If a gas other than Ar is connected, the system configuration must be
changed accordingly. If air is being used, the port is left unconnected but
the system configuration must still be changed. See instructions for con-
figuring Gas 3 later in this chapter.
Attaching Gas Lines
Attach each of the gas lines to the appropriate connector (Swagelock compression
fitting for 1/8” OD tube) and leave the cylinder bottle valves closed until
after
the
gas line purging process has been completed.
The gas lines may be connected using either the gas lines and adapters supplied
with the unit, or a customer-supplied 1/8” OD tube gas line.
The Gas 2 (H
2
) inlet has an 0.5 micron filter attached via a short length of stain-
less steel tubing. The gas line from the H
2
regulator should be connected to the
inlet of this filter as shown in the picture below.
