec-
ondary Regulator/Filter Assemblies of the
Power Supply.
b. Connect the customer supplied gas cylinder
supply hose from the plasma gas source di-
rectly to the input fitting at the PLASMA air
regulator of the Power Supply.
c. Connect the customer supplied gas cylinder
supply hose from the secondary gas source di-
rectly to the input fitting at the SECONDARY
air regulator of the Power Supply..
